Which of the following is an example of independent events?

Mathematics
1 answer:
Mashcka [7]3 years ago
5 0

Answer:

A. Getting tails from a coin toss and drawing a king from a standard

deck of cards.

Step-by-step explanation:

In probability, independent events are two events that do not affect the outcome of the other. In the first option, whether or not tails is flipped in no way changes the likelihood of a king being drawn. So it is independent because each event can be performed independently of the other.

However, all of the other options are "without replacement". This is a common term used to describe dependent events because since the item is not being replaced, the sample size is changed. This changes the probability of the next outcome. They are called dependent events because the second event depends on the first.

jasenka [17]

Answer:

<em>The weight of the parcel is approximately 6 kilograms.</em>

Step-by-step explanation:

The weight of the parcel is  12 lbs and 8 oz.

1 lb = 16 oz

So,  8 oz = \frac{1}{2}lb = 0.5 lb.

<u>That means,  12 lbs and 8 oz</u> = (12 + 0.5) lbs = 12.5 lbs

Now, 1 lb = 454 g

So,  12.5 lbs = (12.5 × 454) g = 5675 g

As,  1 kilogram = 1000 g

That means, 1 g = 0.001 kilogram

So,  5675 g = (5675 \times0.001) kilograms= 5.675 \approx 6 kilograms. <em>(Rounded to the nearest whole kilogram)</em>

Thus, the weight of the parcel is approximately 6 kilograms.

Which is closest to the value of w in the triangle below?
mr Goodwill [35]

Answer: B. 2.5 in

Step-by-step explanation:

From the given right angle triangle,

the hypotenuse of the right angle triangle is the unknown side.

With m∠32 as the reference angle,

the adjacent side of the right angle triangle is 4 in

the opposite side of the right angle triangle is w

To determine w, we would apply

the tangent trigonometric ratio which is expressed as

Tan θ = opposite side/adjacent side. Therefore,

Tan 32 = w/4

w = 4tan32 = 4 × 0.625

w = 2.5 in
