Answer:

4) n = 12

5) n = 2.5

Step-by-step explanation:

4) 45/4 = 11.25

135/11.25 = 12

5) 2/1 = 2

5/2 = 2.5

4) n=12 this is because 45/4=11.25 and dividing 135 by 11.25 equals to 12

5) n=2.5 this is because 5/2=2.5 and multiplying 1 by 2.5 equals to 2.5

hope this helps :)

The multiplication property of equality could be used to solve which of the following equations?
Evgesh-ka [11]

Multiplication property of equality can be used to solve: \frac{b}{-2} = 18

Step-by-step explanation:

First of all, lets define the multiplication property of equality

The multiplication property of equality states that if one side of an equation is multiplied with any number the other side is also multiplied with the number.

Given equations are:

(x+2)(x-2) = 0\\m+7 = -12\\\frac{b}{-2} = 18\\-3+y = 7

By observing the equations we can see that only third equation has a fraction in it so it has to be multiplied with -2 for solution

\frac{b}{-2} * - 2 = 18*-2\\b = -36

Hence,

Multiplication property of equality can be used to solve: \frac{b}{-2} = 18

Assume that the Poisson distribution applies and that the mean number of hurricanes in a certain area is 5.8 per year. a. Find t
maw [93]

Answer:

a. 0.098

b. 4.41

c. Yes, it does.

Step-by-step explanation:

a.

The Poisson distribution's equation is:

P(x) = (nˣ*e⁻ⁿ)/x!

where P is the probability, n is mean number, and x the number of the event happens, so:

P(3) = \frac{5.8^3*e^{-5.8}}{3!}

P(3) = 0.098

b.

For 45 years, the years that are expected to have 3 hurricanes are

P(3) * 45 = 0.098*45 = 4.41

c.

Yes, it does. The Poisson distribution works well because the observed value of the number of years that 3 hurricanes occur is 45-year period is very close to the calculated value.
