Answer (Note: the bold are answers):
First question answer:
Point = (3,1)
Slope = 3
y = 3x + b
(1) = 3(3) + b
1 = 9 + b
1 - 9 = b
-8 = b
y = 3x - 8
The second question answer:
y = mx + b
Get two points:
(3,-7) and (4,-11)
m = -11 - (-7) / 4 - 3
m = -11 + 7 / 1
m = -4 / 1
m = -4
b = + 3
y = -4x + 3
If t=-3 (hopefully it does) then it's 6+-12/10. This is -6/10=-3/5
Answer:
(d)0.6
Step-by-step explanation:
(a)Frequency Distribution
(b)The relative frequency distribution.
(c)The cumulative frequency distribution.
(d)The proportion of customers needing an oil change who wait 9 minutes or less.
Proportion of customers needing an oil change who wait 9 minutes or less.
A horizontal line is one for which the value of y is the same for the entire length of the line. Therefore this type of line can be expressed as below:
Where "c" is a constant that changes the position of the line on the coordinate plane. If c is equal to 2, then we have a constant line that crosses the y-axis at the position 2 for example.
