Answer:
- A
- Multiplying by 5
- Multiplying by 5
- Multiplying by 12.5
- Multiplying by 2
Step-by-step explanation:
Answer: no because it’s only 50 and you decided the number and the you decided the number of cities so it’s not random
Step-by-step explanation:
hours each day.
Step-by-step explanation:
The given function models the number of cars that are put through a quality control test each hour at a car production factory.
The given function is
We need to find the number of hours does the quality control facility operate each day.
Rewrite the given function it factored form.
Taking out the common factors from each parenthesis.
The factored form of given function is c(t)=-(t-10)(t+2).
Equate the function equal to 0 to find the x-intercept.
Number of hours cannot be negative. So from t=0 to t=10 quality control facility operate the cars.
Therefore the quality control facility operates for 10 hours each day.
Answer:
8/7
Step-by-step explanation:
0.8/0.7=8/7
The equation most closely models the line of best fit for the scatter plot is y = 2.5x
<h3>Equation of a line</h3>
A line is the distance between two points. The equation of a line in point-slope form is given as y =mx + b
where:
m is the slope or rate of change
b is the intercept
Using the coordinate points on the line (3, 5000) and (9, 20000)
Get the rate change(slope)
Slope = 20000-5000/9-3
Slope = 15000/6 = 2500
Determine the y-intercept by substituting
5000 = 2500(3) + b
b = 5000 - 7500
b = -2500
Determine the equation
y = 2.5x - 2.5
Hence the equation most closely models the line of best fit for the scatter plot is y = 2.5x
