Answers
1) The data is clustered
2) Increased time does not affect the depth of the water.
A scatterplot is a kind of graph in which each point on the graph represents an observation and values for two variables are shown using Cartesian coordinates. Generally, the dependent variable is represented by the y-axis, and the independent variable by the x-axis. Relationships, trends, patterns, and outliers between the variables can be found using scatterplots.
They can demonstrate, for instance, if a correlation is positive, negative, or absent. One can draw conclusions about the potential relationship between the two variables by looking at the point distribution.
Answer:
1) The depth of the water in the swimming pool decreases over time.
2)The data are clustered.
3)There are no outliers in the data.

2(3x + 10)(x + 1) is your answer.
First, factor out -2 from the trinomial, and then factor the resulting quadratic expression by grouping. The correct factored form is -2(3x + 2)(x - 5).
To factor the trinomial “6x² + 26x + 20 completely, follow these steps:
First, factor out the greatest common factor, which is -2:“6x² + 26x + 20 = –2(3x² – 13x – 10).Next, factor the quadratic expression inside the parentheses:
3x² – 13x – 10.
We need to find two numbers that multiply to (3 × -10 = -30) and add up to -13. Those numbers are -15 and 2.Rewrite the quadratic equation using these numbers:
3x² – 15x + 2x – 10.Now, factor by grouping:
3x(x – 5) + 2(x – 5) = (3x + 2)(x – 5).Combining everything, we get:
–2(3x + 2)(x – 5).
Therefore, the correct factored form is (Option A) “2(3x + 2)(x – 5).

What is the axis of symmetry for f(x)=2x2+8x+8
Answers
= 2(x^2 + 4x) + 8
= 2 [ (x + 2)^2 - 4) + 8
axis of symmetry is x = -2 ( because of the (x + 2)^2 )
Answer: The axis of symmetry for the function f(x) is x = -2.
Step-by-step explanation: We are given to find the axis of symmetry for the following function :
[tex]f(x)=2x^2+8x+8~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
We know that
for a function g(x) with the form [tex]g(x)=a(x-h)^2+k,[/tex] the axis of symmetry is given by the following equation :
[tex]x-h=0~~~~\Rightarrow x=h.[/tex]
Now, from equation (i), we have
[tex]f(x)=2x^2+8x+8\\\\\Rightarrow f(x)=2(x^2+4x+4)\\\\\Rightarrow f(x)=2(x+2)^2+0.[/tex]
Therefore, the required axis of symmetry is given by
[tex]x+2=0\\\\\Rightarrow x=-2.[/tex]
Thus, the axis of symmetry for the function f(x) is x = -2.

D) reflect triangle 2 across the y axis and rotate 90° about the origin at
Answers
C) rotate triangle 2 counter-clockwise 90° about the origin
Answer:
The correct option is C.
Step-by-step explanation:
From the given graph it is noticed that the vertices of triangle 1 are P'(-2,2), Q'(-4,4) and R'(-2,4). The vertices of triangle 2 are P(2,2), Q(4,4) and R(4,2).
If a figure rotated counter-clockwise 90° about the origin, then
[tex](x,y)\rightarrow (-y,x)[/tex]
If we rotate triangle 2 counter-clockwise 90° about the origin, then[
[tex]P(2,2)\rightarrow P'(-2,2)[/tex]
[tex]Q(4,4)\rightarrow Q'(-4,4)[/tex]
[tex]R(4,2)\rightarrow R'(-2,4)[/tex]
If we rotate triangle 2 counterclockwise, then we get the triangle 1.
Therefore the correct option is C.

Question options:
$108.60
$77.01
$66.03
$100.56
Answers
For question 2, We need to calculate the total and then find the tax. So, we do this: 25.67*3=77.01. Then we add the skirt to the total (77.01+23.55=100.56). Finally, we calculate the tax cost (100.56*0.08=8.0448). So our total is (100.56+8.0448=108.6048) So the answer is A.
The total amount of his order is $157.03.
The total amount of the order is the sum of the items bought, the tax paid an the cost of shipping and handling .
Total cost of the order = cost of the items bought + tax paid + shipping and handling
Total cost of the items bought = cost of jacket + slacks + shirt
$70 + $30 + $38 = $138
Tax paid = 6% x $138 = $8.28
Shipping and handling = $10.75
Total cost = $138 + $8.28 + $10.75 = $157.03

A pet store has 12 puppies, including 3 poodles, 5 terriers, and 4 retrievers. if rebecka and aaron, in that order, each select one puppy at random without replacement, find the probability that aaron selects a retriever, given that rebecka selects a poodle.
Answers
The probability that Aaron will select a retriever given that Rebecka has selected a poodle is 4/11.
To calculate the probability that Aaron selects a retriever given that Rebecka selects a poodle, we will use the concept of conditional probability. The total number of puppies is 12, and the number of poodle puppies is 3.
When Rebecka selects a poodle, one puppy is removed from the total, leaving 11 puppies, including the same 4 retrievers (since she did not pick a retriever).
The probability that Aaron picks a retriever given Rebecka has picked a poodle is:
P(Aaron picks a retriever | Rebecka picks a poodle) = P(Rebecka picks a poodle and Aaron picks a retriever) / P(Rebecka picks a poodle)
Since Rebecka has already picked a poodle, we focus only on the event where Aaron picks a retriever. So the probability becomes:
P(Aaron picks a retriever | Rebecka picks a poodle) = Number of retrievers left / Total number of puppies left
= 4 retrievers / 11 total puppies
= 4/11

R=x(A+B)
Answers
R=Ax+Bx
Ax=R - Bx
A =(R - Bx)/x
The answer is A =(R - Bx)/x
To solve the equation R=x(A+B) for A, divide both sides by x to get R/x = A+B. Then, subtract B from both sides to isolate A. The final equation is A = R/x - B.
Explanation:The goal is to solve for A in the equation R=x(A+B). It's a simple problem of algebraic manipulation. Here's how to do it step by step:
First, divide both sides of the equation by x to isolate the term (A+B). This gives R/x = A+B.Next, subtract B from both sides of the newly formed equation to isolate A on one side. This gives us A = R/x - B.And there you have it! The value of A in terms of R, x, and B is A = R/x - B.

Under his "Household expenses" Budget category, Mark has allocated $60 per month for pet food. He can purchase "wet food" for $1.50 per can or "dry food" for $3 per bag.
D.) Name a combination of bags and cabs that will allow him to meet his budget exactly.
Answers
We can find answers by creating this equation.
$1.50c + $3.00b = $60
where c and b represent the number of "wet food" cans and "dry food" bags, respectively. We can easily substitute numbers and solve for the other quantity that will satisfy the condition of total cost adding up to $60.
Final answer:
The question asked for a combination of wet and dry pet food that meets a monthly budget of $60. One such combination would be buying 10 bags of dry food and 20 cans of wet food, as 3(10) + 1.5(20) equals $60, which fits the budget exactly. There are also other combinations that can fulfill the budget constraint.
Explanation:
The student asked for a combination of bags and cans of pet food that would allow Mark to meet his monthly budget of $60 exactly. With wet food costing $1.50 per can and dry food costing $3.00 per bag, we can create a simple algebraic equation to find multiple combinations. Let's let x represent the number of bags and y represent the number of cans. The equation can be written as 3x + 1.5y = 60.
To find a combination that fits exactly into Mark's budget, consider the following example:
If Mark buys 10 bags of dry food, that would cost 10 × $3 = $30. He would then have $30 left of his budget. At $1.50 per can, he could buy 20 cans of wet food (because 20 × $1.50 = $30). Thus, one possible combination would be 10 bags and 20 cans. The equation for this would be 3(10) + 1.5(20) = 30 + 30 = 60, which satisfies Mark's budget constraint.
It's important to note that there are other combinations that would also meet Mark's budget exactly. The student could experiment with different numbers of bags (x) and cans (y) to find additional combinations. The key is that the total cost must not exceed $60.

The product of a number (n) and 12 is 64. Which equation shows this relationship

Answers
The equation that shows the relationship between the number (n) and 12 being multiplied to equal 64 is 12n = 64, the correct option is C.
In this equation, the variable n represents the number we are trying to find. The equation states that when we multiply 12 and n together, the result is 64.
To solve this equation and find the value of n, we divide both sides of the equation by 12:
(12n)/12 = 64/12
n = 64/12
Which can be further simplified to:
n = 16/3
Therefore, the equation that represents the relationship between the number (n) and 12 being multiplied to equal 64 is 12n = 64.
