The probability that x equals 19.62 is 0
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean and standard deviation
, the z-score of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
In the normal probability distribution, the probability of an exact value, that is, P(X = x) is 0. Thus, the probability that x equals 19.62 is 0
Answer:
The first number is <u>18</u> and the second number is <u>27</u>.
Step-by-step explanation:
Given:
A first number is nine less than a second.
The sum of the numbers is 45.
Now, to find the numbers.
Let the second number be
And the first number be
The sum of the both numbers is 45.
According to question:
⇒
⇒
<em>Adding both sides by 9 we get:</em>
⇒
<em>Dividing both sides by 2 we get:</em>
⇒
<u><em>The second number = 27</em></u>.
Now, to get the first number we put the value of :
Therefore, the first number is 18 and the second number is 27.
Step-by-step explanation:
- a = 2
- b = 3
- c = 5
Therefore, 32/243 is the answer.
