The mean difference in the game scores over six games is 2.5

The mean difference measures the absolute difference between the mean value in two different groups.

Given is a basketball team which played six games such that in those games, the team won by 8 points, lost by 11, won by 7, won by 11, lost by 4, and won by 13 respectively.

The mean difference of the given data can be calculated using the following formula -

Mean Difference = (∑W / n) - (∑L / n)

Where -

(∑W / n) is the mean of games won.

and

(∑L / n) is the mean of games lost.

(∑W / n) = (8 + 7 + 11 + 13)/4 = 9.75

and

(∑L / n) = (11 + 4)/2 = 15/2 = 7.5

Mean difference =  (∑W / n) - (∑L / n) = 9.75 - 7.5 = 2.5

Therefore, the mean difference in the game scores over six games is 2.5

Answer:

Dia's age is 6.

Step-by-step explanation:

Tia's age= d

Dia's age= d-6

Therefore, after 10 years,

Dia's age= 2/3 Tia's age

Hence,

d-6+10=2/3(d+10)

d+4=2/3(d+10)

3/2(d)+4=d+10

3/2(d)-d=10-4

3d/2-2d/2=6

d/2=6

1/2(d)=6

d=6×2

d=12

Therefore,

Dia's age=d-6

=12-6

Answer:

Step-by-step explanation:

The coordinates of A will be at (-10, -5) when the transformation (x,y) → (x + 10, y + 5) is  performed on point A.

Given the coordinate of the resulting image after the transformation is A'(0, 0). We need to get the coordinate of the original image A.

Since the transformation (x,y) → (x + 10, y + 5) is performed on A.

A = (0 - 10, 0 - 5)

If we are going from the pre-image to the image, we will translate to the left and downwards

A = (-10, -5)

Hence the coordinates of A will be at (-10, -5)

if Figure ABCDE was reflected across the line y = x to create figure A'B'C'D'E' then (6, -2)  are the coordinates of the pre-image of E'.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Graph transformation is the process by which an existing graph, or graphed equation, is modified to produce a variation of the proceeding graph.

It's a common type of problem in algebra, specifically the modification of algebraic equations.

ABCDE was reflected across the line y = x to create figure A'B'C'D'E'.

The coordinates of the pre-image of E' are (6, -2)

Answer:

The expected value of the proposition is -$0.76.

Step-by-step explanation:

It is provided that a basketball player has made 291 out of 389 free throws.

Then rate of him making a free throw is,

[tex]P(\text{free throw})=\frac{291}{389}=0.7481[/tex]

The probability that he makes the next 2 free throws is:

[tex]P(\text{Next 2 free throws})=(0.7481)^{2}=0.5596[/tex]

The payout rules are:

Compute the expected value of the proposition as follows:

Expected value = $38 × P (Makes both) + (-$50) × P (Misses both)

                          [tex]=($38\times 0.5596)+(-$50\times (1-0.5596))\\=21.2648-22.02\\=-0.7552\\\approx -$0.76[/tex]

Thus, the expected value of the proposition is -$0.76.

8 parties

Step-by-step explanation:

First, find how much of her paycheck was from working 30 hours:

7.50(30)

= 225

Then, subtract this from 265, to find how much money was from bonuses:

265 - 225

= 40

To find how many parties she scheduled, divide 40 by 5, since each party she schedules gives her a $5 bonus:

40/5

= 8

So, she scheduled 8 parties

Answer:

it is 5

It is better to use the metric system, rather than the English system, in scientific measurement because,

The metric system uses one unit for each category of measurement.

A system of measurements is called the metric system. It is employed in calculations and research across the globe.

Measurements for length include millimeters (mm), decimeters (dm), centimeters (cm), meters (m), and kilometers (km).

A foot equals 30.48 cm, however, a popular 30 cm rule measures every 1 cm, therefore the metric system also provides more exact measurements.

The English system is in fact based on the metric system because they look for reference materials to get the measurements.

Answer:

m=10

Step-by-step explanation:

Answer:

m=10

Step-by-step explanation:

9(m+5)−3(m−2)=8m+31

Step 1: Simplify both sides of the equation.

9(m+5)−3(m−2)=8m+31

9m+45+−3m+6=8m+31

(9m+−3m)+(45+6)=8m+31(Combine Like Terms)

6m+51=8m+31

Step 2: Subtract 8m from both sides.

6m+51−8m=8m+31−8m

−2m+51=31

Step 3: Subtract 51 from both sides.

−2m+51−51=31−51

−2m=−20

Step 4: Divide both sides by -2.
