Answer:
The correct option is A.
Step-by-step explanation:
The given rule of translation is
[tex](x,y) \rightarrow (x-7,y-7)[/tex] ..... (1)
The rule of translation is defined as
[tex](x,y) \rightarrow (x+a,y+b)[/tex] ......(2)
Where, a is horizontal translation and b is vertical translation.
If a>0, then graph shifts a units right and if a<0, then graph shifts a units left.
If b>0, then graph shifts b units up and if b<0, then graph shifts b units down.
From equation (1) and (2) we get
[tex]a=-7,b=-7[/tex]
Since a=-7<0 and b=-7<0, therefore graph translated 7 units to the left and 7 units down.
Therefore the correct option is A.

The weight of football players is normally distributed with a mean of 200 pounds and a standard deviation of 25 pounds. the probability of a player weighing less than 250 pounds is closest to:
Using the normal distribution, it is found that there is a 0.9772 = 97.72% probability of a player weighing less than 250 pounds.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem:
The mean is of [tex]\mu = 200[/tex].The standard deviation is of [tex]\sigma = 25[/tex].The probability of a player weighing less than 250 pounds is the p-value of Z when X = 250, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{250 - 200}{25}[/tex]
[tex]Z = 2[/tex]
[tex]Z = 2[/tex] has a p-value of 0.9772.
0.9772 = 97.72% probability of a player weighing less than 250 pounds.

What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
It is given that:
The rule (x, y)→(x+2, y−4)
As we know, when we go right side of the x-axis we add to the x-coordinate, and when we go left side of the x-axis we subtract to the x-coordinate.
The rule (x, y)→(x+2, y−4) represents a translation of 2 units right.
When we go upside of the y-axis we add to the y-coordinate, and when we go down the side of the y-axis we subtract to the y-coordinate.
The rule (x, y)→(x+2, y−4) represents a translation 4 units down.
Thus, the rule (x, y)→(x+2, y−4) represents a translation of 2 units right and 4 units down.

if (2x-3) and (x+5) are multiplied to form the trinomial ax^2 +bx+c, what is the value of b
After using the trinomial The required value of b is 7.
What is a trinomial?
An algebraic expression with three terms is called a trinomial. One or more terms in an algebraic expression each have variables and constants. These expressions use separators like +, -,, and that are symbols or operations. This algebraic expression encompasses polynomials, monomials, binomials, and trinomials. An algebraic expression that is created by squaring a binomial expression is known as a perfect square trinomial. It takes the shape of ax2 + bx + c. Real numbers a, b, and c are present here, and a 0. Take the binomial (x + 2), for instance, and multiply it by (x + 2). The outcome is equal to x2 + 4x + 4.

Multiply r^2 + 7r + 10 / 3 by 3r - 30 / r^2 - 5r - 50
A. r + 2
B. 7r^2 - 20r - 300 / -5r - 5
C. (r + 5)( r + 2) / (r + 10)
D. 3r + 6 / 2
By factoring and simplifying the given polynomials, we found that the expressions simplify to r + 2. Therefore, the correct answer is option A. This process involves cancelling out common factors from the numerator and the denominator.
Polynomial Multiplication and Simplification
To solve the problem, we need to multiply the given rational expressions and simplify the result. The expressions are:
(r^2 + 7r + 10) / 3 and (3r - 30) / (r^2 - 5r - 50)
First, let's factor the polynomials where possible:
Factor the numerator of the first expression:[tex]r^2 + 7r + 10 = (r + 2)(r + 5)[/tex]Factor the denominator of the second expression: [tex]r^2 - 5r - 50 = (r - 10)(r + 5)[/tex]Now, the problem can be written as:
([tex](r + 2)(r + 5) / 3 ) * ( 3(r - 10) / (r - 10)(r + 5) )[/tex]
Next, we simplify by canceling out the common factors:
[tex]=( (r + 2)(r + 5) / 3 ) * ( 3(r - 10) / (r - 10)(r + 5) )[/tex]
The (r + 5) terms and the (r - 10) terms can be canceled:
[tex]= (r + 2) / 1[/tex]
So, the simplified answer is r + 2,
The correct option is A. r+2

Answer:
Sampling Distribution
Step-by-step explanation:
A sample is a portion of the population chosen randomly or with certain techniques.
A statistic is a property of sample that describes the sample
Sampling distribution of statistic is a collection of all possible values of statistics for samples taken from the population. To be more precise it is probability distribution of all the outcomes of statistics of samples from the population.
Sample distribution of mean:
It can be defined as the probability distribution of all the feasible or possible means of samples of same size size taken from the population.
Solve 3c − 5f = 55 for f. Show your work.
[tex]\(f = \frac{3c - 55}{5}\)[/tex] is the solution for the given expression.
To solve the equation 3c - 5f = 55 for f, you need to isolate the variable f by performing a series of mathematical operations. Let's go step by step:
Start with the equation:
3c - 5f = 55
Add 5f to both sides to move the term involving f to one side of the equation:
3c = 5f + 55
Subtract 55 from both sides to isolate the term with f:
3c - 55 = 5f
Now, divide both sides by 5 to solve for f:
(3c - 55) / 5 = f
f = (3c - 55) / 5
So, [tex]\(f = \frac{3c - 55}{5}\)[/tex] is the solution for (f).
What is the justification for each step in the solution of the equation 3(2x + 7) - 4 = 53 - 3x?
Step 1: 3(2x + 7) - 4 = 53 - 3x
Step 2: 6x + 21 - 4 = 53 - 3x
Step 3: 6x + 17 = 53 - 3x
Step 4: 9x + 17 = 53
Step 5: 9x = 36
Step 6: x = 4
Final answer:
The equation 3(2x + 7) - 4 = 53 - 3x is solved through algebraic processes: distributing, combining like terms, transposing terms, isolating the variable, and dividing to solve for x, resulting in the solution x=4.
Explanation:
The justification for each step in solving the equation 3(2x + 7) - 4 = 53 - 3x involves algebraic manipulation:
Distribute the 3 into the parenthesis: 3(2x) + 3(7) - 4 = 53 - 3x becomes 6x + 21 - 4 = 53 - 3x.Combine like terms on the left side: 6x + 17 = 53 - 3x.Add 3x to both sides to get all x terms on one side: 9x + 17 = 53.Subtract 17 from both sides to isolate the term with x: 9x = 36.Divide both sides by 9 to solve for x: x = 4.Each step is justified by the rules of algebra which allow us to simplify and rearrange equations to isolate the variable. The final step gives us the solution x = 4.

Determine the x- and y-intercepts of the graph of y=−1/3x+3 .
Then plot the intercepts to graph the equation.
Answer:
you would graph (0,3) and (9,0)
Step-by-step explanation:
Consider the provided equation.
The x intercepts are the points where y value is zero. Similarly the y intercepts are the points where x values is zero.
In order to find the x intercept substitute y = 0 in the provided equation.
0=-1/3x + 3
-3=-1/3(x)
-9=-x
9=x
Thus, the x intercept is (9,0)
In order to find the y intercept substitute x = 0 in the provided equation.
y=-1/3(0) + 3
y=3
Thus, the y intercept is (0,3)
Now use the x and y intercepts to draw the graph of the equation.
The required graph is shown in figure 1.
Therefore, the x- and y- intercepts is (9,0) and (0,3)

Suppose you have 52 feet of fencing to enclose a rectangular dog pen. The function A = 26x = x2 where x = width, gives you the area of the dog pen in square feet. what width gives you the maximum area? what is the maximum area? round to the nearest tenth if necessary.
maximum area is a square
the side of the square would be 52/4 = 13 feet
area = 13*13 = 169 square feet
Answer:
Width = 13 ft
Maximum Area = 169 ft²
Step-by-step explanation:
Given: A rectangular dog pen whose fencing is 52 feet.
Let length be y and width be x
Fencing = 2(l+b)
52 = 2 (x+y)
x + y = 26
y = 26 - x
Area of rectangular pen = Length x width
= y . x
[tex]A=x(26-x)[/tex]
[tex]A=26x-x^2[/tex]
It is parabolic equation. Maximum/Minimum at vertex.
[tex]x=-\dfrac{b}{2a}[/tex]
where, a=-1, b=26
[tex]x=\dfrac{26}{2}=13[/tex]
Now we put x=13 into A
[tex]A=13(26-13)[/tex]
[tex]A=169[/tex]
Hence, The width is 13 feet and Maximum area is 169 ft²
