Answer:
0.0019390
Step-by-step explanation:
10% of people do not like the taste of cilantro
A researcher takes a random sample of 15 people and surveys whether they like cilantro
Use the binomial distribution to compute the probability that exactly 6 of the people in the sample do not like cilantro.
Probability of success = 0.10 = p
Probability of failure = 0.9 =q
n = 15
r = 6
Formula : 
Hence the probability that exactly 6 of the people in the sample do not like cilantro is 0.0019390
Answer:
x=19
Step-by-step explanation:
We know that the interior angles of a triangle add up to 180 degrees. We already have one angle, the bottom one, so let's just get that out of the picture by subtracting it from 180. The other two angles add up to be 80 degrees. What we can do is combine them together and get 4x-4=80. We have 4x because of x+3x. It equals 80 because that's what the two angles together add up to be. What we want to do now is get x by itself. Subtract 4 from both sides and get 4x=76. Now, we divide by 4, to undo multiplication. We are left with x=19, and now we have our answer.
In that formula, we can know the equation is A=b+h÷2. A=6×8÷2, A=24. The answer is 24.
Simply 1 over 9 divided by 5 over 6 is 
or 
.
<u>Step-by-step explanation:</u>
Here we have , 1 over 9 divided by 5 over 6. It's known to us that x over y means x divides y i.e. x/y or 
. SO , for an instance we have 1 over 9 as 
and 5 over 6 as 
.Now ,its asked to simplify 1 over 9 divided by 5 over 6 i.e.
⇒ 1 over 9 divided by 5 over 6
⇒ ÷
⇒ 
⇒ 
⇒
⇒
Simply 1 over 9 divided by 5 over 6 is or .
