Find the average value of the following numbers 87, 79, 84, 70, 90

dem82 [27]

Explanation

the average is calculated by dividing the sum of the values in the set by their number.

Step 1

Let

$\begin{gathered} \text{set}=\lbrace87,79,84,70,90\rbrace \\ the\text{ sum of the values is=87+79+84+70+90}=410 \\ n\text{umber of values= 5} \end{gathered}$

Step 2

apply the equation

$\text{Average}=\text{ }\frac{the\text{ sum of the values}}{\nu mber\text{ of values}}=\frac{410}{5}=82$

so, the answer is 82

Ms. Rodriguez gave a test that had 42 questions consisting of Multiple Choice and short answer questions. If the test is worth 6

egoroff_w [7]

Answer:

There are 33 multiple choice questions and 9 short answer questions on the test

Step-by-step explanation:

In this question, we are asked to calculate the number of multiple text answers and short answers given in a test, given that the test taker will attempt a number of questions and have a particular score.

Since we do not know the number of these questions individually, let’s represent them with variables. Let the number of multiple choice questions to be answered be x and the number of short answers questions to be given be y.

Mathematically,

x + y = 42. (I)

Also, the total points is 60, with multiple choice of 1 point each and short answers of 3 points each. Mathematically, this means;

x(1) + y(3) = 60.

x + 3y = 60. (ii)

Now let’s solve both 1 and 2 simultaneously.

From 1, let’s say y = 42-x and substitute this in 2

x +3(42-x) = 60

x + 126 -3x = 60

-2x = 60-126

2x = 66

x = 66/2
