Name the property used to make the conclusion. If x=3, then 5x=15.
bulgar [2K]
Note that both sides were multiplied by 5.

So that would be "Multiplication Property of Equality."

Basically, this property states that if a=b, then ac = bc.

A data set has a mean of 112 and a standard deviation of 2.5.
Ahat [919]

Answer with explanation:

Mean of the data set\mu = 112

Standard Deviation of the data set\sigma =2.5

Since , 50% of data lies on both side of the mean.

 Z at 50% = 0.1915

Margin of error for this data set

       =Z_{50 \text{percent}}\times\frac{\sigma}{\sqrt{\mu}}\\\\=0.1915 \times \frac{2.5}{\sqrt{112}}\\\\=0.1915 \times \frac{2.5}{10.58}\\\\=0.1915 \times 0.2362\\\\=0.0452    

Margin of error=0.045(approx)

Find the perimeter of a rectangle with a length of 6x+3 and a width of -2x-5.
blsea [12.9K]
The simple way of calculating a perimeter is to add all of the sides.
For a rectangle this would equal 2 x length + 2 x width
P = 2(6x + 3) + 2(-2x - 5)
= 12x + 6 - 4x - 10
= 8x - 4

At a higher level both the length and width must be greater than zero (= zero is a trivial rectangle)
6x + 3 > 0
6x > -3
x > -0.5

-2x - 5 > 0
2x + 5 < 0 (multiplying by -1 reverses the inequality)
2x < -5
x < -2.5

This rectangle cannot exist as x cannot be < -2.5 and > -0.5 at the same time!
