Choose the correct symbol for interval notation when a value is to be included in the solution
A. Parenthesis
ex
you had
x3 when x=8
it will be
(8)3
To make a square for x²+bx=c, add(

)²on both side
in this case, b is-3/4, half of b is -3/8, and (-3/8)² is 9/64, so you add 9/64 to both side.
Answer:
x=11
Step-by-step explanation:
10 less than three times a number is 23
3x-10=23
3x=33
x=11
Answer:

Step-by-step explanation:
Let A and B events. We have defined the probabilities for some events:

Where A' represent the complement for the event A
The complement rule is a theorem that provides a connection between the probability of an event and the probability of the complement of the event. Lat A the event of interest and A' the complement. The rule is defined by:
So for this case we can solve for P(A) like this:

And now we can find
using the total probability rul given by:

And if we replace the values given we got:

And that would be the final answer.
