The prime factorization of 100 is 2 * 2 * 5 * 5. Using exponents, this number can also be written as 2^2 * 5^2.

Answer:

2 and 5

Step-by-step explanation:

Make a list of all of the factors of 100.

1, 100
2, 50
4, 25
5, 20
10, 10

A prime number has two factors, one and itself, so the prime numbers in this list are 2 and 5. 1 is not prime because it only has one factor, itself.

I think the answer is:
F^-1(x)= 1/(x+3)^2

Inverse mean the opposite or reverse

Hope this makes sense! :)

The life, in years, of a certain type of electrical switch has an exponential distribution with an average life β=44. If 100 o

Bond [772]

Answer:

0.9999

Step-by-step explanation:

Let X be the random variable that measures the time that a switch will survive.

If X has an exponential distribution with an average life β=44, then the probability that a switch will survive less than n years is given by

$\bf P(X$

So, the probability that a switch fails in the first year is

$\bf P(X$

Now we have 100 of these switches installed in different systems, and let Y be the random variable that measures the the probability that exactly k switches will fail in the first year.

Y can be modeled with a binomial distribution where the probability of “success” (failure of a switch) equals 0.0225 and

$\bf P(Y=k)=\binom{100}{k}(0.02247)^k(1-0.02247)^{100-k}$

where

$\bf \binom{100}{k}$ equals combinations of 100 taken k at a time.

The probability that at most 15 fail during the first year is

$\bf \sum_{k=0}^{15}\binom{100}{k}(0.02247)^k(1-0.02247)^{100-k}=0.9999$

Answer:

A. Her expenses are $25 per week.

Step-by-step explanation:

Using a linear function f(x) = mx + b, m= slope and b = y-intercept or initial value. With the values of the given function: E(x) = 7x - 25, we can determine that the overall earnings (E(x)) is based on a profit of $7 per door ('x') and that if Jessica is subtracting $25 from her earnings, that this must be the cost per week for her expenses. So, she would need to knock on a minimum of 4 doors each week in order to make a profit.
