Answer:

z-score = 2.

Step-by-step explanation:

In the diagram below of triangle MNPMNP, QQ is a midpoint of \overline{MN}
trasher [3.6K]

Answer:

Given that MNP is a triangle. Q is the midpoint of MN and R is the midpoint of NP.

The length of QR is 4x -11 and the length of MP is 9x - 29.

We need to determine the measure of MP.

Value of x:

The value of x can be determined using the triangle midsegment theore

Applying the theorem, we have;

Substituting the lengths, we get;

Subtracting both sides by 8x, we have;

Adding both sides of the equation by 29, we get;Thus, the value of x is 7.

Measure of MP:

The measure of MP can be determined by substituting x = 7 in the length of MP.

Thus, we have;

Thus, the measure of MP is 34.

yKpoI14uk [10]

Answer:

TO = 5

Step-by-step explanation:

QUAD:STOP = 3:1

Therefore UA:TO = 3:1

If UA = 15, then TO = 15/3 = 5, or

UA:TO = 15:5 = 3:1
