Answer:

A sample of the data for the for the total income are as follows;

State, Indiana

Income, Number of families

0, 1

5, 1

10, 1

15, 1

20, 3

25. 4

From the data, we have;

The total income for the families from Indiana = $2,260

The total income for the families from New Jersey = $2,565

The average income for the families from Indiana ≈ $64.57

The average income for the families from New Jersey ≈ $73.29

The median income for the families from Indiana = 0

The median income for the families from New Jersey = $55

The first quartile for the families from Indiana = $0

The first quartile for the families from New Jersey = $0

The third quartile for the families from Indiana = $85

The third quartile for the families from New Jersey = $120

Samuel orders four DVDs from an online music store. Each DVD costs $9.96. He has a 25% discount code, and sales tax is 7.75%. Ro

Mumz [18]

Samuel's order will ultimately cost $39.84.

One DVD Samuel purchased cost $9.96.

He purchased four DVDs in total.

as a result, his total outlay will be 4 * 9.96 = $39.84.

The 7.75% sales tax that must be paid is disclosed to us.

Adding 7.75% to $39.84 yields

39.84 x 7.75/(100) (100)

= $3.0876

Consequently, the total amount of tax due is $3.0876.

Using 25% of 39.84 to calculate a 25% discount,

39.84 x 25/100

= 996/100

=$9.96

Consequently, the total discount on the total of $39.84 will be $9.96.

as a result, the updated purchase price will be,

39.84-9.96

=$29.88

adding the tax to the updated price,

9.96+29.88

= $39.84

Consequently, Samuel's order will ultimately cost $39.84.

<h3>How are percentages calculated?</h3>

One must compute percentage in order to determine the proportion of a whole that is stated in terms of 100. A percentage can be determined using one of two methods:

using the unitary method.

by changing the fraction's denominator to 100.

It should be noted that the second method of percentage computation is not used when the denominator is not a factor of 100. In these circumstances, we make use of the unitary approach.

tankabanditka [31]

Answer:

Step-by-step explanation:

<em>Degrees of freedom</em> is the number of values in the final calculation of a statistic that are free to vary. Degrees of freedom are related to sample size and calculated by n-1 where n is the <em>sample size</em>.

The Supervisor selects 10 teddy bears as sample from 5000 teddy bears produced daily. Therefore in this situation, there are 10-1=9 degrees of freedom

Give the equation of a line that is perpendicular to the line y= -4/5x+8

amm1812

Answer:

y = 5/4x

Step-by-step explanation:

The given line is written in slope-intercept form. In this form, the slope is the coefficient of x, -4/5.

The perpendicular line will have a slope that is the opposite reciprocal of this value:

-1/(-4/5) = 5/4

The simplest such line is the one that goes through the origin:

y = 5/4x
