Answer:
D. y-5 = 3(x+1)
Step-by-step explanation:
Slope of the perpendicular line is 3.
Slope intercept form is,
y-5 = 3 (x-(-1))
y-5 = 3(x+1)
Answer:
y = 3/4x -2
Step-by-step explanation:
Rise 3, run 4. Slope 3/4. Y intercept at -2.
Answer: 2.508
Step-by-step explanation:
As per give , we have
Sample size : n= 23
Degree of freedom : df= n-1=22
significance level :
Since , the sample size is small (n<30) and population standard deviation is unknown.
So , we use t-test.
For confidence interval , we find two-tailed test value.
Critical t-value :
[using students's t-critical value table]
Hence, the critical value that should be used in constructing the confidence interval = 2.508
Answer: D)
Step-by-step explanation: It starts around the middle of the Y axis which means the fixed price that they were talking about. Then the arrow keeps going which indicates the hourly rate.
