2. A study of the ages of motorcyclists killed in crashes analyzed a random selection of 150 drivers. The mean age for drivers killed in the sample was 37.1 years (data from the
Insurance Institute for Highway Safety). Assuming that o = 12.0 years, construct a 95%
confidence interval for the mean age of all motorcyclists killed in crashes.

which expression represents the approximate length of bc?

step-by-step explanation:

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
