Answer:
Event A = { Chevrolet , Buick }
Event B = { Ford , Lincoln }
Event C = { Toyota }
Step-by-step explanation:
- Mutually exclusive events are such that their probability of coming true simultaneously is zero. If we consider set notations we could say.
P (A & B) = P (B & C) = P (A & C) = 0
- In our case these events A,B, and C can be defined as:
Answer:
Event A = { Chevrolet , Buick }
Event B = { Ford , Lincoln }
Event C = { Toyota }
Answer:
30 years
Step-by-step explanation:
Shobo's age=x years
His mother's age= 6 times of Shobo's age= 6x years
Five years from now
Shobo's age= (x+5) years
According to the problem
x+5=1/3 of his mother's present age
x+5=6x/3
x+5=2x
5=2x-x
5=x
Therefore Shobo's present age is 5 years
His mother's age =6x
6x5=30 years
Answer:
25
Step-by-step explanation:
0.28x = 7
x = 25
Answer:
3) The function's leading coefficient is negative.
Explanation:
(1) Is not the answer because when x = 3, f(x) = 0.
(2) Is not the answer because when f(x) = -3,
x = 0.
(4) Is also not the answer because the y-values on both sides of (1, -4) are mirroring each other.
Therefore,
(3) is the answer, by elimination, but also because there is not proof of the leading coefficient being negative, as we don't see the original equation.
I hope this helped! :)
i.e. In every 10 honey bees live !
<u>Step-by-step explanation:</u>
We have , A population of 6,000 honey(Correction as this isn't given in question ) bees lives in a rectangle-shaped area of the woods that is 30 meter long by 20 meters wide. We need to find What is the population density of the honey bees. Let's find out:
We know that ,
Population density = (Population) / (Land Area)
Now , Area of rectangle =
⇒
⇒
⇒
Hence ,
⇒
⇒
Therefore , i.e. In every 10 honey bees live !
