When finding the mean you add up the numbers that are needed to find the mean and divide them by the amount of numbers you added. For example question 5 you will add 58+58+62+55+49+48 which will equal 330 and then divide it by 6 because there are 6 numbers which is 55.
Answer:
x = 18°
y = 6
Step-by-step explanation:
in a parallelogram:
Any two opposite sides are congruent
and any two opposites angles are congruent:
then
y + 4 = 10
and 3x = 54
then
y = 6
and x = 54/3 = 18
Median of (72 82 92 93 94 97 98 102)
Median: 93.5
MAD : 7.125
Median of ( 53 59 64 65 65 66 67 69)
Median : 65
MAD : 3.75
Answer:
Step-by-step explanation:
By putting the numbers in the given equation,
2x + 3 + 3x = 7x + 9
5x + 3 = 7x + 9
(5x + 3) - 7x = (7x + 9) - 7x
(5x - 7x) + 3 = 9
-2x + 3 = 9
(-2x + 3) - 3 = 9 - 3
-2x = 6
-x = 3
x = -3
Therefore, our equation is correct which has a negative result.
In place of 6 if we use 8, value of x will be negative again.
