The linear equation 400(3/5)^n-1 represent and satisfy the conditions which is given in the statement. Thus option A is a correct option.

According to the statement

We have to find that the which equation represent the all given conditions in the statement.

So, For this purpose, we know that the

A linear equation is an equation in which the highest power of the variable is always 1.

The given information is:

A ball is dropped from a height of 400 feet. Each time it hits the ground,it reaches a height that is three-fifths its previous height.

From this statement, it is clear that the height of ball decreases to the three-fifth of the original height before touching the ground.

there is decrease in the height.

Hence the equation 400(3/5)^n-1 represent and satisfy the decrease of the height of the ball.

So, The linear equation 400(3/5)^n-1 represent and satisfy the conditions which is given in the statement. Thus option A is a correct option.

Answer:

  the probability is 2/9

Step-by-step explanation:

Assuming the coins are randomly selected, the probability of pulling a dime first is the number of dimes (4) divided by the total number of coins (10).

  p(dime first) = 4/10 = 2/5

Then, having drawn a dime, there are 9 coins left, of which 5 are nickels. The probability of randomly choosing a nickel is 5/9.

The joint probability of these two events occurring sequentially is the product of their probabilities:

  p(dime then nickel) = (2/5)×(5/9) = 2/9

_____

<em>Alternate solution</em>

You can go at this another way. You can list all the pairs of coins that can be drawn. There are 90 of them: 10 first coins and, for each of those, 9 coins that can be chosen second. Of these 90 possibilities, there are 4 dimes that can be chosen first, and 5 nickels that can be chosen second, for a total of 20 possible dime-nickel choices out of the 90 total possible outcomes.

  p(dime/nickel) = 20/90 = 2/9

Vikentia [17]
The correct answer is B. cm3

This is saying "centimeters cubed", and is true because you are multiplying 3 dimensions of centimeters, width*length*height, to get the answer. Thus, you are multiplying the numbers <em>and </em>the units. 30*30*25 and cm*cm*cm
