Answer:
the leaf is 8 meters away from the tree
Step-by-step explanation:
we can think of this problem as a right triangle where height represents a leg, and what flew the bird represents the hypotenuse
then we would have to find the other leg
for this we can use Pythagoras
h = hypotenuse = 17 meters
l1 = leg1 = 15 meters
l2 = leg2 = ?
h² = l1² + l2²
17² = 15² + l2²
17² - 15² = l2²
289 - 225 = l2²
64 = l2²
√64 = l2
8 = l2
the leaf is 8 meters away from the tree
Subtract to find the amount of the increase then divide the amount of increase by the original amount:
2.46 - 2.22 = 0.24
0.24/2.22 = 0.108
Multiply by 100 to get percent:
0.108 x 100 = 10.8%
Rounded to nearest whole number = 11%
20
step by step explanation:
7.1-0.6=6.5 is the answer
Answer:
a. The Venn diagram is explained in the attached word file.
0.61
b. Not independent
Step-by-step explanation:
a. The hypothetical 1000 table for given situation is
Adult(A) Not Adult (not A) Total
Travel outside (T) 610 170 780
Not Travel outside (not T) 110 110 220
Total 720 280 1000
P(Adult and travel outside)=P(A and T)=610/1000=0.61
b. Multiplication rule for independent events is
P(A and B)=P(A)*P(B)
P(A and T)=0.61
P(A)*P(T)=0.72*0.78=0.56
As P(A and T) is not equal to P(A)*P(T), so event "being an adult" and "travel outside" are not independent.
