SOLVE 10 PLEASE HELP ME I AM VERY CONFUSED. THIS IS DUE IN 10 MINUTES. WILL MARK AS BRAINIEST ANSWER IF CORRECT
2 answers:
Answer:
1) make an x, y chart for both equations
2) make random x values: (I chose -4 to 3)
3) plug in x values to find the solution to y values
4) the point that is a solution to both is (-2,2)
5) remember a variable can't be negative. so in the second equation don't forget to change the variable positive and number opposite of what it is

Answer:
85.56% probability that less than 6 of them have a high school diploma
Step-by-step explanation:
For each adult, there are only two possible outcomes. Either they have a high school diploma, or they do not. The probability of an adult having a high school diploma is independent of other adults. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
50% of adult workers have a high school diploma.
This means that
If a random sample of 8 adult workers is selected, what is the probability that less than 6 of them have a high school diploma
This is P(X < 6) when n = 8.
In which
85.56% probability that less than 6 of them have a high school diploma
