Exponential form is when a certain number is raised to the power of a certain number or also known as exponents. Exponents signifies that the base or the number that is being raised to a certain powers will be multiplied a number of times, based on the exponents).
Exponential form is defined as repeated multiplication of the base.
Answer:
3. The amount of wallpaper for a wall in a bedroom
Step-by-step explanation:
1. The number of towels I can fit in a bathroom cabinet
<em>No, sounds more like volume, since a cabinet has space inside.</em>
2. The amount of ribbon used to decorate from one end of a room to the another
<em>No, sounds like perimeter, since a ribbon would need to cover space in one direction.
</em>3. The amount of wallpaper for a wall in a bedroom
<em>Yes, wallpaper is applied in 2 directions and lays flat on a surface to cover a certain area.</em>
Answer:
(a) 1/3
(b) 1/15
Step-by-step explanation:
(a)Let X denote the waiting time in minutes. It is given that X follows a uniform distribution, and since the variable being measured is time, we assume it to be a continuous uniform distribution.
![\[f_X(x) =\begin{cases} \frac{1}{30} & 0\leqx\leq 30\\ 0 & otherwise \end{cases}\]](https://tex.z-dn.net/?f=%20%5C%5Bf_X%28x%29%20%3D%5Cbegin%7Bcases%7D%20%5Cfrac%7B1%7D%7B30%7D%20%26%200%5Cleqx%5Cleq%2030%5C%5C%200%20%26%20otherwise%20%5Cend%7Bcases%7D%5C%5D)
Now
.
Jack or Rose arriving first is equally likely, therefore the probability of Jack waiting is just the half of the above obtained probability i.e 
(b)Using the formula for the expectation of a uniform continuous distribution,
Multiply the numbers and add the exponents.
(2*3)(x^(5+3/5))
= 6x^(28/5)
