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
Just use the orders of operation, or PEMDAS
Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction
63 + (15 - 6) * 14 + 2
Parenthesis first!
63 + 9 * 14 + 2
No exponents, let’s multiply!
63 + 126 + 2
No division or subtraction, let’s add the rest

Answer: 5 = 5 or true its an equal equation.
Step-by-step explanation:
The equation would look like this: 2 + 3 = 10 divided by 2. This equation is extremely easy it turns out to be 5 = 5 because 2 + 3 = 5 and 10 divided by 2 is 5 so your final answer is 5 = 5 or if its a true or false question, the answer is true it is an equal equation.

Answer:
Step-by-step explanation:
If you have not notised, is therefore you have this:
I am joyous to assist you at any time.
Simplifying
2(3(4 + p) + p) + p
2((4 * 3 + p * 3) + p) + p
2((12 + 3p) + p) + p
Combine like terms: 3p + p = 4p
2(12 + 4p) + p
(12 * 2 + 4p * 2) + p
(24 + 8p) + p
Combine like terms: 8p + p = 9p
24 + 9p
