Answer:
A) 2
Step-by-step explanation:
I<em>n a box-and-whisker plot, the left "whisker" is the bottom 25%, the line between the two "boxes" is to 50%, and the right "whisker" is the top 25%</em>.
In class 2, the 90 point mark is where the line between the boxes are, which means that 50% of the class earned 90% or less. That is 13/2 = <em>6.5 people</em> (this is impossible but it will work out)
In class 1, the 80 point mark is also where 50% is. So, half of the students, 17/2 = <em>8.5 people</em>, have 80 points or less.
<em>8.5 - 6.5 =</em> 2 people.

Answer:
200 in2
Step-by-step explanation:
diameter= 15 in. so raduis = 15/2
area of circle = πr2
= 22/7 * 15/2 *15/2
= 176.79
rounding to the nearest 100, its 200 in2
4 people = 480 grams of pasta
1 person = 480 ÷ 4 = 120 grams of pasta
14 people = 120 x 14 = 1680 grams of pasta
1680g = 1680 ÷ 1000 = 1.68 kg
Answer: 1.68 kg of pasta
