Answer:
y=5
Step-by-step explanation:
If it is perpendicular to the y-axis, that means it is a horizontal line so the slope m=0.
Use the equation
y-y=m(x-x)
y-5=0(x-(-4))
y-5=0
y=5
Answer:
e=142,900+1.24q, where:
e are the total expenses
q is the quantity produced.
Step-by-step explanation:
With the information provided, you can say that the total expense would be equal to the result of adding up the fixed expenses plus the variable expenses. These variable expenses would be equal to the expenses per mini-widgets for the quantity produced, which you can express as:
e=142,900+1.24q, where:
e is the total expense
q is the quantity produced.
Answer:
Step-by-step explanation:
Given that researchers wondered whether the size of a person's brain was related to the individual's mental capacity
They selected a sample of 5 females and 5 males and measured their MRI counts and IQ scores.
The data is reported to the right. Complete parts (a) through (d) below.
We want scatter plot for IQ vs MRI in general.
So we group data into two columns X for MRI and Y for IQ and draw scatter plot
MRI IQ
816932 133
1001121 140
833868 132
856472 140
866662 130
1038436 139
1079550 141
924059 136
a) Scatter plot is attached as a file
b) correlation coefficient = Cov (x,y)/S_x S_y = 0.729889
B) Yes, MRI count and IQ are linearly related since the linear correlation coefficient is _____.0.729889 >0.5 and near to 1 than to 0
There is a positive moderate correlation between x and y (linear)
