2007, the world's population reached 6.7 billion was increasing at a rate of
1.2% per year. Assume that the growth rate remains constant.
Generalize the expression for the world's population for t years since 2007 is:</span>

Answer is D. y = 1/2x + 3
Explanation
you are looking for “least steep” on the graph, so you are looking for the least amount of slope. Slope is the number next to x in the slope intercept y=mx+b.
1/2 on a graph would be 1 up and 2 to the right
The other three options would be 1 up 1 over, 2 up 1 over, 3 up 1 over, all having a steeper slope.
Answer:
H0 : μ = 18000
H1 : μ < 18000 - - - > Claim
Test value = - 3.578
Critical value = ±2.58
There is significant evidence to accept the claim that mean debt at graduation is less than $18000
Step-by-step explanation:
H0 : μ = 18000
H1 : μ < 18000
From the data:
Sample size, n = 30
Sample mean, x = 16298.37
The test statistic :
(16298.37 - 18000) ÷ (2605/sqrt(30))
−1701.63 / 475.60575
= - 3.578
The critical value :
Using the standard normal table;
Critical value at α = 0.01
Critical value = ±2.58
Decison region :
|test statistic | > |Critical value | ; reject H0
|3.578| > |2.58| ; We reject H0 and conclude that Mean debt at graduation is less than $18000
