Answer: 140 m3

Step-by-step explanation:

Multiply the area of the trapezoid face by the length .

Since the area is 20, you multiply it by 7 to get 140

Answer:

140 m^3

Step-by-step explanation:

This is a prism with a trapezoid base.

The volume if a prism is

V = (area of base) * height

The base is the trapezoid in the front face. The height is the distance between bases which is 7 m.

area of trapezoid = (b1 + b2)h/2

In the area of the trapezoid, h is the height of the trapezoid which is the distance between parallel bases. It is 4 m in this case.

V = (area of base) * (height of trapezoid)

V = (8 m + 2 m)(4 m)/2 * 7 m

V = 20 m^2 * 7 m^2

V = 140 m^3

Suppose that two electronic components in the guidance system for a missile operate independently and that each has a length of
lord [1]

Answer:

The probability density function for the average length of life of the two components is f(x) = 0.5e^{-0.5x}

Step-by-step explanation:

Exponential distribution:

The exponential probability distribution, with mean m, is described by the following probability density:

f(x) = \mu e^{-\mu x}

In which \mu = \frac{1}{m} is the decay parameter.

Each missile has a length of life governed by the exponential distribution with mean 1 (with measurements in hundreds of hours). Find the probability density function for the average length of life of the two components.

2, each with mean 1 means that m = 2*1 = 2, \mu = \frac{1}{2} = 0.5

So the probability density function is:

f(x) = 0.5e^{-0.5x}

Find a​ point-slope1/5 form for the line with slope
lisabon 2012 [21]

Answer:

y+9=1/5(x+3)

Step-by-step explanation:

Point slope formula: y-y1=m(x-x1)

slope=m

m=1/5

-3=x1 -9=y1

y-(-9) =1/5(x-(-3))

simplify...

y+9=1/5(x+3)
