A^2+b^2=C^2
=
4+144=148
The square root of 148 is 12.165
round it down to 12
Hope this helps
Answer:
x^(2) + 14 x + 49
Step-by-step explanation:
Answer:
21.25
Step-by-step explanation:
We can use the Pythagorean theorem since we know the legs
a^2+b^2 = c^2
12.75 ^2 + 17^2 = c^2
162.5625+289= c^2
451.5625 = c^2
Take the square root of each side
sqrt(451.5625) =sqrt( c^2)
21.25 = c
Answer:
1. 1/120
2. 7/24
Step-by-step explanation:
n = 10
Number of defective = 3
1. Probability of all defective =
(Number of defective/n) x (number of defective -1/n -1)...(number of defective -n/n-1)
=3/10 x 2/9 X 1/8
= 6/720
= 1/120
2. probability of none defective
Since 3 are defective, those that are not defective = 7
The probability is therefore:
7/10 x 6/9 x 5/8
= 210/720
= 7/24.
