Percentage

A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.

Algebraic Expressions

In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.

Numbers

Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.

Subtraction

Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.

please help with abc

Suppose that the amount of time that students spend studying in the library in one sitting is normally distributed with mean 46 minutes and standard deviation 23 minutes. A researcher observed 17 students who entered the library to study. Round all answers to 4 decimal places where possible.

a. What is the distribution of $ X $? $ X \sim N(46, 23) $

b. What is the distribution of $ \bar{x} $? $ \bar{x} \sim N(46, \frac{23}{\sqrt{17}}) $

c. What is the distribution of $ \sum x $? $ \sum x \sim N(46 \times 17, 23 \times \sqrt{17}) $

d. If one randomly selected student is timed, find the probability that this student’s time will be between 47 and 54 minutes.

e. For the 17 students, find the probability that their average time studying is between 47 and 54 minutes.

f. Find the probability that the randomly selected 17 students will have a total study time more than 816 minutes.

g. For part e) and f), is the assumption of normal necessary?
- ☐ No
- ☐ Yes

h. The top 10% of the total study time for groups of 17 students will be given a sticker that says "Great dedication". What is the least total time that a group can study and still receive a sticker?
