To find the mean add up each value and divide by the number of values
Planted society- 40+20+16+20+17+12+15=140
140/7=20
Bees park- 25+12+9+15+35+20+6+30=152
152/8=19
planted society’s mean was larger
C 25 because in 2 cases there's 50 and 1 is half of 2 so 50÷2 equals 25 and that's how much in a case
Answer:
height = 9.28m
Step-by-step explanation:
Sum of angle in a triangle = 180°
To find the third angle, we have
180° = 71° + 62° + α
180° = 133° + α
α = 180° - 133°
α = 47°
To find the height use sine rule
h/sin47° = 12/sin 71°
h(sin71°) = 12sin47°
h = 12sin47° / sin71°
h = 12(0.7314) / 0.9455
h = 8.7768/0.9455
h = 9.28m
That answer is a quadrilateral has 4 right angles. yeah
45.803 = 40 + 5 + 0.8 + 0.003 need any explanations just ask
hope this helps!
