If a coin is tossed and a number cube is rolled, what is the probability that the coin shows heads and the number cube shows 3

1 answer:

6 0

Assuming the number cube is a die numbered 1-6,
The probability of flipping a coin and getting heads and the probability of rolling a 3 on the die are independent of each other.

-There are two sides of a coin, heads and tails. You have two possible results from the coin - heads, or tails. You have a 1 in 2 probability of getting either.

-There are six sides of a die. There are six possible results from the die - 1, 2, 3, 4, 5, and 6. You have a 1 in 6 probability of getting any of the results.

The probability of both happening (<em>and</em>) can be determined by multiplying the two probabilities.

Hope this helps!

Solve for d: 0.5(2d-6)=0.2(4x-10)

Law Incorporation [45]

Answer:d=0.8x+1

Step-by-step explanation:

To solve 0.5(2d-6)=0.2(4x-10)

Open the brackets

We get

d-3=0.8x-2

To make d the subject of formular

d=0.8x-2+3

d=0.8x+1

a larger gear wheel has 40 teeth and a small gear wheel has 25 teeth. if the larger one makes 100 revolutions in a minute, how m

nevsk [136]

Lets calculate gear ration T2/T1
so the gear ratio will be 1.6 it simply means dat if u rotate large gears one full revolution it tends to turn another short wheel to 1.6 revs, so in ur qtion the large whell revs 100 den u must multiply wid 1.6*100= 160 revs

Which figures demonstrate a translation?

Nuetrik [128]

Answer:

3rd and 4th Options are correct choices.

Step-by-step explanation:

We have been given a graph and we are asked to find which of the given figures demonstrate translation.

Since we know that in translation every point of the object must be moved in the same direction and for the same distance. By translation we can shift a figure in upward, downwards, left and right directions.

Now let us see our given choices one by one.

1. Upon looking at figures represented by 1st option we can see that both figures are mirror images to each other. Since we can get mirror images reflecting the pre-image over an axis of symmetry. So the given figures are result of reflection, therefore, 1st option is not a correct choice.

2. We can see that the figures represented by 2nd option are similar. One figure is smaller and other is larger. Since we get a similar image by dilating our pre-image. Therefore, these figures are result of dilation and 2nd option is not correct indeed.

3. We can see that figures represented by 3rd option are same and these figures are result of shifting. We can see that 1st figure is shifted to right to get the second figure, therefore, 3rd option is a correct choice.

4. The figures represented by 4th option are same and these figures are result of shifting. We can see the figure in the bottom is result of shifting the upper figure downwards and then to right. Therefore, 4th option is a correct choice.
