Answer:
The first thing we need to do is to find the area bounded by:
y = x^3
y = 0
between:
x = 0 and x = 2
This is the integral of the given function between x = 0 and x = 2, written as:
This means that the area of the bounded region is 4 square units.
Now, if we do a full rotation around the x-axis, the volume generated will be equal to the area that we obtained times 2*pi units.
The volume is:
V = (4 square units)*(2*pi units) = 8*pi cubic units.
(Notice that no option coincides with this, there may be a mistake in the options)

Hello!
The Confidence intervals for the population mean to follow the structure "point estimation"±" margin of error"
You as the store owner took a sample to determine the average amount of money a typical customer spends on your shop.
n= 26 customers.
X[bar]= $77.506
S= $11.0714
Assuming the variable X: the amount of money spent by a typical customer has a normal distribution and that there is no information about the population standard deviation, the best statistic to use for this estimation is a Students-t:
[X[bar] ± *
]
The margin of error of the interval is:
d= *
d= 6.051
I hope it helps!
