Answer: False

Step-by-step explanation:

All whole numbers can be decomposed into prime factors. For the number 40, the prime factorization would be 2 * 2 * 2*5. Since all 4 of those numbers are prime numbers, the answer is false.

False, because the number 40 is a composite number, those that cannot be broken down are called Prime Numbers.

Prime numbers are numbers that are used to decompose any number, but prime numbers cannot be decomposed, since they only have two Divisors, which are 1 and itself.

Lady_Fox [76]

Answer:

The mean is 11.5 minutes and the standard deviation is of 6.64 minutes

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The mean is:

M = \frac{a+b}{2}

The standard deviation is:

S = \sqrt{\frac{(b-a)^{2}}{12}}

Arrival time of 9:18 am and a late arrival time of 9:41 am.

9:41 is 23 minutes from 9:18. So the time is uniformily distributed between 0 and 23 minutes, so a = 0, b = 23.

Mean:

M = \frac{a+b}{2} = \frac{0+23}{2} = 11.5

Standard deviation:

S = \sqrt{\frac{(b-a)^{2}}{12}} = \sqrt{\frac{(23 - 0)^{2}}{12}} = 6.64

The mean is 11.5 minutes and the standard deviation is of 6.64 minutes

Find the ninth term of the
pantera1 [17]

Answer:

a_{9}=0.00015241579

Step-by-step explanation:

Use the formula for geometric sequences:

a_{n}=a_{1}r^{n-1}

Substitute 1 in for a_{1}, -1/3 in for r, and 9 in for n

a_{9}=(1)(-1/3^9-1)

a_{9}=(1)(-1/3^8)

a_{9}=(1)(0.00015241579)

a_{9}=0.00015241579

Hope this helps! :)
