Answer:
9 cm
Step-by-step explanation:
Volume of a square pyramid, V = 1/3*(base area)*h
Where, base area = l*l = l^2
h = height
243 = 1/3(l*2)*h
l = h (base edge length = height)
243 = 1/3(l*2)*l
243 = 1/3(l^3)
729 = l^3
l = (729)^1/3
l = 9 cm
l = h = 9 cm
h = 9 cm

Answer:
1,000 miles
Step-by-step explanation:
set up the equation as
100x = d
where x equals the number of half inches between two points on the map
and d equals the distance between those points in real life
5 inches = 10 half inches so, plugged in the equation looks like
100(10) = d
simplify it to
1000 = d
and bam, the real distance is 1,000 miles
Answer:
A. Being above 180 centimeters and having black hair are independent of each other.
Step-by-step explanation:
These are instinctively two characteristics that are not related and the table data proves it.
If they were dependent, you would have only people with black hair above 180 cm, and all people with black hair would be above 180 cm.
You can be above 180 cm and have black, brown or blonde hair. The table shows a proportion of people > 180 cm about equal (around 30% of the sampling) for each hair color.
And people above 180 cm only represent 30% of the people with black hair.
