The area between z=0 and z=1 under the standard normal curve is ?

According to the Empirical Rule, 68% of data lies within 1 std. dev. of the mean. Thus, between z=0 and z=1 lie half of that, or 34%, of the data.

Using a calculator for a more precise

normalcdf(0,1) = 0.3413 (answer)

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

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
