The weight of a small Starbucks coffee is a normally distributed random variable with a mean of 390 grams and a standard deviation of 9 grams. Find the weight that corresponds to each event. (Use Excel or Appendix C to calculate the z-value. Round your final answers to 2 decimal places.) a. Highest 10 percent
b. Middle 50 percent to
c. Highest 80 percent
d. Lowest 10 percent

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7

he answer is x=1x3 because x=1 to x=3

i belive the biggest ratio would be 18: correct me if im wrong

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
