Answer:
The probability that a high school member selected at random is on the swim team is
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: High school student.
Event B: Is on the swin team.
Probability of selecting a high school student:
Of the 1500 students, 200 are on high school. So
Probability of selecting a high school student who swims:
Of the 1500 students, 45 are high school students who swim. So
What is the probability that a high school member selected at random is on the swim team?
The probability that a high school member selected at random is on the swim team is
Plus a negative value becomes subtraction:
-12 + -23 = -12 -23 = -35
y = florida's number of countries x = countries in Arizona
y=5x-8
Answer:
The answer is C 35+12<em>c</em> ≤ 145
Step-by-step explanation:
Answer: (x−2)(x−2)
The middle number is -4 and the last number is 4.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get -4
Multiply together to get 4
Can you think of the two numbers?
Try -2 and -2:
-2+-2 = -4
-2*-2 = 4
Fill in the blanks in
(x+_)(x+_)
with -2 and -2 to get...
(x-2)(x-2)
Answer:
(x−2)(x−2)
so the answer is D.
