 Jeremy and Randell are brothers and each are trying to raise money for summer camp.
To help Jeremy raise money, his parents told him he could wash each of their cars once a week for $20.00 each. He has already earned $640.00. The football camp that he wants to attend costs $1,469.00.
To help Randell raise money, his parents told him he could mow the grass for them and both sets of grandparents once every 2 weeks and earn $28.00 for each lawn he mows. He has already earned $728.00. The lacrosse camp that he wants to attend costs $1,701.00.
If Jeremy and Randell each earn enough money to attend the camps of their choice, then from this point on (randell) needs to complete (idk what would got here) more chores than(jeremy)

is it asking you to fill in the blanks with their names if so i think it would be this.

If the function graphed is f(x), find f(1).
Crazy boy [7]
Locate 1 on the x axis. This is the horizontal number line. 

Draw a vertical line through 1 on the x axis. Extend this vertical line as far up and down as you can.

Notice how the vertical line crosses the blue curve. Mark this point. Then draw a horizontal line from this point to the y axis. The horizontal line will touch -4 on the y axis. So that means the point (1,-4) is on the curve.

If the input it is x = 1, then the output is y = -4

So that's why the answer is choice A

Complete the point-slope equation of the line through (1,3) (5,1) y-3=?
MaRussiya [10]

Answer:

\huge\boxed{y-3=-\frac{1}{2}(x-1)}

Step-by-step explanation:

Point-slope is:

y-y_1=m(x-x_1)

m-\text{This represents the slope.}\\\\(x_1,y_1)-\text{This represents the point used in the equation.}

<h2>Our goal: </h2>

We have to complete the point-slope equation of the line through (1,3) (5,1).

--------------------------------------------------------

We have a incomplete equation of the line.

y-3=m(x-x_1)

We need to find the <u>slope</u> of the line, and the <u>value</u> of  x_1.

--------------------------------------------------------

<h3>Finding 'x1':</h3>

It seems that the value of 3 was used to be y_1. This means that the point (1,3) was used for the equation. This means that x_1 would have to be 1.

<h3>Finding Slope:</h3>

Slope is rise over run.

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

We are given the points (1,3) and (5,1).

m=\frac{1-3}{5-1}=\frac{-2}{4}=\frac{-1}{2}=\boxed{-\frac{1}{2}}

The slope is one-half.

--------------------------------------------------------

We now have enough information to complete the point-slope equation.

{\left \{ {{x_1=1} \atop {m=-\frac{1}{2} }} \right.}\\\\y-3=m(x-x_1)\rightarrow\boxed{y-3=-\frac{1}{2}(x-1)}

Our final equation is:

y-3=-\frac{1}{2}(x-1)

Artist 52 [7]

Answer:

8 and 2.529

Step-by-step explanation:

The computation of the mean and the standard deviation is shown below:

Given that

Total number of questions is n =  40

The Probability of correct answer is p =  \frac{1}{5}

So, the probability of the wrong answer is q =  1 - \frac {1}{5} = \frac{4}{5}

Moreover, this is the binomial distribution

Based on the above information

The mean is

= n \times p

= 40\times \frac{1}{5}

= 8

Now the variance is

= 40\times \frac{1}{5} \times \frac{4}{5}

= \frac{32}{5}

So, the standard deviation is

= \sqrt{\frac{32}{5} }

= 2.529

hence, the mean and the standard deviation is 8 and 2.529 respectively
