Answer:

Step-by-step explanation:
We are given the integral of:

First, we can use a property to separate a constant out of integrand:

Next, expand the expression (integrand):

Since
then it can be simplified to:

Recall the formula:

For
, we need to convert to another identity since the integrand does not have a default or specific integration formula. We know that:

We can solve for
which is:

Therefore, we can write new integral as:

Evaluate each integral, applying the integration formula:

Then add all these boxed integrated together then we'll get:

Expand 4 in the expression:

Therefore, the answer is:

Answer:
131.2 ;
12.8 ;
(118.4, 144)
Step-by-step explanation:
Given :
X = 131.2, s=55 , and n= 50
Point estimate of the mean :
Since, sample size is large (n > 30) ; the sample mean = population mean according to the center limit theorem :
Margin of Error = Zcritical * s / sqrt(n)
Zcritical at 90% = 1.645
Margin of Error : 1.645 * (55 / sqrt(50))
Margin of Error : 1.645 * 7.7781745
Margin of Error = 12.795097
Margin of Error = 12.8
The confidence interval (C.I) :
C.I = x ± margin of error
C. I = 131.2 ± 12.8
(131.2 - 12.8) ; (131.2 + 12.8)
(118.4, 144)
6
The 6 is the constant because it is never going to change
f(x), and others that contain x will change based on the value x
Since 6 doesn’t have the c with it it will be constant
Answer:
26.9
Step-by-step explanation:
Right now we have '8' in the tenths place. That '6' following the '8' requires us to round up. Thus, 26.86 to the nearest tenth is 26.9.
