Step-by-step Proportion:

2 = X

3 = 12

Cross multiply:

2 x 12 = 24

3 x X = 3x

24 = 3x

Simplify:

8 = x

Hope it helps!

Answer:

A proportion is simply a statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d. The following proportion is read as "twenty is to twenty-five as four is to five."

Step-by-step explanation:

The triangle is isosceles (XZ = YZ), so the base angles are congruent. The total of all three angles in the triangle is 180 degrees, so subtracting out 52 leaves 128 degrees for the two base angles together. Each base angles measures half of that, so $m\angle 1 = 64^\circ$ , code E.

Look at vertex Y. The big angle there also measures 64 degrees.

$m\angle 2 + 31^\circ =64^\circ\\m\angle 2= 64^\circ - 31^\circ = 33^\circ \text{ (code B)}$

Angle 3 is a vertical angle with the 88 degree angle, so its measure is also 88 degrees (code G).

Finally, angle 4 is an exterior angle in the small triangle that contains angles 2 and 3. In that triangle, angles 2 and 3 are the remote interior angles.

$m\angle 4 = m\angle 2 + m\angle 3\\m\angle 4 = 33^\circ + 88^\circ = 121^\circ \text{ (code A)}$

You start at (8, 1). You move right 1 unit and left 3 units. Where do you end?

Do students that are "Greek" (those who belong to a sorority/fraternity) have a tendency to be more involved in student governme

defon

Answer:

Step-by-step explanation:

Greek students will represent p1 (proportion 1)

Non-Greek students will represent p2

If we were to conduct a hypothesis test for this data, we would use a test for the difference of 2 proportions. The hypothesis for this test would be as follows...

H0: p1 - p2 = 0

Ha: p1 - p2 > 0

The reason the alternate hypothesis is greater than 0 is because the question claims that the proportion of greek students (p1) is greater than the proportion of non-greek students (p2). So p2 is smaller than p1. We are subtracting a smaller number from a larger number. That will always result in a positive number.

Solve the equation using the substitution u = y/x. When u = y/x is substituted into the equation, the equation becomes separable

Answer:

$\frac{u^2+3}{-u^3+u^2-2u}u'=\frac{1}{x}$
