Do you mean the top of the ladder and the top of the building? If so, it would be 9 feet<span />
Answer: First Option is correct.
Step-by-step explanation:
Since we have given that
Mean
= 70 inches
Standard deviation
= 3 inches
Average basket ball player
= 79 inches
Since it is normally distributed assume with 5% significance .
So, it becomes,

At 0.05 level of significance , 0.0013 = 0.13% of the adult male population is taller than the average basketball player .
Hence, First Option is correct.
Answer:
x=1 and y=4/5
Step-by-step explanation:
<u>Given system of equations</u>
3x+5y=7
5x+10y=13
<u />
<u>Multiply first equation by 2</u>
2(3x+5y)=2(7)
6x+10y=14
<u>Eliminate y-variable to get "x"</u>
6x+10y=14
<u>- 5x+10y=13</u>
x = 1
<u>Substitute x=1 into either equation and find "y"</u>
3x+5y=7
3(1)+5y=7
3+5y=7
5y=4
y=4/5
Therefore, x=1 and y=4/5
C = 11*(2*d) Try it and see that it fits every sample you have. Again this can be simplified to
C = 22 * d
