Examine this image and choose the most accurate statement base on relative dating.
Vlada [557]

Hello!

One of the most basic examples of relative dating, specifically in this case, would be the law of superposition. This simply states that out of many layers of rock, the oldest would be at the bottom and the youngest on top, so therefore the age of the fossils inside the rock would also increase when going down the layers. Therefore, we see that layer a is the oldest, and layer g is the youngest.

This disproves the first answer choice - the fossils in layer g are the youngest, not the oldest. Now, when comparing Layer F and D, we see that the rock layer F is above layer D. This means that layer F is younger than layer D (and same for the fossils in those respective layers). The third choice is incorrect as layer A would be older than F as it is beneath layer F.

Therefore, this means your second choice, or the fossils in layer F are newer than the fossils in layer D, is correct.

Hope this helps!

Describe why heart failure is so often referred as "congestive" heart failure ?
telo118 [61]

Answer:

Heart failure — sometimes known as congestive heart failure — occurs when the heart muscle doesn't pump blood as well as it should. When this happens, blood often backs up and fluid can build up in the lungs, causing shortness of breath.

In a standard deck of playing cards, there are four suits (red suits hearts and diamonds, black suits spades and clubs). Each su
Lapatulllka [165]

Answer:

Probability can be calculated by dividing the number of possible outcomes by the total number of outcomes.

probability= \frac{possible outcomes}{total outcomes}

There are 4 suits each with 13 cards (10 number and 3 face cards)

Total number of cards = 13 x 4 = 52

1. Probability of having a face card:

There are 3 face cards in each suite and there are four suits in total. Thus, total number of face cards = 3 x 4 = 12

Total number of cards in a deck = 52

Probability of drawing a face cards = \frac{12}{52} = 0.231

2. Probability of drawing a red card:

There are two red suits (red suits heart and red diamonds) each having 13 cards. Thus, total number of red cards = 13 x 2 = 26

Total number of cards in a deck = 52

Probability of drawing a red card = \frac{26}{52} = 0.5

3. Probability of drawing a red face card:

There are two red suits (red suits heart and red diamonds) each having 3 face cards. Thus, total number of red cards = 3 x 2 = 6

Total number of cards in a deck = 52

Probability of drawing a red card = \frac{6}{52} = 0.115
