A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 108.7-cm and a standard dev
Luden [163]

Let x be the lengths of the steel rods and X ~ N (108.7, 0.6)

To get the probability of less than 109.1 cm, the solution is computed by:


z (109.1) = (X-mean)/standard dev

= 109.1 – 108/ 0.6

= 1.1/0.6

=1.83333, look this up in the z table.


P(x < 109.1) = P(z < 1.8333) = 0.97 or 97%

The width of a rectangular garden is 8 feet longer than 4 times its length. If the garden's perimeter is116 feet, what are the d
Travka [436]

SOLUTION:

Step 1:

The length of a rectangular garden is 8 feet longer than its width.

If the garden's perimeter is 184 feet.

What is the area of the garden in square feet?

Step 2:

L = length

W = width

L = W+8

P = perimeter

P = 2(L+W)

P =184 (given)

Substitute L=W+8 in the perimeter equation

2( (W+8) + W ) = 184

(W+8) +W = 92

2W + 8 = 92

2W = 84

W = 42 ft ( Width = 8 feet )

L = W+8

L = 42+8

L = 50 ft ( Length = 50 feet )

Always check your work.

In this case, check the perimeter.

2(L+W) = ?

2(50+42) = 184 feet.

CONCLUSION:

Then, the question says:

It asks for the area in square feet.

A = Area

A = L*W

A = 50 ft * 42 ft

A = 2100 sq ft.
