About 3% of the population has a particular genetic mutation. 600 people are randomly selected.
Find the mean for the number of people with the genetic mutation in such groups of 600.
The mean for the number of people with the genetic mutation in such groups of 600 is 18.
Given that,
About 3% of the population has a particular genetic mutation.
This means that for any group of people, 3% of the people has a particular genetic mutation.
This is a binomial distribution.
Probability that people having genetic mutation = 3% = 0.03
Random sample size = 600
Mean for a binomial distribution can be calculated as,
Mean = n × p
= 600 × 0.03
= 18
Hence the mean number of people having genetic mutation is 18.

During the late 1980s and the early 1990s the Pepsi Challenge was in full swing. During the challenge, participants were asked to taste cola from both Coke and Pepsi. Once they had tasted both drinks, the participants were asked to report which was better tasting. The results indicated that participants found Pepsi products to be better tasting. What is the dependent variable in this study? coruse hero psyc 255
Answer:
Taste
Step-by-step explanation:
In the challenge, participants were asked to taste cola from both Coke and Pepsi. They were to give a report on which of the two drinks tasted better.
The taste reported by the participants is dependent on the type of cola taken (either Coke or Pepsi).
Therefore, the taste is the dependent variable while the types of cola are the independent variables.
Mission Foods produces two flavors of tacos—chicken and fish—with the following characteristics.
Chicken Fish
Selling price per taco $ 3.90 $ 5.30
Variable cost per taco 1.95 2.65
Expected sales (tacos) 201,000 303,000
The total fixed costs for the company are $107,000.
Required:
a. What is the anticipated level of profits for the expected sales volumes?
b. Assuming that the product mix would be 42 percent chicken and 58 percent fish at the break-even point, compute the break-even volume using weighted-average contribution margin.
c. If the product sales mix were to change to four chicken tacos for each fish taco, what would be the new break-even volume?
a. To calculate the anticipated level of profits, we need to calculate the total revenue and total variable costs for each product, and then subtract the total variable costs and fixed costs from the total revenue.
Chicken:
Total revenue = $3.90 x 201,000 = $783,900
Total variable costs = $1.95 x 201,000 = $392,295
Contribution margin = $391,605
Fish:
Total revenue = $5.30 x 303,000 = $1,607,900
Total variable costs = $2.65 x 303,000 = $803,295
Contribution margin = $804,605
Total contribution margin = $391,605 + $804,605 = $1,196,210
Total fixed costs = $107,000
Anticipated profits = Total contribution margin - Total fixed costs = $1,196,210 - $107,000 = $1,089,210
b. Weighted-average contribution margin = (0.42 x $1.95) + (0.58 x $2.65) = $2.36
Break-even volume = Total fixed costs ÷ Weighted-average contribution margin = $107,000 ÷ $2.36 = 45,339 tacos
c. If the product sales mix changes to four chicken tacos for each fish taco, then the new product mix is 80% chicken and 20% fish.
Weighted-average contribution margin = (0.80 x $1.95) + (0.20 x $2.65) = $2.06
Break-even volume = Total fixed costs ÷ Weighted-average contribution margin = $107,000 ÷ $2.06 = 51,942 tacos
If f ( x ) is a linear function, f ( − 1 ) = 2 , and f ( 5 ) = − 5 , find an equation for f ( x ) . f ( x ) =__
show your work!
Step-by-step explanation:
Let's first find the slope
(-5-2)/(5--1) = -7/6
the equation should be
\(y = \frac{ - 7}{6} x + c\)
To find c, we replace X with -1 and Y with 2
c= 5/6
So the equation is
\(y = \frac{ - 7}{6} x + \frac{5}{6} \)
And if you multiply everything by 6 you get
6y = -7x +5
The RLX Company just paid a dividend of $2.85 per share on its stock. The dividends are expected to grow at a constant rate of 4.5 percent per year, indefinitely. Assume investors require a return of 10 percent on this stock. What is the current price?
The current stock price is $54.15.
Given that RLX Company just paid a dividend of $2.85 per share on its stock and dividends are expected to grow at a constant rate of 4.5 percent per year, indefinitely.
Stock valuation alludes to the valuation of the natural worth per portion of an organization's stock which can help the organization in deciding its reasonable worth in case of twisting up or consolidation. One of the models used to esteem the stock cost is the profit development model. It expects the cost of the stock to be the current worth representing things to come profits of the stock accepted to develop at a consistent rate.
Dividend (D0) = $2.85
Growth rate (g) = 4.5%
Required return (r) = 10%
Firstly, we have to calculate the value of the current stock price.
The current stock price can be calculated by using the dividend growing model.
\(\begin{aligned}\text{Current stock price}&=\frac{D_{0}\times(1+g)}{r-g}\\ &=\frac{2.85\times (1+0.045)}{0.10-0.045}\\ &=\frac{2.85\times 1.045}{0.055}\\ &=\frac{2.97825}{0.055}\\ &=54.15\end\)
Hence, the current stock price when dividend of $2.85 are expected to grow at a constant rate of 4.5 percent per year, indefinitely is $54.15.

Step-by-step explanation:
If MNOP is a square, you know that each angle is going to be 90°. To solve, let's first set each equation equal to 90°:
\(90 = 4t + 20\)
and
\(90 = 7f + 6\)
Then solve both equations:
\(90 = 4t + 20 \\ 70 = 4t \\ 17.5 = t\)

Slope =
y-intercept =
y =
The Slope is -4.
The y-intercept is 5.
The equation of the line isy = -4x + 5
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
x -6 -4 -2 0 2 4 6
y 29 21 13 5 -3 -11 -19
We can make ordered pairs:
(-6, 29), (-4, 21), (0, 5), and (2, -3).
Now,
Take any two ordered pairs.
(-6, 29( and (-4, 21)
m = (21 - 29) / (-4 + 6)
m = -8 / 2
m = -4
or
(0, 5) and (2, -3)
m = (-3 - 5) / (2 - 0)
m = -8/2
m = -4
So,
Slope = -4
Now,
We can make an equation from the table.
y = mx + c
Take any one ordered pair.
(0, 5) = (x, y)
5 = -4 x 0 + c
5 = 0 + c
c = 5
y-intercept = 5
So,
y = -4x + 5
Thus,
Slope = -4
y-intercept = 5
y = -4x + 5

21p+35q
please help me!
Answer:
Simplifying
21p + 35q = 0
Solving
21p + 35q = 0
Solving for variable 'p'.
Move all terms containing p to the left, all other terms to the right.
Add '-35q' to each side of the equation.
21p + 35q + -35q = 0 + -35q
Combine like terms: 35q + -35q = 0
21p + 0 = 0 + -35q
21p = 0 + -35q
Remove the zero:
21p = -35q
Divide each side by '21'.
p = -1.666666667q

Brandon bought a jacket on sale for $36. If the jacket originally cost $60, what was the percentage discount for the cost of the jacket?
Answer:
40% discount
Step-by-step explanation:
To find this remember the formula \(\frac{discount amount}{original price} = \frac{percent discount}{100}\)
To find the discount amount subtract $36 from $60 which is $24.
\(\frac{24}{60} = \frac{x}{100}\) next you have to cross multiply
24*100 = 2400 and 60*x = 60x
Now you have the equation 2400 = 60x
Divide both sides by 60 to isolate the variable
x = 40

What is linear equation in two variables?An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e. a and b respectively, are not equal to zero.
What is substitution method?The method in which, the value of one variable from one equation is substituted in the other equation. So that, a pair of the linear equation gets transformed into one linear equation with only one variable, which can then easily be solved. This method is called substitution method.
According to the given question we have
A linear equation in two variable
h = 3p + 5
So, the value of h when p = 7
Substitute, p = 7 in h = 3p + 5
⇒ h = (3 × 7) + 5
⇒ h = 21 + 5
⇒ h = 26
