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:

The monthly interest rate is 0.75%
<u>Step-by-step explanation:</u>
The rate of interest= 9%
Total time = 6years
Interest rate per month = 9/12
= 0.75%
Monthly payment =cost of the car + 0.75% of cost of car
Interest per month is 0.75%
It's easy it's just 62×9 it equals 558
Answer:
0.318
Step-by-step explanation:
on division with 10, the value reduces.... decimal moves forward
on multiplication, the value increases decimal moves backward....
eg: 3.18 x 10 = 31.8
The first square has side lengths of 4 units(because the square root of 16 is 4). The second square has side lengths of 8 units. The third square has side lengths of 12 units. As you can tell, the side lengths increase by 4. So the fourth square will have side lengths of 16 units, and the fifth square will have side lengths of 20 units. The question wants the perimeter, so the answer is 20*4(sum of 4 sides of equal lengths) which is 80 units.
