If Owen and Eliza had a combined taxable income of $68,200 and filed their federal income tax return with the Married Filing Joi
tangare [24]

Answer:

9425

D

Step-by-step explanation:

They are in the third tax bracket down. That means that their joint income is over 67900 but less than 137050.

The base rate is 9350. But they are 68200 - 67900 = 300  over the minimum.

So 25% of that 300 is also to be paid to the government 25/100 * 300 = 75 dollars

Now they must pay 9350 + 75 = 9425

Answer D

The figure will be dilated by a scale factor of 1.2. Find the new length. W: 25 in L: 40 in​
Ghella [55]

The new length and width is 48in and 40in respectively

<h3>Dilation</h3>

Given the following information

  • Width = 25in
  • Length = 40in

If the length and the width are dilated by a factor of 1.2, the new length and width is expressed as;

W = 25(1.2) = 30in

L = 40(1.2)

L = 48 in

Hence the new length and width is 48in and 40in respectively

timofeeve [1]

Median is the central tendency of the data and always exists in the middle of the data set.

<h3>What is the median?</h3>

The Median is the middlemost value of the numbers arranged in the ascending orders. Median is the central tendency of the data and always exists in the middle of the data set.

The process of finding the median if the number of data points is even is as follows:

  • Put the numbers or the data points in the order(increasing or decreasing i.e. ascending or descending order)
  • Next cross of the high/ low pairs
  • Add the leftover numbers
  • and divide the number( as obtained in the above step by 2)

( if the number of data pints were even then we just need to arrange the numbers and cross the high/low pair and only one data point will be left which acts as the Median of the data set)
