Find the mean and range.

26 19 23 39 31 34 23 25

QUESTION 1

The given data set is;

The mean can be found using the formula;

QUESTION 2

To find the range we may sort the data to obtain;

We see that the maximum value is 39 and least value is 19

The range is the largest value minus the least value.

This implies that;

c. 65°

step-by-step explanation:

we are given a triangle with two known angles, 62° and 53°, while the third angle x is unknown and we are to find its value.

we know that the sum of angles in a triangle is equal to a total of 180 degrees. so we can write it as:

x + 62° + 53° = 180°

solving to find the value of x:

x = 180 - (62 + 53) = 65°

therefore, the value of x in this triangle is 65°.

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.
