Let x be the number of minutes water has been added.

(a)

For each pool, write an expression for the amount of water in the pool after x minutes.

Amount of water in the first pool (in liters) = ____

Amount of water in the second pool (in liters) = ____

(b)

Write an equation to show when the two pools would have the same amount of water.

______________

Two pools are being filled with water. To start, the first pool had 728 liters of water and the second pool was empty. Water is being added to the first pool at a rate of 23 liters per minute. Water is being added to the second pool at a rate of 37 liters per minute.

Let x be the number of minutes water has been added.

(a)

For each pool, write an expression for the amount of water in the pool after x minutes.

Amount of water in the first pool (in liters) = **23x** **+ 728**

Amount of water in the second pool (in liters) = **37x**

(b)

Write an equation to show when the two pools would have the same amount of water.

this is when:

23x + 728 = 37x

subtract 23x from both sides:

23x + 728 - 23x = 37x - 23x

728 = 14x

divide both sides by 14:

728/14 = 14x/14

x = 52

**So, pools are equal after 52 minutes.**

**Answer:**

Option 2

**Step-by-step explanation:**

**[tex]6x-2 \geq 10 \\ \\ 6x \geq 12 \\ \\ x \geq 2[/tex]**

So, we want a graph with a closed circle at 2 with the arrow pointing to the right.

**Answer:**

2nd choice

**Step-by-step explanation:**

6x - 2 ≥ 10

add 2 to both sides

6x - 2 + 2 ≥ 10 + 2

6x ≥ 12

6x/6 ≥ 12/6

x ≥ 2

**x is greater than or equal to 2**

equal to 2 is shown by a shaded in circle (cannot be option 3 or 4)

a + b - 8 = p solve for a

**Answer:**

a = −b + p + 8

**Step-by-step explanation:**

a + b - 8 = p solve for a

a + b - 8 = p

subtract b from both sides:

a + b - 8 - b = p - b

a - 8 = p - b

add 8 to both sides:

a - 8 + 8 = p - b + 8

a = p - b + 8

rearrange for alphabetical order:

**a = −b + p + 8**

**Answer:**

a = p + 8 - b

**Step-by-step explanation:**

Step 1: Add 8 both sides

[tex]\displaystyle{a+b-8+8=p+8}\\\\\displaystyle{a+b=p+8}[/tex]

Step 2: Subtract b both sides

[tex]\displaystyle{a+b-b=p+8-b}\\\\\displaystyle{a=p+8-b}[/tex]

*Note: You can also subtract b both sides first then add 8 both sides.*

Therefore, the new equation when a-term is the subject is [tex]a=8+p-b[/tex].

customers arrive at a checkout counter in a department store according to a poisson distribution at an average of seven per hour. what are the probabilities that

From the information given in the Poisson Distribution, the **probability **that that no more than three customers arrive that is P (X≤3) = 0.0817.

What is a **Poisson Distribution**?

The Poisson distribution is a discrete **probability **distribution in probability theory and statistics that articulates the likelihood of a specific number of events happening in a fixed interval of time or space if these events occur with a particular frequency mean rate and regardless of the time since the last event.

What Are the **Poisson Distribution's **Assumptions?

To be correct, all events must be independent of one another, the pace of occurrences must be steady across time, and events cannot occur concurrently. Furthermore, the mean and the variance will be equal.

What is the justification for the above result?

According to a Poisson distribution, seven people come at a checkout counter in a department store every hour on average. i.e λ=7

**Probability **(P) that no more than three customers arrive is notated as P(X≤3)
