Find QD if QB=21 and PC=11
alexdok [17]

Answer:

The answer to your question is: 21

Step-by-step explanation:

Data

AB = BC = CD

BQ = 21

QD = ?

PC = 11

Process

Here there are 2 triangles

ΔQCB and ΔQCD

These triangles share one side QC

And one side measures the same BC = CD

And the ∠ BCQ = ∠ DCQ

Then these triangles are congruents  SAS

if QB = 21 then QD = 21

For a population with µ = 100 and σ = 20, what is the X value corresponding to z = -0.75?​
Savatey [412]

The X value corresponding to z = -0.75 will be 85. Then the correct option is A.

<h3>What is the z-score?</h3>

The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.

The z-score is given as

z = (x - μ) / σ

Where μ is the mean, σ is the standard deviation, and x is the sample.

For a population with µ = 100 and σ = 20.

Then the X value corresponding to z = -0.75 will be

-0.75 = (x - 100) / 20

   -15 = x - 100

      x = 85

Then the correct option is A.

More about the z-score link is given below.
