A chocolatier makes 1,313 chocolate covered strawberries per day. The strawberries are packed into boxes. A large box contains 9 strawberries and a small box contains 4 strawberries. If the large boxes are filled first, how many small boxes are needed?
Answer:
2 small boxes
Step-by-step explanation:
The chocolatier makes 1313 chocolate covered strawberries.
The large boxes contains 9 strawberries and the small box contains 4 strawberries.
The large boxes are filled first.
We need to divide 1313 by 9 and find the remainder.
1313 / 9 = 145 remainder 8
This means that 145 large boxes will be needed and 8 strawberries will be left.
The number of small boxes needed is therefore:
8 / 4 = 2 boxes
the label on marc’s yogurt said that one serving provided 10 grams of fiber, which is 50% of the recommended daily amount. what is the total recommended daily amount of fiber?
Answer:
20 grams
Step-by-step explanation:
10 grams is 50%. 50% x 2= 100%. so you do 50/100=10/20, and you will get 2. Apply that to the 10, 10 x 2=20.
The sample space, S, of a coin being tossed three times is shown below, where H and T denote the coin landing on heads and tails respectively.
Answer:
The probability distribution for the number of heads occurring in three coin tosses are P(X1) = 1, P(X2)= 2/3, P(X3)= 2/3, P(X4)= 1/3, P(X5)= 2/3, P(X6)= 1/3, P(X7)= 1/3 and P(X8)= 0
Step-by-step explanation:
The question is incomplete. Here is the complete question;
The sample space, S, of a coin being tossed three times is shown below, where Hand T denote the coin
landing on heads and tails respectively.
S = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}
Let X = the number of times the coin comes up heads. What is the probability distribution for the number of heads occurring in three coin tosses?
Probability is the likelihood or chance that an event will occur.
Probability = expected outcome/total outcome of event
From the question given, the total number of sample space will be our total outcome during each toss = 3
If X is the number of times the coin comes up heads, the number of times the coin turn up all heads will be the expected outcome during each throw.
Probability distribution P(Xi)= [tex]\frac{n(Xi)}{n(S)}[/tex]
Xi is the probability that the head turns up at each throw.
n(Xi) is the expected outcome during each toss
n(S) is the total outcome during each toss
During the first throw, the head turns up three times (HHH), the probability that heads turns up ia 3/3 = 1
P(X1) = 1
During the second, third and fifth throw, the head turns up two times, the probability that heads turns up during this times will be 2/3
P(X2)= 2/3
P(X3)= 2/3
P(X5)= 2/3
During the fourth, sixth and seventh throw, the head turns up just once, the probability that heads turns up during this times will be 1/3
P(X4)= 1/3
P(X6)= 1/3
P(X7)= 1/3
Since no head turns up during the eight throw, the probability that heads turns up during this time will be 0/3 which is 0.
P(X8)= 0
The probability distribution for the number of heads occurring in three coin tosses are P(X1) = 1, P(X2)= 2/3, P(X3)= 2/3, P(X4)= 1/3, P(X5)= 2/3, P(X6)= 1/3, P(X7)= 1/3 and P(X8)= 0

Answer:
k=4
Step-by-step explanation:
y=3(1)-1
y=2
2=-2x+k
2=-2(1)+k
2=-2+k
4=k
Answer:
k = 4
Step-by-step explanation:
y = 3x -1
y = -2x+k
Set the two equations equal
3x -1 = -2x+k
Combine like terms
Add 2x to each side
3x+2x -1 =-2x+2x +k
5x - 1 = k
We know they are equal when x= 1
Let x=1
5*1 -1= k
5 -1= k
4 = k
A company that packages peanuts states that at a maximum 6% of the peanut shells contain no nuts. At random, 300 peanuts were selected and 21 of them were empty.
1.With a significance level of 1%, can the statement made by the company be accepted?
2.With the same sample percentage of empty nuts and 1 − α = 0.95, what sample size would be needed to estimate the proportion of nuts with an error of less than 1%?
Answer:
1) [tex]z=\frac{0.07 -0.06}{\sqrt{\frac{0.06(1-0.06)}{300}}}=0.729[/tex]
We can calculate the p value with the following formula:
[tex]p_v =2*P(z>0.729)=0.466[/tex]
The p value for this case is very high and using the significance level of 0.01 we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the statment makes sense.
2) [tex]n=\frac{\hat p (1-\hat p)}{(\frac{ME}{z})^2}[/tex] (b)
And replacing into equation (b) the values from part a we got:
[tex]n=\frac{0.06(1-0.06)}{(\frac{0.01}{1.96})^2}=2166.66[/tex]
And rounded up we have that n=2167
Step-by-step explanation:
Information given
n=300 represent the random sample taken
X=21 represent the number of peanuts empty
[tex]\hat p=\frac{21}{300}=0.07[/tex] estimated proportion of peanust empty
[tex]p_o=0.06[/tex] is the value to test
[tex]\alpha=0.05[/tex] represent the significance level
z would represent the statistic
[tex]p_v[/tex] represent the p value
Part 1
We want to test if the true proportion is 6% or no the system of hypothesis are:
Null hypothesis:[tex]p=0.06[/tex]
Alternative hypothesis:[tex]p \neq 0.06[/tex]
The statistic is given by:
[tex]z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}[/tex] (1)
Replacing the info given we got:
[tex]z=\frac{0.07 -0.06}{\sqrt{\frac{0.06(1-0.06)}{300}}}=0.729[/tex]
We can calculate the p value with the following formula:
[tex]p_v =2*P(z>0.729)=0.466[/tex]
The p value for this case is very high and using the significance level of 0.01 we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the statment makes sense.
Part 2
The margin of error for the proportion interval is given by this formula:
[tex] ME=z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}[/tex] (a)
And on this case we have that [tex]ME =\pm 0.01[/tex] and we are interested in order to find the value of n, if we solve n from equation (a) we got:
[tex]n=\frac{\hat p (1-\hat p)}{(\frac{ME}{z})^2}[/tex] (b)
And replacing into equation (b) the values from part a we got:
[tex]n=\frac{0.06(1-0.06)}{(\frac{0.01}{1.96})^2}=2166.66[/tex]
And rounded up we have that n=2167

A rectangle is removed from the middle of a larger rectangular shaped board. What is the area of the remaining board?
Answer:
The area of the remaining board is [(L × B) - (l × b)].
Step-by-step explanation:
Suppose the bigger rectangle is labelled as ABCD and the smaller rectangle is labelled as PQRS.
Consider that the length and breadth of the bigger rectangle are L and B respectively. And the length and breadth of the bigger rectangle are l and b respectively.
The area of any rectangle is:
Area = Length × Breadth
The area of the bigger rectangle is:
Area of ABCD = L × B
The area of the smaller rectangle is:
Area of PQRS = l × b
Then the area of the remaining board will be:
Area of remaining board = Area of ABCD - Area of PQRS
= (L × B) - (l × b)
Thus, the area of the remaining board is [(L × B) - (l × b)].

The Wall Street Journal reported that Walmart Stores Inc. is planning to lay off employees at its Sam's Club warehouse unit. Approximately half of the layoffs will be hourly employees (The Wall Street Journal, January 25-26, 2014). Suppose the following data represent the percentage of hourly employees laid off for Sam's Club stores.55 56 44 43 44 56 60 62 57 45 36 38 50 69 65a. Compute the mean and median percentage of hourly employees being laid off at these stores. Mean Medianb. Compute the first and third quartiles. First quartile Third quartilec. Compute the range and interquartile range. Range Interquartile ranged. Compute the variance and standard deviation. Round your answers to four decimal places. Variance Standard deviatione. Do the data contain any outliers
Answer:
Step-by-step explanation:
a) Rearranging the given data in ascending order, it becomes
36, 38, 43, 44, 44, 45, 50, 55, 56, 57, 56, 60, 62, 65, 69
n = 15
The mean = (55 + 56 + 44 + 43 + 44 + 56 + 60 + 62 + 57 + 45 + 36 + 38 + 50 + 69 + 65)/15 = 52
Median = 55
b) Range = 69 - 36 = 33
The median divides the data set into two halves, lower and upper. The median of the lower halve is the first quartile, Q1 while the median of the upper halve is the third quartile, Q3
First quartile, Q1 = 44
Third quartile, Q3 = 60
Inter quartile range, IQR = Q3 - Q1 = 60 - 44 = 16
Variance = (summation(x - mean)²/n
Variance = (55 - 52)^2 + (56 - 52)^2 + (44 - 52)^2 + (43 - 52)^2 + (44 - 52)^2 + (56 - 52)^2 + (60 - 52)^2 + (62 - 52)^2 + (57 - 52)^2 + (45 - 52)^2 + (36 - 52)^2 + (38 - 52)^2 + (50 - 52)^2 + (69 - 52)^2 + (65 - 52)^2/15
Variance = 93.467
Standard deviation = √variance
Standard deviation = √93.467 =
9.668
The data does not contain any outliers.

What is the solution set of |–x| = –10?
{10}
{–10}
{–10, 10}
no solution
Answer:
no solution
Step-by-step explanation:
Modular equation:
The modular of a function f(x)(|f(x)|) is the distance of f(x) to the origin.
In the case of a point, the modulus of the point is the distance to the origin.
If we have:
|f(x)| = a, it means that:
f(x) = a or f(x) = -a.
However
It is only true for non-negative values of a, since the modulus is a distance, which is a positive measure.
|–x| = –10
The modular is never a negative number, so it cannot be -10.
This means that there is no solution.

3) Check Explanation
Step-by-step explanation:

English Translation
Efraín has a rectangular land whose area is (120m² + 280m) as shown in the figure. According to these data, how much does side f measure?
a) 12 m² + 35
b) 15 m + 35 cm
c) 12 m + 35
d) 15 m + 35
3.- A child made four plasticine figures: two quadrangular prisms and two cylinders. In which figure did you occupy the most amount of modeling clay? JUSTIFY YOUR ANSWER
Solution
2) The area of a rectangle is given as
Area = Length × Breadth
Area = (120m² + 280m)
Length = f
Breadth = 8m
(120m² + 280m) = f × 8m
f = (120m² + 280m)/(8m)
f = (15m + 35)
Option D is correct.
f = (15m + 35)
3) For the second question, the images for the question and the dimensions of the figures aren't provided, hence, a very accurate answer can be provided. But without This, we can only speculate.
The figure that would use the most clay is the figure whose volume is the highest if the volumes of each of the figures are calculated.
Volume of a quadrangular prism = (Area of base) × (perpendicular height)
Volume of a cylinder = (Area of base) × (Height) = (πR² × H) = πR²H
So, it is in the evaluation of these volumes that the solution of this question is obtained.

What is the quotient? Negative StartFraction 3 over 8 EndFraction divided by negative one-fourth
Answer:
[tex]\dfrac{3}{2}[/tex]
Step-by-step explanation:
We are given 2 fractions.
1st fraction is Negative StartFraction 3 over 8
i.e.
[tex]-\dfrac{3}{8}[/tex]
2nd fraction is negative one-fourth
i.e.
[tex]-\dfrac{1}{4}[/tex]
We have to find the quotient when 1st fraction is divided by 2nd fraction.
Definition of quotient is given as:
Quotient is the result obtained when one number is divided by other number.
[tex]-\dfrac{3}{8} \div -\dfrac{1}{4} \text{ is to be calculated.}[/tex]
[tex]\div[/tex] is converted to [tex]\times[/tex] and the 2nd fraction is reversed i.e.
if the fraction is [tex]\frac{p}{q}[/tex] it becomes [tex]\frac{q}{p}[/tex] and the sign [tex]\div[/tex] is changed to [tex]\times[/tex].
Solving above:
[tex]-\dfrac{3}{8} \times -\dfrac{4}{1}\\ \text {Multiplication/Division of 2 negative number gives a positive number}\\\Rightarrow \dfrac{3}{2}[/tex]
So, the quotient is [tex]\frac{3}{2}[/tex].
