The mean of five numbers 3,7,9,12, and x is 8. Find the value of x
jeyben [28]
Answer:  " x = 9 "  .
____________________________________
Explanation:
____________________________________
To calculate the mean:
____________________________________
The mean = 

     {the sum of all the values in the number set} ÷ 

     {the number of values in the data set} ;
____________________________________
 To solve for "x" ;
____________________________________
Given that the "mean" is:  "8" ;
____________________________________
            8  =  { 3 + 7 + 9 + 12 + x }  /  5  ;
____________________________________ 
    ↔  { 3 + 7 + 9 + 12 + x }  /  5   =  8  ;
____________________________________
            →  { 3 + 7 + 9 + 12 + x }  = 8 * 5  ;
____________________________________
            →  { 31 + x } = 40  ;
____________________________________
            ↔   x + 31  = 40  ;
____________________________________
       Subtract "31" from EACH SIDE of the equation; to isolate "x" on one side of the equation; and to solve for "x" ;
____________________________________
            →   x + 31 − 31  =  40 − 31  ;

                       →  x = 9  .

Giving Brainliest!<br> Explain the difference between low and high-frequency waves
Alinara [238K]

Answer:

Frequency refers to the number of waves that pass a given point in a given time period and is often expressed in terms of hertz (Hz), or cycles per second. Longer wavelengths will have lower frequencies, and shorter wavelengths will have higher frequencies

HELPPP please thank you so much
slavikrds [6]

Answer:

Inequality: 8p ≤ 50

Answer: p ≤ 6

Step-by-step explanation:

Step 1. Write an equation

$8 per person = 8p (where 8 is the cost per person and p is the number of people)

8p ≤ 50

Step 2. Solve

8p ≤ 50

÷8    ÷8

p ≤ 6.25 ≈ p ≤ 6 (your final answer is 6 because you cannot have 1/4 of a friend)

A regular assignment has 15 sides.Calculate the size of each interior angle
MariettaO [177]

Answer:

The measure of an interior angle of a regular 15-gon is 120°.

Step-by-step explanation:

We need to determine the measure of the size of an interior angle of a regular 15-gon having 15 sides.

Thus,

The number of sides n = 15

Hence,

Using the formula to determine the measure of an interior angle of a regular 15-gon is given by

(n - 2) × 180° = n × interior angle

substitute n = 15

(15 - 2) × 180 = 15 × interior angle

13 × 180 = 15 × interior angle

Interior angle = (10 × 180) / 15

                      = 1800 / 15

                      = 120°

Therefore, the measure of an interior angle of a regular 15-gon is 120°.
