The correlation coefficient r between the size of a lake in square miles, x, and the yearly number of registered boaters, y, is 0.743. What percent of the variation in the number of yearly boaters can be explained by differences in lake sizes? A.74.3% B.55.2% C.44.8% D.37.2% Algebra
The variation in any sample group is simply the square of the correlation coefficient, that is:
variation = r^2
Therefore given an r value, we can simply directly calculate for variation percentage.
variation = (0.743)^2
variation = 0.552 or 55.2%
Answer:
B. 55.2%

the length of a cube is x centimeters. If x is an integer why can't the volume of the cube equal 15 cm cubed
The volume of a cube with a side length of x centimeters cannot equal 15 cm³ when x is an integer.
Explanation:The question asks why the volume of a cube with a length of x centimeters cannot equal 15 cm³ when x is an integer. In order to calculate the volume of a cube, we use the formula V = s³, where V represents the volume and s represents the length of a side. If x is an integer, the length of the cube can be any integer value.
However, when we substitute x = 15 into the formula, we find that the volume of the cube would be 15³ = 3375 cm³, which is not equal to 15 cm³. Therefore, the volume of a cube with a side length of x centimeters cannot equal 15 cm³ when x is an integer.

How do you solve the system of linear equation by multiplying?
5x - 2y = 11
3x + 5y = 19
The solution set for the system of equations is (3, 2).
What is system of equations?In mathematics, a set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought
Given is the system of equations -
5x - 2y = 11
3x + 5y = 19
Multiply Eq.{1} by 3 and Eq.{2} by 5, we get -
15x - 6y = 33
15x + 25y = 95
Now, performing Eq(2) - Eq(1), we get -
15x + 25y - 15x + 6y = 95 - 33
31y = 62
y = 2
x = 11 + 2y/5
x = 15/5
x = 3
Therefore, the solution set for the system of equations is (3, 2).

The length of a rectangle is 5cm more than its width. The perimeter of the rectangle is 46cm. Find the width and the length
The width of the rectangle is 9 cm, and the length is 14 cm.
Explanation:To find the width and length of the rectangle:
Let's assume that the width of the rectangle is x cm. According to the problem, the length of the rectangle is 5 cm more than its width, so the length would be x + 5 cm.
The perimeter of the rectangle is 46 cm. The formula for the perimeter of a rectangle is P = 2(w + l), where P is the perimeter, w is the width, and l is the length.
So, we can set up the equation: 46 = 2(x + (x + 5)).
Simplifying the equation gives us: 46 = 2(2x + 5).
Expanding the equation further gives us: 46 = 4x + 10.
Subtracting 10 from both sides of the equation gives us: 36 = 4x.
Dividing both sides of the equation by 4 gives us: x = 9.
Therefore, the width of the rectangle is 9 cm, and the length is 9 + 5 = 14 cm.
To find the width and length of the rectangle, set up an equation using the given information and solve for x. The width is 9 cm and the length is 14 cm.
Explanation:To solve this problem, we can set up an equation using the information given. Let's assume the width of the rectangle is x cm. Since the length is 5cm more than the width, it will be x + 5 cm. The perimeter of a rectangle is found by adding all its sides, so we have:
2(x + x + 5) = 46
Simplifying this equation gives us:
4x + 10 = 46
Subtracting 10 from both sides:
4x = 36
Dividing both sides by 4:
x = 9
Therefore, the width of the rectangle is 9 cm and the length is 9 + 5 = 14 cm.

find least common denominator and rewrite the fractions
lets use 24: 24/3 = 8, 24/4 = 6, 24/8 = 3
so 2/3 = 16/24
1/4 = 6/24
4/8 = 12/24
now add them together:
16/24 + 6/24 + 12/24 = 34/24 which becomes 1 and 10/24 reducing to 1 and 5/12

The coordinates of quadrilateral EFGH are E(4, 8), F(1, 2), G(6, 1), and H(8, 8). The image of EFGH under dilation is E'F'G'H'.
If the coordinates of vertex E' are (1, 2), what are the coordinates of vertex H'?
No pic is attached
A) (2, 8)
B) (5, 6)
C) (2, 2)
D) (4, 8)
E goes from (4,8) to (1,2) which equals a 1/4 scale factor ( put lower number over higher number so X = 1/4 and Y = 2/8 which reduces to 1/4)
so H needs to be reduced by 1/4
8/4 = 2
so new coordinate is (2,2)
