Answer:
Desmond has a debt of $98.
Step-by-step explanation:
We are given that Desmond has a monthly Netflix subscription that charges him $14. Since it is a monthly subscription, it is a recurring charge.
We are also given that he does not make payments for 7 months. This means that the subscription is recurring for seven months.
Therefore, if he is charged $14 monthly and is charged that for 7 months, we can say that he is charged $14 seven times.
Therefore, we can create an equation that solved how much his debt would be based on this information.
[tex]\displaystyle14(7) = c\\\\14\times7=98\\\\c = 98[/tex]
Therefore, Desmond has a debt of $98.
A track team contains sprinters numbered 1,2,3,4,5 and distance runners numbered 1,2. Let S be the event of selecting a sprinter, D the event of selecting a distance runner, E the event of selecting an even numbered runner, and the event of selecting an odd runner. Selecting the sprinter numbered 1 is one outcome of which of the following events? Select all correct answers. Select all that apply: O DANDO ODORE DORO 00 OE' OS AND E
Answer:
D or O
E'
Step-by-step explanation:
Because the runner is a sprinter and the number is odd, the runner is an example of S and O. Therefore, it is also an example of E′ (not even) and D OR O.
For sprinter numbered 1 is outcome of S, D and O events.
Events to be determine that contain sprinter number 1. We have number of events that is for sprinter, distance runner, odd numbered, even numbered as S,D,O and E respectively.
Sample space = (1, 2, 3, 4, 5).
Probability can be defined as the possibility of the desired event to be happened.
Here, Numbered 1 is odd number, a sprinter and also a distance runner.
So, Numbered 1 is contain in S, D and O.
Thus, for sprinter numbered 1 is outcome of S, D and O events.

Given that Jocelyn saved $60 in 8 weeks, predict the number of weeks it will take Jocelyn to save $90. Include in your explanation any assumptions that must be made in order to make the prediction. Enter your explanation in the space provided.
number of weeks: w is the x value, and the number of money saved: m is the y value. First, we need to find out how much she makes in 1 w and because k = y/x, we need to divide 60 by 8, which gives u 7.5, so she saves $7.50 every week Finally, we figure out the number of weeks it takes her to save $90, and to do that, we use the formula x = y/k. Using that formula, we get the expression $90/$7.50 or $90/$7.5. 90/7.50 = 12, so x = 12. It will take her 12 weeks to save $90. In order to check our answer, we can say that we didn't know the number of m she saved, but we do know how many weeks. To find a solution, we use the formula y = kx (the blank between kx means that we are multiplying). Using that formula, we get the equation 12 X 7.50. When we solve this equation, we get 90, and since it is the same answer as the real problem, that means the answer for the real problem is correct. (BTW sorry this is so long)
If the Washington Monument is 3025 square feet and an average gallon of paint covers 400 square feet, how much paint would it take to cover it all up? PLEASE HELP WILL GIVE BRAINLIEST. I’m also wondering how I would go about solving this? I have a lot more.
Divide total area by area of a gallon of paint:
3025 / 400 = 7.56
Because there is a decimal answer you need to round up tot he next whole number.
You would need 8 gallons of paint.

Marc earns $45,000 per year. If he does not work for 2 months in a year, how much money would he earn?
Answer:
$37500
Step-by-step explanation:
45000 divided by 12 = 3750
3750 is how much he earns each month.
3750x2=7500
7500 is how much he earns in 2 months
45000-7500=37500
Answer:
37,500
Step-by-step explanation:
if he makes 45,000 a year, we need to find out how much he makes per month.
divide 45,00 by 12= 3750 per month
3750 times 2 months= 7500
45,000-7,500= 37,500

the spinner has three regions 5 0 and 20to play the game you spin one time and then you win the amount in the region that the spinner lands on. what is the expected valuse of the game
Answer:
Step-by-step explanation:
Each region is equally likely.
5 * 1/3 = 5/3 = 1 2/3 = 1.67
0 * 1/3 = 0
20*1/3 = 6 2/3 = 6.67
Total = 8.34
So if this really were a game you should be willing to put up 8.34 to play it.
You can create a simulation. Let the computer play 10000 times (which will take seconds). I'm going to try this for you. and see what happens.
You throw 0 3309 times
You throw 5 3394 times
You throw 20 3290 times
The net result is that you will win 2.71 as you pay, which is what it should be.

For f(x) = -x + 8, which statement is true?
Group of answer choices
f(x + k) = f(x) + k
f(x + k) = f(x) + f(k)

The boundary of a lamina consists of the semicircles y = 1 − x2 and y = 64 − x2 together with the portions of the x-axis that join them. Find the center of mass of the lamina if the density at any point is proportional to its distance from the origin.
Answer:
The center mass of the lamina = [tex]{\begin {pmatrix} 0, \dfrac{1755}{146 \pi } \end {pmatrix}[/tex]
Step-by-step explanation:
Let take a look at the boundary of the lamina that comprises of the semicircles [tex]y = \sqrt{1-x^2}[/tex] and [tex]y = \sqrt{64-x^2}[/tex]
We are also informed that the density at any point is proportional to its distance from the origin.
Thus, the main task required is to find the center mass of the lamina.
In as much as the density is proportional to the distance from the origin;
Then;
[tex]\rho (x,y) = k \sqrt{x^2 + y^2} = kr[/tex]
Thus; the mass of the lamina is determined as:
[tex]m = \iint \limits _ D \rho (x,y) \ dA= \int ^{\pi}_{0}\int ^{8}_{1} kr.r dr d \theta[/tex]
[tex]m = \int ^{\pi}_{0}\int ^{8}_{1} kr^2 dr d \theta[/tex]
[tex]m = k \int ^{\pi}_{0} \begin {bmatrix} \int \limits ^8_1 r^2 dr \end {bmatrix} d \theta[/tex]
[tex]m = k \int ^{\pi}_{0} \begin {bmatrix} \int \limits\dfrac{r^3}{3} \end {bmatrix} ^8_1d \theta[/tex]
[tex]m = k \int ^{\pi}_{0} \begin {bmatrix} \dfrac{512}{3}- \dfrac{1}{3} \end {bmatrix} d \theta[/tex]
[tex]m = \dfrac{511 \ k}{3} \int \limits ^{\pi}_{0} \ d \theta[/tex]
[tex]m = \dfrac{511 \ k}{3} \bigg (\theta \bigg ) ^{\pi}_{0}[/tex]
[tex]m = \dfrac{511 \ k \pi}{3}[/tex]
Now, about the y-axis, the moment of the entire lamina can be computed as:
[tex]M_y = \iint \limits _D x\rho (x,y) \ dA = \int \limits^{\pi}_{0} \int \limits ^{8}_{1} r cos \theta kr .r \ dr \ d \theta[/tex]
[tex]M_y = k \int \limits ^{\pi}_{0} \int ^{8}_{1} \ cos \theta . r^3 \ dr \ d \theta[/tex]
[tex]M_y = k \begin {bmatrix} \int \limits ^{\pi}_{0} cos \theta d \theta \end {bmatrix} \begin {bmatrix} \int \limits ^8_1 r^3 dr \end {bmatrix}[/tex]
[tex]M_y = k (sin \ \theta )^{\pi}_{0} \begin {bmatrix} \dfrac{r^4}{4} \end {bmatrix}^8_1[/tex]
[tex]M_y = k(sin \pi - sin 0 ) \bigg ( \dfrac{8^4}{4}- \dfrac{1^4}{4} \bigg)[/tex]
[tex]M_y = 0[/tex]
Similarly; about the x-axis, the moment of the entire lamina can be computed as:
[tex]M_x = \iint \limits _D y \rho (x,y) \ dA = \int \limits^{\pi}_{0} \int \limits ^{8}_{1} r sin \theta kr .r \ dr \ d \theta[/tex]
[tex]M_x = k \int \limits ^{\pi}_{0} \int ^{8}_{1} \ sin \theta . r^3 \ dr \ d \theta[/tex]
[tex]M_x = k \begin {bmatrix} \int \limits ^{\pi}_{0} sin \theta d \theta \end {bmatrix} \begin {bmatrix} \int \limits ^8_1 r^3 dr \end {bmatrix}[/tex]
[tex]M_x= k (- cos \ \theta )^{\pi}_{0} \begin {bmatrix} \dfrac{r^4}{4} \end {bmatrix}^8_1[/tex]
[tex]M_x = k(-cos \pi +cos 0 ) \bigg ( \dfrac{8^4}{4}- \dfrac{1^4}{4} \bigg)[/tex]
[tex]M_x = \dfrac{4095}{2}k[/tex]
Hence, The center mass of the lamina is:
[tex]( \overline x, \overline y) = \bigg ( \dfrac{M_y}{m}, \dfrac{M_x}{m} \bigg )[/tex]
[tex]( \overline x, \overline y) = \begin {pmatrix} \dfrac{0}{\dfrac{511 \ k \pi}{3}}, \dfrac{\dfrac{4095 \ k}{2}}{\dfrac{511 \ k \pi}{3}} \end {pmatrix}[/tex]
[tex]( \overline x, \overline y) = \begin {pmatrix} 0, \dfrac{1755}{146 \pi } \end {pmatrix}[/tex]

Complete question is;
In 1986, a family member invested $100 each month into a savings account with an interest rate of 0.25% (that didn't change). In 2016, you decided you needed to use that saved up money for a big purchase, so you cash the savings account out.
How much money should be in the account using the FV formula?
Answer:
FV = $107.78
Step-by-step explanation:
We are given;
Present value; PV = 100
Interest rate; r = 0.25% = 0.0025
We are told the PV was in 1986 and In 2016 you decided you needed to use that saved up money .
This is a period of 30 years.
Thus, the number of compounding periods is n = 30
Formula for FV is;
FV = PV(1 + r)ⁿ
FV = 100(1 + 0.0025)^(30)
FV = $107.78
