b) The university gym opens at 9 am on Saturday mornings. One Saturday morning at 8:55 am there are 15 students outside the gym waiting for it to open. Should you use the same approach from part (a) to calculate the expected number of smokers among these 15 students
Answers
Answer:
The complete question is:
At a university, 13% of students smoke.
a) Calculate the expected number of smokers in a random sample of 100 students from this university:
b) The university gym opens at 9 am on Saturday mornings. One Saturday morning at 8:55 am there are 27 students outside the gym waiting for it to open. Should you use the same approach from part (a) to calculate the expected number of smokers among these 27 students?
Part a is easy, because is a random sample, we can expect that just 13% of these 100 students to be smokers, and 13% of 100 is 13, so we can expect 13 of those 100 students to be smokers.
b) This time we do not have a random sample, our sample is a sample of 15 students who go to the gym in the early morning, so our sample is biased. (And we do not know if this bias is related to smoking or not, and how that relationship is), so we can't use the same approach that we used in the previous part.

What is the equation of the described circle?
A) (x - 2)^2 + (y + 3)^2 = 58
B) (x - 2)^2 + (y + 3)^2 = 68
C) (x + 2)^2 + (y - 3)^2 = 58
D) (x + 2)^2 + (y - 3)^2 = 68
If the circle passes through the point (6,5), what is the equation of the new circle with the same center?
A) (x + 2)^2 + (y - 3)^2 = 80
B) (x + 2)^2 + (y - 3)^2 = 90
C) (x - 2)^2 + (y + 3)^2 = 80
D) (x - 2)^2 + (y + 3)^2 = 90
Answers
Answer: Part A: A. Part B: C
Step-by-step explanation:
Substitute the number into the equation of circle: (x-h)^2 + (y-k)^2=r^2
h and k are 2, -3 so you will need to change their signs.
The final thing you will do is to find the distance of center to point. Using distance formula and you will able to find the radius. Square your radius then the result will be there

Answer:
hope it helps!
Step-by-step explanation:
Perimeter includes three sides of rectangle:
15m + 12m + 15m
Plus half of circle with diameter 12m
Circumference = diameter * PI
Circumference = 37.68m.
1/2 circumference = 18.84m
Total perimeter is 15m+12m+15m+18.84m
60.84m

The length of a rectangle is 3 inches longer than it is wide. If the area is 180 square inches, what are the
dimensions of the rectangle?
Answers
Answer:
Width=12 inches
Length=15 inches
Step-by-step explanation:
Let's say the width is x.
Then, the length is x+3.
The area of a rectangle is the length times width, so
x(x+3)=180
x^2+3x=180
x^2+3x-180=0
After using the quadratic formula, x comes out to be 12 or -15.
x cannot be -15 because you can't have negative distance, so we are left with x=12.
The width is 12 inches and the length is 12+3=15 inches.
Check: 12*15=180
Answer:
The width is 12 and the length is 15.
Step-by-step explanation:
You set the equation as x is equal to the width and since the lenght is 3 units longer than the width, it can be seen as "x + 3"
[tex]Area=(Length)(Width)[/tex]
180= x × (x + 3)
Then from there you just solve for x.

Answer:
2 .The slope of Function A is less than the slope of Function B
A graph of Function A shows it has a y-intercept of 4, the same as that of Function B. (Statements 3 and 4 are not correct.)
The slope of Function A is 2, which is less than the slope of 3 that Function B has. (Statement 2 is correct; statement 1 is not.)
