Answer:
Approximately normal
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean
and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean
and standard deviation 
In this question:
As the sample size is above 30, even though the underlying distribution is right-skewed, the shape of the sampling distribution of the sample means will be approximately normal.
The amplitude of
is the absolute value of
. So first you need to condense the given function into one sine expression.
Recall that

so you need to choose
and
accordingly.
If we line up the terms of the given function with the expanded one above, we should have

Now, using the Pythagorean identity,

so the amplitude is √29.
Just for completeness, we also get

where
is any integer.
<u>Answer</u>
2(l+w)
<u>Explanation</u>
Rectangle is a fore sided figure of which two opposite sides are equal.
Let its longer side be l and its shorter side be w.
Perimeter is the distance all round.
perimeter = l + w + l + w
= l+l+w+w
= 2l + 2w
= 2(l + w)
Step 1: 22 times 3 is 66
Step 2: Bring down 1/8 divided by 66
When you do 1/8 divided by 66 you get 0.00189393939
So the 1/8 divided by 22*3 = 0.00189393939
Answer:
$2
Step-by-step explanation:
x = daylily
y = geranium
1x + 5y = 22
13x + 1y = 30
Multiply second equation by 5 and subtract the two equations.
1x + 5y = 22
- (65x + 5y = 150)
-64x = -128
x = 2
So one daylily costs 2 dollars
