What you have to do is divide. Divide 720 - 60 = 12. So there are 12
Answer:
A=2m⁴+17m³+11m²+24m
Step-by-step explanation:
The area of rectangle is length × width
A=LW
A=(m+8)(2m³+m²+3m)
A= 2m⁴+m³+3m²+16m³+8m²+24m
A=2m⁴+m³+16m³+3m²+8m²+24m
A=2m⁴+17m³+11m²+24m
Assuming this a system of equations and you need the solution set, you can solve it by elimination or substitution--whichever you find easier. i'll use elimination:
2x - 5y = 3
x - 3y = 1
here, it'll be pretty easy to get your x values to match so you can cancel them out. just multiply your bottom equation by 2, then subtract:
2x - 5y = 3
- (2x - 6y = 2)
your 2x's cancel out and -5y + 6y is simply y, so you're left with:
y = 1
that already gives you your answer, because you can see that the first ordered pair is the only pair with a y-value that's 1, but still, to check your x-value, you just plug your y-value into one of the equations:
x - 3(1) = 1
x - 3 = 1
x = 4
so your solution is (4, 1).
Answer: although the question is incomplete, but from the details i got online, am able to give this answer.
A linear model is suitable. The regression relationship is thus ˆ
y= 0.511 + 0.159x where y = ridership and x = tourist numbers. Expected ridership if 10 million tourists visit is 2,101,000.The predicted ridership if there are no tourist at all is 511,000 though this prediction is out of sample and must be treated with caution as zero tourists is out of the data range used to form the model. The correlation coefficient is given by r=n∑XY-∑X∑Y/√[n∑X^2-(∑X)^2] [n∑Y^2-(∑Y)^2]
which equals 0.917 in this case. The R^2 = r^2 = 0.84.
