Answer:

85.5

Median: The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers). When there is an even number of terms, add the two middle terms and divide by 2.

Step-by-step explanation:

79, 83, 88, 93

83 + 88 = 171

171 ÷ 2 = 85.5

Solve <br> 6x - 5 = 13 – 3x
kirill115 [55]

Answer:

x = 2

Step-by-step explanation:

6x - 5 = 13 – 3x

Add 3x to both sides

6x + 3x - 5 = 13 - 3x + 3x

9x - 5 = 13

Add 5 to both sides

9x - 5 + 5 = 13 + 5

9x = 13+5

9x = 18

Divide both sides by 9

9x/9 = 18/9

x = 2

Furkat [3]

Answer:

The correct answer is C. 224

Step-by-step explanation:

Sn = n/2 (2*A1 +d(x-1))

S7=7/2(2*17+5(7-1))

S7=7/2(34+30)

S7=7/2(64)

S7=7*64/2

S7=7*32/1

S7=224
