D. box-and-whisker plot

Answer:

This is true

Step-by-step explanation:

When looking at x itself it is just ONE x. 1x=x, the 1x isn't necessary to have so it is shown as x. So looking at x/3 you could say it is also 1x/3 which would still be the same if it were 1/3x. Both would still be considered one-third OF x.

The answer is "[tex]3x=3x[/tex]"

Equating:

[tex]\to \frac{x}{3} = \frac{1}{3}x\\\\x=?[/tex]

Cross multiplying the given expression:

[tex]\to \frac{x}{3} = \frac{1}{3}x\\\\\to 3x=3x[/tex]

Therefore, the given statement is "True"

Option A) when y=6 and w= 2, Option B) when y=4 and w=-1 are the TWO correct choices.

Step-by-step explanation:

The given inequality is w<x<y and x>2.

step 1: let us assume that x=3, since it is given that x>2.

step 2: substitute the value of x=3 and each options in the inequality

step 3: option A) w=2, y=6. Then w<x<y = 2<3<6 (the condition satisfies).

            option B) w= -1, y=4. Then w<x<y = -1<3<4 (the condition satisfies).

            option C) w= 0, y=2. then w<x<y ≠ 0<2<2 (does not satisfies).

            option D) w= -2, y=0. then w<x<y ≠ -2<2<0 (does not satisfies).

            option E) w= -4, y= -1. then w<x<y ≠ -4<2<-1 (does not satisfies).

Answer: 12.5

Step-by-step explanation:

As y=x has a slope of 1, it will intersect the line x = 5 at a value of 5, creating an isocoles right triangle with leg length 5. The area of a triangle = (b*h)/2. (5*5)/2 = 12.5 square units

To find the area of the triangle enclosed by the lines y = x and x = a when a = 5, we need to determine the coordinates of the vertices of the triangle. The vertices are (0, 0), (5, 0), and (5, 5). Using the coordinates, we can find the base and height of the triangle and then apply the formula for the area of a triangle.

To find the area of the triangle enclosed by the lines y = x and x = a, where a = 5, we need to determine the coordinates of the vertices of the triangle. The vertices will be the points where the lines intersect the axes. For y = x, the vertex is (0, 0), and for x = a, the vertex is (5, 0). The third vertex will be the point where these two lines intersect, which can be found by substituting the value of a into the other equation. So, when a = 5, the third vertex is (5, 5).

We can now use the coordinates of the vertices to find the base and height of the triangle. The base is the distance between the points (0, 0) and (5, 0), which is 5 units. The height is the distance between the points (5, 0) and (5, 5), which is also 5 units.

The formula for the area of a triangle is (1/2) × base × height. Substituting the values, we have (1/2)× 5 × 5 = 12.5 square units. Therefore, the area of the triangle when a = 5 is 12.5.

Final answer:

The hockey player must score 20 goals to make the same money as the first contract.

Explanation:

In order to make the same amount of money as the first contract, the hockey player must calculate the number of goals required. Let's assume the player needs to score 'x' goals.

For the first contract, the total salary would be 50000 + 1000x. For the second contract, the total salary would be 40000 + 1500x.

Equating the two salaries, we get:

50000 + 1000x = 40000 + 1500x

Subtracting 1000x from both sides, we get:

50000 = 40000 + 500x

Subtracting 40000 from both sides, we get:

10000 = 500x

Dividing both sides by 500, we get:

x = 20

So, in order to make the same money as the first contract, the player must score 20 goals.

Answer:

Step-by-step explanation:

The set of values are 2, 4, 7, 8, 9.

The mean of these values are [tex]\frac{2 + 4 + 7 + 8 + 9}{5} = \frac{30}{5} = 6[/tex].

The mean of the squares of the differences of these numbers and the mean is [tex]\frac{(6 - 2)^{2} + (6 - 4)^{2} + (6 - 7)^{2} + (6 - 8)^{2} + (6 - 9)^{2}}{5} = \frac{(4)^{2} + (2)^{2} + (-1)^{2} + (-2)^{2} + (-3)^{2}}{5} = \frac{34}{5} = 6.8[/tex].

In order to get the value of the standard deviation, we need to square-root the value of 6.8.

Hence, the standard deviation of the data set is [tex]\sqrt{6.8} = 2.607680962081[/tex] ≅2.6076809621.

Answer:

C

Step-by-step explanation:

The equation of the function g(x) after the transformation is g(x) = kn(x - 3).

A vertical asymptote of a function is the vertical line x = c such that the function tends to approach to infinity as the value of x approaches c.

Given a function f(x) = = ln (x).

The vertical asymptote of the logarithmic function is x = 0.

If the vertical asymptote of the new function is x = 3, this means that the function is shifted to the right by 3 units.

When f(x) is shifted to right by k units, new function is f(x - k).

So the function g(x) is,

g(x) = f(x - 3) = ln (x - 3).

Hence the correct option is C.

2160×1.10

i believe it is this

Final answer:

The original price of the motorbike is calculated by dividing the final price of $2160 by 0.9, which represents the 90% price paid after a 10% discount. The original price of the motorbike was $2400 before the discount was applied.

Explanation:

The question asked us to calculate the original price of a motorbike before a 10% discount was applied and the final price came down to $2160. To do this, we recognize that the final price ($2160) is 90% of the original price because a 10% discount was given. Thus, if we let the original price be 100%, we can find it by dividing the final price by 0.9 (which represents 90%).

Here's the step-by-step calculation:

Express the discount as a decimal: 10% = 0.1.

Determine the percentage of the original price paid: 100% - 10% = 90% = 0.9.

Calculate the original price: Original Price = Final Price / 0.9.

Substitute the known value: Original Price = $2160 / 0.9.

Perform the division to find the original price: Original Price = $2400.

The original price of the motorbike was therefore $2400 before the discount.

Answer:

Reflection in the x-axis followed by a translation 5 units left and 1 unit up

Step-by-step explanation:

The coordinates of X are (-6,2).

When we reflect in the x-axis we get X'=(-6,-2)

When we translate by the rule T(x-5,y+1), we get X"=(-6-5,-2+1)=(-11,-1)

The coordinates of Y are (-4,7).

When we reflect in the x-axis we get Y'=(-4,-7)

When we translate by the rule T(x-5,y+1), we get Y"=(-4-5,-7+1)=(-9,-6)

The coordinates of Z are (-2,2).

When we reflect in the x-axis we get Z'=(-2,-2)

When we translate by the rule T(x-5,y+1), we get Z"=(-2-5,-2+1)=(-7,-1)

Therefore the sequence of transformation is a reflection in the x-axis followed by a translation 5 units left and 1 unit up.

Volume of a cone [tex]=942.86cm^3[/tex]

Step-by-step explanation:

Given that the radius of a cone is 15cm and its height is 4cm

That is r=15cm and h=4cm

To find the volume of a cone :

volume of a cone[tex]=\frac{\pi r^2h}{3}[/tex] cubic units

Now substitute the values in the formula we get

volume of a cone[tex]=\frac{(\frac{22}{7}) (15)^2(4)}{3}[/tex]  

[tex]=\frac{(\frac{22}{7}) (225)(4)}{3}[/tex]

[tex]=\frac{19800}{21}[/tex]

[tex]=942.857[/tex]

Now round to nearest hundredth

[tex]=942.86[/tex]

Therefore Volume of a cone[tex]=942.86cm^3[/tex]

142 sodas and 71 hot dogs are sold

Solution:

Let "a" be the number of sodas sold

Let "b" be the number of hot dogs sold

At a football game, a vender sold a combined total of 213 sodas and hot dogs

Therefore,

number of sodas sold + number of hot dogs sold = 213

a + b = 213 ------------ eqn 1

The number of sodas sold was two times the number of hot dogs sold

Number of sodas sold = two times the number of hot dogs sold

a = 2b ---------- eqn 2

Let us solve eqn 1 and eqn 2

Substitute eqn 2 in eqn 1

2b + b = 213

3b = 213

b = 71

Substitute b = 71 in eqn 2

a = 2(71)

a = 142

Thus 142 sodas and 71 hot dogs are sold

To calculate the location of the diver after 12 1/2 seconds, use the formula: location = initial location - (rate of descent * time). The location of the diver after 12 1/2 seconds is -28.

To calculate the location of the diver after 12 1/2 seconds, we can use the formula: location = initial location - (rate of descent * time). Since the diver is descending at a rate of 2 1/4 per second, we can plug in the values to calculate their location after 12 1/2 seconds.

Initial location: 0 (surface of the water)

Rate of descent: 2 1/4 per second

Time: 12 1/2 seconds

Using the formula, we have: location = 0 - (2 1/4 * 12 1/2)

Calculating the expression, we find that the location of the diver after 12 1/2 seconds is -28.

Answer:

A two-dimensional slice of a three-dimensional solid is called a cross section. Rectangular prisms have the unique property that a perpendicular cross section (a slice of the prism at a 90-degree angle) always creates a rectangle, no matter where on the prism the cross section is taken.

There are three different types of cross sections of a rectangular prism: x-axis, y-axis and z-axis cross sections, corresponding to slices along one of the three dimensions of space. The sum of these three cross sections is equal to half the surface area of the prism.

Different shapes are formed when a rectangular prism is sliced at different angles due to the way the cut intersects the prism's dimensions. For instance, if you cut diagonally or at an angle, the resulting face could be a parallelogram or even a triangle.

When a rectangular prism is sliced at an angle, a variety of shapes can form because of the geometry and dimensions of the prism. Imagine a simple rectangular prism, like a cube. If you slice it horizontally or vertically, you’ll simply create smaller rectangles or squares. However, if you cut diagonally or at an angle, the resulting face could be a parallelogram or even a triangle, depending on how the cut is made. This is a result of changing the orientation of the cut relative to the prism's structure. So, the variety of shapes come as a result of the way the cut intersects the prism's dimensions.
