Answer 2

Answer:

11

Step-by-step explanation:

1/2 ( 4^2 + √25 + 1)

= 1/2 (16 + √25 + 1)

= 1/2 ( 16 + 5 + 1)

= 1/2 ( 21 + 1)

= 1/2 (22)

= 1/2 x 22/1

= 22/2

= 11/1 = 11

Answers

Answer:

Answer:

See the graph attached. The red arrow represents the shaded area.

Explanation:

The inequality and its solution are given:

     

The solution set is all real numbers less than or equal to -50.

In a number line, the values less than -50 are all the values that are to the left of -50. Thus, the graph of a ≤ -50 must include -50 and the region to the left of it.

To indicate that - 50 is included, draw a solid point; then, shade the region since it to its left.

Please, see the graph attached. The red arrow represents the shaded area.

2 horses ran from the same place from the at same time one horse ran at 2 miles per second and the other ran at a speed for 18 miles per second. how far apart were they in 1 minute? in 5 minutes? in 8 minutes?

- PLS HELP ASAP!!!!!

Answers

Answer:

1 minute = 1080 - 960 = 120 m

5 minutes = 5400 - 4800 = 600 m

8 minutes = 8640 - 7680 = 960 m

Step-by-step explanation:

I think the easiest way is to just see how far they get at each time.  So I'm going to go one horse at a time.

16 m/s

1 minute = 60 seconds, every second is 16 meters so 16 m/s * 60 s = 960 m

5 minutes = 300 seconds so 16 m/s * 300 s = 4800 m

8 minutes = 480 seconds, 16 m/s * 480 s = 7680 m

I also want to point out that unites cancel out.  m/s * s is kinda like variables so the seconds being multiplied by m/s cancels witht eh seconds in the denominator.

Now the next horse

18 m/s

1 minute totals to 1080 m

5 minutes = 5400 m

8 minutes = 8640 m

Now we take the differences of each time

1 minute = 1080 - 960 = 120 m

5 minutes = 5400 - 4800 = 600 m

8 minutes = 8640 - 7680 = 960 m

Another way to do this is to take the difference of speed and then multiply that by the time.  so 18-16 = 2, then multiply each time by 2.  For me it just makes more intuitive sense the way I showed.

what is the mean absolute deviation of the data set below?
3,1,4,4,4,1,1,2,1,5

Answers

Answer:

1.4

Step-by-step explanation:

Step 1: We have to find the mean of the data set

The mean is the average or the sum of all the numbers divided by the amount of numbers there are.

3 + 1 + 4 + 4 + 4 + 1 + 1 + 2 + 1 + 5 = 26

There are 10 numbers in total so, 26/10 = 2.6

Step 2: We now know the mean so now we have to find the deviation

3 - 2.6, |1 - 2.6|, 4 - 2.6, 4 - 2.6... so on, (Note: this is just finding the distance between the numbers and the mean)

The results are, 0.4 + 1.6 + 1.4 + 1.4 + 1.4 + 1.6 + 1.6 + 0.6 + 1.6 + 2.4

This is equal to 14

Step 3: Lastly, we have to find the mean of the deviations

We know the mean is 14

We have 10 numbers

Therefore, 14/10 = 1.4 is the MAD

1/4 is the answer I think
