1 1/3. One whole number is 3/3 so 3/3=1 then u put 1/3
Rewrite as
= 24
Multiply both sides by 3 to isolate 2x².
2x² = 72
Divide both sides by 2 to isolate x².
x² = 36
Square root both sides to isolate x.
x = -6 or 6
-6 is smaller than 6.
The smallest solution is -6.
Answer:
0.81 = 81% probability that a randomly selected student is taking a math class or an English class.
0.19 = 19% probability that a randomly selected student is taking neither a math class nor an English class
Step-by-step explanation:
We solve this question working with the probabilities as Venn sets.
I am going to say that:
Event A: Taking a math class.
Event B: Taking an English class.
77% of students are taking a math class
This means that
74% of student are taking an English class
This means that
70% of students are taking both
This means that
Find the probability that a randomly selected student is taking a math class or an English class.
This is , which is given by:
So
0.81 = 81% probability that a randomly selected student is taking a math class or an English class.
Find the probability that a randomly selected student is taking neither a math class nor an English class.
This is
0.19 = 19% probability that a randomly selected student is taking neither a math class nor an English class
Twice means two times something so2a. Four more than means adding for so your answer is 2a+4
Answer:
see the explanation
Step-by-step explanation:
Observing the picture
1) For y=-1
The answer is undefined (there is no corresponding value for x)
2) For y=0
we have the points (-3,0) and (6,0)
therefore
x=-3, x=6
3) For y=2
we have the points
(-2.25,2)
(0.75,2)
(4,2)
therefore
x=-2.25, x=0.75, x=4
3) For y=3
we have the points belong to the interval [-2,0]
so
