Answer:
A rational number is a number that can be written as a fraction, is a whole number, is a decimal that stops like 3.35, or is a repeating decimal
Since the lines are parallel and you know the slope of

is -2, you know the slope of line

will also be -2. You can see on the coordinate grid that line

crosses the y-axis at -1. When you piece all of these facts together into slope-intercept form you get
= -2x - 1.
Answer:
The square of a prime number is prime
Using the binomial distribution, it is found that there is a 0.027 = 2.7% probability that he makes exactly 1 of the 3 free throws.
For each free throw, there are only two possible outcomes, either he makes it, or he misses it. The results of free throws are independent from each other, hence, 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:
- He makes 90% of the free throws, hence
.
- He is going to shoot 3 free throws, hence
.
The probability that he makes exactly 1 is P(X = 1), hence:


0.027 = 2.7% probability that he makes exactly 1 of the 3 free throws.
