Answer:
And we can find this probability with this difference:
And in order to find these probabilities we can use tables for the normal standard distribution, excel or a calculator.
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 waiting time 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:
And in order to find these probabilities we can use tables for the normal standard distribution, excel or a calculator.
Answer:
15 tomatoes
Step-by-step explanation:
6:8 = 3:4
multiply each side by 5
= 15/20
so 15 tomatoes
<h2>
Explanation:</h2>
Here we have the following expression:

➷ Substitute -3 into g(x)
g(-3) = 2(-3) + 4
Solve:
g(x) = -2
Substitute this value into f(x)
f(-2) = 3(-2)^2
Solve:
f(-2) = 12
The answer is B. 12
