10(x-2) = -20<br> Solve

ale4655 [162]

Answer:

x=0

Step-by-step explanation:

10(x-2)=-20

10x-20=-20

add 20 on both sides.

10x=0

10 times 0 =0

x=0

Art [367]

Answer:

0.4204 probability, option b.

Step-by-step explanation:

Exponential distribution:

The exponential probability distribution, with mean m, is described by the following equation:

$f(x) = \mu e^{-\mu x}$

In which $\mu = \frac{1}{m}$ is the decay parameter.

The probability that x is lower or equal to a is given by:

$P(X \leq x) = \int\limits^a_0 {f(x)} \, dx$

Which has the following solution:

$P(X \leq x) = 1 - e^{-\mu x}$

The probability of finding a value higher than x is:

$P(X > x) = 1 - P(X \leq x) = 1 - (1 - e^{-\mu x}) = e^{-\mu x}$

Children arrive at a house to do Halloween trick-or- treating according to a Poisson process at the unlucky rate of 13/hour

13 arrivals during an hour, which means that the mean time between arrivals, in minutes is of $\mu = \frac{13}{60} = 0.2167$

What is the probability that the time between the 15th and 16th arrivals will be more than 4 minutes ?

This is P(X > 4). So

$P(X > 4) = e^{-0.2167*4} = 0.4204$

So the correct answer is given by option b.

Complete the statement to describe the expression ab + cd + ef + gh.The expression consists ofterms, and each term containsfacto

Marta_Voda [28]

The expression consists of 4 terms, and each term contains 2 factors.

1) In this expression:

ab +cd + ef +gh

We can make the following definitions:

2) Factors are numbers or letters (in algebra) that we can use to multiply themselves and yields another number.

Terms can be defined as letters, numbers within an expression.

3) Hence, In this expression, we have then:

4 terms: ab, cd, ef, and gh

2 factors per term.

The expression consists of 4 terms, and each term contains 2 factors.
