If the volume of a box is 1/8 cm^2 what are the lengths of its sides

mrs_skeptik [129]

Answer:

(1/2) cm = x

Step-by-step explanation:

This box has the shape of a cube. The formula for the volume of a cube is V = x^3, where x is the length of any one side of the cube.

Here the volume is (1/8) cm^3. We set this equal to x^3 and solve for x:

Taking the cube root of both sides, we get:

(1/2) cm = x

An insurance company study shows that 9% of U. S. adults have diabetes. Suppose 8 US adults are selected at random. LetX be the

Bogdan [553]

Using the binomial distribution, it is found that:

The mean of X is of 0.72.

The standard deviation of X is of 0.81.

<h3>What is the binomial probability distribution?</h3>

It is the probability of exactly <u>x successes on n repeated trials, with p probability </u>of a success on each trial.

The expected value of the binomial distribution is:

E(X) = np

The standard deviation of the binomial distribution is:

$\sqrt{V(X)} = \sqrt{np(1-p)}$

For this problem, the parameters are given as follows:

n = 8, p = 0.09.

Hence the mean and the standard deviation are, respectively:

E(X) = np = 8 x 0.09 = 0.72.

$\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{8 \times 0.09 \times 0.91} = 0.81$

Find the measures of the angles formed by (a) two consecutive radii and (b) a radius and a side of the given regular polygon.14.

Bezzdna [24]

Answer:

Step-by-step explanation:

Let radius = r and side of a regular polygon = s

a) The consecutive radii = r + r + 1

i) For Square ( 4- sides) : r + r + 1 = 90°

2r + 1 = 90°

ii) For Pentagon (5- sides) : 2r + 1 =108°

iii) For Hexagon (6- sides): 2r + 1 = 120°

iv) For Heptagon (7- sides): 2r + 1 = 129°

v) For Octagon (8- sides): 2r + 1 = 135°

vi) For Nonagon (9- sides): 2r + 1 = 140°

vii) For 20 sides: 2r + 1 = 162°

b) A radius and a side = r + s

i) For Square (4- sides): r + s = 90°

ii ) For Pentagon (5- sides): r + s = 108°

iii) For Hexagon (6- sides): r + s = 120°

iv) For Heptagon (7- sides): r + s = 129°

v) For Octagon (8- sides): r + s = 135°

vi) For Nonagon (9- sides): r + s = 140°

vii) For 20 sides: r + s = 162°

What is the average rate of change of the function over the interval x = 0 to x = 8?

notsponge [240]

To find the average rate of change, use the following formula:

$\frac{f(b) - f(a)}{b-a}$

a and b represent the values of the interval:

$a = 0, b = 8$

Simplify the original equation by combining like terms:

$2x - 13x = -11x$
$f(x) = -11x + 5$

Plug the interval values into the f(x) equation:

$f(0) = -11(0) + 5 = 0 + 5 = 5$
$f(8) = -11(8) + 5 = -88 + 5 = -83$

Plug in these values into the average rate of change formula:

$\frac{-83 - 5}{8 - 0} = \frac{-88}{8} = -11$

The average rate of change over this interval is -11.
