Anya plays one round of her favorite online game every day. One week, she played 7 rounds and scored between 120 and 300 points each round. She calculated the mean and median of those scores.
Then, Anya found out that the day she scored 300 points was a special "double points" day, so she actually earned 600 points, not 300.
How will this amount increasing affect the mean and median?

Answers

Answer:

D: The mean will increase, and the median will stay the same.

Step-by-step explanation:

Strategy

The mean and median are two ways to describe the center of a data set.

When a data set is almost symmetrical, the mean and median are close together.

When a data set is not symmetrical, the mean is usually closer to the outliers or tail than the median.

Let's reason conceptually about the measures of the center since we do not know the exact values.

Reasoning about the median

There are 7 scores. When the scores are in order from least to greatest, the median is the 4th score.

The day when Anya scored 300 points was the largest score both before and after that score was increased. So that is the 7th score when we order them from least to greatest.

Changing the 7th score does not change the 4th score, so the median stays the same.

Reasoning about the mean

Let's remember how to calculate the mean:

mean = total points/number of rounds

The largest score increasing from 300 to 600 points increases the total number of points. However, it does not change the number of rounds. So the mean increases.

Conclusion

D: The mean will increase, and the median will stay the same.

Pentagon A’B’C’D’E’ is the image of pentagon ABCDE under a dilation with a scale factor of 3/4.

What is the length of segment AE?

Answers

The length of segment A'E'  under a dilation with a scale factor of 3/4 is; 3/2 units.

How to Interpret Scale of Dilation?

From the included graph the coordinates of the points A and E, in the pentagon ABCDE with reference to point A are;

A: (0, 0)

E: (0, 2)

The length of the segment AE = √((2 - 0)² + (0 - 0)²) = √(2²) = 2

When a pentagon ABCDE is dilated to pentagon A'B'C'D'E' with a scale factor of 3/4, we have;

Length of segment A'E' = 3/4 × Length of segment AE

Therefore;

Length of segment A'E' = 3/4 × 2 = 3/2  units.

In the diagram below of triangle DEF, G is a midpoint of D E and H is a midpointof EF. If MZGHE = x + 52, and mZDFH = 96 – 102, what is the measureof ZDFH?

Answers

According to the given figure, angles GHE and DFH are corresponding angles, which are equal because GH and DF are parallels. So, we can express the following

[tex]m\angle GHE=m\angle DFH[/tex]

Replacing the given expressions, we have

[tex]x+52=96-10x[/tex]

Let's solve for x

[tex]\begin{gathered} x+10x=96-52 \\ 11x=44 \\ x=\frac{44}{11} \\ x=4 \end{gathered}[/tex]

Answers

Prediction of the mean value of the dependent variable y for values of the independent variables x 1, x 2, . . . , x q that are outside the experimental range is called extrapolation of data.

What is extrapolation of data?

In statistics and mathematics, especially in the branch of data-science it is quite common to use a range of values from a parameter to predict the values of the dependent variable.

One of the most common applications of this is regression equations, when pairs of one of the independent variables with the dependent variable are used to predict the dependent variable.

In the case of this problem, we want to predict the dependent variable, but with values that are outside the experimental range, hence we extrapolate the data inside the experimental range for values that are outside the experimental range.

Distance between M(6,-7) and a line that contains the points C(-6,-2) and H(-1,10) is 7.846

First we will find the equation of the line containing the points C(-6,-2) and H(-1,10).

Take (x₁, y₁) = (-6,-2) and (x₂, y₂) = (-1,10).

Then the slope of the line, m = y₂-y₁/x₂-x₁

                                           = 10- -2/-1- -6

                                           = -12/7

So the equation of the line is

y-y₁ = m(x-x₁)

⇒ y- -2 = -12/7(x- -6)

⇒ y+2 = -12/7(x+6)

⇒7(y+2) = -12(x+6)

⇒ 7y +14 = -12x -72

⇒ 12x+7y +14+72 = 0

⇒ 12x+7y+86 = 0

This is in the form ax+ by+ c = 0

Also given the point (x, y) = (6, -7).

Distance between a point (x, y) and a line ax+ by+ c = 0 is,

[tex]\frac{|ax+by+c|}{\sqrt{a^2+b^2} }[/tex].

So Distance between M(6,-7)  and the line 12x+7y+86 = 0 is

[tex]\frac{|12.6+7.-7+86|}{\sqrt{12^2+7^2} }[/tex] = |72-49+86|/√(144+49)

                    = 109/√193

What is a circle?

All points in a plane that are at a specific distance from a specific point, the center, form a circle. In other words, it is the curve that a moving point in a plane draws to keep its distance from a specific point constant. The radius of a circle is  separation between any point on the circle and its center. The radius must typically be a positive integer. A degenerate case is a circle with r=0. Except when otherwise specified, this article discusses circles in Euclidean geometry, namely the Euclidean plane.

A circle, specifically, is a straightforward closed curve that separates the plane into its inner and exterior. In common parlance, the word "circle" can apply to either the figure's boundary or its entirety, including its inside; in rigorous technical parlance, the circle only refers to the boundary and the entire shape is referred to as a disc.

A circle can also be described as a particular type of ellipse where the semi-major and semi-minor axes are equal, the eccentricity is 0, and the two foci are coincident, or as the two-dimensional shape with the greatest area per unit perimeter squared when applying calculus of variations.

if, diameter= 90 inches

radius = 90/2= 45inches

area= [tex]\pi r^{2}[/tex]

       = 3.14* 45* 45

Answer:

(f∘g)(12) = 24

Step-by-step explanation:

Pre-Solving

We are given the functions f(x)=4x+8 and [tex]g(x)=\sqrt{x+4}[/tex]. We want to find (f∘g)(12).

(f∘g)(12) means that we first find the value of g(12), and then plug that value into f(x).

Solving

First, we find g(12). To do this, substitute x as 12.

[tex]g(12) = \sqrt{12 + 4}[/tex]

Add 12 and 4 together under the radical.

[tex]g(12) = \sqrt{16}[/tex]

Take the square root of 16.

g(12) = 4

Now, substitute 4 as x in f(x) = 4x + 8.

f(4) = 4(4) + 8

Multiply.

f(4) = 16 + 8

Add 16 and 8 together.

f(4) = 24

f(4) has the same value as (f∘g)(12), since 4 is the value of (g)(12), and then the value of g(12) was plugged in as x in f(x).

Therefore, (f∘g)(12) is 24.

The percent of pizzas that are less than 12.04 inches is 56.36%

Given the following:

Mean, μ=12

Standard deviation, σ=0.25

Percent of pizzas less than 12.04:

Let P(X<12.04) be percent of pizzas less than 12.04

P(X<12.04)=P(Z<(x-μ)/σ)

               =P(Z<(12.04-12)/0.25)

               =P(Z<0.16)

Z-value of 0.16 from cumulative standardized normal distribution is 0.5636

Given that P(X<12.04)=P(Z<0.16), and P(Z<0.16) from normal distribution table is 0.5636,

P(X<12.04)=P(Z<0.16)=0.5636

P(X<12.04)=0.5636
