Two Physics classes at Jefferson High School took the same quiz. Mr. Spears had 20 students in his class with a mean score of 80
andriy [413]

Answer:

The mean score for all students on the quiz was 86.

Step-by-step explanation:

This question is solved by a weighed average.

To find the weighed average, we add the values multiplied by their weight, and after that we divide by the sum of weights.

In this problem, we have that:

Mr. Spears had 20 students in his class with a mean score of 80.

So 80 has a weight of 20.

Mrs. Guyton's class of 30 students had a mean score of 90.

So 90 has a weight of 30.

Overall, what was the mean score for all students on the quiz

M = \frac{80*20 + 90*30}{20 + 30} = 86

The mean score for all students on the quiz was 86.

A homeowner wants to increase the size of a rectangular deck that now measures 14 feet by 22 feet. The building code allows for
Bumek [7]

Answer:

10.6 feet

Step-by-step explanation:

Length = 22ft

width= 14ft

Maximum area = 800 sq. ft

Let X be increase in the number of feet for the length and width.

The new length = (22 + x) ft

New width= (14 + x) ft

Area = (22+x)(14+x) ≤ 800

308 + 36x + x^2 ≤ 800

x^2 + 36x + 308 - 800 ≤ 0

x^2 + 36x - 492 ≤ 0

Solve using quadratic equation

x = (-b +/- √b^2 - 4ac) / 2a

a= 1, b = 36, c= 492

x = (-36 +/- √36^2 - 4*1*-492)/ 2*1

= (-36 +/- √1396 + 1968) / 2

= (-36 +/- √3264) / 2

= (-36 +/- 57.13) / 2

x = (-36 + 57.13)/2 or (-36 - 57.13)/2

x = 21.13/2 or -93.13/2

x = 10.6 or -31.0

x = 10.6 ft

The length and width must increase by 10.6 ft each
