Answer:

a=-18

Step-by-step explanation:

Let's break this down step by step.

-8-3a=46

Since 3a has a variable, a, we want to get it by itself. So the first step is to do the inverse operation and add 8 on both sides. That leaves this equation:

-3a=54

The 3a is -3a because of the subtraction sign in front. Now we divide on both sides because we want the variable, a, to be by itself. That leaves this simplified expression.

a=-18.

Now, let's work it out in context of the problem.

-8-3x-18=46

3x-18 is -54, and -8-(-54), it would become 46.

Assume that the number of customers who arrive at a water ice stand follows the Poisson distribution with an average rate of 6.4

Nady [450]

Answer:

18.88% probability that three or four customers will arrive during the next 30 minutes

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.

Average rate of 6.4 per 30 minutes.

This means that $\mu = 6.4$

What is the probability that three or four customers will arrive during the next 30 minutes?

$P = P(X = 3) + P(X = 4)$

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

$P(X = 3) = \frac{e^{-6.4}*(6.4)^{3}}{(3)!} = 0.0726$

$P(X = 4) = \frac{e^{-6.4}*(6.4)^{4}}{(4)!} = 0.1162$

$P = P(X = 3) + P(X = 4) = 0.0726 + 0.1162 = 0.1888$

18.88% probability that three or four customers will arrive during the next 30 minutes

n old brainteaser by the Central Asian scholar Biruni (973−1048): If 10 dirhams (a unit of currency) earn 5 dirhams of profit in

mariarad [96]

This is a tricky question because you might use the ratio and proportion method. However, there are 3 terms involved. To cut it down to 2, let's lump the profit rate. The solution is as follows:

10:5/2::8:x/3

Solving for x,
20/5 = 24/x
x = 24(5)/20 = 6

Hence, it will earn 6 dirhams of profit.

How do you write a slope parallel to a line?

antiseptic1488 [7]

Answer:

slope is m. Parallel means it has the same slope as the line it's parallel to. Let's say the slope of line 1 is 3, and your y intercept is 12. The equation would then be y = 3x + b and b would be 12 bc x would be 0 at y intercept making the equation become y = (0)x+b and for y to be 12, b has to be 12 in this case. So y = 3x + 12
