Answer:

To find the total number of outcomes for this event, find the permutation of ⇒ 9.

The total number of outcomes is 3024

The total number of favorable outcomes is a permutation of ⇒ 4

The probability that the lock code consists of all even digits is ⇒ 24 out of 3,024.

Step-by-step explanation:

Probability of lock code with all even digits =  (4/9) ^ 4 =  256/6561 = 0.039 

So probabiilty of lock without all even digits = 1 - 0.039  =  0..961.

What is the equation graphed in this figure?
laiz [17]
The correct answer is D. If you look at the equation you can see that the line crosses at the points (1,5) and (-2, -4). Use this set of ordered pairs to find the slope. (-4-5)/(-2-1) = (-9/-3) = 3 The use the point-slope formula and fill in the ordered pair (1,5) with the slope. y - 5 = 3( x - 1)

Chase has been playing a game where he can create towns and help his empire expand. Each town he has allows him to create 1.13 t
riadik2000 [5.3K]

Well the way I see it is he started with 4 villager so I would see the equation to be

 1.13x times 17+4 would equal the amount of villagers he could have which would be 23.21 as for the equation it would be 1.13x times 17 plus four equals the number of villagers total

The pipe fitting industry had 546.5 thousand jobs in 2015 and is expected to decline at an average rate of 3 thousand jobs per y
lesya692 [45]

Answer:

The amount of jobs from fitting industry shall decline in 5.5 percent from 2015 to 2025.

Step-by-step explanation:

Due to the assumption of a yearly average rate, a linear function model shall be used. The expected amount of jobs (n) after a certain amount of years (t) is given by the following formula:

n = n_{o} + \frac{\Delta n}{\Delta t}\cdot t

Where:

n_{o} - Initial amount of jobs in pipe fitting industry, measured in thousands.

\frac{\Delta n}{\Delta t} - Average yearly rate, measured in thousands per year. (A decline is indicated by a negative sign)

If n_{o} = 546.5, t = 2025-2015 = 10\,years and \frac{\Delta n}{\Delta t} = -3\,\frac{1}{years}, then:

n = 546.5+\left(-3\,\frac{1}{year}\right)\cdot (10\,years)

n = 516.5

The percent change in jobs from pipe fitting industry is calculated as follows:

\%n = \left(1-\frac{n}{n_{o}}\right)\times 100\,\%

\% n = \left(1-\frac{516.5}{546.5}\right)\times 100\,\%

\%n = 5.5\,\%

The amount of jobs from fitting industry shall decline in 5.5 percent from 2015 to 2025.
