A fast-food restaurant has a cost production of C(x) = 7x + 117 and a revenue
function of R(x) = 28x, where I represents the number of milkshakes they
make. When does the company start to turn a profit?

Answers

Answer 1

Answer:

6

Step-by-step explanation:

Profit is revenue minus cost.

P(x) = R(x) − C(x)

P(x) = 28x − (7x + 117)

P(x) = 21x − 117

When the profit is 0, the value of x is:

0 = 21x − 117

21x = 117

x = 5.6

Rounding up to the nearest integer, the company starts to turn a profit at 6 milkshakes.

A large container for water weighs 21 pounds. If a gallon of water weighs 8.34 pounds, what is an equation that relates the weight of the
water and the container, W. in pounds and the amount of water, A, in gallons? (1 point)
W

Answers

Answer:

The equation that relates the weight of the water and the container in pounds and the amount of water in gallons is [tex]A = \frac{W}{8.34}[/tex].

Step-by-step explanation:

From Physics we understand that conversions are represented by the following linear equation:

[tex]u' = r\cdot u[/tex] (1)

Where:

[tex]u[/tex] - Original value, measured in original unit. (pounds)

[tex]r[/tex] - Conversion value, measured in final unit per original unit. (gallons per pound)

[tex]u'[/tex] - Final value, measured in final unit. (gallons)

If we know that [tex]u' = A[/tex], [tex]u = W[/tex] and [tex]r = \frac{1}{8.34} \,\frac{gal}{lbm}[/tex], then the equation is:

[tex]A = \frac{W}{8.34}[/tex]

The equation that relates the weight of the water and the container in pounds and the amount of water in gallons is [tex]A = \frac{W}{8.34}[/tex].

Answers

Answer:

y + 2 = -4/5 (x - 3)

Step-by-step explanation:

y - y1 = m (x - x1). Put in your points for y1 and x1, and always remember to flip your signs.

unfortunately, I don't know why that isn't one of your answers, so sticking with the positive 2 I would choose y+2=- (- 3) if I were you. Looks like the -4/5 disappeared somehow?

For this question the average height of adult women is 63.7” with a sigma of 2.9”.  The US Navy requires that fighter pilots have heights of between 62 and 78 inches.  Find the approximate percentage or women who qualify to be fighter pilots.  HINT:  Drawing a distribution curve may help.
​

Answers

Answer:

72%

Step-by-step explanation:

For this question the average height of adult women is 63.7” with a σ of 2.9”.  The US Navy requires that fighter pilots have heights of between 62 and 78 inches.  Find the approximate percentage or women who qualify to be fighter pilots.  HINT:  Drawing a distribution curve may help.

Find the z-scores.

z = (x − μ) / σ

z₁ = (62 − 63.7) / 2.9

z₁ = -0.586

z₂ = (78 − 63.7) / 2.9

z₂ = 4.93

Use a chart or calculator to find the probability.

P(-0.586 < Z < 4.93) = P(Z < 4.93) − P(Z < -0.586)

P(-0.586 < Z < 4.93) = 1.000 − 0.279

P(-0.586 < Z < 4.93) = 0.721

Approximately 72% of women will qualify.

If the Navy changes its height requirement to include all but the shortest and tallest 3% of the female population, what would the new height requirements for women be? HINT:  Drawing a distribution curve may help. Also, rounding is suggested.

In this case, we work in reverse.  Use a chart or calculator to find the z-score for each probability.

P(Z < z₁) = 0.03

z₁ = -1.881

P(Z > z₂) = 0.03

P(Z < z₂) = 0.97

z₂ = 1.881

Now find the heights associated with those z-scores.

z = (x − μ) / σ

-1.881 = (x₁ − 63.7) / 2.9

x₁ = 58.2

1.881 = (x₂ − 63.7) / 2.9

x₂ = 69.2

The new height requirement is between 58.2" and 69.2".
