Use the given data to find the best predicted value of the response variable x. Ten pairs of data yield r=0.003 and the regression equation y=2+3x, and it is determined that is not a good model. Also, the mean of y values= 5.0. What is the predicted value of y for x=2
Answer:
Step-by-step explanation:
Given the regression equation :
y=2+3x
Mean of y values ; y = 5.0
Where y is the predicted variable ; x = predictor variable
The predicted value of y for X = 2

Step-by-step explanation:
Since AD bisects BC,
BD = DC.
Therefore 5x - 10 = 3x + 10 and x = 10.
Answer:
The value of x is 10.
Step-by-step explanation:
BD =CD
Which means
5x - 10 = 3x + 10
Let's solve.
[tex]5x - 10 = 3x + 10 \\ \frac{ - 3x \: \: \: \: \: = - 3x \: \: \: \: \: }{2x - 10 = 10} \\ \\ 2x - 10 = 10 \\ \frac{ \: \: \: \: \: \: \: \: \: + 10 = + 10}{2x = 20} \\ \\ \frac{2x}{2} = \frac{20}{2} \\ \\ x = 10[/tex]
Therefore, x = 10.
A set of 5 consecutive integers sums to 10. What are the integers?
Answer:
Let x be the smallest integer (the first integer)
1st: x, 2nd: x + 1, 3rd: x + 2, 4th: x + 3, 5th: x + 4
Hence,
x + x + 1 + x + 2 + x + 3 + x + 4 = 10
5x + 10 = 10
5x = 0
x = 0
Therefore, the answers are
0, 1, 2, 3, 4
Step-by-step explanation:
Integers include all positive integers, negative integers and 0.
0 is an integer but it is neither positive nor negative.

Answer
Angela transfers 15% of each paycheck she received into her savings account. If she transferred $54 into her savings account last week, how much did she earn on that paycheck? Show your work using a model, proportion or equation.
Answer:
She earned $360 on that paycheck.
Step-by-step explanation:
From the information given, you know that Angela transfers 15% of each paycheck and that she transferred $54 last week. With this, you can say that the amount she earned multiply for 15% is equal to 54, which you can express with the following equation:
0.15x=54, where x is the amount she earned on that paycheck.
Now, you can solve for x:
x=54/0.15
x=360
According to this, the answer is that she earned $360 on that paycheck.

If cm= (K2-15) in cm = (10k +9) in how many inches is cc
Answer:
Step-by-step explanation:
cm= (K2-15) in cm = (10k +9) in
K2 - 15 = 10k + 9
K2 - 10k = 9 + 15
K2 - 10k = 24
2k - 10k = 24
-8k = 24
k = - 3

Step-by-step explanation:
Store One:
$720(0.50)=$360
$720-$360=$360
Store Two:
$720(0.30)=$216
$720-$216=$504
$504(0.20)=$100.8
$504-$100.8=$403.2

SF of KP to KN = 4
If LM = 32, then we would have to divide 32 by 4 in order to get the missing length of KL.
32 ÷ 4 = 8
Length of KL = 8
Length of LM = 32
Length of KM = 32 + 8 = 40

the perimeter of a rectangle is (8x + 7y) feet, give two possible dimensions of the rectangle
please help ??
Answer:
Two possible dimensions of the rectangle are 4x and 7/2 y.
Step-by-step explanation:
The Perimeter of a Rectangle
It's given the perimeter of a rectangle is
P = 8x + 7y
The formula to calculate the perimeter of a rectangle of dimensions L and W is:
P = 2W + 2L
Equating term by term, we can guess two possible dimensions of the rectangle:
2W = 8x
Dividing by 2:
W = 4x
And also:
2L = 7y
Dividing by 2:
L = 7/2 y
Thus, two possible dimensions of the rectangle are 4x and 7/2 y.
