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.

Beth travels at an average speed of 30 mph for 20 miles.
Without stopping, Beth then travels 70 miles in 1.5 hours.
Find her average speed for the entire journey to 2 dp.
Answer:
41.54 mph
Step-by-step explanation:
you need to find the total distanceand total time to find the average speed
use distance/time = speed equation
time = 1.5 hours + 40 mins = 2 hours 10 mins
distance= 20 + 70 = 90 miles
90/130 mins x 60 = 41.54 mph

200 people got an email 37 people clicked on it how do you get 18.5%
Answer:
37/200
Step-by-step explanation:
Event/Sample Space = .185 = 18.5%
Answer:
Step-by-step explanation:
If 37 people out of 200 people opened an e-mail, you can write it as 37/200.
The number above the bar is the numerator: 37
The number below the bar is the denominator: 200
Divide the numerator by the denominator to get fraction's value:
Val = 37 ÷ 200
Val = 0.185
To calculate the percent value:
0.185 = (Calculate fraction's value.)
0.185 × 100/100 =
(0.185 × 100)/100 = (Multiply that number by 100.)
18.5/100 =
18.5%; (Add the percent sign % to it.)
So that's how you get 18.5%
PLEASE HELP ME IM DOING A TEST :Write in point-slope form an equation of the line that passes through the point (5, 9) with slope 7. ____
Answer:
y-9+7(x-5)
Step-by-step explanation:
y - x1 = m ( x - y1 )
Y1 = 9
x1 = 5
m=slope (in this case 7)

[7x-y-26=0]
Step-by-step explanation:
point slope form =
y-y1=m(x-x1)

y-9=7(x-5)
=
[7x-y-26=0]
you may want the y-9=7(x-5) as your answer
second part of this is for vertex form

y is equal to 9
x is equal to 5

Answer:
is this algebra
Step-by-step explanation:
Answer:
1.)
A.) The graph does represent a proportional relationship because if you calculate the slope, it's 2/3, which is consistent throughout the line and with the given points.
Slope calculation:
[tex]\frac{y2-y1}{x2-x1} \\\\\frac{6-4}{9-6} \\\\\frac{2}{3}[/tex]
B.) The coordinate (0,0) represents that no laps have been completed nor has the time started
C.) The coordinate I chose is (6,4). It represents that 4 laps were completed in 6 minutes
2.) The values to represent a proportional relationship because once calculating the slope, which is 13, you can try it with other points. Even though there's some values missing between (6,78) and (10,130), the slope remains the same.
Slope Calculation:
[tex]\frac{y2-y1}{x2-x1} \\\\\frac{130-39}{10-3} \\\\\frac{91}{7} \\\\\frac{13}{1}[/tex]
3.)
A.) The constant of proportionality is 7/4 or 1.75
B.) y = 7/4x
4.) She'll run 8 miles because since 3/4 of an hour equates to 6 miles and there's 1/4 missing, 2 miles is 1/3 of 6 miles and 1/4 is 1/3 of 3/4 , so 1/4+1/4+1/4 = 3/4. She can run 8 miles (4*2) in 1 hour (4*1/4 hour)

Answer:
yes, the point (-1, 5) is in the solution set
Step-by-step explanation:
y ≥ 2x + 3
Is 5 ≥ 2(-1) + 3? Yes
y + x > 0
Is 5 + (-1) > 0? Yes
Answer:
Yes the Point (-1,5) is in the solution set.
Step-by-step explanation:
Well you have to sub in the x and the y.
In the first equation
5 >= 2(-1) +3 = 5>= 1 So this one is true and in the set.
The second one
5+-1>0 = 4>0. So this one is also true.

[Help Asap, Will Mark Brainliest] Question is in the image.
Answer:
y = 30
z = 115
Step-by-step explanation:
z° + 65° = 180°
(Exterior Angles on the same side of transversal)
z° = 180° - 65°
z° = 115°
z = 115
(5y - 85)° + z° = 180°
(Linear pair angles)
(5y - 85)° + 115° = 180°
(5y - 85)° = 180° - 115°
(5y - 85)° = 65°
5y - 85 = 65
5y = 65 + 85
5y = 150
y = 150/5
y = 30

so 8*6=48, so we know that (4*6)+(_*6) should equal 48.
4*6=24
subtract 24 by 48 and we get 24.
now you probably know that it equals 4, but to be sure, divide 24 by 6, and you'll get 4.
Answer:
From top to bottom:
1st box: 4
2nd box: 24
3rd box: 48
Step-by-step explanation:
So, based on my knowledge, you are learning the Distributive probability. So, what the Distributive property does is it basically allows to distribute the one of the numbers in the multiplication problem. In this problem, we can see that the 8 is being distributed into two groups of 4 to make (4 * 6) + (4 * 6). Then, we solve the things in the two parenthesis, making 24 + 24. Now, all we have to do is add 24 + 24, making 48.

Answer:
27
Step-by-step explanation:
The number that lies halfway between 16 and 38 is 27.
What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9.
We have to determine the number that lies halfway between 16 and 38.
This is calculated by finding the average (or mean) of the two numbers. To do this, add the numbers together (16 + 38) and divide by 2.
⇒ 54/2
The result is 27.
Thus, the number that lies halfway between 16 and 38 is 27.

Find the missing side of this right
triangle.

X
15
x=
Answer:
We can fine x by using the pythagoras formula
a²+b² = c²
Which C is X
And
a= 17
b= 15
So
a² + b² = c²
(17)² + (15)² = c²
289 + 225 = c²
514 = c²
√514 = c
22.67 = c
So basically X is (22.671)
The missing side of the given right angled triangle is 8 units.
In the given right angled triangle, the hypotenuse side is 17 units, base is 15 units and the height is x units.
By using Pythagoras theorem, we get
17²=15²+x²
289=225+x²
x²=289-225
x²=64
x=√64
x=8 units.
Therefore, the missing side of the given right angled triangle is 8 units.
