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.

The equation that models the height above or below equilibrium in inches, h, of a spring over time in seconds, t, is h = -15 cos(2pi/5 t). At which times will the spring be at a height of 8 in. above equilibrium? Select two of the following, make two selections.

Answers

Answer:

1.7 seconds, and

3.3 seconds

Step-by-step explanation:

We simply need to plug in 8 into h and solve for t:

h=-15Cos((2\pi)/(5)t)\n8=-15Cos((2\pi)/(5)t)\n-(8)/(15)=Cos((2\pi)/(5)t)\n(2\pi)/(5)t=Cos^(-1)(-(8)/(15))\n(2\pi)/(5)t=2.13\nt=(2.13)/((2\pi)/(5))\nt=1.70

Since cosine is negative in the 3rd quadrant as well, we need to figure out the 3rd quadrant equivalent of 2.13 radians.

First, π - 2.13 radians = 1.01 radians.

Then, we add 1.01 to π radians, so we get 4.15 radians

Solving from the last part, we have:

t=(4.15)/((2\pi)/(5))\nt=3.3

also, t = 3.30 seconds

*Note: we put the calculator mode in radians when solving

So, t = 1.7 seconds & 3.30 seconds

What is the distance between the two numbers on the number line?-7/4, 3/8

-2 1/8
-1 3/8
1 3/8
2 1/8

Answers

Answer: - 2 1/8

Step-by-step explanation: Lets first get common denominators of 8.

-7/4 = -14/8             (-7 x 2 = -14 and 4 x 2 = 8)

-14/8 - 3/8 = -17/8 or -2 1/8

Answer:

2 1/8.

Step-by-step explanation:

That is  |-7/4| + 3/8

= 7/4 + 3/8

= `14/8 + 3/8

= 17/8

= 2 1/8.
