You would multiply 18 machines x 16" for a total of 288 inches. You would then divide by 36 because there are 36" (or 3 feet) in a yard. The answer is 8 yards of tubing.
Hello!
your answer is: A. 8
the other answers contain equations that do not result in 8
B is equal to 36
C is equal to 40,320
I hope this helps, and have a nice day!
Probability of an adult who needs correction = 82% or 0.82
So, probability of an adult who does not needs correction = 1 - 0.82 = 0.18
If 12 adults are randomly selected, the probability that at least 11 of them need correction for their eyesight is:
12C11
+ 12C12
= 12*0.11*0.18 + 1*0.09*1
= 0.238+0.09
= 0.328 or 0.33
And, yes, 11 is significantly a high number of adults requiring eyesight correction.
4, because 4 to the power of two means you multiply that number by itself so 4x4=16. And 16-16=0 <span />
5/8=10/16 sooooooo 10/16-3/16=7/16
