SA = Base Area • 2 + base perimeter • distance

SA = 1/2(12•8)+(12+10+10)•10
1/2(96)+(32•10)
48+320
SA= 368

Annual starting salaries for college graduates with degrees in business administration are generally expected to be between 2000

ehidna [41]

Answer:

The planning value for the population standard deviation is of 4330.

Step-by-step explanation:

Uniform probability distribution:

The uniform probability distribution has two bounds, a and b. The standard deviation is given by:

$S = \sqrt{\frac{(b-a)^2}{12}}$

Annual starting salaries for college graduates with degrees in business administration are generally expected to be between 20000 and 35000.

Uniform in this interval, so $a = 20000, b = 35000$

What is the planning value for the population standard deviation?

$S = \sqrt{\frac{(35000 - 20000)^2}{12}} = 4330$

The planning value for the population standard deviation is of 4330.

Use the Discriminant to describe the roots of each equation. Then select the best description.

TiliK225 [7]

The discriminant is the part under the sqrt in the quadratic formula
for ax²+bx+c, the discriminant is b²-4ac

if the discriminant is
less than 0, then there are non-real roots
equal to 0, then there is a double root
greater than 0, then there are 2 real roots (may be rational or irrational)

so

1x²-5x+7

b²-4ac=(-5)²-4(1)(7)=25-28=-3
less than 0 so it is non real roots

answer is D

How do you solve for x?

EastWind [94]

To find the answer for x, you have to use the pythagoryen theorem. The line AC is 16 inches, but the little segment of the triangle is 4 inches. So first, you have to use the pythaoryen theorem and get this equation: CB plus AB=16 inches. Once you find CB, use it again to find the value of DB. DB plus DC equals CB. Then DB = X.
