<h3>The time in fourth race is 43.04 seconds</h3>

<em><u>Solution:</u></em>

Given that,

Shelly is trying to improve her running time for a track race

She ran the first race in 43.13 seconds

Her time was 43.1 seconds in the second race and 43.07 seconds in the third race

<em><u>Therefore, pattern is:</u></em>

43.13, 43.1, 43.07 , ..

<em><u>Find the difference between each terms</u></em>

d = 43.13 - 43.1 = 0.03

d = 43.1 - 43.07 = 0.03

Thus the difference is same

<em><u>If this pattern continues what will shellys time be in the fourth race?</u></em>

Fourth race = third race - 0.03

Fourth race = 43.07 - 0.03 = 43.04

Thus the time in fourth race is 43.04 seconds

Compute the mean and variance of the following probability distribution. (Round your answers to 2 decimal places.) x P(x) 7 0.10
Alex777 [14]

Answer:

14.2, 16.96

Step-by-step explanation:

given is a probability distribution of X

X is discrete taking values as 7, 11, 15 and 19

X          7            11        15        19          total

p           0.10     0.35    0.20   0.35          1

x*p         0.7     3.85     3.0     6.65       14.20

x^2*p     4.9     42.35   45      126.35 218 .60

Hence mean = sum of prob (x) = 14.20

E(x^2) =218.60

Var(x) = E(x^2)-{E(x)}^2\\= 218.60-14.20^2\\= 16.96
