Answer: $142.58\text{squared kg}[$

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given : A random sample of 10 subjects have weights with a standard deviation of 11.9407 kg

i.e. $\sigma = 11.9407$

Since we know that the value of variance is the square of standard deviation.

i.e. $\text{Variance}=\sigma^2$

Therefore, to find the value of variance, we need to find the square of the given standard deviation.

i.e. $\text{Variance}=(11.9407)^2=142.58031649\approx142.58\text{squared kg}$

Thus, the variance of their weights = $142.58\text{squared kg}[$

The value of the solid's surface area is equal to the value of the solid's volume. find the value of x. 5*6*x

Answers

Given

a cuboid with length, width, height dimensions 5, 6, x

Find

the value of x that makes the numerical value of the total surface area equal to the numerical value of the volume

Solution

The volume is given by

... V = L·W·H = 5·6·x = 30x

The area is given by

... A = 2(L·W + H(L+W)) = 2(5·6 +x(5+6)) = 2(30 +11x) = 60 +22x

When these are equal, we have

... 30x = 60 +22x

... 8x = 60

... x = 7.5

The desired value of x is 7.5.

Answer:

59.44 units²

Step-by-step explanation:

The area of each triangular section can be computed from the side length (5 units) and the central angle (72°) as ...

... section area = (1/2)sin(72°)·5² ≈ 12.5·0.951057 ≈ 11.8882 . . . units²

Then 5 such sections will have an area of ...

... pentagon area = 5·11.8882 units² = 59.4410 units²
