Answer:
of the 4 people that have a sister, 2 of them have a brother
Step-by-step explanation:
probability of B given A
given that the person has a sister, what is the probability they have a brother
P (B/A) = 1/2
with this venn diagram
of the 4 people that have a sister, 2 of them have a brother
If you are being asked to simplify, just combine like terms; such as, all the g’s and all the numbers so, your answer should look something like: 7g+6
M is the centroid and the centroid divide the line in 1:2 ratio . So M divide BQ in 1:2 ratio and the total length of BQ is 18.
Therefore BM is one third of 18 . ANd one third of 18=6
So BM =6 and MQ=12 .
The answer to this question is B. 130cm^2.
Using the volume formula for a sphere (V = (4/3)πr^3) you can plug in the values that we know to find the radius to be around 3.22117 cm. You can then use the area of a sphere formula (A = 4πr^2) to find the area. Hope this helps :)
Answer:
12, 8, and 4
Step-by-step explanation:
a + d + a + a - d = 24
3a = 24 ⇒ [ a = 8 ]
and (a + d)² + a² + (a - d)² = 224
3a² + 2d² = 224
2d² = 224 - 192 = 32
d² = 16
[ d = ±4 ]
∴ The first three terms to A.P are
a + d = 8 + 4 = 12
a - = 8
a - d = 8 - 4 = 4
∴ Three terms are 12 , 8, and 4
