Answer:
Average income for the remaining 8 months = $2,111.25
Step-by-step explanation:
Given:
Average income of 4 months = $1,420.25
Annual average income = $1,780.75
Find:
Average income of 8 months
Computation:
⇒ Annual average income = [Average income of 4 months + Average income of 8 months] / 2
⇒ $1,780.75 = [$1,420.25 + Average income of 8 months] / 2
⇒ $3,561.5 = $1,420.25 + Average income of 8 months
⇒ Average income of 8 months = $3,561.5 - $1,420.25
Average income of 8 months = $2,111.25

Rayan Company has 420, 000 shares of $ 10 par. 3 value ordinary shares outstanding. During the year Rayan declared a 5% share dividend when the market price of the shares was $ 36 per share. Three months later Rayan declared a $. 60 per share cash dividend. As a result of the dividends declared during the year, retained earnings [* decreased by
Answer:
The retained earnings decreased by $1,020,600
Step-by-step explanation:
Given that Rayan Company has 420,000 shares of $ 10 par. Rayan then declared a 5% share dividend when the market price of the shares was $36 per share.
Let's calculate the shares issued as stock dividends below:
Issued shares = stock dividends * outstanding shares
= 5% * 420,000
= 21,000
21,000 shares were issued.
Let's calculate the stock dividends.
Stock dividends = issued shares * market price per share
= 21,000 * $36
= $756,000
Stock dividends is $756,000
Let's calculate the amount of cash dividends, since the company declared a $0.60 per share cash dividend after 3 months. We have:
Cash dividend = cash dividend per share * new number of shares.
= $0.60 * (420,000 + 21,000)
= $0.60 * 441,000
= $264,600
Cash dividends paid is $264,600
The find the decrease in retained earnings, we have:
Decrease in Retained earnings = cost of stock dividend + cash dividend.
= $756,000 + $264,600
= $1,020,600
Therefore, the retained earnings decreased by $1,020,600

Find the range of f(x) = 3x + 2 for the domain = {1,2,3}.
Answer:
Range = {5, 8, 11}
Step-by-step explanation:
On the function f(x) = 3x + 2
For the first domain, when x = 1, f(x) = 3(1) + 2 = 3 + 2 = 5
For the second, when x = 2, f(x) = 3(2) + 2 = 6 + 2 = 8
For the third domain, when x = 3, f(x) = 3(3) + 2 = 9 + 2 = 11
Which triangle is similar to triangle abc?
the one that has 65 and 54, 3rd one
Answer:
Triangle three(bottom left corner)
Step-by-step explanation:
We know one angle must be 61, as it is given. The other angle can be found by subtracting 126 from 180.
So 180-126 = 54
So the two angles we are looking for are 61 and 54.
However none of the triangles have that those numbers, so we must find the third side. Using that the sum of the angles must be 180,
180-61-54 = 65
So the third angles must be 65
So now we look for the triangle that has 2 of the following: 65, 54, 61
Triangle 3 fits this.

Find sin(α) and cos(β), tan(α) and cot(β), and sec(α) and csc(β). The hypotenuse is 7 and side is 4.
The triangle is missing, so i have attached it.
Answer:
1)sin(α) = 4/7
2)cos(β) = 4/7
3)tan(α) = 4/√33
4)cot(β) = 4/√33
5)sec(α) = 7/√33
6)csc(β) = 7/√33
Step-by-step explanation:
(1) sin(α)
From trigonometric ratios, we know that sine of an angle in a right angle triangle = opposite/hypotenuse.
Now, in this question, the opposite side to α is 4 and the hypotenuse is 7. Thus, sin(α) = 4/7
2) cos(β)
Cosine of an angle = adjacent side/hypotenuse.
In the question, the adjacent side to the angle β is 4 and the hypotenuse is 7. Thus, cos(β) = 4/7
3)tan(α)
tan of an angle = opposite/adjacent side. The opposite side to α is 4, but the adjacent side is unknown.
Using the pythagoras theorem,
Adjacent side = √(7² - 4²)
Adjacent side = √(49 - 16)
Adjacent side = √33.
Thus, tan(α) = 4/√33
4) cot(β)
cot of an angle is the reciprocal of tangent of same angle.
The adjacent side to β is 4 while the opposite is √33.
So, tan(β) = (√33)/4
cot(β) = 1/tan(β)
cot(β) = 1/[(√33)/4]
cot(β) = 4/√33
5)sec(α)
sec of an angle is equal to one divided by cosine of that same angle, so it equals hypotenuse divided by the adjacent. The hypotenuse is 7 and the adjacent side to α is √33.
Thus, sec(α) = 1/cosα = 7/√33.
6) csc(β)
Csc of an angle is equal to one divided by sine of same angle, so it equals hypotenuses divided by the opposite. The hypotenuse is 7 and the opposite side to β is √33.
Thus, csc(β) = 1/sin(β) = 7/√33

The function g(x) is a transformation of f(x). If g(x) has a y-intercept of -2, which of the following functions could represent g(x)?
A. g(x) = f(x - 5)
B. g(x) = f(x) - 2
C. g(x) = f(x + 2)
D. g(x) = f(x) - 5
Answer:
D. g(x) = f(x) - 5
Step-by-step explanation:
To move the intercept to -2, one needs to translate the function down by 5 or left by 5. The first translation (down 5) would result in ...
g(x) = f(x) - 5 . . . . . . matches choice D
The second translation (left 5) would result in ...
g(x) = f(x+5) . . . . doesn't match any available choice
Answer: g(x) = f(x) - 5

The top most point of a pyramid is at the center of a cube The height of a cube is 10 inches what is the volume of the square pyramid inside the cube?
Answer:
166.67 in³
Step-by-step explanation:
If the top of the pyramid is at half of the height of 10 cm tall cube, the height of the pyramid (h) is 5 inches.
Assuming that the base of the pyramid is the same as the base of the cube, the volume of the square pyramid is given by:
[tex]V=\frac{1}{3}*B*h[/tex]
Where B is the area of the square base:
[tex]V=\frac{1}{3}*(10*10)*5\\ V=166.67\ in^3[/tex]
The volume of the square pyramid inside the cube is 166.67 in³.
Lauren drinks a variety of soft drinks. Over the past month, she has had 19 diet colas, 4 cans of lemonade, and 5 cans of root beer. a. Given this history, what is the probability that her next drink will be a diet cola? Lemonade? Root beer? b. What definition of probability should be used to answer this question?
Answer:
a.
Probability of Diet Cola = 19/28
Probability of Lemonade = 4/28
Probability of Root Beer = 5/28
b. Theoretical Probability
Step-by-step explanation:
Given
Diet Cola = 19
Lemonade = 4
Root Beer = 5
Required
Probability the her next drink will be
- Diet Cola
- Lemonade
- Root beer
To calculate the probability of each of the above, first we need to calculate the total number of drinks she's had
Total = Diet Cola + Lemonade + Root Beer
Total = 19 + 4 + 5
Total = 28
The probability that her next drink can be any of the above can then be calculated.
This is calculated by dividing each outcome by the total; as follows;
Probability of Diet Cola = 19/28
Probability of Lemonade = 4/28
Probability of Root Beer = 5/28
This type of probability is referred to as theoretical probability because it makes predictions base on previous occurrence of events.

How much money does the average professional football fan spend on food at a single football game? That question was posed to 60 randomly selected football fans. The sampled results show thatthe sample mean was $70.00 and prior sampling indicated that the population standard deviation was $17.50. Use this information to create a 95 percent confidence interval for the the average professional football fan spend on food at a single football game.
Answer:
$70.00 +/- $4.43
= ( $65.57, $74.43)
Therefore at 95% confidence interval (a,b) = ( $65.57, $74.43)
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Sample Mean x = $70.00
Standard deviation r = $17.50
Number of samples n = 60
Confidence interval = 95%
z(at 95% confidence) = 1.96
Substituting the values we have;
$70.00+/-1.96($17.50/√60)
$70.00+/-1.96($2.259240285287)
$70.00+/-$4.428110959163
$70.00+/-$4.43
= ( $65.57, $74.43)
Therefore at 95% confidence interval (a,b) = ( $65.57, $74.43)

Bilal's favorite colors are red and green.
He has 1 red shirt, 1 green shirt, 1 red hat, 1 green scarf, 1 red pair of pants, and
1 green pair of pants.
Bilal selects one of these garments at random. Let A be the event that he selects a green garment and let
B be the event that he chooses a scarf.
Answer:
P(A∪B) = 1/3
Step-by-step explanation:
Red Garments = 1 red shirt + 1 red hat + 1 red pairs of pants
Total Red Garments = 3
Green Garments = 1 green shirt + 1 green scarf + 1 green pairs of pants
Total Green Garments = 3
The total number of garments = Total Red Garments + Total Green Garments:
3 + 3 = 6
Let A be the event that he selects a green garment
P(A) = Number of required outcomes/Total number of possible outcomes
P(A) = 3/6
Let B be the event that he chooses a scarf
P(B) = 1/6
The objective here is to determine P(A or B) = P(A∪B)
Using the probability set notation theory:
P(A∪B) = P(A) + P(B) - P(A∩B)
P(A∩B) = Probability that a green pair of pant is chosen = P(A) - P(B)
= 3/6-1/6
= 2/6
P(A∪B) = 1/2 + 1/6 - 2/6
P(A∪B) = 2/6
P(A∪B) = 1/3

Pulse rates of adult females are listed in Data Set 1 "Body Data" in Appendix B. The lowest pulse rate is 36 beats per minute, the mean of the listed pulse rates is x = 74.0 beats per minute, and their standard deviation is s = 12.5 beats per minute. a. What is the difference between the pulse rate of 36 beats per minute and the mean pulse rate of the females? b. How many standard deviations is that [the difference found in part (a)]? c. Convert the pulse rate of 36 beats per minutes to a z score. d. If we consider pulse rates that convert to z scores between -2 and 2 to be neither significantly low nor significantly high, is the pulse rate of 36 beats per minute significant?
Answer:
Step-by-step explanation:
Hello!
The variable of interest is
X: pulse rate of a female adult. (beats/min)
Mean X[bar]= 74.0 beats/min
Standard deviation S= 12.5 beats/min
The lowest pulse rate is 36 beats/min
a)
The difference between the lowest pulse rate and the mean pulse for females is: 36 - 74= -38 beats/min
b)
To calculate how many standard deviations a value of the variable is from the mean, you have to subtract the mean from it and divide by the standard deviation:
(X-X[bar])/S= (36-74)/12.5= -3.04
The minimum pulse for female adults is -3.04 standard deviations away from the mean.
c)
The z score for 36 beats/min is -3.04
Considering the region of acceptance (-2; 2), the calculated value is below its lower limit, so you can conclude that the pulse rate 36 beats/min is significantly low.
I hope this helps!
