Answer:
Step-by-step explanation:
Given that a large trucking company wants to estimate the proportion of its tracker truck population with refrigerated carrier capacity.
Sample size n =200
Sample proportion p = 0.30
q = 1-p =0.70
Std error =
For 90% confidence interval, Z critical = ±1.645
Hence margin of error = ±1.645(0.0324) =±0.0533
Confidence interval = 0.30±0.0533
= (0.2467, 0.3533)
s=3f-24
add 24 to each side
s+24 =3f
divide by 3
(s+24)/3 = f
Answer: f=(s+24)/3 or 1/3 s +8
Thus, the rate of change per gallon of gas is 60 miles per gallon.
A motorcycle consumes 5 gallons of gas for 300 miles and 7 gallons for 420 miles.
<h3>What is
rate of change?</h3>
Rate of change is defined as the change in value with rest to the time is called rate of change.
Now,
Rate of change = Difference B/w volume (i.e. in gallons) /difference in miles
= 420-300/7-2
= 60 gallons/mile
Thus, The required rate of change per gallon of gas is 60 miles per gallon.
