I think A which is 4in but not sure
Answer:
3/16
Step-by-step explanation:
1. you convert 1/4 into 16ths and you get 4/16
2. 4/16 - 1/16= 3/16
The center is (-1, -2) and the radius of the circle is 5.
<h3>What is the equation of a circle?</h3>
The circle equation formula refers to the equation of a circle which represents the center-radius form of the circle.
A circle can be represented as;

Where; h and k are the center of the circle r is the radius of the circle.
The given equation of the circle is;

Comparing both the equations;

Hence, the center is (-1, -2) and the radius of the circle is 5.

Answer:
6x + 9 = 27
-9 -9
6x = 18 Now divide both sides by 6
/6 /6 so the answer is 3
Step-by-step explanation:
Answer:
And we can find this probability with this difference:
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 amount of cofee shops of a population, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability with this difference:
