Answer:

119 4/7

Step-by-step explanation:

Perimeter is all of the lengths of the sides added together. I started by adding all of the whole numbers:

35+10+12+15+24+12+10=118

Then I added the fractions (after making the denominators equal by multiplying the 3/7, 1/7, 2/7 all by 2)

6/14+2/14+4/14+3/14+1/14+4/14+2/14= 22/14

Then I subtracted 14 from 22 to take out our whole number (which would be 14/14 or 1), and see that we are left with 8.

This means that our answer is 119 8/14 or 119 4/7

What is the equation in standard form of the line shown on the graph

dybincka [34]

Answer:

Step-by-step explanation:

We take two points (0,-3) and (4,0)

eq. of line thro' two points is y-y1=m(x-x1)

m=(y2-y1)/(x2-x1)=(0+3)/(4-0)=3/4

Reqd. eq . is y-(-3)=3/4(x-0)

or y=3/4(x)-3

Let ˆθ be a statistic that is normally distributed with mean θ and standard error σθˆ. Show that 100(1 − α)% confidence interval

qaws [65]

Answer:

$\hat{\theta} \pm z_{\frac{\alpha}{2}}(\hat{\sigma_{\theta}})$

Step-by-step explanation:

We are given the following in the question:

$\hat{\theta}$ is distributed normally.

Mean = $\hat{\theta}$

Standard error = $\hat{\sigma_{\theta}}$

Significance level = $\alpha$

Thus, the confidence percentage is

$100(1 - \alpha)\%$

Confidence interval:

$\mu \pm z_{critical}\frac{\sigma}{\sqrt{n}}$

$\mu \pm z_{critical}(\text{Standard error})$

$z_{critical}\text{ at}~\alpha = z_{\frac{\alpha}{2}}$

Putting the values, we get,

$\hat{\theta} \pm z_{\frac{\alpha}{2}}(\hat{\sigma_{\theta}})$

which is the required confidence interval.

Does the point (-4,-14) lie on the line<br>y = 2x - 6?

mel-nik [20]

Answer:

Substitute the coordinate of point into line equation, we have:

2 x (-4) - 6 = -14

=> The point lies on the line

Hope this helps!
