Answer:
The function rule g(x) after the given transformations of the graph of f(x)=4x is g(x) = -1/2x
Step-by-step explanation:
Transformation techniques
Transformation is the process of changing the position of an object on the xy-plane.Given the parent functionf(x) = 4xIf the function is not reflected over x-axis, the resulting function will be f(x) = -4xIf the resulting function is compressed by a factors of 1/8, hence the final function rule will be;g(x) = 1/8(-4x)g(x) = -1/2xHence the function rule g(x) after the given transformations of the graph of f(x)=4x is g(x) = -1/2x

The high school a athletic director is asked if football players are doing as well as academically asthe other students athletes. We know from a previous study that the average GPA for the student athletes is 3.10. after an initiative to help improve the GPA of students athletes, the athletic director randomly samples 20 football players and finds that the average GPA of the sample is 3.18 with a sample standard deviation of 0.54 is there a significant improvement use a 0.05 significance level
Answers
The athletic director can therefore draw the conclusion that the average academic standing of football players is comparable to the average standing of other student athletes.
Explain the term t-distribution?Whenever the population's standard deviation is unknown and the data come from such a normally distributed population, the t-distribution characterizes the standardized distances between the sample means and the population mean.The following formula is used to determine the test statistic:
SRS, s = 0.54, n = 40 > 30,
x = 3.18
H0: μ = 3.10
H1: μ > 3.10
α = 0.05
The t-distribution table and our alpha level of.05 are then used to determine our crucial values.
Our critical values are 2.093 for a two specimens with 19 levels of freedom and α = 0.05 level of significance.
t = x - μ / s/√n
t = 3.18 - 3.10/ 54/√20
t = 0.66
This indicates that the measured sample mean of football players, 3.18, is 0.66 standard errors higher than the 3.10 number that was predicted. We are unable to disprove the null hypothesis because the test statistic's value is below the threshold of 2.093.As a result, It is clear that sampling error is the only possible explanation for the discrepancy between both the sample mean as well as the hypothesized value.

The statement that best describes a sequence of transformations in which the blue figure is the image of the red figure is given as follows:
A. Rotate 90° clockwise about the origin and then dilate with respect to the origin using a scale factor of 1/2.
What are the transformations?The horizontal side lengths on the blue figure are given as follows:
8 - 4 = 6 - 2 = 4.
The vertical side lengths on the transformed red figure is of:
4 - 2 = 3 - 1 = 2.
Hence the scale factor of the dilation is given as follows:
2/4 = 1/2.
Which means that options C and D are not correct.
The rules for each rotation are given as follows:
90º degrees clockwise: (x,y) -> (y,-x).90º degrees counter-clockwise: (x,y) -> (-y,x).On the second quadrant, of the blue figure, we have that:
x is negative.y is positive.On the first quadrant, of the red figure, we have that:
x is positive.y is positive.Hence the rotation was clockwise, and option A is correct.

The concept of algebraic expressions is the use of letters or alphabets to represent numbers without providing their precise values. We learned how to express an unknown value using letters like x, y, and z in the fundamentals of algebra. Here, we refer to these letters as variables. Variables and constants can both be used in an algebraic expression. A coefficient is any value that is added before a variable and then multiplied by it.
It is given that Becky has passed 4 scales, whereas her friend Charlotte has passed 8 of them.
Going forward, Becky has committed to passing 4 scales per week, and Charlotte has committed to passing 2 per week.
Let number of weeks be x
Becky has passed 4x + 4
Charlotte has passed 2x + 8
According to question:
4x + 4 = 2x + 8
4x - 2x = 8 - 4
2x = 4
x = 4/2 = 2
Becky has passed 4x + 4 = 4(2) + 4 = 8 + 4 = 12
Charlotte has passed 2x + 8 = 2(2) + 8 = 4 + 8 = 12

What is a expression? What is a mathematical equation? What is Probability?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem. The formula to calculate the probability of occurrence of an event 'A' can be written as -
P(A) = n(A)/n(S)
where -
n(A) = Number of outcomes favorable to event A.
n(S) = Total number of outcomes
Given are two dices rolled.
The total number of favorable outcomes can be calculated as -
[a] = (1,1) to (1,6) = 6
[b] = (2,1) to (2,6) = 6
[c] = (3,1) to (3,6) = 6
[d] = (4,1) to (4,5) = 5
[e] = (5,1) to (5,4) = 4
[f] = (6,1) to (6,3) = 3
n(A) = [a] + [b] + [c] + [d] + [e] + [f] = 6+6+6+5+4+3 = 30
n(S) = 36
So, the probability of occurrence of an event 'A' -
P(A) = n(A)/n(S)
P(A) = 30/36
P(A) = 5/6

The linear function is C(x) = 500 + 1.25x and the revenue function is R(x) = 3.50x.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
From the data:
The linear function:
C(x) = 500 + 1.25x
For revenue:
R(x) = 3.50x
R(50) = 3.50(50) = $175
Using the C(x) and revenue function we can find the number of slushies and profit.

The vertices of triangle ABC are A(−4, 3), B(4, 3), and C(−4, −6). The triangle is dilated with a scale factor of 3. Estimate the perimeter of the dilated figure to the nearest whole number.
Answers
The perimeter of the image of the triangle is approximately equal to 87 units.
How to determine the perimeter of the image of a triangle
In this problem we find the coordinates of the vertices of a triangle: A(x, y) = (- 4, 3), B(x, y) = (4, 3), C(x, y) = (- 4, - 6), of which we must determine the perimeter of its image, which is the result of a scale factor of 3. The perimeter is the sum of the lengths of the triangle. The length of each side of the image of the triangle can be found by Pythagorean theorem and definition of dilation:
l = √[(Δx)² + (Δy)²]
Where:
l - Side lengthΔx - Change in the x-direction.Δy - Change in the y-direction.And the perimeter of the image of the triangle is described below:
p = k · (AB + BC + AC)
Where k is the scale factor.
First, determine the lengths of sides AB, BC and AC:
Side AB
AB = √[[4 - (- 4)]² + (3 - 3)²]
AB = 8
Side BC
BC = √[(- 4 - 4)² + (- 6 - 3)²]
BC = √[(- 8)² + (- 9)²]
BC = √145
Side AC
AC = √[(- 4 - 4)² + (- 6 - 3)²]
AC = 9
Second, determine the perimeter of the image:
p = 3 · (8 + √145 + 9)
p = 3 · (17 + √145)
p = 51 + 3√145
p ≈ 87.125

What is the probability that one of its 400-page novels will contain exactly one page with errors? At most three pages with errors?
Answers
Part A: Probability that one of 400-page novels will have exactly one error-free page is 24.06%.
Part B.) No more than three pages contain errors: 40.06%.
Explain the term binomial distribution?The possibility that a value would take one among two independent values given a particular combination of factors or assumptions is summarized by the statistical distribution known as the binomial distribution.The given data in the question-
X has a binomial distribution that includes,400 pages make up the novel's page count.Error probability p = 0.005Probability of error-free page q = 01 - 0.005 = 0.995The following is the probability mass function (PMF) for X:
P(X = x) = ⁿCₓ . pˣ . qⁿ⁻ˣ
Part A.) One of 400-page novels will have exactly one error-free page.
P(x = 1) = ⁿCₓ . pˣ . qⁿ⁻ˣ
n = 400, x = 1
P(x = 1) = ¹⁰⁰C₁ . (0.005)¹ . (0.995)¹⁰⁰ ⁻ ¹
P(x = 1) = 0.2706
Thus, probability that one of 400-page novels will have exactly one error-free page is 24.06%.
Part B.) No more than three pages contain errors.
P(x ≤ 3) = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3)
P(x = 0) = ¹⁰⁰C₀ . (0.005)⁰ . (0.995)¹⁰⁰ ⁻ ⁰
P(x = 0) = 0.01346
P(x = 1) = ¹⁰⁰C₁ . (0.005)¹ . (0.995)¹⁰⁰ ⁻ ¹
P(x = 1) = 0.0270
P(x = 2) = ¹⁰⁰C₂ . (0.005)² . (0.995)¹⁰⁰ ⁻ ²
P(x = 2) = 0.00068
P(x = 3) = ¹⁰⁰C₃ . (0.005)³ . (0.995)¹⁰⁰ ⁻ ³
P(x = 3) = 0.0000027
Thus, P(x ≤ 3) = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3)
P(x ≤ 3) = 0.01346 + 0.00068 + 0.00068 + 0.0000027
P(x ≤ 3) = 0.4060021
Consequently, the likelihood of at maximum three pages having typographical errors is 40.06%.
