Lelu [443]

Answer:

a.1.90 years

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.99}{2} = 0.005

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.005 = 0.995, so z = 2.575

Now, find the margin of error M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

In this question:

n = 25, \sigma = 3.8

So

M = 2.575*\frac{3.8}{\sqrt{25}} = 1.90

So the correct answer is:

a.1.90 years

Identify the coordinates that result when the point (−4, 5), is translated 8 units right and 3 units down. HELP ASAP!
pochemuha

Answer:

The answer is (4,2)

Step-by-step explanation:

in the point (-4,5) X=-4 AND Y=5

so if you move 8 units right, the X increases by 8(because the  the x axis is left and right) so X transform into 4= -4+8=4

With Y(the y axis is up and down) whe u go 3 units down un decrease the number so Y transforms into 2== 5-3=2

The new coordiantes are(4,2)
