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,
Answer:
= -27a^3+108a^2-144a+64
Step-by-step explanation:
Simplify:
=64-144a+108a^2-27a^3
=64+-144a+108a^2+-27a^3
Answer
= -27a^3+108a^2-144a+64
The multiplier for increasing by 7.25% is 1.0725. To get our answer we times the price by the multiplier to the power of the amount of years:
19,000 x 1.0725⁶ ( it's to the power of 6 because of the six years)
= 28,915.94
= $28,916 (to the nearest dollar)
So if the loan is to be paid in full the $28,916 (to the nearest dollar) must be paid back.
Ques 1: 1min->12 breathsl
24*60=1440->12*24*60=17280breaths
answer : 17280 breaths
ques 2: 2 weeks(6*2=12days) -> 2808
