Answer:
0
Step-by-step explanation:
P(E|F) = P(E and F)/P(F) = 0/0.2
Events that are mutually exclusive exclude each other. That means if one
occurs, the other is excluded. That means if one occurs, the other cannot
occur.
So that tells us that the probability of them both happening is impossible,
which mean P(E and F) = 0

Answer:
(D) 9/5
Step-by-step explanation:
One way to work this problem is to find % per cup for cereal and cups per % for milk, then multiply the product of those by 2.
The way we'll use here is to find the ratio of cups of milk to cups of cereal for the same % RDA.
We're given an amount of milk that has 25% of the RDA, but we want to find an amount that has 15% RDA. That amount of milk will be ...
(15%)/(25%)(1 cup milk) = 3/5 cup milk
This tells us that 3/5 cup milk has the same %RDA as 2/3 cup cereal. That ratio is ...
milk/cereal = (3/5)/(2/3) = (3/5)(3/2) = 9/10 cup of milk per cup of cereal
Then for 2 cups of cereal, we need ...
(9/10)(2 cups cereal) = 9/5 cups milk . . . . matches choice D
Answer:
OM = ON by using concurrency of Δs BOM and DON
Step-by-step explanation:
In the figure ABCD:
∵ AB // CD
∵ CB // AD
∵ In any quadrilateral If every two sides are parallel then
it will be a parallelogram
∴ ABCD is a parallelogram
∴ AC and BD bisects each other at O ⇒ (properties of parallelogram)
∴ OD = OB ⇒ (1)
∵ BC // AD
∴ m∠CBD = m∠ADB ⇒ alternate angles
∵ M ∈ BC , N ∈ AD , O ∈ BD
∴ m∠MBO = m∠NDO ⇒ (2)
∵ BD intersects MN at O
∴ m∠MOB = m∠NOD ⇒ (3) (vertically opposite angles)
From (1) , (2) and (3)
∴ ΔBOM ≅ ΔDON
∴ OM = ON
