Answer: HOPE THIS HELPED! :D
5 x 15 = 75
Step-by-step explanation:
15 is 3x 5
and product do 3x15 is 75
so answer would be
5 & 15
Answer:

And we can solve this using the following z score formula:

And if we use this formula we got:

So we can find this probability equivalently like this:

Step-by-step explanation:
Previous concepts
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".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the heights of a population, and for this case we know the distribution for X is given by:
Where
and
We select n =100. Since the distribution for X is normal then we know that the distribution for the sample mean
is given by:
We want this probability:

And we can solve this using the following z score formula:

And if we use this formula we got:

So we can find this probability equivalently like this:

At x=2, y=4
At x=4, y=16
So the total change in y from x=2 to x=4 is 16-4=12
And since average rate of change = total change in y divided by total change in x within the same period, therefore the answer is 12/2 = 6

Answer:
1960 cm^2
Step-by-step explanation:
Surface area:
Area of cross section x 2 = 1/2 x 20 x 21 x 2 = 420 cm^2
Area of slope = 29 x 22 = 638cm^2
Area of base = 22 x 20 = 440cm^2
Area of back = 21 x 22 = 462cm^2
Total Surface area = 462+440+638+420 = 1960cm^2
Hope this helps
Answer:
The correct answer for this problem is the 2nd one because all you have to do is count how far each one is from -1 and -2
