The Values In The Table Represent A Linear Function. How Does The Value Of Y Change In Relation To A

Answers

Answer 1

B) for every change in x by -4, y changes by -6

Determining the relation between x and y:

To determine the relationship between changes in x and y, calculated the slope of the line passing through the given points.

The slope represents the change in y for every change in x. Hence, use the following formula to calculate the formula

             Slope (m) = [ y₂ - y₁]/ [x₂ - x₁]

Here we have

The table

x     9     3     - 3      - 9

y     4     0     -4       - 8

To determine the answer, we need to calculate the slope of the line passing through the points (9, 4), (3, 0), (-3, -4), and (-9, -8).

Using the formula for slope:

slope = [ y₂ - y₁]/ [x₂ - x₁]

For the first two points: (9, 4) and (3, 0)

slope = (0 - 4) / (3 - 9) = (-4) / (-6) = 2/3

For the second two points: (-3, -4) and (-9, -8)

slope = (-8 - (-4)) / (-9 - (-3)) = (-4) / (-6) = 2/3

Since the slope is the same for both sets of points, we can conclude that the linear function represented in the table has a constant slope of 2/3 and the slope is positive.

This means that for every change in x by 3, y changes by 2.

Therefore, the correct response is:

B) for every change in x by -4, y changes by -6

Identify the equation that represents a quadratic relationship
y =4x^2
y =4x^4
y =4x^3
y =4

Answers

The equation that represents a quadratic relationship is y = 4x^2. Option A.

A quadratic relationship is a mathematical relationship where the variable y is a function of the variable x raised to the power of 2. In other words, it is an equation in which the highest power of the variable is 2.

Let's analyze the given equations:

1. y = 4x^2: This equation represents a quadratic relationship because the variable x is raised to the power of 2. The term 4x^2 indicates that the relationship between x and y is quadratic.

2. y = 4x^4: This equation represents a quartic relationship, not a quadratic relationship. The variable x is raised to the power of 4, which indicates a higher degree relationship than quadratic.

3. y = 4x^3: This equation represents a cubic relationship, not a quadratic relationship. The variable x is raised to the power of 3, indicating a higher degree relationship.

4. y = 4: This equation represents a linear relationship, not a quadratic relationship. It is a constant equation where y is always equal to 4, regardless of the value of x. In a quadratic relationship, the variable x should have a power of 2. Option A.

Focus Question #4 + Rita can choose from 2 membership options at a movie rental store. Option A has a yearly fee of $40 and every movie rental costs $3. Option B has a yearly fee of $150 for unlimited movie rentals at no additional cost. How many movies would Rita need to rent in order for Option B to be cheaper than Option A? ​

Answers

Rita would need to rent at least 37 movies in a year for Option B to be cheaper than Option A.

To determine the number of movies Rita would need to rent for Option B to be cheaper than Option A, we can set up an equation and solve for the unknown variable.

Let's assume Rita rents "x" number of movies in a year.

For Option A:

Yearly fee = $40

Cost per movie rental = $3

Total cost for Option A = Yearly fee + (Cost per movie rental * Number of movie rentals)

Total cost for Option A = $40 + ($3 * x) = $40 + $3x

For Option B:

Yearly fee = $150

Cost per movie rental = $0 (unlimited movie rentals)

Total cost for Option B = Yearly fee + (Cost per movie rental * Number of movie rentals)

Total cost for Option B = $150 + ($0 * x) = $150

We want to find the number of movies (x) at which Option B becomes cheaper than Option A. So we can set up the inequality:

$150 < $40 + $3x

Now, we can solve the inequality:

$150 - $40 < $3x

$110 < $3x

Dividing both sides of the inequality by $3:

($110 / $3) < ($3x / $3)

Approximately 36.67 < x

Since the number of movies must be a whole number, we round up to the nearest whole number:

x ≥ 37

Therefore, Rita would need to rent at least 37 movies in a year for Option B to be cheaper than Option A.

Henry is choosing between two exercise routines. In routine #1, he burns 22 calories walking. He then runs at a rate that burns 8.5 calories per minute. In routine #2, he burns 38 calories walking. He then runs at a rate 5.3 calories per minute. For what amounts of time spent running will routine #1 burn at most as many calories as routine #2? Use t for the number of minutes spent running, and solve your inequality for t.

Answers

We want routine #1 to burn at most as many calories as routine #2. So, if we call A the amount of calories burnt during routine #1, and B the amount burnt during routine #2, we should have:

A ≤ B

Now, he burns during routine #1:

A = 22 cal + (8.5 cal/min) * t

And, during routine #2, he burns:

B = 38 cal + (5.3 cal/min) * t

Then, using these expressions for A and B, we have:

22 cal + (8.5 cal/min) * t 38 cal + (5.3 cal/min) * t

Now, in order to solve this inequality for t, we can apply a sequence of algebraic operations on both sides of this inequality, until we isolate the variable t and find its value:

22 cal + (8.5 cal/min) * t 38 cal + (5.3 cal/min) * t

22 cal + (8.5 cal/min) * t - 22 cal 38 cal + (5.3 cal/min) * t - 22 cal

(8.5 cal/min) * t ≤ 16 cal + (5.3 cal/min) * t

(8.5 cal/min) * t - (5.3 cal/min) * t ≤ 16 cal + (5.3 cal/min) * t - (5.3 cal/min) * t

(3.2 cal/min) * t ≤ 16 cal

(3.2 cal/min) * t/(3.2 cal/min) ≤ 16 cal/(3.2 cal/min)

t ≤ (16 cal) * min/(3.2 cal)

t ≤ 5 min

Therefore, routine #1 burns at most as many calories as routine #2 for

t ≤ 5 min

Consequently, if a student answered every question incorrectly the student would earn a score of -20 on the exam. However, if a student answered every question correctly, the student would earn a score of 20 on the exam. After the exam, the teacher distributes the list of test scores and asks the class to calculate the standard deviation. The first student to finish the calculations says that the standard deviation is -1.8.

a. True

Answer:

Step-by-step explanation:

The answer is false because the standard deviation was miscalculated.

We can compute the formula for calculating the standard deviation as:

\(\sigma = \sqrt{\dfrac{\sum (x_i-\overline x)^2}{n}}\)

As a result of the  square in the numerator of the summation, the square \(\sum (x_i-\overline x)^2\)   is usually non-negative.

Even if the data is positive, negative or zero, as a result of the above claim, the standard deviation is always non-negative.

Thus, the fact that the first student who finishes the calculation first and claim that the standard deviation is -1.8 is false.
