1 answer:
shusha [124]2 years ago
6 0

Step-by-step explanation:

(22 + (-6/20) × (214 - 10 ( -6/20)) - (284.75)

(22 - 6/20) × (214 + 60/20) - (284.75)

(22 - 0.3) × (214 + 3) - (284.75)

(21.7 × 217) - 284.75

4708.9 - 284.75

= 4424.15

Simplify the expression. (x1/6 y1/9)3
harina [27]
Ok, first let's multiply:
3 x 1/6 = 3/6 (simplify:) 1/2

Then multiply again:
3 x 1/9 = 3/9 (simplify:) 1/3

Now the expression is simplified to (1/2x, 1/2y)

Hope this helped! Please comment or DM me if you have anymore questions or don't understand :)

A statistic is said to be unbiased if
xxMikexx [17]

Answer:

A statistic is said to be unbiased if the mean of its sampling distribution is equal to the true value of the parameter being estimated.

Step-by-step explanation:

A parameter is a number that describes the population.  

A statistic is a number that describes a sample.  

A statistic used to estimate a parameter is unbiased if the mean of its sampling distribution is exactly equal to the true value of the parameter being estimated. For example, the mean of a sample is an unbiased estimate of the mean of the population from which the sample was drawn.

A statistic is biased if its expected value is not equal to the parameter.

A+b=95<br> 4a+1.50b=267.5
Papessa [141]

9514 1404 393

Answer:

  • a=50
  • b=45

Step-by-step explanation:

We can subtract the second equation from 4 times the first:

  4(a +b) -(4a +1.5b) = 4(95) -(267.5)

  2.5b = 112.5 . . . . . simplify

  b = 45 . . . . . . . . . . divide by 2.5

  a = 95 -b = 50 . . . find 'a'

The solution is (a, b) = (50, 45).
