The other two sides might have the same length. Eg both the sides could be 8 inches. I think it’s this :)

padilas [110]

If you would like to write the equation in the above form, you can calculate this using the following steps:

x^2 - 8x + 13 = 0
(x - 4)^2 = x^2 - 8x + 16
(x - 4)^2 - 3 = 0
(x - 4<span>)^2 = 3
</span>
The correct result would be (x - 4<span>)^2 = 3.</span>

an item that was selling for $72 is reduced to $60 find the percent decrease in price round your answer to the nearest tenth of

lyudmila [28]

The amount of decrease is $12.00 :$72.00 - $60.00 = $12.00

you then divide the amount of decrease by the original price to find the percent decrease:

$12.00 ÷ $72.00 = .166666... = 16.7%

Answer:

About 3.11

Step-by-step explanation:

Add the numbers and divide the value by the number of values in the data set.

6 + 3 + 5 + 2 + 2 + 3 + 3 + 1 + 3 = 28

28/9 = 3.1111...

3.111... ≈ 3.11

Determine the margin of error, m , of a 99% confidence interval for the mean IQ score of all students with the disorder. Assume

madreJ [45]

Answer:

E= 6.45

standard deviation is σ = 15,

The critical value is z(α/2) = 2.58.

Step-by-step explanation:

Margin error is the value that is lie above and below the sample.It gives percentage of numbers.Its is the product of critical value standard deviation and standard error of statistic.

General formula for the margin of error is

Margin of error = critical value × standard error of statistic

= $z \alpha /2$ × σ √n

z-value from two tailed is listed below:

From the table of standard normal distribution, probability value of 0.10.

row and column values gives the area to the two tail of z.

The positive z value is 2.58.

standard deviation is σ = 15,

The critical value is z(α/2) = 2.58.

after putting these vales we obtain the margin of error value that is

E= 6.45
