The number of wins for a high school football team is measured for the season. When the team plays at home, it is generally believed that they will win. Comparing the location of the game and the number of wins, a correlation coefficient of −0.91 is calculated. What would this imply about the football team winning at home?
1. The scatter plot would closely resemble a straight line with a negative slope. The data has a strong, negative correlation, and a causal relationship exists between the team playing at home and winning.
2.The scatter plot would closely resemble a straight line with a negative slope. The data has a strong, negative correlation, but causation cannot be determined.
3.The scatter plot would not be represented by a line of best fit with a negative slope. There is a weak correlation between the football team playing at home and winning.
4. There is no causation and almost no correlation between the football team playing at home and winning.
Correlation coefficients are used to solve this question, leading to the following answer:
1. The scatter plot would closely resemble a straight line with a negative slope. The data has a strong, negative correlation, and a causal relationship exists between the team playing at home and winning.
-----------------------------------
Correlation coefficients:
They measure the relationship between variables, the closer |r| is to 1, the stronger the relationship is.
If the coefficient is positive, there is a positive relationship(both variables change in the same direction)If the coefficient is negative, there is a negative relationship(the variables change in opposite directions).-----------------------------------
In this question:
r = -0.91
Negative, so opposite directions, which can be explained as for example, the more the team travels(plays away games), the less games it wins.|r| = 0.91, which is quite close to 1, so a significant relationship.Negative relation means that the scatter plot would be represented by a straight line with a negative slope, and the correct answer is:1. The scatter plot would closely resemble a straight line with a negative slope. The data has a strong, negative correlation, and a causal relationship exists between the team playing at home and winning.

13. Each side of a rhombus is 14 in. long. Two of the sides form a 60 angle. Find the area of the rhombus. Round your answer to the nearest square inch.
Answer:
170 in²
Step-by-step explanation:
Given that :
Side, a = 14 in
Angle formed =? 60°
Take height, = l
The ratio of height to side = Sine of the angle formed
l /s = Sine 60°
Sin 60 = sqrt(3)/2
l/s = sqrt(3)/2
l = sqrt(3)/2 * s
s = 14
l = 14 * sqrt(3)/2
l = 7sqrt(3)
Area of rhombus :
l * s
7sqrt(3) * 14
= 169.74097
= 169.74 in²
= 170 (nearest square inch)

How do you graph an equation if you had m= -1/3 and b = 2.
Answer:
You first plot the point (0,2), then when the x-value of the graph increases by 3, decrease the y-value of the graph by 1, and when the x-value o the graph decreases by 3, increase the y-value of the graph by 1.
Step-by-step explanation:
The equation would be [tex]y = -\frac{1}{3}x+2[/tex]. To graph it, you first need to find the y-intercept, which is the coordinate on the line when the x-value equals 0. If x = 0, [tex]y = -\frac{1}{3}x+2[/tex] would become [tex]y = 2[/tex] since anything multiplied by 0 would become 0. Now you've located the y-intercept, which is (0, 2). The slope of a line is the coefficient of the variable x. Since the slope is a negative number, the line will go downwards as it increases its x-value and goes upward as it decreases its x-value. A slope of [tex]-\frac{1}{3}[/tex] would mean that when the x-value increases by 3, the line's y-value will decrease by 1. And when the x-value decreases by 3, the line's y-value will increase by 1. An x-value increase of 6 would be a decrease of 2, and so on. Two other obvious points on the line would be (6,0) and (3, 1).

The correct number line should look like the one on the right in the image provided, with an open circle at 5 and the line shaded to the left of 5. Option B is correct.
What is a number line?A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.
Here,
To solve -5x + 10 > -15, we can start by subtracting 10 from both sides to get,
-5x > -25
Next, we can divide both sides by -5, remembering to flip the inequality sign because we're dividing by a negative number:
x < 5
This tells us that any number less than 5 will make the inequality true. So on the number line, we want to shade all the numbers to the left of 5.
The correct number line should look like the one on the right in the image provided, with an open circle at 5 and the line shaded to the left of 5. Option B is correct.

Explain how to solve the equation 2x+4=-6x+38 in complete sentences. Your response needs to be a paragraph in length and use appropriate math vocabulary
Answer:
×=17/4
Step-by-step explanation:
The equation 2x+ 4=-6x+38
First of all you collect like terms by moving the number -6x over to the left hand side which then becomes +6x as it crosses the equal to sign, likewise you move +4 over to the right hand side which then becomes -4. The equation is now 2x+6x=38-4, which when solved gives 8x=34. X is then made subject of formula by dividing both sides by 8 therefore x=34/8 which when reduced to the lowest term is 17/4

$2.40 x 40 =
$96
Hope that helps!
The solution is $ 96
The cost of 40 pints of ice cream is given by the equation A = $ 96
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the cost of 40 pints of ice cream be A
Now , the equation will be
The cost of 6 pints of ice cream = $ 14.40
So , the cost of 1 pint of ice cream = cost of 6 pints of ice cream / 6
Substituting the values in the equation , we get
The cost of 1 pint of ice cream = 14.40 / 6
The cost of 1 pint of ice cream = $ 2.40
Now ,
The cost of 40 pints of ice cream A = 40 x cost of 1 pint of ice cream
Substituting the values in the equation , we get
The cost of 40 pints of ice cream A = 40 x 2.40
The cost of 40 pints of ice cream A = $ 96
Therefore , the value of A is $ 96
Hence , the cost is $ 96
