Given :
Weekly salary , S = $150.
Commission per car , C = $325.
To Find :
The the equation that models the weekly salary of a car salesman.
Solution :
We know it is a quadratic equation :
Let , the equation is , y = mx + c
Here, x is number of car sold in a week.
For x = 0 ( He will not get commission)
So , Salary is $150 = c .
For x = 1
Salary is $( 150 + 325 ) = $475 = m(1) + c
Therefore , m = $325 and c = $150.
Required linear equation is y = 325x + 150.
Hence, this is the required solution.
Hi there!
To find the perpendicular slope you need to flip the fraction and change the sign. So 1/2=2/1 and tge original slope was positive, so the slope is -2. Now you sub in the point (-7,-4) in for x and y in the formula y=mx+b and solve for b (sub in 2 for m as well)
Y=mx+b
-4=-2*-7+b
-4=14+b
-4-14=b
B=-18
The equation is y=-2x-18
Hope this helps!

Answer:
See below...
Step-by-step explanation:
Theoretical probability is the probability that something should happen based on the beginning conditions. Such as having a jar of 30 marbles with 5 being blue. The probability of pulling out a blue marble when selecting 1 marble is
5/30, or 1/6. Theoretically you should pull one blue marble out every 6 times you pull a marble out.
This isn't guaranteed to happen though, that's where experimental probability comes form.
Experimental probability is the number of desired outcomes achieved, divided by the total number of outcomes. This is based on what actually happened. Say you selected a marble, and put it back 10 times, recording the color each time and you got 2 blue marbles. Your experimental probability is
2/10, or 1/5, which doesn't match the theoretical probability. The more times this experiment is conducted, the closer your result will be to the theoretical probability
