Math Twelve hundred students participated in the school chemistry contest. A random sample (Sample 1) from grades 9 and 10 showed scores of: 84, 50, 99, 83, 50, 78, 88, 85, 77, and 96.

A random sample (Sample 2) of grades 11 and 12 showed scores of: 57, 62, 86, 82, 74, 78, 96, 90, 97, and 83.

What is Statistics?

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

A random sample (Sample 1) from grades 9 and 10 showed scores of:

84, 50, 99, 83, 50, 78, 88, 85, 77, and 96.

Ascending order: 50, 50, 77, 78, 83, 84, 85, 88, 96, 99

The sample has an even number of scores, so the median is the average of the two middle scores:

(83 + 84)/2

= 83.5

Therefore, the median of Sample 1 is 83.5.

For sample 2, the data set is 57, 62, 86, 82, 74, 78, 96, 90, 97, and 83.

Ascending order of scores: 57, 62, 74, 78, 82, 83, 86, 90, 96, 97

The sample has an even number of scores,

so the median is the average of the two middle scores: (82 + 83)/2

= 82.5

Hence, the median of Sample 1 is 83.5 and median of Sample 2 is 82.5.

Math homework help?Pooters and Dooters were walking across a bridge one day, minding their own business. They knew that a train was due to come across that bridge soon, but they thought they could make it. It was a nice sunny day, and there was a great view from the bridge, so they walked very slowly, enjoying the view and savoring the warmth of the spring day.They were one-third of the way across the bridge, when the sound of a train whistle brought them instantly back to reality. Looking back over their shoulders, they saw a huge locomotive pulling tons of boxcars coming directly at them at 24 miles per hour! Using all their powers of mathematical reasoning, Pooters and Dooters immediately figured that they could run directly ahead and get to the far edge of the bridge at the exact same instant as the train. But they also knew that they could run back toward the train and get to the near end of the bridge just as the train got there. Basically, they knew they were dead meat.How fast do Pooters and Dooters run?please help me get an equation to solve the problem.

Determine the measure of the interior angel at vertex A

Answers

The total of interior angles of a polygon is found using the formula 180 x (n-2) where n is the number of sides.

The above figure has 7 sides, so the total of the interior angles is: 180 x (7-2) = 180 x 5 = 900 degrees.

Find X:

Total all angles: 2x+4x+4x+4x+4x+2x+10x = 900

30x = 900

X = 900/30

x = 30

Angle A = 2x = 2*30 = 60 degrees

The answer is A.

C. 84*

If incorrect, my apologies.

Step-by-step explanation:

A student thinks the sum of 4.3 and 8.4 is 12.7 because 4+8 is 12 and 3+4 is 7. The student then adds 3.7 and 2.6, then gets 5.13 because 3+2 is 5 and 6+7 is 13. Identify the mistake in the students procedure and explain why the procedure won't always work.

Answers

The mistake the student made in the second procedure is she tried to solve 3.7+2.6 the same way she solved 4.3+8.4, which that way doesn't always work. You have to understand how decimals work when it comes to adding them. The right way to solve 3.7+2.6 and be sure you are accurate is to line the numbers up. Then add the numbers behind the decimal which is 7+6. That equals 13. So you would out your 3 and carry your 1 over to the number in front of the decimal. So 3+2=5, plus the additional one you had to carry. Your final answer would be 6.3
