Answer: 24.9793

Step-by-step explanation:

Given : The director randomly selects 64 different 24-hour periods and determines the number of admissions for each.

For this sample, he calculated a mean $\overlien{x}=396$ and a standard deviation of 100.

The 95% confidence interval results in an interval of $396 \pm 24.9793$

We know that the confidence interval for population mean is given by :_

$\overlien{x}\pm E$ , where E is the margin of error.

(a-12)x=a+8 if this equation has no solution and a is a constant. what is the value of a

lbvjy [14]

Answer:

a=12

Step-by-step explanation:

If you solve for x, you divide by (a-12) to isolate x on the left side:

x = (a+8)/(a-12)

If the numerator is 0 you will be dividing by zero, which invalidates the solution. This will happen for a=12.
