Given:

20$

DVD cost = 32$

Friend’s loan = 12$ (since he loaned you enough money to be able to pay for the DVD)

Find:

available funds after you buy the DVD = ?

Solution:

First, we add your current funds with the money your friend loaned you:

20$ + 12 $ (we will assume this amount since the problem states that he loaned you just enough money to pay for the DVD) = 32$

Next, we subtract the total amount of the DVD cost to the total amount of money you have right now:

$32 (DVD cost) - $32 (your total funds) = $0

Therefore, your available funds after buying the DVD is $0. But if we will take into consideration the amount you loaned from your friend by subtracting it to your remaining funds, then you’ll have $0 - $12 = $-12, which is your debt.

teacher gives 5 students a multiple choice test, in which each problem is worth 1 point and there is no penalty with negative po

mamaluj [8]

The mean is the average value of a given set of numbers, and the median is the number in the middle of a set of numbers arranged in increasing order

The correct values as response to the questions are;

The minimum possible top score is 21

The maximum possible top score is 32

The minimum of the possible standard deviation is approximately 1.26

The maximum of the possible standard deviation is approximately 11.7

The reason the above values are correct are as follows:

The given parameters are;

The number of students that take the test, n = 5

The amount of points for each problem = 1 point

The median score = 9

The mean Score = 10

Required:

The minimum possible score;

The maximum possible top score

The minimum of the possible standard deviations

The maximum of the possible standard deviations

Solution:

Given that there is a score (the median) which is 9, we have;

The scores obtainable in the test is Scores ≥ 9

Therefore, for a score of 10, we have;

The minimum total points obtainable = Mean × Number of students

Therefore;

Total minimum total points obtainable by the 5 students = 5 × 10 = 50

The minimum possible top score

By arrangement, with the median at the middle, the minimum possible top score is given as follows;

0, 0, 9, 20, 21

Therefore, the minimum possible top score is 21

The maximum possible top score

The maximum possible top score is similarly given by arrangement of the numbers as follows'

0, 0, 9, 9, 32

The maximum possible top score is 32

The minimum standard deviation

By arrangement and selection, the minimum standard deviation is given as follows;

The minimum of the possible standard deviations of (9, 9, 9, 11, 12) ≈ 1.26

The maximum of the possible standard deviation

The maximum of the possible standard deviation is given as follows;

The maximum of the possible standard deviation of (0, 0, 9, 9, 32) ≈ 11.7

What is a negative 3 cubed written as a fraction

Advocard [28]

When you have an exponent that is negative, it means to take reciprocal of the fraction then take it the power.

Some examples:

5^-2 = 1/5^2 = 1/25
10^-3 = 1/10^-3 = 1/1000

Which of the following could not be a value of n? side lengths of 9 and 13

daser333 [38]

The correct answer here would be D. And that is because, in a triangle, the sum of 2 of the sides has to be greater than the third side for all sides. If we add 22 and 13 we get 35, and 35 is greater than 9, for sure. But if we add 13 and 9 we get 22 which is not greater than the third side length of 22; it would be collinear with the side length and it has to be greater than the side length.
