Answer:
2/3p - 3/4 = 2/10
2/3p = 38/40
p = 57/40 = 1 17/40
Step-by-step explanation:
3/5=6/10 so Naomi got 138.
Luke got 69.
And Natalie got 23.
Answer:
The correct answer is 0.15
Step-by-step explanation:
According to the given scenario, the probability is as follows:
X
Bin (n,p)
Here
n = 8
p = 0.20 or 20%
Now this is a binomial probability distribution

= 0.15
Hence, the correct answer is 0.15
Answer:
b = 6 sqrt(2)
Step-by-step explanation:
Since this is right triangle, we can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
3^2 + b^2 = 9^2
9+b^2 = 81
b^2 = 81-9
b^2 = 72
Take the square root of each side
sqrt(b^2) = sqrt(72)
b = sqrt(36*2)
b = 6 sqrt(2)
4 x 4 = 16
5 x 5 = 25
6 x 6 = 36
