Answer:
120x^3
Step-by-step explanation:
exponent rule --> a^b x a^c = a^b+^c
10^-6 x 10^7 = 10^6 + ^7
add / subtract numbers -- > -6 + 7 = 1
=2XX x 6X x 10
aponent rule --> a^b x a^c = a^b+^c
xxx = x^1 + ^1 + ^1
= 2 x 6x^1 + ^1 + ^1 x 10
= 2 x 6x^3 x 10
= 120x^3
It would be: 81*37.5 / 100 = 30.375
There is a 1/3 chance that a red marble would be chosen.
To find out you put add up the marbles, so they will make 12 marbles.
Since there are 4 red you put 4/12.
4/12 simplified is 1/3.
So the chance of a red marble being picked is 1/3.
Answer:
Option (A)
Step-by-step explanation:
AE and RV are the two line segments intersecting at a point N.
Therefore, ∠ANR ≅ ∠ENV [Vertical angles are equal in measure]
(8x + 12)° = (5x + 57)°
8x - 5x = 57 - 12
3x = 45
x = 15
Since, m∠ENV = 5(15) + 57
= 75 + 57
= 132°
Therefore, Option (A) will be the answer.
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%
