Hello there,
To find out the equation you need to use slope intercept form...
y = mx + b
The only equation above that follows that form is...
y = 2x
Hope I helped!!

Answer:
87
Step-by-step explanation:
earning rate (R) = $5/hr

Answer:
28 miles in 7 minutes, 240 miles in an hour
Step-by-step explanation:
We can first simplify the rate to miles per minute. Since the plane goes 12 miles in 3 minutes, we can divide it by 3 to find how much it travels in one minute. 12 divided by 3 is 4 and 3 divided by 3 is 1
The plane travels 4 miles a minute
To find how much it travels in 7 minutes, multiply by 7
4x7 is 28
28 miles in 7 minutes
To find an hour, multiply by 60
4x60= 240
240 miles in an hour
88 tenths. In each case 8.8 is 88 tenths
Answer:
95% CI = ( 8.024 , 8.936 )
Step-by-step explanation:
Developing the exercise for a normal distribution then we have to calculate the degrees of freedom,

Where n, is our sample.
So in the table,
t = 2.1604


<em>**Assumptions:</em>
<em>Population is normal distributed</em>
