1 The heights of 9 students of a class are as follows (in cm):

1 answer:

4 0

You only listed 8 kids...so the average of the 8 kids listed is 150.125!
The process:
You add all kids heights then divide by the amount of children. Like this-
155+160+145+150+147+152+144+148=1201
Then you divide by 8 to get 150.125

A high school basketball coach is selecting his team. The minimum and maximum height requirements are as follows:

daser333 [38]

Answer:

B. About 2% of the boys are eligible to be a small forward on the team

Step-by-step explanation:

Recall : 1 feets = 12 inches

Point guard = 6’2" – 6’6" tall = 74 - 78 inches

Mean = 70 ; Standard deviation = 4

Z = (x - mean) / standard

P(x < 74) = (74 - 70) / 4 = 1

P(x < 78) = (78 - 70) / 4 = 2

0.97725 - 0.84134 = 0.13591

Small forward : 6'6" = 78 inches

P(x ≥ 78) = (78 - 70) / 4 = 2

P(z ≥ 2) = 0.02275 = 2.275% about 2%

Centre : 6'8" = 80

P(x ≥ 80) = (80 - 70) / 4 = 2.5

P(z ≥ 2.5) = 0.0062097 = 0.62%

The centroid splits the median in a 2:1 ratio from vertex to side.
The median bisects the side it is drawn to.

$QR=(1/2)(JQ)=(1/2)(16)=8 \\ \\ LM=(3)(QM)=(3)(6)=18 \\ \\ KQ=(2/3)(KP)=(2/3)(18)=12$

Two-thirds of the students in a class are wearing blue jeans.Two-sixths of the students who are wearing blue jeans are also wear

Vesnalui [34]

Given Two-thirds of the students in a class are wearing blue jeans

.Or $\frac{2}{3}$ Of students wear blue Jeans.

Number of students wearing red shirts is Two-sixths of the students who are wearing blue jeans .

Number of students wearing red shirts = $\frac{2}{6} of\frac{2}{3}$

Simplifying we have:

$\frac{2}{6} of\frac{2}{3} =\frac{4}{18} = \frac{2}{9}$

Fraction of the students in the class are wearing blue jeans red shirts = $\frac{2}{9}$
