The mean is  6394530.35 and the median is = 3355572.5

The missing data is attached in the answer.

<h3>What is Mean ?</h3>

Mean is the average value of the data points , it is determined by dividing the total sum of the data points to the number of data points.

Mean and Median is the measure of the central; tendency of the data.

Mean is given by

Sum of the observations/number of observations

= (741894 + 6931071....)/20

= 6394530.35

2) To find median

The data needs to be arranged in ascending order

Then the median is the middle number of the arranged data

Here the median is = 3355572.5

Determine whether the sequence converges or diverges. If it converges, find the limit. (If an answer does not exist, enter DNE.)
In-s [12.5K]

Answer:

The sequence diverges.

Step-by-step explanation:

A sequence a_{n} converges when \lim_{n \rightarrow \infty} a_{n} is a real number.

In this question, the sequence given is:

a_{n} = 4n\cos{(7n\pi)}

The cosine is always going to be between -1 and 1, so for the convergence of the sequence, we look it as: a_{n} = 4n. So

\lim_{n \rightarrow \infty} a_{n} = \lim_{n \rightarrow \infty} 4n = \infty

Since the limit is not a real number, the sequence diverges.

Where would you insert parentheses to make the statement true?
9966 [12]
Just around the 15 and 3. So it would be

(15-3)x4+9=57

This is because (15-3)= 12
12x4=48
48+9= 57

If I varies inversely with R and I = 0.25 when R = 18, which equation should be used to show this relationship?
pashok25 [27]
Inverse relationships are of the form xy=k or if you prefer  y=k/x so to find the constant we can say:

18(0.25)=k=4.5

So you could say: IR=4.5 or I=4.5/R

Prove that 3 power p + 1 - 3 power P upon 2 multiply 3 power p is equal to 1 ​
Anit [1.1K]

Answer:

see explanation

Step-by-step explanation:

note that 3^{p+1} = 3^{p} × 3 ( when multiplying exponents are added )

Given

\frac{3^{p+1}-3^{p}  }{2.3^{p} } ← factor out 3^{p} on numerator

= \frac{3^{p}(3-1) }{2.3^{p} }

= \frac{2.3^{p} }{2.3^{p} }

= 1

4+7x=-24 how do you solve this algebraic expression
Lady_Fox [76]

Answer:

In order to solve this algebraic expression, you need to get the variable x by itself

Step 1: subtract 4 from each side

4-4+7x=-24-4 (4-4=0, those cancel out) (-24-4=-28)

7x=-28

Step 2: divide both sides by 7

7x/7=-28/7 (7x/7=x) -28/7=-4)

Your final answer would be x=-4

Hope this helps ;)
