Step 1
State the formula for the probability of an event
The required number of event= The students with 2 or more pets= 15+7+3+2+0 = 27
Total number of events=4+11+15+7+3+2+0=42
Step 2
Estimate the probability that a randomly selected student from this class has 2 or more pets.
Answer; Option C 27/42 or approximately 0.64
ratio of medium shirts to large shirts
63/27
=7:3 [Ans]
D. because linear is a straight line. and the graph is a parabola and the ends are arrows which make it continuous
Step-by-step explanation:
The root is
-sqr root of 5.
First, we put these roots in the forn of
where a is the root
So we have
To get rid of that square root, let have another root that js the conjugate posive root of 5.
Which will gives us a rational coeffeicent of degree 4.
Why we didn't do
?
Because
If we foiled out we will still have a irrational coeffceint.
The fraction 12/16 has the same .75 value as the fraction 3/4
