The solutions of the equation x² – 5x – 24 = 0 will be 8 and -3. Then the correct option is D.
<h3>What is a factorization?</h3>
It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The quadratic equation is given below.
x² – 5x – 24 = 0
Then the factor of the equation will be
x² – 5x – 24 = 0
x² – 8x + 3x – 24 = 0
x(x – 8) + 3(x – 8) = 0
(x – 8)(x + 3) = 0
x = 8, -3
Then the correct option is D.

Answer:
I think 14n + 9
Step-by-step explanation:
since she got her first email in 9 days and got her second email 14 days later, and it continues to appear every 14 days.
so I think it must be 14n + 9
Answer:
The answer would be 5x-18=13
Step-by-step explanation:
When given five times than a number, 5 would be multiplied by (x) since x can be any number. Less than 18 means subtract 18. Is equal to means an eual sign and the equation is equal to 13.
Using the normal distribution, it is found that the third quartile is of Q3 = 0.67, hence option B is correct.
In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:
- It 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, which is the percentile of X.
In this problem:
- The mean is of 0ºC, hence .
- The standard deviation is of 1ºC, hence .
The third quartile is X when Z has a p-value of 0.75, as , hence <u>X when Z = 0.67.</u>
