Answer: If you need to see a systematic solution, let the 2 numbers be n and n + 2.
n(n + 2) = 63
n2 + 2n - 63 = 0
(n - 7)(n + 9) = 0
n = 7 or -9
If n = 7, then n + 2 = 9
If n = -9, then n + 2 = -7
This is based on knowledge of composite numbers: 7 times 9 = 63.
The only other pair of numbers satisfying this is -7 and -9

Step-by-step explanation:
Suppose a tree limb falls on your house during a storm and causes $9,500 worth of damage to your pool cage. The premium for your homeowners insurance is $150/month, and your deductible is $4,000 with an out-of-pocket maximum of $10,000. If this event is a covered event, how much will you need to pay a contractor to repair the damage to the pool cage?
A: $4000
B: $9500
C$10,000
Answer:B
Step-by-step explanation:
The amount you need to pay a contractor to repair the damage to the pool cage should be considered as the option b $9,500
Calculation of the amount:Since the amount of $9,500 should be considered as the worth of damage to your pool cage.
Also there are other charges like premium, deductible amount, pocket maximum amount, etc.
So based on the payment only $9,500 should be conisdered.

Find the slope and y-intercept of the
equation provided.
Answer: C
Step-by-step explanation:
Hello! :)
[tex]\large\boxed{\text{m = -8, b = 22}}[/tex]
Find the slope and y-intercept by rearranging the equation into the following format:
y = mx + b
We are given the equation:
16x + 2y = 44
Rearrange by subtracting 16x from both sides:
2y = -16x + 44
Divide all terms by 2:
y = -8x + 22
In this equation, the m-value is -8 and the b value is 22.
Therefore, m = -8, and b = 22.

In a bowl that has 12 jolly ranchers candies, there are 3 Yellow 5 Red and 4 Green. you pick two of these Jolly Ranchers from the bowl WITHOUT REPLACEMENT.
1 find the probability that both candies are red?
Answer:
0.15 or 20/132 or 5/33 or 15%
Step-by-step explanation:
5/12 is the probability for the first red candy.
The question says "without replacement" meaning that if one candy is picked it will NOT be picked again and it will not go back to the original bowl. The second red candy is 4/11 (one red candy was already taken out from the first event). Multiply 5/12 and 4/11 to get 20/132. That is simplified to be 5/33 but if you divide it will 0.15 and as a percent it would be 15%.

What is the meaning of 92 in this model?
What does 22 mean in this model?
Answer:
1. 9/2 is the slope.
2. 22 is the intercept on the y-axis
Step-by-step explanation:
From the question given above, the following equation was obtained:
y = 9/2x + 22
1. Determination of the meaning of 9/2
y = 9/2x + 22
Comparing the above equation with:
y = mx + c
m => is the slope
y = 9/2x + 22
y = mx + c
mx + c = 9/2x + 22
Slope (m) = 9/2
Therefore, 9/2 is the slope.
2. Determination of the meaning of 22
y = 9/2x + 22
Comparing the above equation with:
y = mx + c
c => is the intercept on y-axis
y = 9/2x + 22
y = mx + c
mx + c = 9/2x + 22
Intercept (c) = 22
Therefore, 22 is the intercept on the y-axis

D. 7 + or - 2.306 (2.29/underoot 8).
E. 7 + or - 2.306 (2.29/underoot 9).
Answer:
Population mean = 7 ± 2.306 × [tex]\frac{2.29}{\sqrt{9} }[/tex]
Step-by-step explanation:
Given - A university researcher wants to estimate the mean number
of novels that seniors read during their time in college. An exit
survey was conducted with a random sample of 9 seniors. The
sample mean was 7 novels with standard deviation 2.29 novels.
To find - Assuming that all conditions for conducting inference have
been met, which of the following is a 94.645% confidence
interval for the population mean number of novels read by
all seniors?
Proof -
Given that,
Mean ,x⁻ = 7
Standard deviation, s = 2.29
Size, n = 9
Now,
Degrees of freedom = df
= n - 1
= 9 - 1
= 8
⇒Degrees of freedom = 8
Now,
At 94.645% confidence level
α = 1 - 94.645%
=1 - 0.94645
=0.05355 ≈ 0.05
⇒α = 0.5
Now,
[tex]\frac{\alpha}{2} = \frac{0.05}{2}[/tex]
= 0.025
Then,
[tex]t_{\frac{\alpha}{2}, df }[/tex] = 2.306
∴ we get
Population mean = x⁻ ± [tex]t_{\frac{\alpha}{2}, df }[/tex] ×[tex]\frac{s}{\sqrt{n} }[/tex]
= 7 ± 2.306 × [tex]\frac{2.29}{\sqrt{9} }[/tex]
⇒Population mean = 7 ± 2.306 × [tex]\frac{2.29}{\sqrt{9} }[/tex]

The area of the base is given by The volume of a hexagonal prism is given by 35x ^ 5 + 20x ^ 4 - 57x ^ 3 + x ^ 2 + 18x - 30 5x ^ 2 - 6 Find an expression for the height of the hexagonal prism.
Answer:
Step-by-step explanation:
The height of given hexagonal prism is 7x³+4x²-3x+5.
Given that, the volume of a hexagonal prism is [tex]35x ^ 5 + 20x ^ 4 - 57x ^ 3 + x ^ 2 + 18x - 30[/tex] and the area of the base is 5x² - 6.
What is a hexagonal prism volume?A hexagonal prism is a three-dimensional solid shape with 8 faces that including hexagon bases.
Volume of a hexagonal prism = Area of a base × Height.
Here, [tex]35x ^ 5 + 20x ^ 4 - 57x ^ 3 + x ^ 2 + 18x - 30[/tex] = 5x² - 6 × Height
Height = [tex]35x ^ 5 + 20x ^ 4 - 57x ^ 3 + x ^ 2 + 18x - 30[/tex] ÷ 5x² - 6
5x² - 6| [tex]35x ^ 5 + 20x ^ 4 - 57x ^ 3 + x ^ 2 + 18x - 30[/tex] | 7x³+4x²-3x+5

Find three positive numbers whose sum is 140 and whose product is a maximum. (Enter your answers as a comma-separated list.)
Answer:
[tex]\frac{140}{3}, \frac{140}{3}, \frac{140}{3}[/tex]
Step-by-step explanation:
Let the numbers be [tex]x, y\ and\ z.[/tex]
Such that:
[tex]x + y + z = 140[/tex]
Make z the subject
[tex]z = 140 -x - y[/tex]
For their product to be maximum, we have:
[tex]f(x,y,z) = xyz[/tex]
Substitute [tex]z = 140 -x - y[/tex] in [tex]f(x,y,z) = xyz[/tex]
[tex]f(x,y) = xy(140 - x - y)[/tex]
Open bracket
[tex]f(x,y) = 140xy - x^2y - xy^2[/tex]
Differentiate w.r.t x and y
[tex]f_x=140y - 2xy - y^2[/tex]
[tex]f_y=140x - x^2 - 2xy[/tex]
Since the products are maximum, then [tex]f_x = f_y = 0[/tex]
For [tex]f_x=140y - 2xy - y^2[/tex]
[tex]140y - 2xy - y^2 = 0[/tex]
Factorize:
[tex]y(140 - 2x - y) = 0[/tex]
Split
[tex]y = 0\ or\ 140 - 2x - y = 0[/tex]
Make y the subject
[tex]y = 0\ or\ y = 140 - 2x[/tex]
For [tex]f_y=140x - x^2 - 2xy[/tex]
[tex]140x - x^2 - 2xy = 0[/tex]
---------------------------------------------------
Substitute y = 0
[tex]140x - x^2 -2x*0 = 0[/tex]
[tex]140x - x^2 = 0[/tex]
Factorize
[tex]x(140 - x)= 0[/tex]
[tex]x = 0\ or\ 140-x = 0[/tex]
[tex]x = 0\ or\ x = 140[/tex]
---------------------------------------------------
Substitute [tex]y = 140 - 2x[/tex]
[tex]140x - x^2 - 2xy = 0[/tex]
[tex]140x - x^2 - 2x(140 - 2x) = 0[/tex]
[tex]140x - x^2 - 280x + 4x^2 = 0[/tex]
Re-arrange
[tex]4x^2 -x^2 +140x - 280x = 0[/tex]
[tex]3x^2 -140x = 0[/tex]
Factor x out
[tex]x(3x - 140) = 0[/tex]
Divide through by x
[tex]3x - 140 = 0[/tex]
[tex]3x = 140[/tex]
[tex]x = \frac{140}{3}[/tex]
Recall that: [tex]y = 140 - 2x[/tex]
[tex]y = 140 - 2 * \frac{140}{3}[/tex]
[tex]y = 140 - \frac{280}{3}[/tex]
Take LCM
[tex]y = \frac{140*3-280}{3}[/tex]
[tex]y = \frac{140}{3}[/tex]
Recall that:
[tex]z = 140 -x - y[/tex]
[tex]z = 140 - \frac{140}{3} - \frac{140}{3}[/tex]
Take LCM
[tex]z = \frac{3 * 140- 140 - 140}{3}[/tex]
[tex]z = \frac{140}{3}[/tex]
Hence, the numbers are:
[tex]\frac{140}{3}, \frac{140}{3}, \frac{140}{3}[/tex]
