I will mark Brainliest Please help worth 30 pointsThe distance, y, in centimeters, of an ant from a hole in the tree for a certa

in amount of time, x, in seconds, is shown in the graph:
A graph titled Motion of Ant is shown. The graph shows time in seconds on the x-axis and the Distance from Hole in centimeters on the y-axis. The scale on the x-axis is shown from 0 to 6 at increments of 1, and the scale on the y-axis is shown from 0 to 12 at increments of 2. The graph has 3 straight lines. The first line is labeled P and joins ordered pairs 0, 0 and 2, 6. The second line is labeled Q and joins ordered pairs 2, 6 and 3, 6. The third line is labeled R and joins ordered pairs 3, 6 and 5, 0.



Part A: Is the graph linear or nonlinear? Explain your answer. (2 points)


Part B: In which segments is the graph increasing, decreasing, and constant? (3 points)


Part C: In your own words, describe the motion of the ant, as shown on the graph. (5 points)

Answer:

The graph shows the depth, y, in meters, of a shark from the surface of an ocean for a certain amount of time, x, in minutes:

A graph titled Distance Vs. Time is shown. The x axis is labeled Time in minutes and shows numbers 0, 1, 2, 3, 4, 5. The y axis is labeled Distance from Ocean Surface in meters. A straight line joins the points C at ordered pair 0,63, B at ordered pair 1, 105, A at ordered pair 2, 147, and the ordered pair 3,189.

Part A: Describe how you can use similar triangles to explain why the slope of the graph between points A and B is the same as the slope of the graph between points A and C. (4 points)

Part B: What are the initial value and slope of the graph, and what do they represent? (6 points)

Answer: Part A:

A linear graph is one with a line that has the same slope all the way through. In this case, you can tell the line doesn't have the same slope the whole way through because at one part it flattens and also decreases.


Part B:

Increasing would mean the slope of the line is positive, or it appears to be going upwards. Constant would be the slope is 0, and it's just a horizontal line. Decreasing would be the slope of the line is negative, and it appears to be going downwards. In this case, this would mean that the segment K is increasing, because it appears to be going upwards, L would be constant, because it is a horizontal line, and M would be decreasing, because it's going downwards.


Part C: 

I would say the ant started moving away from the hole for 2 seconds, and then stopped for 3 seconds, and then started moving again back to the hole for another 3 seconds.

Break apart the addends to find the sum 18+21
ololo11 [35]
We break apart the first numer:

10+8

the second:

20+1

and add like this:

18+21=10+8    +  20+1

now, we can mix up the order:

18+21=10+8    +  20+1= 10+20     + 8+1

add the parts:

18+21=10+8    +  20+1= 10+20     + 8+1=30+9=39

f a sampling distribution is created using samples of the amounts of weight lost by 51 people on this diet, what would be the st
galina1969 [7]

This question is incomplete, the complete question is;

A study on the latest fad diet claimed that the amounts of weight lost by all people on this diet had a mean of 24.6 pounds and a standard deviation of 8.0 pounds.

Step 2 of 2 : If a sampling distribution is created using samples of the amounts of weight lost by 51 people on this diet, what would be the standard deviation of the sampling distribution of sample means? Round to two decimal places, if necessary.

Answer:

the standard deviation of the sampling distribution of sample means is 1.12

Step-by-step explanation:

Given the data in the question,

population mean; μ = 24.6  pounds

Population standard deviation; σ = 8.0 pounds

sample size; n = 51

Now determine the standard deviation of the sampling distribution of sample means.

standard deviation of the sampling distribution of sample means is simply

⇒ population standard deviation / √sample size

= 8.0 / √51

= 8.0 / 7.141428

= 1.120224 ≈ 1.12

Therefore, the standard deviation of the sampling distribution of sample means is 1.12
