A list has 80 numbers, of which the largest is 768. Suppose that the 768 is replaced by 868. Does the median of the list change? If yes, how much? If no, why not? Does the mean change? If yes, how much? If no, why not? ·Does the 10% trimmed mean change? If yes, how much? If no, why not?

Answers

Answer 1

Median may change by 100, mean changes by at most 100, 10% trimmed mean does not change.

How does replacing the largest number affect the median, mean, and 10% trimmed mean?

Replacing the largest number in a list of 80 numbers from 768 to 868 will result in a change in the median and the mean, but not in the 10% trimmed mean.

The median will increase by 100 since it is the middle number when the list is sorted, and replacing the largest number will shift the original largest number down by one position.

The mean may change by at most 100, as the change in the largest number is divided among all the numbers in the list, so the effect on the mean depends on the distribution of the numbers in the list. The 10% trimmed mean does not change since it removes the top and bottom 10% of the data, regardless of the values in those positions.

So looking at the picture, we can see 5 triangles, therefore :

or, -4p = - 14

or, p = -14/-4

or, p = 7/2 = 3.5

Answer:

p = 3.5

Step-by-step explanation:

What you would do to get p is subtract 5 from both sides of the equation to leave the number and p, THEN divide both sides by the numerator of -4.

-4p + 9 = -5

Answer:

Step-by-step explanation:

because angle a and angle b are complementary they equal 90 degrees in total

a+b=90

since angle a = 59°

Liz's math test included a survey question asking how many hours students spent studying for the test. The scatterplot and regression line below show the relationship between how many hours students spent studying and their score on the test.

The fitted line has a slope of 15.

What is the best interpretation of this slope?

Answer:

C.)

The model predicts that the score will increase 15 points for each additional hour of study time.

Step-by-step explanation:

The slope of a regression line represents the rate of change :

From the formula :

Rise / Run = (y2 - y1) / (x2 - x1).

The slope is a Coefficient which shows how much the dependent variable changes per unit change in the independent variable.

Hence, for a slope value of +15, which is positive, meaning an increase ; then the score obtained will increase by 15 per additional unit increase in hour of study.

For Question 13 : 1 = 130°; 2 = 50° 3 = 130°

For Question 14 : 1 = 65°; 2 = 115° 3 = 65°

Step-by-step explanation:

Question 13:

There is multiple ways to solve those questions. However I will stick with the simple way.

1) We know that a straighteangle is = to 180°

2) Acording to the statment on step one we will say that 1 + the 50° = 180°

Resoectivelly

180° - 50° = 1

180° - 50° = 130°

1 = 130°

3) 2 + 1 = 180°

We already 1 from step 2, then

2 = 180° - 130°(1)

2 = 50°

4) 2 + 3 = 180°

3 = 180° -  50° ( 2)

3 = 130°

Question 14 1) We know that a straighteangle is = to 180°

2) Acording to the statment on step one we will say that

angle 1 + the angle  115° = 180°

Resopectivelly

180° - 115° = 1

180° - 50° = 65°

1 = 65°

3) 2 + 1 = 180°

We already 1 from step 2, then

2 = 180° - 65°(1)

2 = 115°

4) 2 + 3 = 180°

3 = 180° -  115° ( 2)

Answer:

He used 6 bananas at .50 which cost $3.00

12 oranges at .75 which cost $9.00 and

3 papayas at $1.25 which cost $3.75

Step-by-step explanation:

We can set up a system of equations using the information given.

b for banana, r for orange, p for papaya

b + r + p = 21. Also given r = 2b So substitute to simplify for calculating two unknowns:

b + 2b + p = 21 The number of items.

50b + 75(2b) +125p = 1575 The cost.

I multiplied everything by 100 to eliminate the decimals.

To solve by substituion, rewrite the first equation to get a value for p in terms of b

p = 21 - 3b

Substitute this value in the second equation and solve for b.

50b + 150b + 125(21–3b) = 1575

200b +2625 –375b = 1575 Subtract 2625 from both sides and combine the like terms:

–175b = 1575 –2625

–175b = –1050. Divide both sides by –175

b = 6

Substitute in the original equation to find the amount of each fruit:

b + r + p = 21

b = 6 bananas

r = 2b. 2(6) = 12 oranges. I used r so as not to mix up o with 0.

6 + 12 + p = 21

p = 21 –18

p = 3 papayas
