Answer:
The measure of the missing side length = 45
Step-by-step explanation:
Pythagorean Theorem states: A² + B² = C²
28² + B² = 53²
784 + B² = 2809
B² = 2809 - 784
B² = 2025
B =
B = 45
Therefore the measure of the missing side length = 45
Hope this helps!
Answer:
The expected number of tests necessary for the entire group of 304 people is 180.0325
Step-by-step explanation:
Probability of person being positive = p = 0.04
Probability of person being negative = q = 1-0.04=0.96
Number of people in each group = 19
We will use binomial over here
Probability of no test positive :
P( at least one tests positive) = 1-P( no one tests positive)= 1-0.460419201958= 0.539580798042
Expected number of tests for each group = 1(0.460419201958)+20(0.539580798042) = 11.2520351628
Number of groups =
Expected number of tests necessary for the entire group of 304 people:
=
=
=180.0325
Hence The expected number of tests necessary for the entire group of 304 people is 180.0325
