Answer: Fourth option is correct.
Step-by-step explanation:
Since we have given that
A be the event that the person has 2 siblings.
B be the event that the person does not have a pet.
Since they are not independent events.
Because if P(A|B) = 0.18
in case if they are independent events then, P(A|B) = P(A).
But here P(A) = 0.4
So, they are not independent events.
Hence, Fourth option is correct.
Answer:
Side a = 23 Side b = 28 Side c =46
Step-by-step explanation:
First set up your equation witch is x-5+x+x-5*2=69
Then Simplify x+-5+x+x+-10=69
Then combine like terms 3x-15=69
Add 15 to both sides
After you will get 3x=84
then divide both sides by 3
You will get x=28
Then go back to your question it says THE FIRST IS 5 CM SHORTER THAN THE SECOND SIDE. THE THIRD SIDE IS TWICE AS LONG AS THE FIRST SIDE. So that tells you that to find A, you do 28-5=23, to side b is x so its 28, and to find side c you do 28-5*2=46. So A=23, B=28, and C=46.
Combine 2a^3+5a-7 and 5a^2-6a+12.
Rewrite this so that the second expression is beneath the first:
2a^3+5a-7
5a^2-6a+12
Combine like terms. The highest order term is 2a^3:
2a^3+0a^2 +5a-7
+5a^2 - 6a+12
----------------------------
2a^3 + 5a^2 - a + 5 (answer)
Note how these terms are in descending order by power of a.
