The unsorted stem-and-leaf diagram would look like this:

5 | 6, 3, 5, 0, 2

3 | 2, 7, 3, 3, 4

2 | 6, 9, 1, 1

1 | 7, 1, 1, 6, 8

4 | 4, 2, 4, 3, 4

Basically, you separate the given set of numbers by their whole number part (the digit before the decimal) and list the numbers' fractional part (digit after the decimal) in the order you see them.

The sorted diagram would then be

1 | 1, 1, 6, 7, 8

2 | 1, 1, 6, 9

3 | 2, 3, 3, 4, 7

4 | 2, 3, 4, 4, 4

5 | 0, 2, 3, 5, 6

michelle invested $10000 in an account that earns 8.5% interest that is compounded monthly. Determine the amount of interest ear
Semmy [17]

Answer:

$25,626.53

Step-by-step explanation:

You are going to want to use the compound interest formula, which is shown below.

A=P(1+\frac{r}{n} )^{nt}

<em>P = initial balance</em>

<em>r = interest rate (decimal)</em>

<em>n = number of times compounded annually</em>

<em>t = time</em>

<em />

First, change 8.5% into a decimal:

8.5% -> \frac{8.5}{100} -> 0.085

Now lets plug in the values into the equation:

A=10,000(1+\frac{0.085}{12})^{12(15)}

A=35,626.53

Lastly, subtract the total from the initial balance:

35,626.53 - 10,000 = 25,626.53

Michelle earned $25,626.53 in interest.

In one statistics course, students reported studying an average (mean) of 9.92 hours a week, with a standard deviation of 4.54.
quester [9]

Answer:

For the student who is studying 10 hours a week is in the 57.93th percentile.

Step-by-step explanation:

Corresponding z-score for the student who studies 10 hours a week can be calculated by the formula

z=\frac{x-M}{s} where

  • x is the hours student work in a week, which is 10,
  • M is the mean studying hour of the class, which is 9.92,
  • s is the standart deviation which is 4.54

from here we find that z=\frac{10-9.92}{4.54}≈0.2

Corresponding percentile for z=0.2 is 57.93
