Evaluate each value expression for the given value of x: 11 + x, x=12

ratelena [41]

Answer:

The value of 11+x at x=12 will be 23.

Step-by-step explanation:

Given the expression

$11 + x$

As we have to evaluate the expression at x=12

so substitute the value x=12 in the expression

$11 + x$

$=11+12$

$=23$

Therefore, the value of 11+x at x=12 will be 23.

The workers' union at a particular university is quite strong. About 96% of all workers employed by the university belong to the

vredina [299]

Answer: 0.1699

Step-by-step explanation:

Given: The proportion of all workers employed by the university belong to the workers' union = 0.96

Sample size : n= 5

Binomial probability distribution formula :

$P(X=x)= \ ^nC_xp^x(1-p)^x$

The probability that exactly 4 of the workers interviewed are union members :-

$P(X=4)=^5C_4(0.96)^4(1-0.96)^1\\\\=(5)(0.96)^4(0.04)\\\\=(5)(0.84934656)(0.04)\\\\=0.169869312\approx0.1699$

Required probability = 0.1699
