Find the mean of the following 2x-5y,5x+2y,8x+6y,x-y

White raven [17]

Answer: 4x + 0.5y

Step-by-step explanation:

Concept:

Here, we need to understand the idea of the mean (average).

The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers.

If you are still confused, please refer to the attachment below for a graphical explanation.

Solve:

**Disclaimer** I assume the question is asking for the arithmetic mean instead of geometric. If it was, then you can refer to my answers. If it was not, then you can point it out and I will redo the question.

Terms: 2x-5y, 5x+2y, 8x+6y, x-y

Number of terms: 4

[(2x-5y) + (5x+2y) + (8x+6y) + (x-y)] / 4

=[2x + 5x + 8x + x + 2y - 5y + 6y - y] / 4

=[16x + 2y] / 4

=4x + 0.5y

Hope this helps!! :)

Please let me know if you have any questions

Ok this might be wrong but you don’t have much time so I will give my best

I’m pretty sure the of the x and y thing you do this you see the box with the number in it do this the top two says 2 and 4 the left side is x and the right side is y so you see at the bottom of the number Line thing on the right is a little x that where you start so the box of numbers the fist one says 2 so go to the bottom number line and there is the number two now the top right box with numbers says 4 so go up 4 squares from the number 2 and make a dot where they come together

The Wanting Recognition (WR) Scale provides a quantitative measure of a person's level of need for approval and sensitivity to s

levacccp [35]

Answer:

99% of the confidence level of the mean WR score for all convicted drug dealers

(37.4544, 40.5456)

Step-by-step explanation:

Step(i):-

Given that the sample size 'n' = 100

Given that the mean of the sample(x⁻) = 39

Given a standard deviation of the sample (σ) = 6

Level of significance = 0.01 or 99%

Step(ii):-

99% of the confidence level of the mean WR score for all convicted drug dealers

$(x^{-} - Z_{0.01} \frac{S.D}{\sqrt{n} } ,x^{-} + Z_{0.01} \frac{S.D}{\sqrt{n} })$

$(39 -2.576 \frac{6}{\sqrt{100} } ,39 + 2.576 \frac{6}{\sqrt{100} })$

(39 - 1.5456 , 39+1.5456)

(37.4544, 40.5456)

Final answer:-

99% of the confidence level of the mean WR score for all convicted drug dealers

(37.4544, 40.5456)
