Answer:
No

No, because s is less then 2. 7 is not less then 2.
‘Hope that helps! :)
The total amount of money (y) paid by Lauryn at the end of each month (x) is given by: y = 20x
Here, x is the independent variable which represent the number of months Lauryn has paid the money.
The dependent variable is y which represent the amount of money Lauryn has paid at the end of that month.
The required table is
x y
1 20
2 40
3 60
4 80
5 100
<span>ill try to help get u started
y = x^2 +1 ;
</span>The y values are 10,5,2,1,2,5,10
For y = x^2-1, they are
<span>8,3,0,-1,0,3,8</span>
Answer:
it is number 4 why because
Answer:
A. positive slope.
Step-by-step explanation:
In the least square linear regression of Y on X, the straight line of best fit is given by,
------------------(1)
[where is the estimated value of Y]
Clearly, here,
Slope pf the line = ---------------------------------(2)
Y- intercept = -----------------(3)
and,
X - intercept = ----------------(4) [putting in (1) and taking the value of X]
So,
since
[since or will result in a degenerate distribution, hence these cases are discarded]
so, correlation coefficient = > 0 implies
A. positive slope. [as evident from (1)]
clearly from (3) and (4) all the other options are false.
