Answer:
The Y intercept is the y value when x = 0
Step-by-step explanation:
On this graph the y interecept is going to be 0, in a y =mx + b equation, the y intercept will be your b value
Answer:

a) $4110
Step-by-step explanation:
Let x represent number of rain coats and C(x) represent total cost to produce new line of rain coats.
We have been given that the fixed costs of $570 to set up for production, and variable costs of $30 per jacket.
The cost of x jackets would be
.
The total cost of x jackets would be variable cost of x jackets plus fixed costs that is $570.
Therefore, the total cost of producing x rain coats would be
.
To find the total cost of producing 118 rain coats, we will substitute
in the above equation as:



Therefore, the total cost of producing 118 rain coats is $4110 and option 'a' is the correct choice.
The opposites of 1/3 and -7/12 is -1/3 and 7/12
Answer:
B. 97
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:

Now, we have to find z in the Ztable as such z has a pvalue of
.
So it is z with a pvalue of
, so 
Now, find M as such

In which
is the standard deviation of the population and n is the size of the sample.
How many students should be sampled to be within 1 drink of the population mean with 95% probability?
This is n when 
We know from preliminary studies that the standard deviation is around 5, so 





We round up, so the correct answer is:
B. 97
Answer:
10
Step-by-step explanation:
on the bottom it says 15
on the top 1 part of that same section is 5
15 -5 =10
