Answer:

Step-by-step explanation:

n(AUB)=n(A)+n(B)-n(A∩B)

greatest intersection of (A∩B)=65

n(A∪B)=80+65-65=80

so least value of n(A∪B)=80

What is the value of x? 3x−8=(8x+4 ----- 2

stepladder [879]

3x-8 = 8x+4

subtract 3x from each side

-8 = 5x+4

subtract 4 from each side

-12 = 5x

divide -12 by 5 to get x

x = -12/5 = -2.4

Answer: second step.

Step-by-step explanation:

you then have to distribute the answer not subtract 9 1/4 from 1.5

you have to do the parenthesis next

4.5/0.5=45/5=9

Svetlanka [38]

Answer:

z=3.8196

Step-by-step explanation:

-We notice that this is a normal distribution problem.

-Given the mean is $8500, standard deviation is $1200 , and n=350, the critical z-value using alpha=0.05 is calculated as:

$z=\frac{x-\mu_o}{\sigma/\sqrt{n}}\\\\=\frac{8745-8500}{1200\sqrt{350}}\\\\\\=3.8196$

Hence, the test statitic is z=3.8196
