1. Answer: given: an average of 28 pounds
a.
Find z values corresponding to 27 and 31:
z=%2827-28%29%2F2=-1%2F2=-0.5
z=%2831-28%29%2F2=3%2F2=1.5
Find the area between z+=+-0.5 and z=+1.5
Table E gives us an area of 0.9332-0.30=0.6247=> The probability is 62.47%
b.
Find z values corresponding to 30.2
z=%2830.2-28%29%2F2=2.2%2F2=1.1 Find the area to the right of z+=1.1
it gives you an area of 0.1357=> The probability is 13.57%
Write and solve an equation of ratios, as follows:
32 fl oz 60 min
----------- = ------------
x 135 min
Then 60x = (32)(135) = 4320, and x = 72 oz.
damron should drink 72 fl. oz. of water if he rides 135 min.
Answer:
5
Step-by-step explanation:
It's a right triangle so 7x + 11x = 90
Solve for x
7x + 11x = 90
18x = 90
x = 5
