okay since the first step is parenthesis, the next step would be exponents but you have none so you skip to multiplication, then you divide
divide is your answer
The answer is C. Explanation: The line isn’t a straight line, so it can’t be a linear line. Then, do the vertical line test to see if the line is a function (to do this, draw a vertical line through the graph, and see if it passes more than one point on the graph. If the vertical line passes any more than one point on the graph on any spot, it is not a function), and since the graph fails the vertical line test, it is not a function. Therefore, the answer is C.
Answer: Sample size would be 296.
Step-by-step explanation:
Since we have given that
Standard deviation = 4.8 hours
Margin of error = 0.65 hours
At 98% level of confidence, z = 2.33
So, It becomes,

Hence, sample size would be 296.
Answer: y= 1
This because the line has no slope so the equation really looks like this if we were to follow the y=mx+b format.
y=mx+b
y= 0x + b
because the number "0" multiplied by any value is still zero we can exlude that from the final equation of the line. In this case since m=0, the line is y=b.
b is the y intercept, or the value of y when x = 0.
So, because y=1 when x is 0, "b"= 1
y=b
y=1
