52 I think , because 6 1/2 x 8 is 52
Where are the numbers so that people can help you
Answer:
12. (4, 7)
13. (5, -1)
Step-by-step explanation:
Rewrite in vertex form and use this form to find the vertex (h, k).
Answer:
(x +9) ^2 + (y +7)^2 = 289
Step-by-step explanation:
We know the equation of a circle can be written as
(x-h) ^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius
We are given the diameter so we can find the radius
r = d/2 = 34/2 = 17
(x- -9) ^2 + (y- -7)^2 = 17^2
(x +9) ^2 + (y +7)^2 = 17^2
(x +9) ^2 + (y +7)^2 = 289
Answer:
12
Step-by-step explanation:
The expected value is 
, where n=148 is the sample size and 
.
We calculate the z-score of 37.5 using the formula:
From the standard normal distribution table, the area to the left of 1.43 is 0.9236.
.
The expected number of people in the sample with body temperatures above 37.5 degrees is 
We don't have a fractional human being, so the rule of thumb is to round up.
