21. Jesse saved his allowance all summer to by a wake board. He put $36.50 in his piggy bank every two weeks for 3 months. He sp
ddd [48]

So lets start out this problem with the initial amount of money jesse has:

$36.50 x (2 (times a month)) x (3 months) = $219

Then, you take 1/4 of his money (which can be converted to the decimal 0.25) and you subtract it from $219

$219 - ($219 x 0.25)

$219 - $54.75 = $164.25

Next, you have to subtract Jesse's lunch ($14.25) from the money he has left after purchasing his tow rope and bathing suit.

$164.25 - $14.25 = $150

Jesse's wake board cost him $150.

Find and interpret the mean absolute deviation of the data. Round your answers to the nearest tenth. If necessary 101.5 98.7 95.
lesya692 [45]

Answer:

\bar X = 100.4

And we can calculate the deviations from each value like this:

|101.5-100.4 |=1.1

|98.7-100.4 |=1.7

|95.4-100.4 |=5.0

|92.3-100.4 |=8.1

|109.8-100.4 |=9.4

|104.7-100.4|=4.3

And the mean absolute deviation would be:

MAD =\frac{1.1+1.7+5.0+8.1+9.4+4.3}{6}= 4.93

Step-by-step explanation:

For this case we have the following dataset given:

101.5 98.7 95.4 92.3 109.8 104.7

We can calculate the mean with the following formula:

\bar X =\frac{\sum_{i=1}^n X_i}{n}

And replacing we got:

\bar X = 100.4

And we can calculate the deviations from each value like this:

|101.5-100.4 |=1.1

|98.7-100.4 |=1.7

|95.4-100.4 |=5.0

|92.3-100.4 |=8.1

|109.8-100.4 |=9.4

|104.7-100.4|=4.3

And the mean absolute deviation would be:

MAD =\frac{1.1+1.7+5.0+8.1+9.4+4.3}{6}= 4.93

An employer provides two payment options for employees. Option A: Receive $200 the first week. Receive an additional $50 for eac
elena-14-01-66 [18.8K]

Based on the information, it can be inferred that payment option A means a payment of $450, while option B means a payment of $300.

<h3>How much money does each payment option receive?</h3>

The payment options contemplated by the employer are distributed as follows:

Option A

  • First week: $200
  • Second week: $200 + $50 = $250
  • Third week: $250 + $50 = $300
  • Fourth week: $300 + $50 = $350
  • Fifth week: $350 + $50 = $400
  • Sixth week: $400 + $50 = $450

Option B

  • First week: $200
  • Second week: $220
  • Third week: $240
  • Fourth week: $260
  • Fifth week: $280
  • Sixth week: $300

Note: This question is incomplete because there is some information missing. Here is the missing information:

Complete the tables to show how much money would be received for both payment options, each week, for 6 weeks.
