Please help me understand how to evaluate the following in an easy explanation.

Please help me understand how to evaluate the following in an easy explanation.

Answers

Answer:

first you should divide 16 to 8 then there the answer will 2 but at 8 there is minus sign so , you should put there minus so, your answer will -2.

In second portion , first you should multiply 2 into 3 answer will 6 but you should remember that minus sign minus sign (- -) will addition sign so answer will be 6

Ok here is how I do it. 16 divided by 8 would be 2. One of the numbers out of the two are negative, meaning the answer will be negative. Put it this way. One negative times one positive equals a negative. One positive times a positive equals a positive, and one negative times one negative equals a positive. I won’t go too far into depth or I will confuse you. So just add negative to the your answer in the first one and you get -2.

For the second one, it is two negatives. Like I said earlier, if there are two negatives. You will get one positive. So then just multiply 2 and 3, and you get positive 6. There you are. Message or comment me if you need more help

Riko wants to find the distance between the points (2, 3) and (2, 5). His work is shown. The distance

Answers

Answer:

incorrect

Step-by-step explanation:

The calculation he has done only calculates the distance between the y- coordinates of the points.

Calculate the distance d using the distance formula.

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 2, - 3) and (x₂, y₂ ) = (2, - 5)

d = \(\sqrt{(2+2)^2+(-5+3)^2}\)

   = \(\sqrt{4^2+(-2)^2}\)

   = \(\sqrt{16+4}\)

   = \(\sqrt{20}\) = \(\sqrt{4(5)}\) = 2\(\sqrt{5}\) ← exact distance

Answer:Sample Response: No, Riko is not correct. The points do not have the same x-coordinates. If you connect the points, they do not form a horizontal or vertical line, so you cannot count spaces or use absolute value to find the distance.

8 to 12 is the same as 4 to 6;  cross-products are both equal to 48

2 to 4 is the NOT the same as 4 to 6;  cross-products are not equal, 12≠16

6 to 9 is the same as 4 to 6;  cross-products are both equal to 36

thank you​

Answers

Answer:

\(3 + 3^2 + 3^3 ...+ 3^n = \frac{3(3^n - 1)}{2}\)

Step-by-step explanation:

Given

\(3 + 3^2 + 3^3 ...+ 3^n\)

Required

Show that the sum of the series is \(\frac{3(3^{n}-1)}{2}\)

The above shows the sum of a geometric series and this will be calculated as shown below;

\(S_n = \frac{a(r^n - 1)}{r - 1}\)

Where

a = First term;

\(a = 3\)

r = common ratio

\(r = \frac{3^2}{3} = \frac{3^3}{3^2}\)

\(r = 3\)

Substitute 3 for r and 3 for a in the formula above;

\(S_n = \frac{a(r^n - 1)}{r - 1}\) becomes

\(S_n = \frac{3(3^n - 1)}{3 - 1}\)

\(S_n = \frac{3(3^n - 1)}{2}\)

Hence;

\(3 + 3^2 + 3^3 ...+ 3^n = \frac{3(3^n - 1)}{2}\)

Answer: Range and mean = 8 of both

variance of Set X= 4.7

variance of Set Y= 4.6

Step-by-step explanation:

Two sets of data, set X and set Y are given

a.) Range is the difference of the highest value and the lowest value,

Therefore, Range of set X = 12-4=8

Range of set Y = 12-4=8

Now, Mean of a given data set is the average of all the terms present in the given data set

Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8

Mean of set Y= (4+5+7+32+20+12)/10= 8

Therefore, both the data sets has same range and mean.

b.) Standard deviation tells about the variability of the date and is given by,

S.D= σ = √∑ ( X − μ )^2/n

S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7

S.D of set Y= √(16+9+1+0+4+16)/10= √4.6

Variance is the square of S.D, that is, σ^2

Therefore, variance of set X=4.6

variance of set Y= 4.7

c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.
