Answer:
y = 11x
Step-by-step explanation:
We have two points so we can find the slope
(1,11) and (2,22)
m = (y2-y1)/ (x2-x1)
= (22-11)/(2-1)
= 11/1
The slope is 11
We can use the point slope form to get an equation
y-y1 = m(x-x1)
y-11 = 11(x-1)
Distribute the 11
y-11=11x -11
Add 11 to each side
y-11+11 = 11x-11+11
y = 11x

Hello!
In statistics, the relative frequency is the percentage/ proportion of times a determined event has occurred in a given experiment.
In this exercise you have to calculate the relative frequencies of the observed student's behavior, given that they received positive phone calls as an incentive and the observed student's behavior, given that they didn't receive positive phone calls as an incentive.
If "x" represent the number of observations for the category (Desirable behavior and Undesirable behavior) of interest and "n" the total number of observations in each row (Phone call and No phone call), you can calculate the relative frequencies as: f(x)= x/n
For the students that received the phone call:
n= 19 + 9= 28
The student showed desirable behavior: f(x)= 19 / 28= 0.678= 0.68
The student showed undesirable behavior: f(x)= 9 / 28= 0.678= 0.32
For the students that didn't receive the phone call:
n= 8 + 6= 14
The student showed desirable behavior: f(x)= 8 / 14= 0.678= 0.57
The student showed undesirable behavior: f(x)= 6 / 14= 0.678= 0.428= 0.43
I hope this helps!
The overall volume is the sum of the volume of a cylinder of height 5'9" and diameter 3'6", and a sphere of diameter 3'6" (two hemispheres = full sphere).
Volume of the cylinder = (area of the base) x (height) = pi * (diameter/2)^2 * 5.75ft = 3.1415 * (3.5ft/2)^2 * 5.75 ft = 55.32 ft^3
Volume of the sphere = 4/3 * pi * (3.5ft)^3 / 8 = 22.45 ft^3
Total volume = (Volume of cylinder) + (Volume of sphere) = (55.32 + 22.45) ft^3 = 77.77 ft^3
Answer:
4
Step-by-step explanation:
y = mx+b where m is slope so the slope is 4
Answer:
Step-by-step explanation:
so i cant actually see the picture on my school chromebook, but if only one x matches up to one y, then yes. multiple x's can go to a single y
