Answer:

 1)   Volume of prism = \frac{105}{8}ft^3=13.125ft^3

 2) Option B is the correct answer.

Explanation:

1) Volume of a prism is given by the expression, Volume V = Base area of prism x Height of prism.

 Base area = 3\frac{1}{2} *2\frac{1}{2}=\frac{3*2+1}{2} *\frac{2*2+1}{2} =\frac{7}{2} *\frac{5}{2}=\frac{35}{4} ft^2

Volume = \frac{35}{4}*1\frac{1}{2} =\frac{35}{4}*\frac{1*2+1}{2}=\frac{35}{4}*\frac{3}{2}=\frac{105}{8}ft^3

 Volume of prism = \frac{105}{8}ft^3=13.125ft^3

2) Volume of a prism is given by the expression, Volume V = Base area of prism x Height of prism.

 Base area = 4\frac{1}{4} *3in^2

 Volume = 4\frac{1}{4} *3*1\frac{1}{4}in^3

 Option B is the correct answer.

antoniya [11.8K]

Answer:

A. 2.5 standard deviations below the average salary.

Step-by-step explanation:

In a normally distributed sample, the z-score measure how many standard deviations a measure is above or below the mean.

If the zscore is positive, the measure is above the mean.

If it is negative, the measure is below the mean.

A quality control specialist calculated the​z-score associated with his own salary and found it was minus2.50. What is his​ salary?

This means that his salary is 2.5 standard deviations below the mean, that is the average salary.

The correct answer is A.

Nuetrik [128]
So 9x<18 can be factored out into 
9(x)<9(2)
you can divide both sides by 9
x<2 

so the solution is any number more than 2, but not 2
