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,

Number one is 5
I think number two is 21

Answer:
x = 20
Step-by-step explanation:
The sum of the two angles is 90 degrees
x+3x+10 = 90
Combine like terms
4x+10 = 90
Subtract 10 from each side
4x+10-10 = 90-10
4x= 80
Divide each side by 4
4x/4 = 80/4
x = 20
ANSWER
The is 10 is meters
EXPLANATION
The area of a tra-pezoid can be calculated using the formula;

We substitute the values to get,




The height is 10 meters.
ratio of voljumes = 3^3 : 4^3 or 27:64
small/large = 27 / 64
vol of smaller = 27 * 320 / 64
=135
