Find the Discount % if the OriginalPrice is $15 and the Sale Price is $14.25.

Answer:

1921 books remaining.

Step-by-step explanation:

This library is fairly organized, so each shelf only has 14 books. Now with 202 shelves, we multiple the shelves by the amount of books per shelf.

202x14=2,828

Now, with 2828 books in the library before being checked out, we need to find out how many books left after the students came.

2828-907=1,921

The answer is 1,921 books remaining.

Hope this helps!

Answer:

The weight of each gaming machine be 14 pounds and that of DVD is 6 pounds.

Step-by-step explanation:

Let the weight of the gaming machine be x and that of DVD be y. ATQ,

3x+y = 48 .....(1)

3x+5y = 72 .....(2)

Subtract equation (2) from (1)

3x+y-(3x+5y) = 48 -72

y-5y = -24

-4y = -24

y = 6

Put the value of y in equation (1).

3x+6 = 48

3x = 42

x = 14

So, the weight of each gaming machine be 14 pounds and that of DVD is 6 pounds.

Answer:

DVD box weighs 6 pounds and gaming machine box weighs 14 pounds

What is line of best fit and correlation coefficient?

A straight line that best approximates the given set of data is known as a line of best fit. It is a line that, on a graph, roughly straddles the center of each scatter point. The association is stronger the closer the points are to the line of greatest fit.

The equation of a line of a best fit is represented as: y=mx + c

To gauge how closely two variables are related to one another, correlation coefficients are used.

Solution:

In order to determine how closely related two sets of data are, correlation coefficient formulas are used. The formulas provide a value in the range of -1 and 1, where

The strength of the link between the variables increases with the distance between the coefficients of +1.0 and -1.0.

-0.9 is a value which is greater than -0.8, so the values which are greater than -0.8 are not considered as strong correlation coefficient.

Whereas the values which are less than 0.8 are also not considered as strong coefficients.

Hence 0.8 is the correlation coefficient which represents the strongest linear relationship.

Answer:

25inch

Step-by-step explanation:

Ok so there is something called a Pythagorean theorem.

It's a²+b²=c²

It works on right triangles

C is the longest side or the side not touching the right angle

and a and b is the other 2 sides

so the missing side is 24²+7²=Missing side or c²

24²=576 and 7²= 49  

576+49=625

The coordinates of point B on segment AC such that the ratio of AB to BC is 2 : 3 is (12 / 5, 38 / 5).

In this problem we must use the concept of segment ratios and linear algebra operations to determine the location of a point within a line segment generated by two distinct points:

B(x, y) = A(x, y) + (AB / AC) · [C(x, y) - A(x, y)]

B(x, y) = (0, 4) + (2 / 5) · [(6, 13) - (0, 4)]

B(x, y) = (0, 4) + (2 / 5) · (6, 9)

B(x, y) = (0, 4) + (12 / 5, 18 / 5)

B(x, y) = (12 / 5, 38 / 5)

The coordinates of point B on segment AC such that the ratio of AB to BC is 2 : 3 is (12 / 5, 38 / 5).

The statement is incomplete, complete form is shown below:

Answer:

[tex]a=\dfrac{4x-7}{x}[/tex]

Step-by-step explanation:

The equations of lines are :

y=4x-5 and y=ax+2

From above equations,

4x-5 = ax+2

4x-ax = 5+2

4x-7 = ax

[tex]a=\dfrac{4x-7}{x}[/tex]

So, the value of a is equal to [tex]\dfrac{4x-7}{x}[/tex].

Answer:

315.1*

Step-by-step explanation:

The value of 5.5 radians into degree is 315⁰.

The radian, denoted by the symbol rad, is the SI unit for measuring angles, and is the standard unit of angular measure used in many areas of mathematics.

Conversion of radian to degree = radian X 180⁰/π

Now,

Degree = 5.5 X 180⁰ X 7/22

            =  6930/22

          = 315⁰

Thus, the value of 5.5 radians into degree is 315⁰.

Answer:

C. 3(2x + 5y) is the algebraic expression equivalent to the expression

Step-by-step explanation:

From the question, the given expression is 6x + 15y.

Factorizing this expression gives 3(2x + 5y). Hence, the algebraic expression equivalent to the expression 6x + 15y is 3(2x + 5y). (Option C).

Checking the remaining options

A. 3(2x - 5y)

Expanding this gives 6x - 15y. It is not equivalent to the given expression

B. 3(5x - 2y)

Expanding this gives 15x - 6y. It is not equivalent to the given expression

D. 3(5x + 2y)

Expanding this gives 15x + 3y. It is not equivalent to the given expression.

Hence, C. 3(2x + 5y) is the algebraic expression equivalent to the expression.

Step-by-step explanation:

The equation of a circle in standard form is

Here (h, k ) = (- 5, 1) and r = 2, then

(x - (- 5))² + (y - 1)² = 2² , that is
