Answer:
The probability of 9 successes in 10 trials in the binomial probability experiment is 0.387
Step-by-step explanation:
In this question, we are asked to compute the probability of 9 successes in 10 trials , given that the probability of success is 0.9
Firstly we need to know which approach we are going to use to solve this problem. To compute this probability, the approach to use is the Bernoulli approximation. To use this, we need to know the probation failure.
We can represent this by let’s say q. The probability of failure q in this case is 1-p = 1-0.9 = 0.1
Let us figure out the Bernoulli expression here. It would look like;
nCx * p^x * q^(n-x)
Let’s impute the value properly, we have;
10C9 * 0.9^9 * 0.1^1
= 10 * 0.9^9 * 0.1 = 0.387
Answer:
10
Step-by-step explanation:
If she multiplied by 10 imagine it as the decimal moving once to the right per every 0. So 2.7 x 10 = 27
c. because when you di the math it adds up
So what u want to do is find out how much it is per oz, so Mini is $.10 per oz, family is $.08 per oz, and economy is $.09 per oz
Family 28oz is the best buy
To solve:
-2x = 34
----- -----
-2 -2
(-2x means -2 times x, so to undo this we need to divide by -2 on both sides)
x = -17
Then you do basic division (knowing that a positive divided by a negative results in a negative answer). And that's it!
