The answer in B. For complicated statistics reasons the Central Limit Theorem states that, for sample sizes of above 25 (or 30 depending on the text!), the distribution of sample means is approximately normal regardless of the distribution of the parent distribution

Hello,

1) k = (-5) * (-5) = 25

3) x = 12 * 0 = 0

5) y = (-4) * (-12) = 48

7) z = 0 * 9 / 1 = 0

9) x= 18 / -3 = -6

11) p = -8 / 8 = -1

13) h = 42 / 14 = 3

15) m = -42 / 6 = -7

17) x = -9 * -11 = 99

19) v = -17 / -17 = 1

21) h = 3,136 / 56 = 0,056

23) x = 4,200 / 30 = 0,14

25) m = 21 * -3 = -63

Bye :)

Enguun earns $17 per hour tutoring student-athletes at Brooklyn University.
Juliette [100K]

Answer:

a. Earnings of Enguun for 12 hours this month (G)

G = 204 dollars

b. Earnings of Enguun for  19.5 hours last month (G)

G = 331.5 dollars

Step-by-step explanation:

Nomenclature

G: Total earnings of Enguun in dollars

E: Enguun's earnings for 1 hour of tutoring (dollars/hour)

n: number of hours that Enguun tutored per month (hour/month)

Formula

G = E*n

E = $17 per hour = 17 dollars/hour

Problem development

a. Earnings of Enguun for 12 hours this month

n = 12 hours

G = E*n

G= 17\frac{dollars}{hour} * 12 hour  : We eliminate hours

G = 204 dollars

b. Earnings of Enguun for 19.5 hours last month

G = E*n

G = 17 * 19.5

G = 331.5 dollars
