Answer:
0.9953, 3.3629<x<4.0371
Step-by-step explanation:
Given that slader the internal revenue service claims it takes an average of 3.7 hours to complete a 1040 tax form, assuming th4e time to complete the form is normally distributed witha standard devait of the 30 minutes:
If X represents the time to complete then
X is N(3.7, 0.5) (we convert into uniform units in hours)
a) percent of people would you expect to complete the form in less than 5 hours
=
b) P(b<x<c) = 0.50
we find that here
c = 4.0371 and
b = 3.3629
Interval would be

1) the slope of the line is where x=0 and the y coordinate is 1
2) plant 2 of the coordinate pairs on the graph, then from there find where the y intercept passes through where x=0
3) slope form is y=mx+b
y=-3x+9 if you use (-3,9)
plant it on the graph and then write a brief explanation
Answer:
THIS IS TOO CONFUSING
Step-by-step explanation:
Answer:
Cost = 17.08
Step-by-step explanation:
The cost is 4.88 per pound.
We buy 3.5 pounds
Cost = number of pounds * cost per pound
Cost = 3.5 * 4.88
Cost = 17.08
