Answer:
Step-by-step explanation:
The equation for the least-squares regression is,
where b is the slope and a is the intercept.
They can be found out by,
where,
r = correlation coefficient = 0.84
= standard deviation of y = 44,910
= standard deviation of x = 28,803
= mean of y = 774,140
= mean of x = 354,718
Putting the values,
Therefore the equation is,
Y<1/2x+1 is true..............................
Y-3=-2(x-5)
y-3=-2x+10
y=-2x+13
hope this helps :)
Answer: B
Step-by-step explanation:
Multiply 4 x 8 which is 32.
Then divide it by 1/2.
The answer is 16.
4 and a half to fill
30 in total minus the ones already used 30 - 18 = 12
A forth of the pages she wants to save which is about 7.5 of the total
12 - 7.5
Means she only has 4.5 pages left to use before she starts using her extra vacation pages
