Step-by-step explanation:
I did the work.
Answer:
D
Step-by-step explanation:
You are expected to apply your knowledge of the real world to the given situations in order to identify whether the "rate of change" is constant. A constant rate of change means the dependent variable has a linear relationship to the independent variable.
__
<h3>A</h3>
The independent variable is the outside temperature. The dependent variable is the number of people going to the beach. While the number of people going to the beach may increase as the temperature increases, the relationship is unlikely to be linear.
<h3>B</h3>
Points are scored unevenly during a ball game, so cannot be said to have a linear relationship with time played.
<h3>C</h3>
An acrobat flipping on a trampoline has increasing, then decreasing height. Height does not have a constant rate of change with respect to time.
<h3>D</h3>
If bananas are sold by the pound, then the price will be proportional to the weight of the bananas. The rate of change is the constant of proportionality: the price per pound. This situation has a constant rate of change.
Answer: 19,683 pennies

Answer:
Ratio of coco mix to water is 2 : 3.
Step-by-step explanation:
Given that:
Lindsey used 3 cups of water to 2 tsp of coco mix to make chocolate.
Ratio is the quantitative relationship between two amounts.
Ratio of coco mix to water.
Tsp of coco mix : Cups of water
2 : 3
Hence,
Ratio of coco mix to water is 2 : 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
