1) $\angle 1=\angle 2$ , $AP=BP$ (given)

2) $\angle APD=\angle BPC$ (vertical angles are equal)

3) $\triangle ABD \cong \triangle BAC$ (ASA)

Graph the following piecewise function:

zhenek [66]

Check the picture below.

notice the solid circle at -4 and 3, since it includes those points.

also notice the dashed line, though the lines keeps on going those ways, is not included in the piece-wise, since it's not part fo the domain or constraints.

A sample of 5 strings of thread is randomly selected and the following thicknesses are measured in millimeters. Give a point est

xxTIMURxx [149]

Answer:

Point estimate for the population variance = 3.92 * $10^{-3}$ .

Step-by-step explanation:

We are given that a sample of 5 strings of thread is randomly selected and the following thicknesses are measured in millimeters ;

X X - $Xbar$ $(X-Xbar)^{2}$

1.13 1.13 - 1.188 = -0.058 3.364 * $10^{-3}$

1.15 1.15 - 1.188 = -0.038 1.444 * $10^{-3}$

1.24 1.24 - 1.188 = 0.052 2.704 * $10^{-3}$

1.27 1.27 - 1.188 = 0.082 6.724 * $10^{-3}$

$\sum (X-Xbar)^{2}$ = 0.01568

Firstly, Mean of above data, $Xbar$ = $\frac{\sum X}{n}$ = $\frac{1.15+1.24+1.15+1.27+1.13}{5}$ = 1.188

Point estimate of Population Variance = Sample variance

= $\frac{\sum (X-Xbar)^{2}}{n-1}$ = $\frac{0.01568}{4}$ = 3.92 * $10^{-3}$ .

Therefore, point estimate for the population variance = 3.92 * $10^{-3}$ .

In a survey, one out of five people named blue as their favorite color. Three out of ten named red. If 1,100 people were include

bagirrra123 [75]

1/5 = x/1100

5x = 1100
x = 1100 ÷ 5
x = 220

So 220 people named blue as fav.

3/10 = x/1100

3x = 1100
x = 1100 ÷ 3
x = 366.6666.... = 367

So 367 people chose red

Create an equation for the following scenario:

Ivanshal [37]

Hey there! I'm happy to help!

Sum means you add. Let's call our number n.

n+15

We double the whole thing.

2(n+15)

This is equal to something.

2(n+15)=

Difference means you subtract.

2(n+15)=n-6.

Have a wonderful day! :D
