Answer:

\alpha = 60°,\:\beta = 30°, \: 90°

Step-by-step explanation:

Arccos( \frac{ \sqrt{3} }{2} ) =  \beta  \\ Arccos(  \cos \: 30 \degree ) =  \beta  \\30 \degree =  \beta  \\  \therefore \:  \alpha  = 60 \degree \\ remaining \: angle = 90 \degree \\

Answer:

1.0 ; 1.1 ; 1.7 ; 2.0 ; 2.5

Step-by-step explanation:

Given the following :

√1.001 ,√1.1212 ,√2.895, √4.005 ,√6.2533

The square root to the nearest tenth :

Using calculator :

√1.001 = 1.0004998 = 1.0

√1.1212 = 1.0588673 = 1.1

√2.895 = 1.7014699 = 1.7

√4.005 = 2.0012496 = 2.0

√6.2533 = 2.5006599 = 2.5

A coordinate grid is placed over a map and every unit represents 1 mi. The point at (3, 8) represents the location of the baseba
alexira [117]
The distance between 2 points ( x_{1}, y_{1}) and ( x_{2}, y_{2}) on the coordinate plane is \sqrt{(x_{2}-x_{1})^2-(y_{2}-y_{1})^2}
So the distance between the given points is \sqrt{(7-3)^2+(-2-8})^2}= \sqrt{4^2+(-10)^2}= \sqrt{16+100}=  \sqrt{116}=10.8
As every unit is 1 mile, so the distance should be 10.8*1=10.8miles.

Hope this helps.

60 POINTS!!!
Bingel [31]

A) The IQR is Q3 - Q1 Q3 is the right edge of the blue box and Q1 is the left edge.

IQR = 25-1 = 24

B) Median values are the line inside the blue boxes:

20-5 = 15

C) the male distribution is asymmetrical and the female distribution is more symmetrical. Because the men are asymmetrical it would be best to describe the distribution using the Median. The women are symmetrical so it would be best to use the mean.

Overall the mean is the most popular/ best way to measure the center.

D) the outlier could be the first day the movie was shown
