The diagram below represents three groups of students: S (blue and green): The set of students who took a Spanish class. T (green and orange): The set of students who traveled to a Spanish-speaking country. D (red and orange): The set of students who did not take a Spanish class. Each block represents one student. If a student did not travel to a Spanish-speaking country, how many times more likely is it that the student did not take Spanish? It is 22 times as likely. It is 9 times as likely. It is 4.5 times as likely. It is 2.2 times as likely.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

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

it is 28 degrees colder in detroit than philadelphia.

step-by-step explanation:

what number adds to 21

-7 + ? = 21

-7 + 28 = 21
