4 0

Answer:

x = 6

Step-by-step explanation:

Equation

(1 + 5 + 10 + x)/4 = 5.5 Multiply both sides by 4

Solution

4* (1 + 5 + 10 + x ) /4 = 5.5 * 4

16 + x = 22 Subtract 16 from both sides

16-16+x = 22- 16

x = 6

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
