Answer:

1/3

Step-by-step explanation:

Figure A is

-the initial one and

-is bigger

so the scale factor is less then 1 and the figure A was shrunk to figure B

If we compare the sides of the triangles we see that the green triangle was shrunk by a k= 1/3 factor into the blue triangle.

Blue triangle is 3 times smaller than green triangle.

The side lengths from Figure A to Figure B grow by a factor of 1.5—each side length from A to B is 1.5 times as long. So, the scale factor from Figure A to Figure B is 1.5.

A computer hard drive contains a circular disk with diameter 2.5 inches and spins at a rate of 7200 RPM (revolutions per minute)

PIT_PIT [208]

Now to solve this problem, all we have to remember is the formula for calculating the linear speed given the radial speed, that is:

v = r w

where,

v = is the linear velocity or linear speed

r = is the radius of the circular disk = (1 / 2) diameter = (1/ 2) (2.5 inches) = 1.25 inches

w = is the radial velocity (must be in rad per time) = 7200 rev per minute

Calculating for v:

v = 1.25 inches (7200 rev per minute) (2 π rad / 1 rev)

v = 56,548.67 inches / minute

Converting to miles per hour:

v = 56,548.67 inches / minute (1 mile / 63360 inches) (60 min / hour)

A psychology professor assigns letter grades on a test according to the following scheme. A: Top 10% scores, B: Scores below 10%

stich3 [128]

Answer:

The numerical limits for a D grade is between 57 and 64.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question:

$\mu = 71.5, \sigma = 9.5$
