Answer:
Yes, it's a right-angle triangle
Step-by-step explanation:
3 root 2 is 4.24
3 root 3 is 5.2
3 root 5 is 6.71
3 root 5 is the longest side, so must be the hypotenuse.
a^2 + b^2 = c^2
(3 root 3)^2 + (3 root 2)^2 = c^2
45 = c^2
Square root both sides
C = root 45
( simplified to C= 3 root 5)
Thus, it is a right-angle triangle.
(Root means a square root)

Answer:
13.34
Step-by-step explanation:
The distance between two points is given by
d =sqrt( (x2-x1)^2 + (y2-y1)^2)
= sqrt((6-3)^2 + (9--4)^2)
= sqrt(( 3^2 + (9+4)^2)
= sqrt( 9 + 13^2)
= sqrt( 9+169)
= sqrt(178)
=13.34166406

The answer to the question
Answer:
0.3
Step-by-step explanation:
We can use Bernoulli estimation to solve this. P(g) = 0.8, probability of not growing into healthy plant P(n) = 1-P(g) = 1 - 0.8 = 0.2
Using the Bernoulli approximation:
P(n=2) = 10C2 * P(n)^2 * P(g)^8
P(n=2) = 45 * 0.2^2 * 0.8^8
P(n=2) = 0.30
