Let

Timothy collected=3x-17

ATQ

$\\ \tt\hookrightarrow x+3x-17=527$

$\\ \tt\hookrightarrow 4x-17=527$

$\\ \tt\hookrightarrow 4x=544$

Charity=136

What is the best way to classify each equation?

MrRa [10]

<span>5x-20=2(3x-10)=6x-20, eqivalent to 5x-20=6x-20, it s a contradicion; a 2. 4x - 16 - 2x = 2(x - 8), for this 4x - 16 - 2x =4x-2x-16=2x-16, and 2(x-8)=2x-16, so 4x - 16 - 2x = 2(x - 8) is a identity 3. For the case of 6x - 15 = 3(2x - 6)=6x-16, we have 6x - 15 = 6x-16 it is contradiction 4. 5x - 3(x - 4) = 2(x - 6), we know that 5x - 3(x - 4) =5x -3x+12=2x+12, and 2(x-6)=2x-12, so we have 2x+12=2x-12. That is also a cotradiction, finally we have 1.B, 2.A, 3.B, 4.B</span>

Sixteen college freshmen were asked to record the number of alcoholic drinks they typically consume in a week. Here are their da

rjkz [21]

Solution: The correct option is d. 8.75

<u>Explanation:</u>

The formula for variance is:

$Variance =\frac{\sum(x-\bar{x})^{2}}{n}$

First we need to find the mean $\bar{x}$ of the given data:

$\bar{x}=\frac{2+4+6+0+1+10+9+0+6+3+6+8+5+4+6+2}{16}=\frac{72}{16} =4.5$

Now let's find $\sum(x-\bar{x})^{2}$ , please have a look at the attached picture:

$\therefore Variance = \frac{140}{16}=8.75$

The area of a circle is less than 1 dm². Find the radius of the circle. The area of a circle is less than 1 dm². Find the rad

Ipatiy [6.2K]

$\bf \textit{area of a circle}\\\\
A=\pi r^2\qquad 
\begin{cases}
\textit{let's say the Area is 1 exactly}\\
A=1
\end{cases}\implies 1=\pi r^2
\\\\\\
\cfrac{1}{\sqrt{\pi }}=r$

if you drop the radius to less than that, then the Area will also drop to less than 1 unit, in this case it happens to be a decimeter

Find the area of the triangle below.

lapo4ka [179]

35 cm
using the formula a=1/2(b)(h), we can plug in 14 for b and 5 for h. This gives us 70, and when we multiply by 1/2 it leaves 35 cm.
