The mean of the scores to the nearest 10th digit will be 74.9.

<h3>What is Mean?</h3>

The mean is the straightforward meaning of the normal of a lot of numbers. In measurements, one of the markers of focal propensity is the mean.

Then the mean is given as,

Mean = (Total score) / (total student)

The total score will be

Total score = 65 x 8 + 70 x 7 + 75 x 3 + 80 x 8 + 85 x 3 + 90 x 2 + 95 x 2

Total score = 520 + 490 + 225 + 640 + 225 + 180 + 190

Total score = 2470

The total number of students will be

Total student = 8 + 7 + 3 + 8 + 3 + 2 + 2

Total student = 33

Then the mean will be

Mean = 2470 / 33

Mean = 74.85 ≈ 74.9

More about the mean link is given below.

Find the values of x and y
LenKa [72]

Answer:

x = 1

y = -1

Step-by-step explanation:

A*B= (4y-8 3x-3)

1-) (4×2)+(3×y)= 3y+8

2-) (4×x)+(3×(-1))= 4x-3

AB=C

(3y+8 4x-3)=(5 1)

So

3y+8=5 ; y= -3/3 = -1

4x-3=1 ; x=4/4 =1

Evaluate 3^2018 + 3^2015 / 3^2017 + 3^2016
Harlamova29_29 [7]

The simplified value of the expression given as 3^2018 + 3^2015 / 3^2017 + 3^2016 is 7/3

<h3>How to evaluate the expression?</h3>

The expression is given as:

3^2018 + 3^2015 / 3^2017 + 3^2016

Factor out 3^2015 in the expression

So, we have

3^2015(3^3 + 1)/3^2015(3^2 + 3)

Cancel out the common factor

(3^3 + 1)/(3^2 + 3)

Evaluate the exponents

(27 + 1)/(9 + 3)

This gives

28/12

Simplify

7/3

Hence, the simplified value of the expression given as 3^2018 + 3^2015 / 3^2017 + 3^2016 is 7/3
