Answer:
the awnser is 0.000000564
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:
Answer:
-1/3
Step-by-step explanation:
Answer:
Find in Step by Step
Step-by-step explanation:
x-intercept = 26/-4 = 13/-2 = -6.50000
y-intercept = 26/1 = 26.00000
Slope = 8.000/2.000 = 4.000
Equation at the end of step 1 :
(y - 6) - 4 • (x + 5) = 0
Step 2 :
Equation at the end of step 2 :
y - 4x - 26 = 0
Step 3 :
Equation of a Straight Line
3.1 Solve y-4x-26 = 0
