Listed below are the amounts​ (dollars) it costs for marriage proposal packages at different baseball stadiums. Find the​ range,
yulyashka [42]

Answer:

Range = 2460 dollars, Variance = 516414.6 dollars^2, Standard deviation = 718.6199 dollars . There are two outliers and they are likely to have much of an effect on the measures of variation.

Step-by-step explanation:

The smallest value in the sample data is min = 50 dollars and the largest value is max = 2500 dollars, therefore, the range is Range = max - min = 2500 - 40 = 2460 dollars. On the other hand, the formula to compute the sample variance is S^2 = \frac{1}{n-1}\sum_{i=1}^{n} (x_{i}-\bar{x})^2 where \bar{x} is the sample mean, n is the sample size and the x_{i} are the sample values. In this case the sample variance is s^2 = 516414.6 dollars^2, the sample standard deviation is defined as the squared root of the sample variance, so, the sample standard deviation is s = 718.6199 dollars. There are two outliers because 1750 dollars and 2500 dollars are very different compared to the other values, these two numbers are very large and they are likely to have much of an effect on the measures of variation because these measures are sensible to outliers, they are no robust measures.

8x-y=19, y+3x=7 Ax+By=c form
Dmitriy789 [7]

Answer:

8x-y=19 is already in your Ax+By=C form

For your second one you need to switch your x and y around so

3x+y=7 gives you your Ax+By=C form

Now you want to use the system of elimination to solve the system of equations

So when you take 8x-y=19 you then add 3x+y=7

8x+3x= 11x

-y+y=0 (crosses out... why it's called elimination)

19+7=26

Your equation is now 11x=26

You then divide both sides by 11 to get

x=26/11

(Hope this helps ya ;)
