Answer:
a
Step-by-step explanation:
the over all total equals 200 and you can not subtract the 2 variables to get the total you have to add them
Answer:
0.8 or 80%
Step-by-step explanation:
Let A and B be the events
<em>A: “The concert goer went to Orlampa Skydome”
</em>
<em>B: “The concert goer went to the Bithlo Megaplax”
</em>
<em>
</em>Then the probability P(A) that a concert goer went to Orlampa Skydome is
<em>P(A) = 120/200 = 0.6
</em>
Similarly,
<em>
P(B) = 100/200 = 0.5
</em>
<em>
</em>We are looking for P(A∪B), the probability that a concert goer went to Orlampa Skydome OR the Bithlo Megaplax.
We know that
P(A∪B) = P(A) + P(B) - P(A∩B)
but P(A∩B) is the likelihood that a concert goer went to Orlampa Skydome AND the Bithlo Megaplax.
Since the events are independent,
<em>
P(A∩B) = P(A)P(B) = 0.6*0.5 = 0.3
</em>
and
P(A∪B) = 0.6 +0.5 - 0.3 = 0.8 or 80%
Answer:
63.2
Step-by-step explanation:
So, we can break this shape into 2 shapes. A trapezoid and a rectangle.
For the trapezoid, we can do the formula.
((2.8 + 7.2)4)/2 = 20
Next, we can do the rectangle.
6 x 7.2 = 43.2
Now we can add them up and get our final answer.
43.2 + 20 = 63.2
Answer:
2(4x+1)
Step-by-step explanation:
We can factor out 2 in both parts to get that.
