Answer:

18, 23

Step-by-step explanation:

a. We know that W = 5 and D = 3 so:

P = 3W + D = 3 * 5 + 3 = 18 points

b. We know that P = 50 and D = 14 and that we are solving for W so we get:

50 = 3W + 14

36 = 3W

W = 12 which means the losses are 35 - 12 = 23.

(a) Given:

number of wins = 5

and, number of draws = 3

To find :

Point of the team.

Solution:

P = 3*5 + 3

= 18

Point of the team = 18

(b) Given:

number of points = 50

and, number of draws = 14

To find :

Number of games lost by the team.

Solution:

50 = 3*win + 14

3*win = 36

win = 12

Number of games lost by the team = 35 - 12 =23

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2700 grams and a standard deviation of 900

rosijanka [135]

Answer:

The 33 week gestation period baby has a zscore of -0.47.

The 41 week gestation period baby has a zscore of -0.94.

The 41 week gestation period baby weighs less relative to the gestation period.

Step-by-step explanation:

Normal model problems can be solved by the zscore formula.

On a normaly distributed set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a value X is given by:

$Z = \frac{X - \mu}{\sigma}$

The zscore represents how many standard deviations the value of X is above or below the mean $\mu$ . This means that the baby with the lowest Zscore is the one who weighs relatively less to the gestation period.

33 week gestation period baby:

Babies born after a gestation period of 32 to 35 weeks have a mean weight of 2700 grams and a standard deviation of 900 grams, so $\mu = 2700, \sigma = 900$ .

A 33-week gestation period baby weighs 2275 grams. So $X = 2275$ .

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{2275 - 2700}{900}$

$Z = -0.47$

41 week gestation period baby:

Babies born after a gestation period of 40 weeks have a mean weight of 3200 grams and a standard deviation of 450 grams, so $\mu = 3200, \sigma = 450$
