The word "sum" means addition, so the question is asking you to add 914 and 878.

First you can add the hundreds, so 900 + 800 = 1,700
Then you can add the tens, so 10 + 70 = 80
And finally the units, so 4 + 8 = 12
When you add up all of these, you get your final answer as 1,792.

I hope this helps!

Answer:

The margin of error for the confidence interval for the population mean with a 98% confidence level is 2.88 miles per hour.

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:

$\alpha = \frac{1-0.98}{2} = 0.01$

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 $1-0.01 = 0.99$ , so $z = 2.326$

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.

Find the margin of error for the confidence interval for the population mean with a 98% confidence level.

$M = 2.326*\frac{7}{\sqrt{32}} = 2.88$

The margin of error for the confidence interval for the population mean with a 98% confidence level is 2.88 miles per hour.

If a building was placed at coordinates (-5,5), what would be the new coordinates if rotated 270° counterclockwise around the or

Brums [2.3K]

The rule for a 270° counterclockwise rotation is (x, y) ---> (y, -x).

So if you rotated (-5,5) 270° counterclockwise around the origin the new coordinates would be (-5,-5).

Hope this Helps!!

Experience shows that a ski lodge will be full (161 guests) if there is a heavy snow fall in December, while only partially full

Eva8 [605]

Answer:

Expected number of guests is 100.4.

Step-by-step explanation:

It is given that there are 161 guest if there is a heavy snow fall.

Also, the probability for a heavy snow fall is 0.40.

Therefore, P(X = 161) =0.4.

It is also given that there are 60 guests if there is a light snow fall.

The probability for a light snow fall is 1 - 0.4 = 0.6.

Therefore, P(X = 60) = 0.6.

Expected number of guests = (161)P(X = 161) + (60)P(X = 60)

= 161(0.4) + 60(0.6)

= 64.4 + 36

= 100.4
