Answer:
See explanation below
<u>Step-by-step explanation:</u>
range = 2200 - 300 = 1900
To find standard deviation, we have:
standard deviation = range/4 =
= 475
The range rule of thumb estimate for the standard deviation is 475
Given:
Standard deviation,
= 475
Margin of Error, ME = 100
= 1 - 0.90 = 0.10
Za/2 = Z0.05 = 1.64
Find sample size, n:
n ≥
n ≥
n ≥ 60.68
≈ 61
Minimun sample size,n = 61
Hi there!
First we subtract 44-14 leaving us with 30. 5x6 = 30
Therefore, a member can visit a history museum 6 times to equal a total cost of $44.
In a different situation:
If the person has already paid the $14, and that doesn’t count as a visit, then a person would have to visit a museum 8 times to get a total of $45. Considering this is a real-world problem.
I hope this helps and have a good day :) !

Answer:
$74.53
Step-by-step explanation:
16%=0.16
0.16*64.25+64.25
=(0.16+1)*64.25
=$74.53
Answer:
77 m
Step-by-step explanation:
The geometry can be modeled by a right triangle. The distance from the viewpoint to the base of the tower is 110 m, the leg of the triangle adjacent to the angle. The height of the spire is the leg of the triangle opposite the given angle. The relevant trig relation is ...
Tan = Opposite/Adjacent
__
Using the given numbers, we find ...
tan(35°) = height/(110 m)
height = (110 m)tan(35°) = (110 m)×0.700208 ≈ 77.0 m
The height of the tower is about 77 meters.
8:15 a.m to 12:45 p.m......4 hrs 30 min
took 45 min lunch (not paid)....now its 1:30 p.m.....
1:30 p.m. to 6:45 pm = 5 hrs 15 min
5 hrs 15 min + 4 hrs 30 min = 9 hrs 45 min or 9 3/4 hrs
$ 16 for first 8 hrs......overtime pay is $ 24 per hr....leaving 1 hr and 45 min or 1 3/4 hrs overtime
16 + 24(7/4) = 16 + 42 = $ 58 <===
