The definition of a prime number is one in which there are no factors other than 1 and itself. For example, 5 has no other factors other than 1 and 5 (itself).

The number 1 is not considered prime nor composite.So, even though it is a square (1²), it is not a prime number.

All square numbers have a square root that is neither 1 nor itself: 16 is the square of 4, 49 the square of 7, and so on.

Due to the fact that square numbers have factors other than 1 and itself, square numbers are not prime.

Hope this helps! :)

No because 9, for example, has 3 as its factors.

In Melanie's Styling Salon, the time to complete a simple haircut is normally distributed with a mean of 25 minutes and a standa
Triss [41]

Answer:

Longer than 27.7 minutes.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

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 pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

\mu = 25, \sigma = 4

The slowest quarter of customers will require longer than how many minutes (to the nearest tenth) for a simple haircut?

Longer than the 100 - 25 = 75th percentile of times, which is X when Z has a pvalue of 0.75. So X when Z = 0.675. So

Z = \frac{X - \mu}{\sigma}

0.675 = \frac{X - 25}{4}

X - 25 = 4*0.675

X = 27.7

So

Longer than 27.7 minutes.
