Answer:
always
Step-by-step explanation:
Travel at the speeds of 65 miles per hour to drive the distance of 310 miles (if the speed in which the person in question is traveling at the same speed) =
310 divided by 65 =
= 4 and
![\frac{10}{13}](https://tex.z-dn.net/?f=%20%5Cfrac%7B10%7D%7B13%7D%20)
hours
since it is "traveled distance = speed multiplied by time it takes
D = 144 - 16t^2
144 - 16t^2 ≥ 0
16(9 - t^2) ≥ 0
9 - t^2 ≥ 0
9 ≥ t^2
t ≥ + or -3
Required interval is 0 ≤ t < 3
Answer:
The average repair cost per saw for the past month is 20.
The bound of error of estimation is ±10.
Step-by-step explanation:
a) Data and Calculations:
Industry No.of saws Total repair cost Average
for past month
1 3 50 16.67
2 7 110 15.71
3 11 230 20.91
4 9 140 15.56
5 2 60 30
6 12 280 23.33
7 14 240 17.14
8 3 45 15
9 5 60 12
10 9 230 25.56
11 8 140 17.50
12 6 130 21.67
13 3 70 23.33
14 2 50 25
15 1 10 10
16 4 60 15
17 12 280 23.33
18 6 150 25
19 5 110 22
20 8 120 15
Total 130 2,565 19.73
Average = Sum of the total repair cost for past month divided by the number of saws repaired
= 19.73 (2,565/130)
= 20
The bound on error of estimation = the difference between the upper bound of the interval and the calculated mean
= 30 - 20
= 10
The lower bound = 10
The bound of error is also = (30 -10)/2 = 10
Answer:
32 tablespoons
Step-by-step explanation:
1/4 of a cup has 4 table spoons
therefore, a whole cup = 4+4+4+4= 16
2 cups = 16 x 2 = 32
1 pint = 2 cups therefore 32 tablespoons
