Final answer:

To find the number of new games rented, set up an equation using the given information. Assume all 6 games rented were new games, and solve for the number of new games.

Explanation:

To find the number of new games rented, we can set up an equation using the information given.

Let x represent the number of new games rented and y represent the number of older games rented.

We know that the total cost of renting 6 games is $22. Therefore, we can write the equation:

4x + 2y = 22

To find the number of new games rented, we want to solve for x. We can do this by substituting a value for y and solving for x.

Let's assume all 6 games rented were new games, so y = 0.

Substituting this value into the equation gives:

4x + 2(0) = 22

Simplifying, we get:

4x = 22

Dividing both sides by 4, we find that x = 5.5.

Since we can't rent a fractional number of games, the student rented 5 new games.

The IQR is a measure of data distribution and used in outlier detection. The IQR is calculated by subtracting Q1 from Q3. After calculating the IQR, the lower and upper cut-offs can be calculated and data points below or above these cut-offs are considered as outliers.

The interquartile range (IQR) is a measure of statistical dispersion, and it can be useful in identifying 'outliers' in data. The IQR is calculated by subtracting the first quartile (Q1) from the third quartile (Q3) in a data set.

For the provided data set, to find the IQR, it should be sorted in ascending order and then Q1 and Q3 should be calculated. In your case, the sorted data set is: 12.8, 13.0, 13.5, 15.0, 15.0, 15.1, 15.2, 15.5, 15.6, 16.4, 16.6, 17.7, 18.3, 19.1, 19.3, 19.6, 20.5, 21.0, 26.2, 27.8, 33.5.

After finding Q1 and Q3, subtract Q1 from Q3 to get IQR (a.). Then, find the lower and upper cut-offs by subtracting 1.5 times of IQR from Q1 (b.) and adding 1.5 times of IQR to Q3 (c.), respectively. Any data points below the lower cut-off or above the upper cut-off are considered as outliers (d.).

Answer:

The total area of Ohio is about 30 times the total area of Rhode Island

Step-by-step explanation:

Let

x -----> the total area of Ohio in square miles

y -----> the total area of Rhode Island in square miles

we know that

[tex]x=4.5*10^{4}\ mi^{2}[/tex]  

[tex]y=1.5*10^{3}\ mi^{2}[/tex] (searched in Google)

To find out approximately how many times the total area of Ohio is compared to the area of Rhode Island, divide the area of Ohio by the area of Rhode Island

[tex]\frac{x}{y}[/tex]

substitute the values

[tex]\frac{4.5*10^{4}}{1.5*10^{3}}=(\frac{4.5}{1.5})( 10^{4-3}) =3*10^{1}=30[/tex]

therefore

The total area of Ohio is about 30 times the total area of Rhode Island

Ohio is approximately 37.5 times larger than Rhode Island.

To find out how many times larger Ohio is compared to Rhode Island, we need to know the area of both states and then divide the area of Ohio by the area of Rhode Island.

The total area of Ohio is given as[tex]\( 4.5 \times 10^4 \)[/tex]square miles.

The area of Rhode Island is approximately[tex]\( 1.2 \times 10^3 \)[/tex] square miles.

Now, we divide the area of Ohio by the area of Rhode Island to find the factor by which Ohio is larger:

[tex]\[ \frac{\text{Area of Ohio}}{\text{Area of Rhode Island}} = \frac{4.5 \times 10^4}{1.2 \times 10^3} \][/tex]

[tex]\[ = \frac{4.5}{1.2} \times \frac{10^4}{10^3} \][/tex]

[tex]\[ = 3.75 \times 10 \][/tex]

[tex]\[ = 37.5 \][/tex]

Answer: 257

Step-by-step explanation:

|-143 + 400| = 257

The hiker starts 143 feet below sea level (-143). After climbing 400 feet, the hiker is now 257 feet above sea level.

The hiker's initial elevation is 143 feet below sea level, which we represent as -143. The hiker then climbs 400 feet, so we add this to the initial elevation. Therefore, the calculation is: -143 + 400 = 257.

This means that the hiker's new elevation, relative to sea level, is 257 feet above sea level.

Answer: Hello there!

initially Maria has 6 red marbles, 6 blue marbles, and 4 green marbles.

You know that in the first pick, Maria gets a green marble ( this means that now there are 3 green marbles left)

Now we want to know the probability that she gets a red marble on the second pick.

Now there are 6 + 6 + 3 = 15 marbles in the bag, and 6 of them are red ones. Then the probability of getting one red is the number of red ones divided by the total amount ( which is the ratio of red marbles to total marbles)

this is 6/15.

now you can see that there is no 6/15 in the options, so we need to see which one is equivalent.

if we took the option C, 2/5, and multiply both denominator and numerator by 3, we get (3*2)/(3*5) = 6/15, then 2/5 and 6/15 are equivalents.

Then the correct answer is C.

The probability that she gets a red marble on her second pick is 2/5.

Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

The probability that she gets a red marble on her second pick = [number of red marbles / (total number of marbles - 1)]

6 / 15 = 2/5

The function g(x) = f(-x) represents a reflection of the graph of f(x) across the y-axis. This transformation swaps the values of the function for positive and negative x values, creating a mirror image.  So since the max of f was when x = 2, the max of g will be when x = -2.

Understanding the Transformation of Function g(x) = f(-x)

function g(x) = f(-x).

This indicates a transformation where the function f(x) is reflected across the y-axis.

To put it simply, the graph of y = f(-x) is the mirror image of the graph of y = f(x) across the y-axis.

f g(x) = f(-x), the graph of g looks like a mirror image of f, where the y-axis is the mirror.  

For example, g(1) will be what f's value at -1 was (-1).  g(2) = f(-2) = -3.  g(3) = f(-3) = -1.  etc.  

So since the max of f was when x = 2, the max of g will be when x = -2.

Here’s an example to illustrate:

Suppose f(x) = x².

The graph of y = f(x) is a parabola facing upwards.

For y = f(-x), or y = (-x)²,

the graph will still be a parabola facing upwards.

Since g(x) = f(-x), the absolute values are not changed but the sign change in x reflects each point across the y-axis.

This reflection happens because negating the independent variable x means we swap the values of the function at positive and negative x values.

Question:

If the function g is defined so that g(x)=f(-x), then for what value of x does g attain its maximum value?

Answer:

a) Value T's and More

b) y = 8x

c) 8; cost per t-shirt

d) $25

e) Value T's and More for orders of fewer than 25 t-shirts.
    Print-o-Rama for larger orders of more than 25 t-shirts.

Step-by-step explanation:

We are given that Allison’s middle school team has designed t-shirts featuring their team name and color. Allison and her friend Nicole have volunteered to call local stores to get an estimate of the total cost of purchasing the t-shirts.

[tex]\dotfill[/tex]

A proportional relationship is a linear relationship between two variables where the ratio of one variable to the other is constant, and the graph of this relationship passes through the origin (0, 0).

Value T's and More represents a proportional relationship because the cost per t-shirt is constant at $8, and the graph modelling the data for this company passes through the origin (0, 0), meaning that when no t-shirts are purchased, the cost is $0.

Print-o-Rama does not represent a proportional relationship because although they charge a fixed amount per t-shirt, there is an additional set-up fee. This makes the cost function in the form y = mx + b (where b is the set-up fee), resulting in a graph that does not pass through the origin (0, 0).

[tex]\dotfill[/tex]

A proportional relationship can be expressed as y = kx, where k is the constant of proportionality.

Since the cost per t-shirt at Value T's and More is constant at $8, the constant of proportionally is k = 8, so the equation relating cost (y) and shirts (x) for Value T's and More is y = 8x.

[tex]\dotfill[/tex]

As discussed in part b, the constant of proportionality for ValueT's and More is 8. This represents the cost per t-shirt (in dollars).

[tex]\dotfill[/tex]

To find the set-up fee, let's use the given points (10, 95) and (50, 375) for Print-o-Rama and assume the cost model is y = mx + b, where m is the cost per shirt, and b is the set-up fee.

Substitute both points into y = mx + b to set up two equations:

[tex]95=10m + b\\\\375=50m+b[/tex]

Subtract the first equation from the second equation to eliminate b, then solve for m:

[tex]375-95=(50m+b)-(10m+b) \\\\280=40m\\\\m=7[/tex]

This means that the cost per t-shirt is $7.

Substitute m = 7 back into one of the equations and solve for b. Let's use 95 = 10m + b:

[tex]95 = 10(7) + b \\\\95=70+b\\\\b=95-70\\\\b=25[/tex]

Therefore, the set-up fee for Print-o-Rama is $25.

[tex]\dotfill[/tex]

To determine the most cost-effective supplier, we need to equate the cost equations of Value T's and More and Print-o-Rama to identify the exact number of t-shirts at which the costs for both companies are equal:

[tex]8x=7x+25\\\\8x-7x=25\\\\x=25[/tex]

Solving 8x = 7x + 25 for x gives us x = 25, meaning that for an order of 25 t-shirts, the total cost from both suppliers is the same. For orders of fewer than 25 t-shirts, Value T's and More is cheaper, but for orders of more than 25 t-shirts, Print-o-Rama is more cost-effective due to its lower per-shirt cost despite the set-up fee.

Therefore, after analysing the pricing models of both Value T’s and More and Print-o-Rama, it is recommended to use:

a. The graph shows a proportional relationship

b. The proportional equation is  y = 8k

c. The constant of proportionality is 8

d. Print-o-Rama's set up fee is 25

a. A linear graph that intercepts the origin has a proportional relationship.

b. The equation is written in the form y = kx, using point (10, 80)

80 = 10k

k = 8

The equation is written as y = 8k

c. The constant of proportionality is k which is equal to 8

d. The set up fee is the y-intercept (b). The equation is written in the form y = mx + b

m = (375 - 95) / (50 - 10)

m = 280 / 40

m = 7

Using point slope formula

y - 95 = 7 (x - 10)

y = 7x - 70 + 95

y = 7x + 25

The y-intercept, b is 25

Final answer:

To find the side length of the original square, we formed a quadratic equation based on the given information and solved it to get a side length of 5 meters.

Explanation:

The question asks us to find the length of a side of the original square when the sides are increased by 3 meters and the new area becomes 64 square meters. First, let's denote the side length of the original square as x. If each side of the square is increased by 3 meters, then the new side length is x + 3 meters. The area of the new square is given to be 64 m², which can be represented as the square of the new side length, so the equation becomes:

(x + 3)²= 64

This simplifies to:

x² + 6x + 9 = 64

Subtracting 64 from both sides:

x² + 6x - 55 = 0

This is a quadratic equation that we can solve by factoring or using the quadratic formula. In this case, the equation factors to:

(x + 11)(x - 5) = 0

This gives us two possible solutions for x: -11 or 5. Since a side length cannot be negative, we disregard the -11 and conclude that the side length of the original square is 5 meters.

The measure of an angle being equal to itself is an example of the Reflexive Property, which states that any quantity is equal to itself.

The statement "The measure of an angle is equal to itself" is true because of the Reflexive Property. This property states that any quantity is equal to itself, which is a fundamental idea in mathematics and logic. In the context of geometry and angles, it means that an angle is always equal to its measure. So, if θ represents the measure of an angle, then we could say θ = θ, which demonstrates the Reflexive Property.

The other properties listed—the Property of Equality, Symmetric, and Transitive—are also important in the realms of algebra and geometry but do not directly apply to the fact that an entity is equal to itself. Instead, these properties involve the relationship between different entities or the equality between them derived from other equalities.

Answer:

5/3 hours

Step-by-step explanation:

2/3 hour = 40 minutes

You can solve it by proportion:

40 minutes = 2/5 room

x minutes = 1 room

[tex]x=\frac{40}{\frac{2}{5} }[/tex]

100 minutes = 5/3 hours

Answer: 1 hour 40 minute

Step-by-step explanation:

If it take 2/3 of an hour to paint 2/5 of a room

1Hour = 60min

2/3 of 60min

2/3 × 60min

=120min / 3

= 40min

That is it take 40min to paint 2/5 of a room

So using proportion

2/5 room = 40min

1room = X min

We cross multiply

2/5 × X = 40min

2X / 5 = 40min

We cross multiply again

2X = 200min

Divide bothside by 2

x = 100 min

But 1hour =60min

Therefore 100min = 1 hour 40min.

Answer:

x = [tex]\frac{1}{12}[/tex] y²

Step-by-step explanation:

Any point (x, y ) on the parabola is equidistant from the focus and the directrix

Using the distance formula, then

[tex]\sqrt{(x-3)^2+(y-0)^2}[/tex] = | x + 3 |

Squaring both sides

(x - 3)² + y² = (x + 3)² ← expanding both sides

x² - 6x + 9 + y² = x² + 6x + 9 ← subtract x² + 6x + 9 from both sides

- 12x + y² = 0 ( subtract y² from both sides )

- 12x = - y² ( divide both sides by - 12 )

x = [tex]\frac{1}{12}[/tex] y²

Answer:

y²-12x = 0

Step-by-step explanation:

The formula for calculating the equation of a parabola is y² = 4ax

and x = a

To find the equation of the parabola with focus (3, 0) and directrix x = –3,

The point given (x,y) = (3,0) and x = -3

From the data given, it can be seen that a = -3 by simply comparing x = a with x = -3

Similarly, x = 3 from the given point.

Substituting the value of x = -3 in the formula for equation of a parabola gives;

y² = 4(-3)x

y²= -12x

y²-12x = 0
