Ned got an overall grade of 86 percent because if each question is 4 points, then 6×4=24 but if he got a bonus 10 points, then you can do 24-10=14 and then you do 100-14 which equals your answer: 86.

-6 × 4 = -24
-24 + 10 = -14
100 - 14 = 86 points

8. A box is filled with candies in different colors. We have 40 white candies, 24 green ones, 12
Darya [45]

Answer:

P(Green\ or\ Red) = 0.30

Step-by-step explanation:

Given

White = 40

Green = 24

Red = 12

Yellow = 24

Blue = 20

Required

P(Green\ or\ Red)

The total numbe of candy is:

Total = 40 + 24 + 12 + 24 + 20

Total = 120

This probability is calculated as:

P(Green\ or\ Red) = P(Green) + P(Red)

For each, we have:

P(Green\ or\ Red) = \frac{Green}{Total} + \frac{Red}{Total}

Take LCM

P(Green\ or\ Red) = \frac{Green+Red}{Total}

P(Green\ or\ Red) = \frac{24+12}{120}

P(Green\ or\ Red) = \frac{36}{120}

P(Green\ or\ Red) = 0.30

Nastasia [14]
815 x 360 =  293,400 gal per second.

293,400 gal ÷ 4 quarts = 73,350 quarts per sec.

I'm fairly certain that's right - someone correct me if I'm mistaken.
