Answer:

Step-by-step explanation:

Let x represents the amount that the customer pays per hour

for renting the vacuum cleaner before returning it.

Let y represent the flat rate that the store charges a customer for renting the vacuum cleaner.

Let F represent the amount that the store charges a customer for renting the vacuum cleaner for x hours.

A linear function F for the total retail cost of a vacuum cleaner would be

F(x) = x + y

If the customer rents it for n hours, the total amount becomes

F(x) = nx + y

Consider the equation 3p – 7 + p = 13. What is the resulting equation after the first step in the solution?

gulaghasi [49]

3p-7+p=13 ok so you will want to add 3p to 1p if there's only a variable then there a invisible 1 in front of it so you'll add 3 to 1 wich is 4 so now your problem Is now 4p-7=13 you then make the negative 7 to a positive 7 so now your going to add 13+7 wich equals 20 now you divide 20 by 4 wich gives you 5

The triangle shown below has an area of 121212 units^2 <br> 2<br> squared.<br> Find xxx.

dalvyx [7]

Answer:

Step-by-step explanation:

Let's set up an equation using the formula for the area of a triangle.

Hint #22 / 3

\begin{aligned} \text{Area of a triangle} &= \dfrac12 \cdot \text{base} \cdot \text{height}\\\\ 12&= \dfrac12 \cdot 6 \cdot x \\\\ 12&= 3x \\\\ \dfrac{12}{\blueD{3}}&= \dfrac{3x}{\blueD{3}} ~~~~~~~\text{divide both sides by } {\blueD{ 3}}\\\\ \dfrac{12}{\blueD{3}}&= \dfrac{\cancel{3}x}{\blueD{\cancel{3}}}\\\\ x &=\dfrac{12}{\blueD{3}}\\\\ x &=4\end{aligned}

Area of a triangle

⋅base⋅height

⋅6⋅x

=3x

divide both sides by 3

A randomly generated list of number from 0 to 7 is being used to simulate an event, with the numbers 0 and 1 representing a succ

Nitella [24]

Probability to get a success is 0 AND one

1) P(getting 0) = 1/8 ( from 0 to 7 = 8 numbers)

2) P(getting 1) = 1/8

P(1 and 0) = 1/8 x 1/8 = 1/64 =0.0156 = 1.56%

Suppose students' ages follow a skewed right distribution with a mean of 24 years old and a standard deviation of 3 years. If we

natta225 [31]

Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

Mean of students' age = 24 years

Standard deviation of students' age = 3 years

Sample size = number of students = 350

So, according to options,

a. The shape of the sampling distribution is approximately normal.

It is true as n >30, we will use normal.

b. The mean of the sampling distribution is approximately 24-years old.

It is true as it is given.

c. The standard deviation of the sampling distribution is equal to 5 years.

It is not true as it is given 3 years.

Hence, Option 'c' is correct.
