Answer:
The slope of the line is 1/2
Answer:
y= -4x+22
Step-by-step explanation:
slope= -4
-6=-4(7)+b
-4x7=-28
-6=-28+b
28-6=22
so the equation would be y= -4x+22
b=y-intercept
mx=slope multiplied by x
In one year, $ 9,000 with a profit of 7.75%, is $ 697.5
697.5 × 18 = 12555
After 18 years old, it is $ 15,222
Answer:
E(X ¯)=210,000.
Step-by-step explanation:
A sampling distribution for samples of size n=49 from a population with means μ=210,000 and standard deviation σ=35,000, has the following means anda standard deviation:

If X ¯ is the mean sales price of the sample, it will have a mean value of E(X ¯)=210,000.
