Part A : The diagram shows a line of best fit with a positive correlation.As the amount of guests increases the amount of pizzas increase supporting the positive correlation.
Part B : I haven't gotta clue sorry
0.2 is 10 times as much of... well you must do the opposite of what it says... well, times means to multiply and the opposite of multiplying is dividing, 0.2 divided by 10 is 0.02
So... 0.2 is 10 times as much as 0.02
Now, 0.2 is 1/10 of... well this question shows to divide and we must do the opposite, which is... multiplying 0.2 times 10 is 2
So... 0.2 is 1/10 of 2
Answer:
The constant charge for each minute used is $50
Step-by-step explanation:
In order to solve this problem we will need to set two variables up. In this case:
F = constant Fee
R = rate per minute used
So the cost for the month of January is calculated like this:
F+300R=68
and the cost for February is calculated like this:
F+275R=66.5
So no we have a system of equations we can solve simultaneously. This can be solved by using different methods, elimination, substitution, graphically or by using matrices. I will solve this by substitution.
So let's solve the first equation for R:

and let's substitute this first equation into the second equation:

and now we can solve this for F:

We can multiply both sides by 12 so we get:
12F+11(68-F)=798
12F+748-11F=798
F= $50
Answer:

Step-by-step explanation:
Since
is the same as
and
, then we know that the side opposite to the angle
is 4 units and the hypotenuse is 5 units.
Because
, then we have to find the adjacent side to the angle
using the Pythagorean Theorem:

Therefore, since the adjacent side is 3 units, then 
The answer to that question is 7781
