Pam expected the new edition of her favorite video game, Solar Y, to sell for $45. Her prediction was 12.5% higher than the game's actual cost. What was the actual cost of the game?

Answer:

Part A: Yes, there is a correlation between the number of employees in the plant and the number of products produced monthly. This is because as the number of employees increases, the number of products produced also increases in a linear fashion.

Part B: The function that best fits this data is y = 8x + 120, where x is the number of employees and y is the number of products.

Part C: The slope of this plot indicates that for every additional employee, there is an increase of 8 products produced monthly. The y-intercept of this plot is 120, which is the number of products that would be produced if there were no employees.

The function graphed above is:

The height of the top of the tree from the ground is h = a * b / (a / b) = a * b

Let's call the height of the tree "h". Then, using trigonometry, we can write two equations to describe the two angles of elevation:

tan(a) = h / a

tan(ß) = h / b

Dividing these two equations, we get:

tan(a) / tan(ß) = h / a * b

Since tan(a) / tan(ß) = a / b, we can substitute this and simplify:

h = a * b / (a / b) = a * b

the average time of 27 minutes is not an accurate representation of the friends' actual times, so the example describes neither accuracy nor precision.

Precision refers to how close multiple measurements are to each other. In this example, the three friends' times are all close to each other (20 minutes, 21 minutes, and 21 minutes), so the measurements are precise.

Accuracy refers to how close a measurement is to the true or correct value. In this example, the average time of the three friends running a 5K is 27 minutes, but the actual average time should be 20.33 minutes (20 + 21 + 21 / 3). So, the measurement is not accurate.

Answer:

I'm sorry but your question is not clear. Can you please provide more context or clarify what you are asking?

Answer:

y = 36

Step-by-step explanation:

Because the problem says y is proportional to the square root of x, we can assume that it is directly proportional.

The general formula for direct proportionality is

[tex]y=kx[/tex], where k is the constant of proportionality.

Taking into account the square root of x, we can use the following formula to find k by plugging in x and y:

[tex]y=k\sqrt{x}\\ 21=k\sqrt{49}\\ 21=7k\\3=k[/tex]

Since we found k, we can now use this value and the x we're given for the second part of the problem to find y:

[tex]y=3\sqrt{x} \\y=3\sqrt{144}\\ y=3*12\\y=36[/tex]

Answer: A) T = 63 - 3.8A (where T is the temperature in °F, A is the altitude in thousands of feet)

(B) To find the altitude when the temperature is 9.8°F, we can substitute 9.8 for T and solve for A:

9.8 = 63 - 3.8A

3.8A = 63 - 9.8

3.8A = 53.2

A = 14

Step-by-step explanation:

a. (f + g) (0) = 0

b. (f/g) (3) = 2/3

This can be solved by function method.

Function is a mathematical phrase, rule, or law that establishes the connection between an independent variable and a dependent variable (the dependent variable). A function is described as a relationship between a group of inputs and one output each. In simple terms, a function is a connection between inputs, with each input corresponding to exactly one output. Every function has its own domain and codomain, as well as a range. f(x), where x is the input, is a common way to refer to a function.

(a) (f + g) (0) = .........

g(0) = 0, f(0) = 0

(f + g) (0) = f(0) + g(0)

(f + g) (0) = 0 + 0

(f + g) (0) = 0

(b)

(f/g) (3) = ............

f(3) = 2, g(1/3) = 1

(f/g) (3) = f(3) × g(1/3)

(f/g) (3) = 2 × (1/3)

(f/g) (3) = 2/3

The value of m∠C in  the triangle  is 42.77°

The sine rule is a mathematical formula used in trigonometry to find the length of a side or the size of an angle in a triangle when two sides and one of the angles opposite to those sides are known. It states that:

a/sin A = b/sin B = c/sin C

Where a, b, and c are the lengths of the sides of the triangle and A, B, and C are the angles opposite to those sides.

m∠A = 47°, a = 28, c = 26.

a/sin A = c/sin C

28/sin 47° = 26/sin C

sin C = (26 sin 47°)/28

sin C = 0.6791

C = arcsin(0.6791)

C = 42.77°

Thus, m∠C = 42.77°

1. f(h(-3)) = 14

2. g(h(-9)) = 110

3. f(g(x)) = 9 - x² - x

A composite funtion is a function that is applied to the output of another function.

The functions are; F(x) = 9 - x, g(x) = x² + x, h(x) = x - 2

The composite functions, which are functions that have a function as an input, aere evaluated as follows

1. h(-3) = (-3) - 2 = -5

f(h(-3)) = f(-5), therefore;

f(-5) = 9 - (-5) = 9 + 5 = 14

f(-5) = 14

f(h(-3)) = 14

2. h(-9) = -9 - 2 = -11

g(h(-9)) = g(-11)

g(-11) = (-11)² + (-11) = 121 - 11 = 110

g(-11) = 110

Therefore; g(h(-9)) = g(-11) = 110

g(h(-9)) = 110

3. g(x) = x² + x

f(x) = 9 - x

Therefore, f(g(x)) = f(x² + x) = 9 - (x² + x) = 9 - x² - x

For the given relation, the domain is  [0,70] and the range is   [0,500].

What is meant by relation?

In mathematics, a relation describes the connection between two distinct sets of data. If more than two non-empty sets are taken into consideration, the relationship between them will be determined if there is a connection between their items. The relationship between two or more sets of values is called a relation.

Assume that there are two sets of ordered pairs, x and y. If set x and set y are related, then the values of set x are referred to as the domain while the values of set y are referred to as the range.

W can also determine domain and range from graphs.

Also, note that the given graph is continuous so the domain and range values all all values in an interval.

The domain represents all the input values which are on the x-axis.

From the given graph, we can see that the domain values are in the interval  [0,70].

The range represents all output values which are on the y-axis.

From the graph, the range values are in the interval [0,500].

Therefore for the given relation, the domain is  [0,70] and the range is   [0,500].

Answer:

The equation to calculate the balance in the account after "x" months would be: y = 100 + 25x

And after 6 months, Alexa would have $250 in his retirement account, and after 12 months, he would have $400 in his account.

Step-by-step explanation:

Let's call the balance in Alexa's retirement account after "x" months "y".

The equation to calculate the balance in the account after "x" months would be:

y = 100 + 25x

After 6 months, Alexa would have added 6 * $25 = $150 to the original balance of $100, so the balance would be:

y = 100 + 25 * 6 = 100 + 150 = $250

After 12 months, Alexa would have added 12 * $25 = $300 to the original balance of $100, so the balance would be:

y = 100 + 25 * 12 = 100 + 300 = $400

So, after 6 months, Alexa would have $250 in his retirement account, and after 12 months, he would have $400 in his account.

By adding the two given fractions we can see that Josiah ate 17/24 of his orange.

We know that first, Josiah ate 3/8 of his orange.

Then at this point, the remaining amount is 5/8 of the orange.

Then he ates 1/3 of the orange (the total orange, not the remaining amount)

Then the total fraction of the orange that he ate is:

3/8 + 1/3

Finding a common denominator we will get:

9/24 + 8/24 = 17/24

We conclude that Josiah ate 17/24 of his orange.

From the question, we have the following parameters that can be used in our computation:

The area of the shaded portion of the given figure is 84 sq. units.

What is meant by area?

The size of a region on a surface is determined by its area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a structure or planar lamina.

From the figure, we can conclude that,

Area of the shaded portion = Area of the square - Area of the four congruent parallelograms.

Now we have to find the area of square and parallelograms separately.

Area of square

Side length l = 12

Area = l *l = 12 * 12 = 144 sq. units

Area of parallelograms

Base b = 5

Height h = 3

Area of 1 parallelogram = b.h = 5 * 3 = 15 sq. units

Since all the parallelograms are congruent,

Area of all 4 parallelograms = 15 * 4 = 60 sq. units

Hence the area of the shaded portion of the given figure = 144 - 60

                                                                                          = 84 sq. units
