What is the equation of the graph below

aksik [14]

Answer:

The answer is B) y = Sin(3x)

Step-by-step explanation:

In order to find this, you need to look for how long it takes the period to repeat. This means other than the origin, we need to find the next place that the graph hits y = 0. In this case, it is at 2 $\pi$ /3. Since Sin2 $\pi$ = 0, we need what is inside of the parenthesis to equal 2 $\pi$ .

The only thing that you could multiply 2 $\pi$ /3 by to get 2 $\pi$ m is 3. Therefore, we must have 3x in the original equation.

Sharon will borrow $3400 at 11% APR. She will pay it back over 18 months. What will her monthly payment be?

omeli [17]

The first step to calculate the APR is to calculate the interest rate per $100

Here Interest rate = 11%

Term or time of repayment = 18 months

interest per $100 =

$100 × 11% × $\frac{18}{12}$

= $16.50

Now we should calculate the interest part for $3400 for 18 months

$\frac{3400}{100}$ × $\frac{16.50}{18}$

= $31.12

So $ 31.17 is the interest part of the repayment amount

Now lets calculate the principal part which would be $ 3400 divided equally for 18 months

$\frac{3400}{18} = $188.89$

Now to find the final payment we add the interest and the principal part

$31.17+$188.89 = $220.06

Hence option D is the right answer

What is the mean, median, and standard deviation for the following set of scores: 24, 20, 16, 18, 18, 26, 22? Please show your w

MissTica

Answer:

first: Definitions

mean: the average or the most common value in a collection of numbers

(So u add all numbers and then divide the answer by how much numbers there were)

median: Is middle value.

(example: 4, 5, 6) (The median will be the middle which is 5) (But if there are even amount of numbers like this: 4, 5, 6, 7) (Then you will get the two middle numbers which in this case are 5 and 6 you add them and then divide by 2.)

standard deviation: measures the spread of the data about the mean value

Step-by-step explanation:

Now lets get to problem!

we have numbers:

24, 20, 16, 18, 18, 26, 22

the mean will be: 144 (remember now you have to divide by 7 because there are 7 numbers.)

So it would be 20.57

Now the median:

(Since there are 7 numbers you just find the number in the middle and that would be ur median.)

24, 20, 16, 18, 18, 26, 22

median answer: 18

Like we said: The sample standard deviation measures the spread of a data distribution of the sample. It is usually used to estimate the population standard deviation

So the standard deviation will be: 3.6

I hope this helps :)

PLEASE HELP!! MATH FINAL

DaniilM [7]

Answer:

12 dimes, 8 nickels

Step-by-step explanation:

1. Set up an equation. Since we know the relationship between how many dimes and how many nickels that he has, we can create values for them.

2. Say that the number of nickels is x, so the number of dimes would be 2x-4.

3. Since we know that all of the coins that he has is 20 coins, we can say that 2x-4+x=20.

4. Solve the equation. We get 3x=24, and x=8.

5. That means that the number of nickels is 8, and the number of dimes is 2(8)-4, which is 12.

Answer: Timmy has 12 dimes and 8 nickels.
