Step-by-step explanation:
steps are in picture
3y+x=12 in slope intercept form is y=-1/3+4
Answer:
The standard deviation reduces when sample size (n) increases
Step-by-step explanation:
From the above information given, we have that mean = 75.5
Standard deviation = 3.5
But Standard deviation = √summation (x-u)/n
This simply implies that when sample (n) is increased there would be a reduction in the standard deviate.
Answer:
$25.44
Step-by-step explanation:
First, find the original cost of the binders:
5(8)
= $40
Find the cost with the 40% discount:
40(0.6)
= $24
Find the cost with the 6% sales tax:
24(1.06)
= $25.44
So, the total cost of the binders was $25.44
