First find how many quarts are made per hour.

To do this, divide 330 quarts by 5 hours:
330  \div 5
This gives you 66 quarts per hour.

Multiply this by 12 to find out how much is made in 12 hours.
66 \times 12
Answer: 792 quarts

A theater group surveyed 146 audience members after a show and found that 132 of them wanted to see the show again. Find the sta
Sophie [7]

Answer:

0.024

Step-by-step explanation:

Sample size (n) = 146 people

The proportion (p) of people who answered that they would be interested in seeing the show again is:

p=\frac{132}{146}\\ p=0.9041

The standard error for a sample of size 'n' and proportion 'p' is:

SE = \sqrt{\frac{p*(1-p)}{n}}\\SE = \sqrt{\frac{0.9041*(1-0.9041)}{146}}\\ SE=0.024

The standard error for the sample proportion of audience members who want to see the show again is 0.024.

If B is the midpoint of AC, AC=CD, AB=3x+4, AC=11x-17, and CE=49, find DE.
Luba_88 [7]

Answer:

11

Step-by-step explanation:

AB = 3x + 4 and AC which is twice of AB is equal to 11x - 17

2 (3x + 4) = 11x - 17

6x + 8 = 11x - 17

8 + 17 = 11x - 6x

25 = 5x

5 = x

AC = CD = 11x - 17 ➡ 11×5 - 17 = 38

CD = 38 and DE = 49 - 38 = 11
