A weather historian gathered data about the average temperature and total snowfall in her city during the month of January in re

Xelga [282]

Option A

The inches of snow fall during the month of January when the average temperature is 2°F is 17.747 inches

Solution:

Given that the equation of the line of best fit is:

y = -0.368x + 18.483

Where "y" is the total snowfall in her city

"x" is the average temperature

To find: Inches of snow fall during the month of January when the average temperature is $2^{\circ} F$

Substitute x = 2 in given equation to find the total snowfall

y = -0.368x + 18.483

y = -0.368(2) + 18.483

y = -0.736 + 18.483

y = 17.747

Therefore inches of snow fall during the month of January when the average temperature is 2°F is 17.747 inches

Kay [80]

$\cos 30=\frac{\sqrt{3}}{2}$

$\sin 30 = \frac{1}{2}$

$\tan 30=\frac{1}{\sqrt{3}}$

Now we insert that into the equation:

$\dfrac{\frac{\sqrt{3}}{2}}{1+\frac{1}{2}} = \frac{1}{\sqrt{3}}$

$\dfrac{\frac{\sqrt{3}}{2}}{\frac{3}{2}} = \frac{1}{\sqrt{3}}$

$\frac{\sqrt{3}}{3} = \frac{1}{\sqrt{3}}$

$\frac{\sqrt{3}}{3} = \frac{1}{\sqrt{3}}\cdot \frac{\sqrt{3}}{\sqrt{3}}\\$

$\frac{\sqrt{3}}{3} = \frac{\sqrt{3}}{\sqrt{3}\cdot \sqrt{3}}\\$

$\frac{\sqrt{3}}{3} = \frac{\sqrt{3}}{3}$

Step-by-step explanation:

There isn't exactly a step by step explanation.

7.92 is smallest because while all the ones with 7 in it have a 9 in the first digit, the second digit is the smallest out of those. you can work your way up from there
