The amount of time that Alyse procrastinates after school follows anormal distribution. Alyse procrastinates less than 10 minutes 10% of thetime and she procrastinates more than 60 minutes 60% of the time. The provided normal distribution has marks at the mean, as well as 1, 2, and 3 standard deviations away from the mean. Estimate and label the location of the boundary and shade the area corresponding to eacl of the statements: a. Alyse procrastinates less than 10 minutes 10% Of the time.
b. She procrastinates more than 60 minutes 60% Of the time.

cut 138 centimeters off

step-by-step explanation:

250-112 = 138

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
