Which is the correct first step in solving the inequality -4(2x-1)>5-3x algebraically?

1 answer:

3 0

The correct first step is to distribute the -4 into 2x - 1. This will result in -8x + 4 > 5 - 3x. Now, the next step is to solve for the equation. This results in:
-5x + 4 > 5
-5x > 1
x < -0.2
Hope this helps!

Answer:

Part a) $7.536\ m$

Part b) $\$34.14$

Step-by-step explanation:

Part 6)

a) How much edging is needed?

we know that

To find out how much edging is needed determine the circumference of the circular garden

The circumference of the circular garden is equal to

$C=\pi D$

where

D is the diameter

we have

$D=2.4\ m$

assume

$\pi =3.14$

substitute

$C=(3.14)(2.4)$

$C=7.536\ m$

Part b) we know that

To find out the cost to edge the garden, multiply the length of edging plastic needed by the cost of $4.53 per meter

$(7.536\ m)(4.53\ \$/m)=\$34.14$

A travelling salesman sells milkshake mixing machines and on average sells 8.9 machines per month. He needs to sell at least 3 m

Goshia [24]

Answer:

0.67% probability he will have to shut down after this month

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

In which

x is the number of sucesses

e = 2.71828 is the Euler number

$\mu$ is the mean in the given time interval.

On average sells 8.9 machines per month.

So $\mu = 8.9$

Using the Poisson distribution, what is the probability he will have to shut down after this month

If he sells less than 3 machines.

$P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)$

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

$P(X = 0) = \frac{e^{-8.9}*8.9^{0}}{(0)!} = 0.0001$

$P(X = 1) = \frac{e^{-8.9}*8.9^{1}}{(1)!} = 0.0012$

$P(X = 2) = \frac{e^{-8.9}*8.9^{2}}{(2)!} = 0.0054$

$P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0001 + 0.0012 + 0.0054 = 0.0067$

0.67% probability he will have to shut down after this month
