Given here are a set of sample data: 12.0, 18.3, 29.6, 14.3, and 27.8. the sample standard deviation for this data is equal to _
disa [49]
The answer is 7.9306

Using the formula in the attached:
Where: xi = sample value; μ = sample mean; n = sample size

1.) Calculate the mean first:
μ = 12.0 + 18.3 + 29.6 + 14.3 + 27.8 / 5
   = 102 / 5
μ = 20.4

2.) Using the mean, calculate (xi - μ)² for each value:
(12.0 - 20.4)² = 70.56
(18.3 - 20.4)² = 4.41
(29.6 - 20.4)² = 84.64
(14.3 - 20.4)² = 37.21
(27.8 - 20.4)² = 54.76

3.) Sum the squared differences and divide by n - 1.
μ = 70.56 + 4.41 + 84.64 + 37.21 + 54.76
   = 251.58 / 5-1
μ = 62.895 (this is now called sample variance)

4.) Get the square root of the sample variance:
 √62.895 = 7.9306

If Neil Works 3/4 of an hour on Monday and 6/10 of an hour on Tuesday how much time will she work altogether?
jek_recluse [69]

Answer:

C

Step-by-step explanation:

3/4 + 6/10

Find a common denominator and find what you multiply to each denominator to get that number and multiply the numerator by the same amount

(3/4 * 5/5) + (6/10 * 2/2)=

15/20 + 12/20

Then add

15/20 + 12/20= 27/20

Then finally convert to mixed number

27/20 = 1 7/20

Cone A is divided into Cone B and Frustum C. B A 12cm C 20cm 20cm Express the volume of Frustum C as a fraction of the volume of
zaharov [31]

The volume of the frustum is volume of the whole cone(A) minus the smaller cone(B) which is would give the volume of frustum(C) = 256cm³

<h3>Calculation of a frustum</h3>

The volume of cone A V=πr²h/3

Where radius = 20cm

The volume of cone B = V=πr²h/3

Where radius = 12cm

Therefore volume of frustum =

V=π * 20² * h/3 - π * 12² *h/3

The variables will cancel out each other

V = 20² - 12²

V = 400- 144

V = 256cm³

Therefore, the volume of the frustum(C) = 256cm³

Fill in the Blanks
tatyana61 [14]

Answer: This would fill 4 and 4/9 containers.

Explanation:

Since we have given that

Quantity of walnuts in a container is given by

6\frac{2}{3}=\frac{20}{3}\ pounds

Quantity of walnuts which divided equally into containers is given by

1\frac{1}{2}=\frac{3}{2}\ pounds

Now, number of containers they would fill is given by

\frac{\frac{20}{3}}{\frac{3}{2}}=\frac{20\times 2}{3\times 3}=\frac{40}{9}

When we change it into mixed fractions we get,

\frac{40}{9}=4\frac{4}{9}

So, blank will be filled with '4'.
