An English professor assigns letter grades on a test according to the following scheme. A: Top 14% of scores

B: Scores below the top 14% and above the bottom 57%
C: Scores below the top 43% and above the bottom 24%
D: Scores below the top 76% and above the bottom 8%
F: Bottom 8% of scores

Scores on the test are normally distributed with a mean of 69.6 and a standard deviation of 9. Find the numerical limits for a D grade. Round your answers to the nearest whole number, if necessary.

  57 to 63

Step-by-step explanation:

A suitable probability tool can tell you the limits.

  8% of scores will be below 56.95 ≈ 57

  76% of scores will be above 63.24 ≈ 63

Scores between 57 and 63 will get a D grade.

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .

they can both be solutions depends on the equation
