Answer:
x=17
Step-by-step explanation:
7x+10+3×=180
10x+10=180
-10. -10
10x/10=170/10
x=17
Answer:
∠a = 42.5°
∠b = 87°
∠c = 174°
∠d = 90°
∠f = 131°
Step-by-step explanation:
∠a = 85°/2 = 42.5°
∠b = 360° -110° - 76° = 174°/2 = 87°
∠c = 360° -110° - 76° = 174°
∠d = 90°
∠f = 360° - 101° - (64° x 2) = 131°

Answer:
- <em>B) 41 − 45; 46 − 50; 51 − 55; 56 − 60 </em>
Explanation:
When you build a <em>histogram </em>the intervals must be of the same size. About 4 to 8 intervals is good but it also depends on the number of data and the range of those data.
Option D has only two intervals. That is too few. Thus, this is discarded. Three intervals also seems few. Thus, option C, is not good.
The option A shows intervals of different size:
- 46 - 41 = 4
- 49 - 46 = 3
- 52 - 49 = 3
- 56 - 53 = 3
Thus, this is not good either.
The optio B seems good:
Interval Frequency
- 45 - 41 = 4 3
- 50 - 46 = 4 4
- 55 - 51 = 4 4
- 60 - 56 = 4 1
Hence, the correct answer is B) 41 − 45; 46 − 50; 51 − 55; 56 − 60
