88, 92, 76, 42, 88, 90, 100, 110, 115, 5, 88, 92, 95

salantis [7]

Answer:

Mean = 83.15

Median = 90

Mode = 88

Range = 110

Outlier = 5

Step-by-step explanation:

Mean - (88+92+76+42+88+90+100+110+115+5+88+92+95)/2 = 83.15

Median - 5, 42, 76, 88, 88, 88, <u>90</u>, 92, 92, 95, 100, 110, 115 = 90

Mode - <u>88</u>, 92, 76, 42, <u>88</u>, 90, 100, 110, 115, 5, <u>88</u>, 92, 95 = 88

Range - 115 - 5 = 110.

Outlier - 88, 92, 76, 42, 88, 90, 100, 110, 115, <u>5</u>, 88, 92, 95 = 5

Which of the following is the solution for 7 - 4x ≥ 35 ?

melamori03 [73]

There are no solutuons listed (says which of the following). My answer below should be in the list to choose from.

7 - 4x ≥ 35
subtract 7 from both sides

-4x ≥ 28
divide both sides by -4 AND change the direction of the inequality sign because we're dividing by a negative

x ≤ -7

CHECK:
7 - 4x ≥ 35
7 - 4(-7) ≥ 35
7 + 28 ≥ 35
35 ≥ 35

ANSWER: x ≤ -7

Hope this helps! :)
