So I’ll do question 3. So normally you see f(x)= something plus x (something like that) you see it as a function of x.

So that notation of f(-1) means the function of -1. Which means you need to sub in -1 for x.

f(x)=-5x+5
f(-1)=-5(-1)+5
Negative times a negative is a positive
f(-1)=5+5
f(-1)=10

Translate the sentence into an equation, then solve the
Oduvanchick [21]

Answer:

The equation is: \frac{x-7}{5} = 13 and the number is 72.

Step-by-step explanation:

We have to use mathematical notation to convert the given statement into an equation. As we don't know the exact value of number, we have to use a variable in place of the number.

Let x be the required number then

"A number decreased by 7"

x-7

"and then  divided by 5"

\frac{x-7}{5}

" is 13."

\frac{x-7}{5} = 13

For solving, multiplying both sides of equation by "5"

\frac{x-7}{5} * 5 = 13*5\\x-7 = 65

Adding 7 on both sides of equation

x-7+7 = 65+7\\x = 72

Hence,

The equation is: \frac{x-7}{5} = 13 and the number is 72.

If the outliers are not included, what is the mean of the data set? 76, 79, 80, 82, 50, 78, 83, 79, 81, 82 (2 points) Select one
wlad13 [49]
Hello!

As you can see, 50 is the outlier, as it is not around the other numbers in the data set. Therefore, we will calculate the mean of all the numbers if we add up all the numbers and divide by 9.

(76+79+80+82+78+83+79+81+82)÷9=80

The mean of this data set (excluding the outlier) is 80.

I hope this helps!
