Answer:

773.8 inch²

Step-by-step explanation:

Find the surface area at first

the top and bottom = 6²π = 36π  

around is circumference x by height = 12π x 15 = 180 π

multiply these by 3/4

top = 27π

bottom = 27π

around = 135π

add the two rectangles  = 180 inch²

Total = 773.8

A drug company conducts trials of a new vaccine for a rare but usually fatal disease. The company creates a
GalinKa [24]

Answer:

What can be said about the model are;

1) The company predicts 4 failures before success

2) Each trial is independent

3) The probability is the same for each trial

4) Success is defined as preventing the disease

Step-by-step explanation:

The probability of success for the vaccine, p = 0.2

Therefore, the probability that the vaccine is effective and prevents the disease = 0.2

A geometric distribution probability of success is given by the following formula;

P(X = x) = p × q⁽ˣ⁻¹⁾

The expected value, E(Y) = 1/p

The number of failures before success, E(Y) = (1 - p)/p = (1 - 0.2)/0.2 = 4

Where;

q = The probability of a trial failing = 1 - p = 1 - 0.2 = 0.8

q = 1 - p

∴ The e

The geometric model criteria are;

a) Each trial can only have one of two outcomes success or failure

b) The probability of success for each trial is fixed

c) The geometric distribution is concerned with finding how many trials are required to get one success

d) The trials are independent

Therefore, we have;

The number of failures the company predicts before a success = 4 failures

2) The trials are independent

3) Each trial has an equal probability

4) Success is defined by the effectiveness of the vaccine in the prevention of the disease

How many different 4 digit numbers are there that are only made up of even digits
malfutka [58]
In a four-digit number, the first digit cannot be 0, so there are only 4 even numbers available. For the second, third, and fourth digits, there are 5 available numbers. Thus, the number of 4-digit numbers containing only even digits is 4 x 5 x 5 x 5 = 500 numbers.

8u/u^2-18u+81 subtract 72/u^2-18u+81
Karo-lina-s [1.5K]
Your question is:
\frac{8u}{u^2-18u+81} -\frac{72}{u^2-18u+81}
Then, the above formula equate:

\frac{8u-72}{u^2-18u+81}
Factor out 8 from the numerator we get:
\frac{u-9}{u^2-18u+81}
Factorization of the denominator:
\frac{u-9}{(u-9)^2}
Simplifying the numerator and the denominator by (u-9) we get:
\frac{1}{(u-9)}
