Let S represent the number of randomly selected adults in a community surveyed to find someone with a certain genetic trait.
The random variable S
follows a geometric distribution with mean 4.66. Which of the following is a correct interpretation of the mean?
A. A value randomly selected from the distribution of S
is expected to be 4.66.
A value randomly selected from the distribution of S is expected to be 4.66.
B. In repeated sampling from the distribution of S
, the average of the values will approach 4.66.
In repeated sampling from the distribution of S, the average of the values will approach 4.66.
C. For a sample of values randomly selected from the distribution of S
, the average of the sample will be 4.66.
For a sample of values randomly selected from the distribution of S, the average of the sample will be 4.66.
D. The probability is 0.66 that a value randomly selected from the distribution of S
will be close to the mean.
The probability is 0.66 that a value randomly selected from the distribution of S will be close to the mean.
E. For a sample of values randomly selected from the distribution of S
, the average of the sample will vary from the population mean by no more than 4.66.
Answer:
In repeated sampling from the distribution of S , the average of the values will approach 4.66.
Step-by-step explanation:
The correct interpretation of the mean is in repeated sampling from the distribution of S, the average of the values will approach 4.66.
The Geometric distribution is a discrete probability distribution that shows the likelihood of the number of failures before the success attained.
Let consider S to be a random variable that represents the selected adults in a community surveyed.
Then
[tex]\mathbf{S \sim G(p) S = 4.66}[/tex]
Therefore, the correct interpretation of the mean is in repeated sampling from the distribution of S, the average of the values will approach 4.66.

Nick and lisa are building a square pond in their backyard. They wish to put a 2 foot wide brick border around the outside. If the total area of the border and the pond is 196 square feet, find the length of the side of the pond.
Answer:
the length of the pond is 10 feet.
Step-by-step explanation:
The computation of the length of the pond side is shown below:
Let us assume the length of the pond side be x feet
Now the one side length with the brick border is x + 4
And, the pond is 196 square feet
Now the equation would be
(x + 4)^2 = 196
(x+4) = 14
x = 10
Therefore, the length of the pond is 10 feet.
The length of each side of the pond is required.
The length of the side of the pond is 10 feet.
AreaLet [tex]x[/tex] be the length of each side of the pool.
If the brick layer is 2 foot wide the size then 2 foot would be added to all the sides of the pool.
The length of each side would be [tex]x+2+2=x+4[/tex]
The area of the pool is [tex]196[/tex] square feet.
So,
[tex](x+4)^2=196\\\Rightarrow x+4=\sqrt{196}\\\Rightarrow x+4=\pm14\\\Rightarrow x=10,-18[/tex]
Since, negative number cannot be the length.
[tex]x=10\ \text{feet}[/tex]

Rachel has $5 in her savings account.
Option 1 will add $35 to her account each week.
Option 2 will double the amount of money in her account at the end of each week.
PART A:
Write a function in terms of x to model each option of saving.
PART B:
Rachel wants to have at least $700 in her account at the end of 8 weeks to go on a class trip. Determine which option will enable her to reach her goal. Justify your answer
Answer:
Step-by-step explanation:
Hello there! this problem will requite us to write 2 equations for both situations described.
firstly, the first equation will look something like this:
[tex]y=35x+5[/tex]
and the second equation will look like this:
y=5(1+100%)^x
If Rachel wants to save up 700 dollars in 8 weeks we can easily solve for which one will get her there by plugging in 700 for y and solving for x.
Solving for x in:
[tex]700=35x+5[/tex]
we find that this option will take a little over 19 weeks
Solving for x in:
700=5(1+100%)^x
we find that this option will take roughly 7.15 weeks
Hope this helps!
Triangle ABC is transformed to obtain triangle A'B'C':
A Coordinate grid (plane, graph, whichever one you like to use) with two triangles on it. Triangle ABC and Triangle A'B'C'. Chart below tells you where the points are placed:
ABC / A= (-12, 12) / B= (-9, 6) / C= (-3, 12)
A'B'C' / A'= (4, -4) / B'= (3, -2) / C'= (1, -4)
Which statement is correct for ▲ABC and ▲A'B'C'?
1. ▲ABC ~ ▲A'B'C' because ▲A'B'C' is obtained by dilating ▲ABC by a scale factor of 1/3 and then rotating it about the origin by 180 degrees.
2. ▲ABC ~ ▲A'B'C' , because ▲A'B'C' is obtained by dilating ▲ABC by a scale factor of 1/4 and then rotating it about the origin by 90 degrees.
3. ▲ABC ~ ▲A'B'C' , because ▲A'B'C' is obtained by dilating ▲ABC by a scale factor of 1/4 and then rotating it about the origin by 180 degrees.
4. ▲ABC ~ ▲A'B'C' , because ▲A'B'C' is obtained by dilating ▲ABC by a scale factor of 1/6 and then rotating it about the origin by 90 degrees.
Answer:
1. ▲ABC ~ ▲A'B'C' because ▲A'B'C' is obtained by dilating ▲ABC by a scale factor of 1/3 and then rotating it about the origin by 180 degrees.
Step-by-step explanation:
given;
ABC / A= (-12, 12) / B= (-9, 6) / C= (-3, 12)
A'B'C' / A'= (4, -4) / B'= (3, -2) / C'= (1, -4)
consider line AC = 9
A'C' = 3
ratio is 9/3, so the factor is 1/3

Answer:
$28.80
Step-by-step explanation:
Multiply $24 by 20% (0.20)
24 x 0.2 = 4.80
So, the tip is $4.80
Add the tip to the price of the tab
24 + 4.8 = 28.8
So the overall price of the restaurant tab is $28.80

3. g + h² = (-7) + (3)² = -7 + 9 = 2
4. g + h = (-7) + (3) = -4
5. h - g= (3) - (-7) = 10
6. g - h = (-7) - (3) = -10

QUESTION #5 - Consumer Math
Answer:
$2.40
Step-by-step explanation:
We know that the sales tax is 8% , we also know that we want to buy two t shirts that cost $15.00 each.
So first, look at what we are purchasing, two t-shirts costing 15.00 dollars each.
Since we are buying two, multiply $15 by 2,
==> $30.00 dollars
And since the sales tax is 8%, to find how much we will pay will mean to multiply the amount by the percent,
30 * 8%
==> $2.40 dollars
You will pay $2.40 dollars in tax
