Answer:
see below
Step-by-step explanation:
Number of workers (x) 0 10 20 30 40 50 60 70 80 90
Number of units (y) 2 52 102 152 202 252 302 352 402 452
Part A
There is a correlation
For each increase of 10 in x, there is an increase of 50 in y
10 10 10 10 10 10 10 10 10
Number of workers (x) 0 10 20 30 40 50 60 70 80 90
Number of units (y) 2 52 102 152 202 252 302 352 402 452
50 50 50 50 50 50 50 50 50
Part B
m = (y2-y1)/(x2-x1)
= (452-402) /( 90-80) = 50/10 = 5
The y intercept is the value of y when x =0
The y intercept is 2
The slope intercept form of the the line is
y = mx+b
y = 5x+2
PartC
The y intercept is that we start with 2 of the units and for each worker gained, they will make 5 units per day
Answer:
A multiplication pattern is created when you are multiplying the same number by the same number and go adding up!!!XD
Hope this helped!!!XD
Also can I get brainliest please?
Patients who visit a clinic for the first time are asked to answer 15 questions about their health history.
Survey
A researcher randomly chooses 20 patients who come to the clinic with the flu and gives them an experimental drug. A randomly chosen group of 20 patients who come in with the flu receive a placebo.
Experiment
A doctor at the clinic asks patients who come in with a headache how many hours of sleep they get on a typical night.
Observational Study
So first, you need to identify the parts of this equation.
3x is the slope of the line, which is .
-5 is the y-intercept. or the part of the line that touches the y-axis.
The first thing you want to do is plot the y-intercept. SO, go to the y-axis and find -5. Plot your point there.
Now, use the slope to find your next plot. Since slope is , you go up three, and over to the right one.
Now, draw a line connecting the dots. Your slope should be positive and look like > /
