Answer:
Hello!
First you have to find the rate between the amount of students surveyed by the total amount
You do this by dividing the total amount of students by the amount of students surveyed
1500 / 50 = 30
We multiply the amount of students that have a pet by this number
32 * 30 = 960
The answer is B)960
Hope this helps!

Because of isosceles triangle, AB = CB.
Because of the median, AD = CD.
Because of congruence of segments being reflexive, BD = BD.
By SSS, the triangles BAD and BCD are congruent.
Answer: B.
Answer:
Since 2.1387 is Greater Than 1.645;
we reject null hypothesis; we conclude that, the nickname is justified based on the data.
Step-by-step explanation:
Given the data in the question;
Null hypothesis H₀ : p = 0.262
Alternative Hypothesis H₁ : p > 0.262.
p" = 0.357
q = 1 - p = 1 - 0.262 = 0.738
n = 98
so;
z = (p" - p) / √(pq/n)
we substitute
z = (0.357 - 0.262) / √((0.262×0.738) / 98)
z = 0.095 / 0.04441869
z = 2.1387
at 5% CONFIDENCE INTERVAL
z-critical = 1.645
Since 2.1387 is Greater Than 1.645;
we reject null hypothesis; we conclude that, the nickname is justified based on the data.

First, since Kim has already read 2 pages you subtract 44-2. Now you only have to divide 42 by 20 which is 2.1 hours. 2.1 hours is the equivalent of 2 hours and 6 minutes.
