There are several different types of charts and graphs. Each type of chart and graph has required elements. What required elements should be present on a bar chart for it to be complete and accurate? A. An appropriate title
B. The horizontal axis should be labeled
C.The vertical axis should be labeled
D.All of the above
E.None of the above.
Answers
The correct answer is D. All of the above
Explanation:
A bar chart is a type of graph that presents information by using bars; these bars show the relationship between two factors or variables presented in the Y or vertical axis and the X or horizontal axis. For example, you might present the time 5 students spend doing homework by including the hours on the Y-axis and the name of each student on the X-axis.
In this context, for the reader to understand the information presented in the graph it is essential that each of the axes is labeled, in this way the reader will know which variables or factors are represented. Also, in most cases, you will an appropriate title that introduces the general situation that is presented. Thus, for a bar chart to be accurate you will need all of the above.

Which of the following constants can be added to x2 + x to form a perfect square trinomial?
Three friends — let’s call them X, Y , and Z — like to play pool (pocket billiards). There are some pool games that involve three players, but these people instead like to play 9-ball, which is a game between two players with the property that a tie cannot occur (there’s always a winner and a loser in any given round). Since it’s not possible for all three of these friends to play at the same time, they use a simple rule to decide who plays in the next round: loser sits down. For example, suppose that, in round 1, X and Y play; then if X wins, Y sits down and the next game is between X and Z. Question: in the long run, which two players square off against each other most often? Least often? So far what I’ve described is completely realistic, but now we need to make a (strong) simplifying assumption. In practice people get tired and/or discouraged, so the probability that (say) X beats Y in any single round is probably not constant in time, but let’s pretend it is, to get a kind of baseline analysis: let 0 < pXY < 1 be the probability that X beats Y in any given game, and define 0 < pXZ < 1 and 0 < pY Z < 1 correspondingly.

0.430625 = 0.431
Step-by-step explanation:
Let W represent winning, D represent a draw and L represent a loss.
12+ points can be garnered in each of the following ways.
6W 0D 0L
5W 1D 0L
5W 0D 1L
4W 2D 0L
4W 1D 1L
4W 0D 2L
3W 3D 0L
The probability of getting 12+ points is the sum of all these 7 probabilities.
Knowing that P(W) = 0.5
P(D) = 0.1
P(L) = 0.4
P(6W 0D 0L) = [6!/(6!0!0!)] 0.5⁶ 0.1⁰ 0.4⁰ = 0.015625
P(5W 1D 0L) = [6!/(5!1!0!)] 0.5⁵ 0.1¹ 0.4⁰ = 0.01875
P(5W 0D 1L) = [6!/(5!0!1!)] 0.5⁵ 0.1⁰ 0.4¹ = 0.075
P(4W 2D 0L) = [6!/(4!2!0!)] 0.5⁴ 0.1² 0.4⁰ = 0.09375
P(4W 1D 1L) = [6!/(4!1!1!)] 0.5⁴ 0.1¹ 0.4¹ = 0.075
P(4W 0D 2L) = [6!/(4!0!2!)] 0.5⁴ 0.1⁰ 0.4² = 0.15
P(3W 3D 0L) = [6!/(3!3!0!)] 0.5³ 0.1³ 0.4⁰ = 0.0025
The probability of getting 12+ points = 0.015625 + 0.01875 + 0.075 + 0.09375 + 0.075 + 0.15 + 0.0025 = 0.430625
Find the amount of the time.
Answers
Answer:
The amount of time is 8 years
Step-by-step explanation:
Simple interest refers to the interest produced by initial capital over a period of time. This does not accumulate to the capital to produce the interests of the following period, so the interest generated or paid in all periods is the same, while the interest rate and term dont vary.
The amount of interest paid or charged depends on three important amounts: Capital, rate and time. This is expressed by the following equation:
I = P * r * t
Where:
- I = interest.
- P = initial capital.
- r = interest rate in decimals (it is usually a given data in percentage, which you must divide by 100 to get the value in decimals).
- t = time in years.
In this case I has a value of $ 720, P has a value of $ 1000 and r of 9%, which making the conversion to decimal is 0.09
Replacing in the equation you get:
720=1000*0.09*t
Multiplying 1000 * 0.09 you get:
720=90*t
Dividing both sides by 90, in order to isolate t, you get:
8=t
Remembering that the value of t is expressed in years, this means that the amount of time is 8 years.
I / PR = T
I = 720
P = 1000
R = 9% = 0.09
now we sub
720 / (1000)(0.09) = T
720 / 90 = T
8 = T <===

divide both sides by 2/13
