Answer:
1.4 inches.
Step-by-step explanation:
Given that the length of the pool = 200 ft.
Scale factor = 1725.
As,
So,
By using the given values, we have
{Scaled length}
As 1 foot = 12 inch,
So, scaled length = 0.116 x 12 = 1.4 inches.
Hence, the scale length of the model = 1.4 inches.
39
sum of 2 digit no. can be
3+9
4+8
5+7
6+6 (which cannot be the ans since interchanging the digits would give 0 difference)
so,
93-39=54
84-48=36
75-57=18
so 93 is the reversed no. and 39 is the original no.
The correct option is (B).24 miles.
Z-score is basically another term for the specific number of standard deviations. I suppose we can assume normality here, even though it isn't given, so I'd make a rough sketch.
Otherwise, just use the basic formula:
Given that,
(statistic for a mean) and (statistic for a standard deviation).
Since z-score must be Less than 1.5, So
I just used normal cdf and got .
Hence the correct option is (B).24 miles.
