Answer:
1/7
Step-by-step explanation:thats it
Answer:
we need to shift decimal then divide
Step-by-step explanation:
For this case we have the following equation:

From here, we must clear the value of x.
Adding By on both sides:

Then, dividing both sides by A we have:

Answer:

x equals the quantity B times and plus C all over A
Using the binomial distribution, it is found that there is a 0.81 = 81% probability that NEITHER customer is selected to receive a coupon.
For each customer, there are only two possible outcomes, either they receive the coupon, or they do not. The probability of a customer receiving the coupon is independent of any other customer, which means that the binomial distribution is used to solve this question.
Binomial probability distribution
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem:
- For each customer, 10% probability of receiving a coupon, thus
. - 2 customers are selected, thus

The probability that <u>neither receives a coupon is P(X = 0)</u>, thus:


0.81 = 81% probability that NEITHER customer is selected to receive a coupon.

more than the quotient of -36 and -4 is called a word statement.
Thus, we need to convert it into its algebraic equation and then solve.
Before that, let’s identify each word first
=> 9 is an integer
=> more than = means add or +
=> quotient = means answer to division
=> - 36 and -4 are negative integers
Now, let’s make the equation
=> 9 + (-36 / -4 ), since both numbers to be divided are negative, the quotient
would be positive
=> 9 + 9
=> 18
