2 sqrt(3) -2sqrt(3)
this is rational because it is zero
DC/AC=EC/BC
x/(x+3)=10/16
10(x+3)=16x
10x+30=16x
30=6x
x=5
DC=x=5
DC=5 units long
10/16=DE/AB, DE=y
10/16=y/10
16*y=10*10
y=6.25≈6.3
DE≈6.3
When r is closest to 1, it is a strong positive correlation. When r is closest to -1 it is a strong negative correlation. When r is about 0.8 or anything similar, it is a weak positive. Similar to if r is -0.8 it would be a weak negative correlation. Hope this helps.
Answer:
Number of people fit in 6 feet by 6 feet room = 12 people
Step-by-step explanation:
Given:
Number of people fit in 9 feet by 4 feet room = 12 people
Find;
Number of people fit in 6 feet by 6 feet room
Computation:
Surface area of 9 feet by 4 feet room = 9 x 4
Surface area of 9 feet by 4 feet room = 36 feet²
So,
Surface area of 6 feet by 6 feet room = 6 x 6
Surface area of 6 feet by 6 feet room = 36 feet²
Surface area of both rooms are equal. so number of people are also equal
Number of people fit in 6 feet by 6 feet room = 12 people
