Answer:
x=12 but who knows maybe
Step-by-step explanation:
if we are trying to say those lines are equal length than surely the equations must be equal value otherwise they aren't equal so we can probably set them equal to each other and solve for x right? 2x+6=3x-6 subtract 6. 2x=3x-12. subtract 3x. -1x=-12. divide by -1 so x=12.
The answer would be 6 bins.
Explanation:
Julio has a total of 48 comic books and he is able to fit 8 in one bin.
Therefore 48 divided by 8 is 6. Also 8 x 6 = 48
Answer:
x/10=-30/100 : -3
5/35 = 1/a : 7
2/x = 100/15 : .3
12/k = 4/1 : 3
2/8 = g/4 : 1
Step-by-step explanation:
Answer:
<u>670 numbers</u>
Step-by-step explanation:
T1=1*3-2
T2=2*3-2
T3=3*3-2
...............
<u>Tn=n*3-2</u>
n*3-2=2008
n*3=2010
n=2010:3
n=670 (numbers)
The regression equation for the data given is y= -8.57 -2.31x
Step-by-step explanation:
The first step is to form a table as shown below;
x y xy x² y²
1 4 4 1 16
2 1 2 4 1
3 5 15 9 25
4 10 40 16 100
5 16 80 25 256
6 19 114 36 361
7 15 105 49 225
28 60 360 140 984 ------sum
A linear regression equation is in the form of y=A+Bx
where ;
x=independent variable
y=dependent variable
n=sample size/number of data points
A and B are constants that describe the y-intercept and the slope of the line
Calculating the constants;
A=(∑y)(∑x²) - (∑x)(∑xy) / n(∑x²) - (∑x)²
A=(60)(140) - (28)(360) / 7(140)-(28)²
A=8400 - 10080 /980-784
A= -1680/196
A= - 8.57
B= n(∑xy) - (∑x) (∑y) / n(∑x²) - (∑x)²
B= 7(360)-(28)(60) / 7(60) - (28)²
B=2520 - 1680 /420-784
B=840/-364
B= -2.31
y=A+Bx
y= -8.57 -2.31x
