Answer:

  a) b = (1/2)/(2/3); b = 3/4

  b) it takes 3/4 bucket to fill a barrel

Step-by-step explanation:

a) Apparently, the number of buckets and the number of barrels is proportional, so we can write an equation for b, the number of buckets to fill a barrel, as ...

  buckets/barrels = b/1 = (1/2)/(2/3) . . . . the equation

Of course, b/1 = b, so we simply need to simplify the compound fraction to find the solution.

  b = (3/6)/(4/6)

  b = 3/4 . . . . the solution to the equation

__

b) The solution to the equation is the answer to the question. It takes 3/4 bucket of nuts to fill the barrel.

The formula for the standard deviation of a sample is:
timofeeve [1]

Answer:

d. The variance is 9.56 and the standard deviation is 3.09.

Step-by-step explanation:

From the above question, we are given the following data set.

3, 7, 8, 8, 8, 9, 10, 10, 13, 14

a) Mean = 3 + 7 + 8 + 8 + 8 + 9 + 10 + 10 + 13 + 14/ 10

= 90/10

= 9

b) Variance

The formula for sample Variance = (Mean - x)²/ n - 1

Mean = 9

n = 10

Sample Variance =

(3 - 9)² + (7 - 9)² + (8 - 9)² + (8 - 9)² + (8 - 9)² + (9 - 9)² + (10 - 9)² + (10 - 9)² + (13 - 9)² + (14 - 9)² / 10 - 1

= 36 + 4 + 1 + 1 + 1 + 0 + 1 + 1 + 16 + 25/9

= 86/9

= 9.555555556

≈ Approximately 9.56

Variance = 9.56

Sample Standard deviation = √Sample Variance

= √9.56

= 3.0919249667

≈ Approximately 3.09

Answer this for me pls
Alex73 [517]

Answer:

Slope = 2

Step-by-step explanation:

Find the slope by using the slope equation:

\frac{y^2 - y^1}{x^2 - x^1}

Plug in the numbers to the slope equation:

\frac{8 - (-8)}{2 - (-6)}

Which is equal to:

\frac{16}{8}

Which is simplified to:

2.

Mean:

(12+14+5+13+11)/5

11

Sum of squares:

12²+14²+5²+13²+11²

655

Variance = 655/5 - 11²

= 10

sd = sqrt(10)
