400x to the power of 2 + 480x + 144
I'd say angle A = angle B
arc tangent (angle B) = 150 / 555

angle B = 15.124 degrees
By the way 555 feet is the height of the Washington Monument.

Answer: 1) 1/3,654 2) 3/406 3) 72,684,900,288,000 4) 120
<u>Step-by-step explanation:</u>
1) First and Second and Third
2) First and Second
The numbers 1 to 72 add up to (1+72) x 72/2 = 73 x 36 = 2628
If we take away what Josh got we have 2628 - 2521 = 107
Pages in a book are odd on the first side and even on the second, so pages 11 and 12 are on the same sheet.
107 / 2 = 53.5 so the missing page had 53 on one side and 54 on the other side.
The remaining pages would have been numbered 1, 2, 3, ..., 51, 52, 55, 56, ... 71, 72
Answer:
(D) 15.90 to 16.20 ounces
Step-by-step explanation:
Confidence Interval = mean + or - (t×sd)/√n
Mean = 16.05 ounces, sd = 0.1 ounce, n = 4, degree of freedom = n - 1 = 4 - 1 = 3, t = 3.182
Lower limit = 16.05 - (3.182×0.1)/√4 = 16.05 - 0.15 = 15.90 ounces
Upper limit = 16.05 + (3.182×0.1)/√4 = 16.05 + 0.15 = 16.20 ounces
The sample mean will fall from 15.90 to 16.20 ounces
