Answer:
do you expect me to flip sideways just to help you cheat on ur homework
Step-by-step explanation:
A. funtional
B. linear
C. radical
D. quadratic
I think the answer is D. Quadratic. It is common. I have heard it before and is more common than the other answers. Hope it is right!
Based on the calculations, Helen needs to buy 60 feet of fence panels for her rectangular garden in the backyard
From the question, we have the following parameters that can be used in our computation:
This means that
Perimeter = 20 yards
By metrric unit of conversion, we have
1 yard = 3 feet
So, we have
Perimeter = 20 * 3 feet
Evaluate
Perimeter = 60 feet
Hence, she needs to buy 60 feet of fence panels

(B) Approximately normal with mean $206,274 and standard deviation $37,881
(C) Approximately normal with mean $206,274 and standard deviation $520
(D) Strongly right-skewed with mean $206,274 and standard deviation $3,788
(E) Strongly right-skewed with mean $206,274 and standard deviation $37,881
Approximately normal with mean is $206,274 and standard deviation is $3,788 and this can be determined by applying the central limit theorem.
Given :
According to the central limit theorem the approximately normal mean is $206274.
Now, to determine the approximately normal standard deviation, use the below formula:
---- (1)
where 's' is the approximately normal standard deviation, 'n' is the sample size, and is the standard deviation.
Now, put the known values in the equation (1).
s = 3788.1
So, the correct option is A).

Answer:
(A) Approximately normal with mean $206,274 and standard deviation $3,788
Step-by-step explanation:
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.
Population:
Right skewed
Mean $206,274
Standard deviation $37,881.
Sample:
By the Central Limit Theorem, approximately normal.
Mean $206,274
Standard deviation
So the correct answer is:
(A) Approximately normal with mean $206,274 and standard deviation $3,788
Step-by-step explanation:
sec(90-A) . Sin A = cot (90-A) . tan(90-A)
cosec X sinA = tanA X cotA
1/sinA X sinA = tanA X 1/tanA
1=1
Hence proved
L.H.S=sec(90-A)·sinA
=cosecA·sinA ;[sec(90-A)= cosecA]
=1/sinA·sinA ;[cosecA=1/sinA]
=1
R.H.S=cot(90-A)·tan(90-A)
=tanA·cotA ;[cot(90-A)=tanA, tan(90-A)=cotA]
=tanA·1/tanA ;[cotA=1/tanA]
=1
thus, L.H.S=R.H.S
