Randy collected two different data sets and labeled them data set Q and data set R. Data set Q has a correlation coefficient of −0.87,
and data set R has a correlation coefficient of −0.96.

Part A: Which data set has a stronger linear relationship?

Part B: How do you know this?

Select two answers, one for Part A and one for Part B

Answers

Answer 1

Answer:

Part A: Data set R

Part B: The correlation coefficient ranges from -1 to 1, where -1 represents a strong negative correlation and 1 represents a strong positive correlation. Data set R has a correlation coefficient of -.96, which has an absolute value that is closer to 1 than Data set Q's -.87, which means that it has a stronger linear relationship.

Answer 2

The data set R has a stronger linear relationship because the value of correlation coefficient is close to -1.

What is correlation?

It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.

[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]

We have:

Correlation coefficient for data set Q = -0.87

Correlation coefficient for data set R = -0.96

The data set R has a stronger linear relationship because the value of correlation coefficient is -0.96 which is close to -1.

As we know the correlation coefficient varies between -1 to +1 when the value of correlation coefficient is close to -1 or +1 the relationship is strong.

Thus, the data set R has a stronger linear relationship because the value of correlation coefficient is close to -1.

Solve each system of equations.
2x- 4y = 20
x=4

Answers

Answer:

(x,y)=(4,-3)

Step-by-step explanation:

2x- 4y = 20

x=4

Substitute the value of x

2*4-4y=20

Solve equation

y=-3

A possible solution is

(x,y)=(4,-3)

Check the solution

2*4-4*(-3)=20

4=4

Simplify

20=20

4=4

The ordered pair is the solution

The solution of the given system of equations is y = -3.

What is the equation?

A formula known as an equation uses the same sign to denote the equality of two expressions.

In another word, the equation must be constrained with some constraints.

For example 5x + 4y = -8

Given the set of equations,

2x- 4y = 20

x=4

By substitution,

2(4) - 4y = 20

8 - 4y = 20

-4y = 20 - 8

-4y = 12

By multiplying by -1 both sides

4y = -12

By dividing 4 both sides

y = -3

Hence "The solution of the given system of equations is y = -3".

Tiffany is filling her daughter’s pool with water from a hose. She can fill the pool at a rate of 1/10 gallon/seconds.How many gallons of water can she fill in 50 seconds

Answers

Answer:

5 gallons

Step-by-step explanation:

If she can do 1/10 gallon per seconds, that means she can do 5/50.

You can write it as this ratio:

1/10 = x/50.

You know that 10 * 5 = 50.

Since it is a constant ratio, it has to be 1 * 5 = x

Since 1 * 5 = 5, Tiffany can fill the pool 5 gallons per 50 seconds.

Actually Welcome to the Concept of the Trigonometry.

here, we use the Linear pair property of the adjacent angles.

We know that, all the adjacent angles in a linear pair add to get 180°

so we get as,

=> (n+6) +90°+(2n+3) =180°

=> (n+6) +(2n+3) =180-90

=> 3n+9 = 90

=> 3n= 90-9

=> 3n = 81

hence, n = 81/3

=> n = 27°

thus the value of n is 27° .

Jerry scored 581 points by collecting 7 coins. In all, how many coins does Jerry have to collect to score a total of 996 points? Solve using unit rates.

Answers

Answer:

12 coins

Step-by-step explanation:

Points scored by collecting 7 coins = 581

Number of coins required to collect 996 points

Let Number of coins = c

7 coins = 581 points

c coins = 996 points

Cross multiply :

581 * c = 996 * 7

581c = 6972

Divide both sides by 581

581c / 581 = 6972 / 581

c = 12

Hence, number of coins required to collect 996 points is 12
