Answer:
1. 52
2. 2.9
Step-by-step explanation:
To find the mean, we take all the numbers, add them up then divide by the number of numbers.
1. mean height
mean = (50+54+52+56+48)/5
=260/5
=52
52 inches
2. mean score
There are 5+3+12+2+6+6+4 students = 38 students
Multiply the number of students times the score and add together
total points = (0*5+1*3+2*12+3*2+4*6+5*6+6*4)
= 111
The mean is the total points divided by the number of students
mean = 111/38
=2.92
The diameter of what i hpe its a circle because if so then <span>The radius is the distance from the center of the </span>circle<span> to its edge. For example, if the radius of the </span>circle<span> is 4 cm, then the </span>diameter<span> of the </span>circle<span> is 4 cm x 2, or 8 cm. If you</span>know<span> the circumference of the </span>circle<span>, divide it by π to get the </span>diameter<span>.</span>
