Answer:

The relationship between the volume of a cylinder and its radius. To see that as the radius changes, the volume changes in proportion. Be able to comfortably use the volume of a cylinder formula. π is a constant and height, h, is a constant in this task.

Mr. Rr the Rreliable Rrobot has been programmed to whistle every 18 seconds and do a jumping jack every 42 seconds, starting fro
mixer [17]
15 mins = 900 s

We need to find all common multiples of 18 and 42 less than or equal 900.
We'll find the least common multiple first.

18|2
9|3
3|3
1

42|2
21|3
7|7

\text{lcm}(18,42)=2\cdot3^2\cdot7=126

Now, we nned to find all multiples of 126 that are less than or equal 900.
Those are 126,252,378,504,630,756,882. There are 7 of those.
Therefore the answer is 7.

Given the probability density function f(x) = 1/5 over the interval [4, 9], find the expected value, the
SIZIF [17.4K]

Answer:

Step-by-step explanation:

Assume that f(x) = 0 for x outside the interval [4,9]. We will use the following

E[X^k] = \int_{4}^{9}x^k f(x) dx

Var(X) = E[X^2}- (E[X])^2

Standard deviation = \sqrt[]{Var(X)}

Mean = E[X]

Then,

E[X] = \int_{4}^{9}\frac{1}{5}dx = \frac{9^2-4^2}{2\cdot 5} = \frac{13}{2}

E[X^2] = \int_{4}^{9}\frac{x^2}{5}dx = \frac{9^3-4^3}{3\cdot 5} = \frac{133}{3}

Then, Var(x) = \frac{133}{3}-(\frac{13}{2})^2 = \frac{25}{12}

Then the standard deviation is \frac{5}{2\sqrt[]{3}}
