Answer:
Total number of seats on plane is 150 seats.
Step-by-step explanation:
Number of seats on left side = 2 in each row
Number of seats on right side = 3 in each row
Total number of seats on right side = 90
Number of rows = total number of seats on right side/ number of seats on right in each row
Number of rows = 90 / 3 = 30 rows
So, total number of seats on left side = 30 * 2 = 60 seats
Total number of seats = total seats on right side + total seats on left side
Total number of seat = 90+ 60 = 150 seats
Hence total number of seats on plane is 150 seats.

Answer:
The second alternative is correct
Step-by-step explanation:
We have been given the expression;
The above expression can be re-written as;
On the other hand;
![y^{\frac{1}{3}}=\sqrt[3]{y}](https://tex.z-dn.net/?f=y%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%3D%5Csqrt%5B3%5D%7By%7D)
Therefore, we have;
![x^{9}\sqrt[3]{y}](https://tex.z-dn.net/?f=x%5E%7B9%7D%5Csqrt%5B3%5D%7By%7D)
Answer:
y = 1.5x + 3.2009
Step-by-step explanation:
I plotted your points and drew a linear regression line.
Its equation is
y = 1.5x + 3.2009
The regression line ignores the fact that the points fall along a smooth curve.
A parabolic regression line fits the data much better.
The equation for that line is
y = - 0.1647x² + 4.1357x - 5.6946
It is the equation for a vertical parabola opening downward.
