Answer:
5(9+x)
Step-by-step explanation:
5 x 9 = 45
then if do 5 times x it would look like 5x
Circumference = 2 x Pi x R
if we use 3.14 as pi, you would do 2 x 3.14 x 4, which would equal 25.12, i’m not sure if it was meant to be rounded to 25, but none of the multiple choice answers would be correct
Answer:
2/3
Step-by-step explanation:
A = Student studying Math
B = Student studying Science
P(B|A) = P(A and B) ÷ P(A).
P(B|A) means the probability of event B given event A.
Given :
P(A and B) = 0.40.
Also P(A) = 0.60.
P(B|A) = 0.40 ÷ 0.60 = 2 ÷ 3.
So, the answer is 2/3.
Im pretty sure it’s All students in each grade because it says she wants the sample from the ^entire^school
