Let's assign John and Alex's points a variable.
John's Points: 2x-1
Alex Points: x
Now, let's set up an equation.
x+2x-1=23
Simplify.
3x-1=23
3x=23+1=24
3x=24
Now, to find x, or Alex's score, we divide.
24/3=8
Alex's Points= 8
Johns Points= (8*2)-1=15

Answer:
1. Data point A
4. Data point D
Step-by-step explanation:
In a scatter plot, the closer the clustered data points are close to the best line of fit, the greater the correlation that would exist between the two variables.
If we are to draw a best line of fit in the scatter plot that is shown above, the closest data points amongst data points A, B, C, D, and E, that would be close to the best line of fit are data points A and D.
Therefore, removing data point A and point D would cause the correlation to decrease the most.
Answer:x=7
Step-by-step explanation:
x=7
90-55=35
5x=35
x=7
<h3>Given</h3>
a cuboid with length, width, height dimensions 5, 6, x
<h3>Find</h3>
the value of x that makes the numerical value of the total surface area equal to the numerical value of the volume
<h3>Solution</h3>
The volume is given by
... V = L·W·H = 5·6·x = 30x
The area is given by
... A = 2(L·W + H(L+W)) = 2(5·6 +x(5+6)) = 2(30 +11x) = 60 +22x
When these are equal, we have
... 30x = 60 +22x
... 8x = 60
... x = 7.5
The desired value of x is 7.5.
The change in grandpa Ernie's height each year is equal to 0.6cm.
As given in the question,
Number of years for which grandpa's height is shrinking = 4 years
The total decrease in height after four years is equal to 2.4cm.
Let x represents the decrease in height each year
The required equation to calculate decrease in height each year is given by:
4x = 2.4
⇒ x= 2.4 /4
⇒x = 0.6cm
Therefore, the change in grandpa Ernie's height each year is equal to 0.6cm.
The complete question is :
Grandpa Ernie is shrinking over the past four years his height decreased by a total of 2.4 cm it decrease by the same amount each year what was the change in grandpa Ernie’s height each year.
