Hey I need this question fast so plz answer

Step-by-step explanation:

The square in the left lower corner means that the angle is a right angle or 90 degrees.

The two given angles must add to 90 degrees.

x + 42 + 3x = 90              Combine the left

4x + 42 = 90                    Subtract 42 from both sides

4x = 90 - 42                     Combine

4x =  48                            Divide both sides by 4

4x/4 = 48/4

x = 12

Now what do you need?

x = 12

angle 1 = 3x = 3*12 = 36

angle 2 = x + 42 = 12 + 42 = 54

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.  

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
