Alan and austin are truck drivers. the dot plots show the number of deliveries they made per week during 14 weeks that were randomly selected from the previous year. the interquartile range of alan's data is , and the interquartile range of austin's data is . comparing the values of the interquartile range for alan’s and austin's data, data shows more variation in the data values.

144.50

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2

the answer is 5/14.

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
