Analysis reveals that a company had a net increase in cash of $21,760 for the
current year. Net cash provided by operating activities was $19,600; net cash
used in investing activities was $10,800 and net cash provided by financing
activities was $12,960. If the year-end cash balance is $26,400, the beginning
cash balance was:
Answer:
Beginning Cash balance was $4,640.
Step-by-step explanation:
Net cash flow from operating activities = $19,600
Net cash flow used in investing activities = ($10,800)
Net cash provided by financing activities = $12,960
Net increase in cash $21,760
Beginning cash balance = Closing balance ($26,400) less net increase in cash ($21,760) = $4,640
The increase in cash represents the cash that was generated from operating, investing, and financing activities. These three activities are the classifications of an entity's activities. Operating activities are those activities that are normal to the business, i.e. activities the business undertakes under its mission. The investing activities arise from the purchase and sale of investments. These are not normal activities of most entities, except investment companies. Financing activities are activities engaged by an entity to raise finance, including the repayment of the borrowed funds plus interest.
Para ir a visitar a los abuelos Paula y Mario se ponen de acuerdo en que Paula vaya cada 5 días y Mario cada 6 días. Si coincidieron el 24 de diciembre,
a) ¿Cuándo volvieron a coincidir?
b) ¿Cuántas visitas habrá hecho cada uno?
Answer:
a) January 24(24 de Enero)
b) Paula will have made 5 visits(Paula habrá hecho 5 visitas). Mario will have made 4 visits(Mario habrá hecho 4 visitas).
Step-by-step explanation:
When two events, A and B, happen every x and y days, respectively, they will happen on the same day in each lcm(x,y) days. lcm(x,y) is the lesser common multiple of x and y which is not 0.
In this question:
Paula each 5 days
Mario each 6 days
Multiples of 5: {0, 5, 10, 15, 20,25,30, ...}
Multiples of 6: {0, 6, 12, 18, 24, 30, ...}
a) ¿Cuándo volvieron a coincidir?
lcm(5,6) = 30
30 days from December 24, which is January 24(24 de Enero).
b) ¿Cuántas visitas habrá hecho cada uno?
Paula visits each 5 days.
30 is 6th non-zero multiple of 5. This means that on January 24 will be her 6th visit. So she will have made 5 visits.
30 is the 5th non-zero multiple of 6. This means that on January 24 will be her 5th visit. So he will have made 4 visits.
what is the next term in the arithmetic sequence? 9,17,25,33,...
Answer:
41
Explanation:
To solve this problem we must first understand what the pattern is in the arithmetic sequence. Once we understand the pattern, we can then apply it to the final known term to find the next term.
Take a look at the arithmetic sequence given:
9, 17, 25, 33,...
Let's start by figuring out how they got the second term in the sequence. To do that, subtract the second term by the first term. This will reveal the pattern.
9 - first term
17 - second term
17 - 9 = 8
So, this means they added eight to get the next term. Therefore, the pattern should be 'add eight' to get the next term. Just to be sure the pattern we found is correct, apply it to the given arithmetic sequence.
9, 17, 25, 33,...
9 + 8 = 17
17 + 8 = 25
25 + 8 = 33
So, since 'adding eight' every time gives us the next term, the pattern is correct.
Finally, let's continue the pattern to find the next term.
9, 17, 25, 33,...
33 + 8 = 41
9, 17, 25, 33, 41,...
Therefore, the next term in the arithmetic sequence is 41.

1. Joy bought jewelry at a crafts fair. She bought a necklace for $8 and
some bracelets for $5 each. She spent $23 in all. Write and solve equation
that can be used to find the number of bracelets she bought
Answer:
5y + 8 < 23 and y < 3
2c - 3 = 9
Step-by-step explanation:
She bought a jewelry at a craft fair . The necklace is $8 and the bracelet is $5 each. Her total expenses is $23.
She bought a single necklace. The number of bracelet she bought is unknown but each of the bracelet she bought is $5 each. The number of bracelet she bought can be represented below.
Let
y = number of bracelet bought
Therefore, the cost of the total number of bracelet will be 5y
Recall the total expenses is $23
5y + 8 < 23 and y < 3
if you insert the value of y in the following inequalities the resulting value should be less than 23 so the value of y should be less than 3.

Error Analysis A math test asks the students to solve the inequality X-2<16, and then graph the
solutions. Mason said the solutions are x < 14 and graphed the solutions as shown below. Solve
the inequality and graph the solutions. What error might Mason have made?
What are the solutions?
Answer:
The solution is X<18
Step-by-step explanation:
When Mason was solving the inequality he subtracted two from the equation instead of adding two to solve for x.
X-2<16
X<18
Answer:
x < 18Step-by-step explanation:
x - 2 < 16
We eliminate 2 to isolate the variable, x by adding 2 to both sides. -2 + 2 = 0.
x < 18
We can test this because 17 is less than 18. Pretend x = 17
17 < 18✅
Mason subtracted 2, instead of adding 2.
In order to graph this, put an open circle at 18, and the arrow should point to the left.

A standard deck has 52 cards consisting of 26 black and 26 red cards. Three cards are dealt from a shuffled deck without replacement. Let A=first card red and B=second card red. Are A and B independent? Explain why or why not.
They aren't independent since the probability uses all the cards in the deck
So at the first deal we have the chance of 26/52 of getting a red card, at the second deal we have the chance of a 25/51 of getting another red card, so they aren't independent
A retail store had sales of $45000 in April and $56000 in May. The store employs eight full time workers who work 40 hours per week. In April the store also had seven part time workers at 10 hours per week, and in may the store had 9 part time workers at 15 hours per week. Using sales dollars as the measure for output, what is the percentage of change in productivity from April to May?
The percentage of change in productivity from April to May is found to be 6.66%.
Productivity ChangeWhat is meant by change in productivity?A change in labour productivity reflects an output change that cannot be accounted for by a change in the number of hours worked. The development of technology over time might lead to an increase in output per hour enhanced employee skills.
Step by step solutionStep 1: Productivity for month of AprilWe must first determine the number of man hours worked in April in order to compute the percentage change in productivity:
8 employs worked for 40 hours along with 7 employs worked for 10 hours in a week( total 4 weeks in April).
Input of April is,
= 8×40 + 7×10×4
= 1560 hours
To determine the productivity in April, divide the total sales by the number of man hours:
= 45000/1560
= 28.846
Step 2: Productivity for month of May8 employs worked for 40 hours along with 9 employs worked for 15 hours in a week( total 4 weeks in April).
Input of May is,
= 8×40 + 9×15×4
= 1820 hours
To determine the productivity in April, divide the total sales by the number of man hours:
= 56000/1820
= 30.769
Step 3: Calculate the total productivityFinding the difference between productivity in each month and dividing by April's productivity percentage yields the percent change in productivity:
= [tex]\frac{30769-28.846}{28.846}[/tex]×[tex]100[/tex]
= 6.66 %
Therefore, the productivity from April to May increased by 6.66%.

Calculate the standard score of the given X value, X=28.3, where μ=26.3 and σ=28.1 and indicate on the curve where z will be located. Round the standard score to two decimal places.
Answer:
Standard score z=0.07
Step-by-step explanation:
The z-score, or standard score, represents an equivalent value for X but in the standard normal distribution, where μ=0 and σ=1.
For X=28.3 in a normal distribution with μ=26.3 and σ=28.1, the standard score can be calculated as:
[tex]z=\dfrac{X-\mu}{\sigma}=\dfrac{28.3-26.3}{28.1}=\dfrac{2}{28.1}=0.07[/tex]
This value is 0.07 standard deviations right to the mean.
In the picture attached, we have located the z-score.

Calculate the slope between the two points: (7, –4), (7, 8)
Answer:
undefined
Step-by-step explanation:
We can find the slope by using the formula
m = (y2-y1)/(x2-x1)
m = (8 - -4)/97-7)
= (8+4)/(7-7)
= 12/0
We cannot divide by 0 so the slope is undefined

On moving day, Jorge needs to rent a truck. The length of the cargo space is 12 ft, and the height is 1 ft less than the width. The brochure indicates that the truck can hold 504 ft3. What are the dimensions of the cargo space? Assume that the cargo space is in the shape of a rectangular solid.
Answer:
12ft [tex]\times[/tex]7ft [tex]\times[/tex]6ft
Step-by-step explanation:
Given that truck can hold = 504 [tex]ft^{3}[/tex] i.e.
Volume, V = 504 [tex]ft^{3}[/tex]
Length of cargo space = 12 ft
Let width of cargo space = w ft
As per question statement:
Let height of cargo space = (w-1) ft
To find: The Dimensions of Cargo Space
Formula for Volume of Cargo Space:
V = Length [tex]\times[/tex] Width [tex]\times[/tex] Height
Putting the given values and conditions:
504 = 12 [tex]\times[/tex] [tex]w \times (w-1)[/tex]
[tex]\Rightarrow w(w-1) = \dfrac{504}{12}\\\Rightarrow w^{2} -w = 42\\\Rightarrow w^{2} -w - 42=0\\\Rightarrow w^{2} -7w +6w -42 =0\\\Rightarrow w(w -7) +6(w -7) =0\\\Rightarrow (w -7)(w+6) = 0\\\Rightarrow w =7, -6[/tex]
Dimensions can not be negative, so width, w = 7 ft
Height = (w-1) = 7-1 = 6 ft
So, the dimensions are 12ft [tex]\times[/tex]7ft [tex]\times[/tex]6ft.
In a restaurant 40% of the customers choose Chinese food while 65% opt for Pakistani food .if the restaurant is visited by 260 people then how many opt for both in quarter ? Ans is 39 please give the working ?
Answer:
13 ppl choose both
Step-by-step explanation:
Hello,
In a restaurant 40% of the customers choose Chinese food
while 65% opt for Pakistani food.
if the restaurant is visited by 260 people then how many opt for both ?
There are 260 people we need to compute
40% of 260 = 40*260/100 = 104 to know the customers choosing Chinese food
65% of 260 = 65 * 260/100 = 169 to know the customers choosing Pakistani food
There are ppl choosing both Chinese and Pakistani, let s note x
we can say that 104 + 169 -x = 260
so x = 273-260=13
in conclusion, 104-13=91 ppl choose Chinese food only
169-13=159 ppl choose Pakistani food only
13 ppl choose both
in total there are 91 + 159 + 13 = 260
hope this helps
The number of people who opt for both Chinese and Pakistani food is 13.
We have,
Let's denote the number of people who choose Chinese food as "C" and the number of people who choose Pakistani food as "P".
We are given that 40% of the customers choose Chinese food, which means
C = 40% of 260.
C = 0.4 * 260
C = 104
Similarly, we are given that 65% of the customers opt for Pakistani food, which means
P = 65% of 260.
P = 0.65 * 260
P = 169
Now, we need to determine the number of people who opt for both Chinese and Pakistani food.
To find this, we can use the principle of inclusion-exclusion.
The total number of people who opt for both is given by:
Total = C + P - Both
We know that the total number of customers is 260, so:
260 = 104 + 169 - Both
Rearranging the equation to solve for Both:
Both = 104 + 169 - 260
Both = 273 - 260
Both = 13
Therefore,
The number of people who opt for both Chinese and Pakistani food is 13.

a) What is the expected number of these tweets with no reaction?
b) What are the variance and standard deviation for the number of these tweets with no reaction?
Answer:
a) E(X) = 71
b) V(X) = 20.59
Sigma = 4.538
Step-by-step explanation:
The question is incomplete:
According to a 2010 study conducted by the Toronto-based social media analytics firm Sysomos, 71% of all tweets get no reaction. That is, these are tweets that are not replied to or retweeted (Sysomos website, January 5, 2015).
Suppose we randomly select 100 tweets.
a) What is the expected number of these tweets with no reaction?
b) What are the variance and standard deviation for the number of these tweets with no reaction?
This can be modeled with the binomial distribution, with sample size n=100 and p=0.71, as the probability of no reaction for each individual tweet.
The expected number of these tweets with no reaction can be calcualted as the mean of the binomial random variable with these parameters:
[tex]E(X)=n\cdot p=100\cdot 0.71=71[/tex]
The variance for the number of these tweets with no reaction can be calculated as the variance of the binomial distribution:
[tex]V(X)=np(1-p)=100\cdot0.71\cdot0.29=20.59[/tex]
Then, the standard deviation becomes:

A 100-gallon barrel, initially half-full of oil, develops a leak at the bottom. Let A(t) be the amount of oil in the barrel at time t. Suppose that the amount of oil is decreasing at a rate proportional to the product of the time elapsed and the amount of oil present in the barrel. The mathematical model is:___________.
(a) =kA, A(0) = 0
(b) A = ktA, A(O) = 50
(c) A tA, A(0) = 100
(d) A = két +A), A
(e) = 50 None of the above.
Answer:
the mathematical model is : [tex]-\frac{1}{A}= kt - \frac{1}{50}[/tex]
Step-by-step explanation:
Given that:
Let A(t) to be the amount of oil in the barrel at time t.
However; Suppose that the amount of oil is decreasing at a rate proportional to the product of the time elapsed and the amount of oil present in the barrel.
Then,
[tex]\frac{dA}{dt} \ \alpha \ A^2[/tex]
[tex]\frac{dA}{dt}= KA^2[/tex]
Initially the 100 -gallon barrel is half-full of oil
So, A(0) = 100/2 = 50
[tex]\frac{dA}{dt}= KA^2 \ \ \ \ \ \ :A(0)=50[/tex]
The variable is now being separated as:
[tex]\frac{dA}{A^2}=kdl[/tex]
Taking integral of both sides; we have:
[tex]\int\limits\frac{dA}{A^2}=\int\limits \ kdt[/tex]
[tex]-\frac{1}{A}= kt +C[/tex]
However; since A(0) = 50; Then
t = 0 ; A =50 in the above equation
[tex]-\frac{1}{50}= 0 +C[/tex]
[tex]C = - \frac{1}{50}[/tex]
Thus; the mathematical model is : [tex]-\frac{1}{A}= kt - \frac{1}{50}[/tex]
The six faces of a cube are painted black. The cube is then cut into [tex]5^3 = 125[/tex] smaller cubes, all the same size. One of the small cubes is chosen at random and rolled. What is the probability that when it lands, the face on the top is black?
Answer:
The probability that a randomly selected small cube is rolled and the face on the top is black is P=0.2.
Step-by-step explanation:
We have a cube, with the faces painted black, that each side is divided in 5, so we end up with 125 cubes.
We have to calculate the probability that a randomly selected cube is rolled and the face on the top is black.
This probability is equal to the proportion of black area in the total area of the cube.
We can define the side of the original cube as A=5a, being a the side of the small cubes.
The area that is painted black is equal to the sum of 6 squares of side A. In terms of a, that is:
[tex]S_b=6\cdot A^2=6\cdot(5a)^2=6\cdot25a^2=150a^2[/tex]
The total area of the 125 small cubes is:
[tex]S=125(6a^2)=750a^2[/tex]
Then, the ratio of black surface to the total surface is:
[tex]s_b/s=(150a^2)/(750a^2)=0.2[/tex]
Then, we can conclude that the probability that a randomly selected small cube is rolled and the face on the top is black is P=0.2.
