Resiprocal of (-3/7)^2!

USPshnik [31]

Answer:

$\frac{49}{9}$

Step-by-step explanation:

Given

$(\frac{-3}{7})^{2!}$

Required

Determine the reciprocal

If a number is x, the reciprocal is: 1/x

So, the reciprocal of $(\frac{-3}{7})^{2!}$ is:

$\frac{1}{(\frac{-3}{7})^{2!}}$

$2! = 2*1 =2$

So, we have:

$\frac{1}{(\frac{-3}{7})^{2}}$

$\frac{1}{(\frac{-3^{2}}{7^{2}})}$

Evaluate all exponents

$\frac{1}{(\frac{9}{49})}$

Take inverse of 9/49

$\frac{49}{9}$

Hence, the reciprocal of $(\frac{-3}{7})^{2!}$ is $\frac{49}{9}$

Consider a disease whose presence can be identified by carrying out a blood test. Let p denote the probability that a randomly s

barxatty [35]

Answer:

0 tests

Yes, this procedure is better on the average than testing everyone, it makes it less cumbersome.

Step-by-step explanation:

Given the information:

Let P be the probability that a randomly selected individual has the disease = 0.1. N individuals are randomly selected, thereafter, blood samples of each person would be tested after combining all specimens. Should in case one person has the disease then it yields a positive result and test should be set for each person.

Let Y be number tests

For n = 3 there are two possibilities. If no one has the disease then the value is 1 otherwise the value is 4, here P = 0.1

Therefore, for Y = 1

P(Y-1) = P(no one has disease)

= 0.9³

= 0.729

If Y = 4

P(Y-4) = 1-P(y = 1)

= 1 - 0.729 = 0.271

The expected number of tests using this formular gives

E(Y) = 1×0.729 + 4×0.271

E(Y) = 0
