Answer:
Probability of getting at least 9 out of 18 correctly is 0.0043
Step-by-step explanation:
We have
n = 18
p = 1/5 for correct answer
q = 4/5 for wrong answer
P( 9
X
18) = 1 - P(0
X
8)
= 1 - 0.9957
=0.0043
Answer:
answer is below
Step-by-step explanation:
tan p = 32/24 = 4/3
tan q= 24/32 = 3/4
First off you need to take the square root of both sides and it leaves you with (x)(2x)= 15 then you multiple the x and it gives you 2x^2=15 then you divide by 2 and it gives you 7.5 then you take the square root of that to cancel the x^2 and it gives you x=2.7
