Answer:

c. The expected values of R and S will be equal, and the variability of R will be greater than the variability of S.

Step-by-step explanation:

This is Central Limit Theorem concept in which independent variables are added and form a normal distribution. The random sample of n sample size is selected which calculates normally distributed mean and variance. The expected value of samples distributor will be higher than the sample distribution.

Find the missing values in the following figures​
jekas [21]

Answer:

15.

  x = 40/9 = 4 4/9

  z = 24/5 = 4 4/5

17.

  x = 50

  y ≈ 11.5

Step-by-step explanation:

15. Corresponding segments are proportional:

  top right side / whole right side = x / 8

  5/(5+4) = x/8

  x = 8(5/9) = 40/9

  x = 4 4/9

__

  right side bottom / right side top = z / 6

  z = 6(4/5) = 24/5

  z = 4 4/5

____

17. The acute angles are complementary:

  x = 90 -40 = 50

__

From the Pythagorean theorem:

  y = √(15² -9.6²) = √132.84

  y ≈ 11.5

Is the product of 12 and 3/4 more or less than 12? Please explain answer
denis23 [38]
Hello!!

So the product is when numbers or variables are multiplied together. So if we have 12 * 3/4 then that equals 12/1*3/4=(12*3)/4=36/4=9

So we can see that the product of 12*3/4 is less than 12. We can see this right from the start by noticing that to be at least 12, then 12 would have to be multiplied by at minimum 1 meaning 12*1=12 anything less than 1 would result in a lesser value than 12.

Hope this helps!! Any questions please just ask!! Thank you!!!
