The perimeter of a rectangular chicken coop is 44 feet. The width is w feet and the length is w + 4 feet. What are the length and width of the coop?

Answers

Answer:

w = 9 ft

l = 13 ft

Step-by-step explanation:

2w + 2(w+4) = 44

simplify:

4w + 8 = 44

4w = 36

w = 9 ft

l = 13 ft

The Arc Electronic Company had an income of 7676 million dollars last year. Suppose the mean income of firms in the same industry as Arc for a year is 9090 million dollars with a standard deviation of 77 million dollars. If incomes for this industry are distributed normally, what is the probability that a randomly selected firm will earn more than Arc did last year

Answers

Answer:

0.9772 = 97.72% probability that a randomly selected firm will earn more than Arc did last year

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Suppose the mean income of firms in the same industry as Arc for a year is 90 million dollars with a standard deviation of 7 million dollars.

This means that [tex]\mu = 90, \sigma = 7[/tex]

What is the probability that a randomly selected firm will earn more than Arc did last year?

Arc earned 76 million, so this is 1 subtracted by the pvalue of Z when X = 76.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{76 - 90}{7}[/tex]

[tex]Z = -2[/tex]

[tex]Z = -2[/tex] has a pvalue of 0.0228

1 - 0.0228 = 0.9772

0.9772 = 97.72% probability that a randomly selected firm will earn more than Arc did last year

Find the probability that when a couple has five children, at least one of them is a boy. (assume that boys and girls are equally likely.)​

Answers

Answer:

The easiest way to figure this is to find P(no girls in 5 births) = (1/2)^5 = 1/32 -------------- The P(at least one girl in 5 births) = 1 - 1/32 = 31/32

The probability that when they have five children, at least one of them is a boy is 31/32

Probability is the likelihood or chance that an event will occur.

Probability = Expected outcome/Total outcome:

The probability that a couple will have a boy or girl among the five children = 1/2

If they gave birth to 5 children:

The probability that when they have five children, at least one of them is a boy = 1 - (1/2)^n where:

n is the total number of children

The probability that when they have five children, at least one of them is a boy = 1 - (1/2)ⁿ

The probability that when they have five children, at least one of them is a boy = 1 - (1/2)⁵

The probability that when they have five children, at least one of them is a boy = 1- 1/32 = 31/32

Hence the probability that when they have five children, at least one of them is a boy is 31/32

a ramp was constructed to load a truck. if the ramp is 10 ft long and the horizontal distance from the bottom of the ramp to the is 8 ft, what is the height from the ground to the top of the ramp?

Answers

You can use the Pythagorean theorem to do this. a^2 + b^2 = c^2.
a=8 ft
b=unknown
c=10ft
Square 10, to get 10,000
Square 8 to get 64
Subtract 64 from both sides
Then square root both sides to get x by itself. X = 99.7 ft
If we assume that the angle created by horizontal distance and the height of the ramp is 90 degrees, we could use Pythagorean theorem c^2=a^2+b^2
c=10ft
b=8ft
a=? aka height

10^2=a^2+8^2
100=a^2+64
a^2=100-64
a^2=36
a= √36
a=6 ft
Height from the ground to the top of the ramp is 6ft.
