Answer:
y = 2x + 60
Step-by-step explanation:
Use the equation for a line: y = mx + b
Where
x and y are points on the graph
and m is the slope, and can be found by finding 
so the slope is 10/5 or 2, since the graph goes up by 10 and over by 5.
so plug into the equation, and you get y = 2x + b
Next, pick a point on the graph, and plug in the x and y coordinates,
for example:
(x,y) = (5,70)
so, 70 = 2(5) + b
then solve for b
60 = b
Then rewrite the equation
y = 2x + 60
Answer:
B and C
Step-by-step explanation:
4/7 = 0.57
2/3 > 4/7

x=the number of months
So the "7x" is the $7 per month, and the "10" is the $10 for each CD being ordered. It can't be more than 100, so the "less than or equal to" sign will be used.
Answer:
False
Step-by-step explanation:
Given that a researcher testing the effects of two treatments for anxiety computed a 95% confidence interval for the difference between the mean of treatment 1 and the mean of treatment 2
Also that confidence interval includes zero.
When confidence interval includes zero, we need not reject the null hypothesis since null hypothesis claims that difference =0
When confidence interval includes 0 it confirms that there is no difference and hence null hypothesis should be accepted.
