A company manufactures and sells shirts. The daily profit the company makes depends on how many shirts they sell. The profit, in

dollars, when the company sells x x shirts can be found using the function f ( x ) = 7 x − 40. f(x)=7x−40. Find and interpret the given function values and determine an appropriate domain for the function. f ( − 10 ) = f(−10)= , meaning if the company sells shirts, they would make a profit of dollars. This interpretation in the context of the problem. f ( 10 ) = f(10)= , meaning if the company sells shirts, they would make a profit of dollars. This interpretation in the context of the problem. f ( 9.5 ) = f(9.5)= , meaning if the company sells shirts, they would make a profit of dollars. This interpretation in the context of the problem. Based on the observations above, it is clear that an appropriate domain for the function is .

A gondola (cable car) at a ski area holds 50 people. Its maximum safe load is 10000 pounds. A population of skiers has a distrib
fenix001 [56]

Answer:   0.03855

Step-by-step explanation:

Given :A population of skiers has a distribution of weights with mean 190 pounds and standard deviation 40 pounds.

Its maximum safe load is 10000 pounds.

Let X denotes the weight of 50 people.

As per given ,

Population mean weight of 50 people = \mu=50\times190=9500\text{ pounds}

Standard deviation of 50 people =\sigma=40\sqrt{50}=40(7.07106781187)=282.84

Then , the probability its maximum safe load will be exceeded =

P(X>10000)=P(\dfrac{X-\mu}{\sigma}>\dfrac{10000-9500}{282.84})\\\\=P(z>1.7671-8)\\\\=1-P(z\leq1.7678)\ \ \ \ [\because\ P(Z>z)=P(Z\leq z)]\\\\=1-0.96145\ \ \ [\text{ By p-value of table}]\\\\=0.03855

Thus , the probability its maximum safe load will be exceeded = 0.03855

10 POINTS!! PLEASE HELP
BigorU [14]

Answer:

Option 2: 2x + 2 = 72

Step-by-step explanation:

First odd: x

Next odd: x + 2

x + (x + 2) = 72

2x + 2 = 72

Because the difference between two consecutive odd numbers is 2.

e.g 3 and 5

The function that passes through thepoints (24, 28) and (8,8)Is?
icang [17]

The slope of the line that passes through the points (x1, y1) and (x2,y2) is computed as follows:

m=\frac{y_2-y_1}{x_2-x_1}

In this case, the points are (24, 28) and (8,8), then its slope is:

m=\frac{8-28}{8-24}=\frac{-20}{-16}=\frac{5}{4}

The slope-intercept form of a line is:

y = mx + b

where m is the slope and b is the y-intercept

Substituting into the general equation with m = 5/4 and the point (24, 28) we get:

\begin{gathered} 28=\frac{5}{4}\cdot24+b \\ 28=30+b \\ 28-30=b \\ -2=b \end{gathered}

Finally, the equation is

y = 5/4x - 2

Y varies inversely with x, if y = -12 when x = 8 what is x when y = -9
Minchanka [31]

Answer:

either 5 or 11

Step-by-step explanation:

(8, -12)

(5, -9) or (11, -9)

If y varies consistently with x then it would copy what happens, in a manner of speaking.

In this case, y increases by three, x would either add 3 or subtract 3

I am not completely sure on this.
