Answer:

A=  87   B= 93

Step-by-step explanation:

A

To answer this you must have some previous conventional information. All the internal angles of a triangle summed get 180º, that means:

3(x+2)+35+52=180

3x+6+35+52=180

3x+(6+35+52)=180

3x+ 93=180           organizing the values oh the correct sides we have

3x= 180-93 ( 93 comes to the right of the =signal and changes its value from + to -.

3x=87

x=87/3 ( / stands for divided by)

x=29

Bear in mind the equation from the angle: 3(x + 2)

3( 29+ 2 )= 3x29+6=

x=87

B:

Angle C =

3 (x + 2 )

3(29+2)=

87+6=93

JUST TO CHECK

A+B+C=180

35+52+93=180

180=180

Step-by-step explanation:

3(x+2) + 35 + 52 = 180 ( Angle sum property)

3x+ 6 + 87 = 180

3x + 93 = 180

3x = 180 - 93 = 87

x= 87/ 3

x = 29

∠C = 3 ( 29 + 2)

     =  3 x 31

     =  93

Suppose that the population of the scores of all high school seniors who took the SAT Math (SAT-M) test this year follows a Norm
Vlad1618 [11]

Answer:

Confidence =1-\alpha=1-0.01=0.99

And then the confidence level would be given by 99%

Step-by-step explanation:

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

Assuming the X follows a normal distribution

X \sim N(\mu, \sigma)

The distribution for the sample mean is given by:

\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}})

\bar x =512 represent the sample mean

\sigma=100 represent the population standard deviation

n= 100 sample size selected.

The confidence interval is given by this formula:

\bar X \pm z_{\alpha/2} \frac{\sigma}{\sqrt{n}}   (1)

The marginof error for this case is given by Me=25.76. And we know that the formula for the margin of error is given by:

Me=z_{\alpha/2} \frac{\sigma}{\sqrt{n}}

25.76=z_{\alpha/2} \frac{100}{\sqrt{100}}

And we can find the critical value z_{\alpha/2} like this:

z_{\alpha/2}=\frac{25.76(\sqrt{100})}{100}=2.576

And we know that on the right tail of the z score =2.576 we have \alpha/2 of the total area. We can find the area on the right of the z score using this excel code:

"=1-NORM.DIST(2.576,0,1,TRUE)" or using a table of the normal standard distribution, and we got 0.004998=\alpha/2, so then \alpha=0.00498*2=0.009995 \approx 0.01, and then we can find the confidence like this:

Confidence =1-\alpha=1-0.01=0.99

And then the confidence level would be given by 99%
