QveST [7]3 years ago
6 0

Answer:

F(x) = |x|

And we need to apply some transformations. The first part is hift 8 units left. And we need to do this:

F(x) = |x+8|

Then we need to apply the second transformation Shift 3 units down. and we can do this:

F(x) = |x+8|-3

Step-by-step explanation:

For this case we have the following function given:

F(x) = |x|

And we need to apply some transformations. The first part is hift 8 units left. And we need to do this:

F(x) = |x+8|

Then we need to apply the second transformation Shift 3 units down. and we can do this:

F(x) = |x+8|-3

Len [333]

Answer:

If im not wrong, the correct answer is 752.4cm cube

Step-by-step explanation:

First, we find volume of hemisphere, then find the volume of the cone, once we get those, we add them together and find our final answer. I hope this helps :)

In order to estimate the average time spent on the computer terminals per student at a local university, data were collected for
Setler [38]

Answer:

7) d)

standard error of the mean of one sample of 'n' observation = 0.20

8) a)

The margin of Error = 0.392

9) d

The 95% of confidence intervals are (8.61 , 9.39)

Step-by-step explanation:

7)

solution:-

The Given data sample size 'n' = 81

Given Population standard deviation 'σ' = 1.8 hours

The standard error of the mean of one sample of 'n' observation is

Standard error (SE)

                               = \frac{S.D}{\sqrt{n} }  

                               = σ / √n

                               = \frac{1.8}{\sqrt{81} } =0.2

standard error of the mean of one sample of 'n' observation = 0.20

8)

Solution:-

The Given data sample size 'n' = 81

Given Population standard deviation 'σ' = 1.8 hours

Given the probability is 0.95

The z- score = 1.96 at 0.05 level of significance.

The margin of Error   =  \frac{z_{0.95} S.D}{\sqrt{n} }

                                   = \frac{1.96 (S.D)}{\sqrt{n} }

                                   = \frac{1.96 (1.8)}{\sqrt{81} }

                                   = 0.392

The margin of Error = 0.392

9)

Solution:-

<u>The 95% of confidence intervals are </u>

<u></u>(x^{-} - 1.96\frac{S.D}{\sqrt{n} } , x^{-} + 1.96\frac{S.D}{\sqrt{n} } )<u></u>

<u></u>(9 - 1.96\frac{1.8}{\sqrt{81} } , 9+ 1.96\frac{1.8}{\sqrt{81} } )<u></u>

(9 - 0.392 , (9 + 0.392)

(8.609 , 9.392)

<u>The 95% of confidence intervals are </u>(8.61 , 9.39)
