Answer:

14,621 lbs.

Step-by-step explanation:

It says at the beginning of the question that the school district collected 14,621 lbs. of recycling. The part where it says that the school district collected 3,943 lbs. of recycling more than last year is un-needed information.

answer:

505155

step-by-step explanation:

  • multiply, add, and subtract the first two numbers of the equation in that order to get the final number

8 + 2 = 16106: 8 x 2 = 16, 8 + 2 = 10, 8 - 2 = 6 to get the number 16106

5 + 4 = 2091: 5 x 4 = 20, 5 + 4 = 9, and 5 - 4 = 1 to get the number 2091

9 + 6 = 54153: 9 x 6 = 54, 9 + 6 = 15, and 9 - 6 = 3 to get the number 54153

7 + 5 = 35122: 7 x 5 = 35, 7 + 5 = 12, and 7 - 5 = 2 to get the number 35122

20 + 3 = 602317: 20 x 3 = 60, 20 + 3 = 23, and 20 - 3 = 17 to get the number 602317

30 + 1 = 303129: 30 x 1 = 30, 30 + 1 = 31, and 30 - 1 = 29 to get the number 303129

18 + 4 = 722214: 18 x 4 = 72, 18 + 4 = 22, and 18 - 4 = 14 to get the number 722214

10 + 5 = 505155: 10 x 5 = 50, 10 + 5 = 15, and 10 - 5 = 5 to get the number 505155

In a sample of 150 cars, 18 cars failed a safety inspection. The sampling method had a margin of error of 0.02
mestny [16]

Answer:  

(Lower limit, Upper limit) = (0.10, 0.14)

(Lower limit, Upper limit) = (10%, 14%)

Step-by-step explanation:  

Total number of cars = 150

Cars that failed the safety inspection = 18

The proportion is given by

p = 18/150

p = 0.12

p = 12%

The confidence interval is given by

p ± margin of error

Where margin of error is 0.02

0.12 ± 0.02

Lower limit = 0.12 - 0.02

Lower limit = 0.10

Lower limit = 10%

Upper limit = 0.12 + 0.02

Upper limit = 0.14

Upper limit = 14%

(Lower limit, Upper limit) = (0.10, 0.14)

(Lower limit, Upper limit) = (10%, 14%)
