C= 2000 + 3(2500)
C= 2000 + 7,500
C= $9,500
A. A=1/2(6x8)= 24
B=6+15+10=31
SA=2(24)+31(8)=296in.
b.V=1/2(8)(6)(15)=360in.
c. I'm not sure.
When X = -9 Y = 1 you can find this by going to -9 on the x axis and finding where the line is there
3% as a decimal is 0.03 and I think 3% as a fraction in simplest form is 3/100
The <em><u>correct answer</u></em> is:
0.0764
Explanation:
We will use a z-score to answer this. The formula for a z-score is
, where μ is the mean and σ is the standard deviation. Using our information in this problem, we have

Using a z-table, we look up the z-score 1.43. The area under the curve to the left of, or less than, this value is 0.9236. This means the probability that the time is greater than this is 1-0.9236 = 0.0764.
