Answer:
- rate of change: $8 per hour; the per-hour rental charge
- initial value: $75; the deposit on the machine
Step-by-step explanation:
The cost to rent the machine is given as ...
total cost = deposit + ($8 /hour)×(number of hours)
The cost for 5 hours is given ans $115, so we have ...
115 = deposit + 8(5)
75 = deposit . . . . . . . . subtract 40
__
The "rate of change" is given as $8 per hour, the hourly rental charge.
The "initial value" is called <em>the deposit</em>. It is found to be $75.
Answer:
Option A)
Confidence interval decreases
Step-by-step explanation:
If we increase the sample size, then,
- The standard error of the interval decrease.
- If the standard error increase, the margin of error of the interval decrease.
- If the margin of error decreases, the width of the confidence level decreases, hence, the confidence interval become narrower.
Thus, the correct answer is
Option A)
Confidence interval decreases
Slope= -3/2
Y-intercept=33/2
Answer:
3 /4 x+ 1 /2 one-half more than three-fourths of a number
3/ 4 − 1 /2 x three-fourths minus one-half of a number
3/ 4 −(x+ 1/ 2 ) three-fourths minus the sum of a number and one-half
