1.A study was created to test the effects of jazz on people's sleep patterns. The hypothesis of the experiment was

that if people listened to jazz music as they fall asleep, they will sleep for longer periods of time. For the experiment,

2 groups of people were created. Group I was placed in a quiet room where they went to sleep and they were timed

on how long they slept. The Group 2 was placed in a room where jazz music played softly as they began to sleep and

played throughout the night. As each group awoke, their sleep times were monitored.

Step-by-step explanation:

The independent variable is the one which is not altered by any outer influence. For example the jazz music will not be interrupted by the sleeping habits of people.

The dependent variable is the one which is affected by external changes such as sleeping time is afffected by external music or noises.

Experimental group on which experiment is being carried out.

Control group is which determines the changes in experimental group.

Constants which do not change for the number of experiment, could be number of people, type of jazz music, volume of jazz music also sleep is a constant .

A family is comparing different car seats. One car seat is designed for a child up to and including 35 lb. Another car seat is designed for a child between 18 lb and 40

ib. A third car seat is designed for a child between 35 lb and 75 lb, inclusive. Model those ranges with compound inequalities.

Answers

Answer:

0 ≤ A ≤ 35 lb, 18 lb < B < 40 lb, 35 lb < C ≤ 75 lb

Step-by-step explanation:

Let the first car seat be A, the second car seat be B and the third car seat be C.  

For the first car seat be A, the weight ranges from 0 to 35 lb inclusive. Since it is inclusive, we use the ≤ sign. So, the inequality is

0 ≤ A ≤ 35 lb

For the second car seat be B, the weight ranges from between 18 to 40 lb. Since it is between 18 lb and 40 lb, we use the inequality sign <. So, the inequality is

18 lb < B < 40 lb

For the third car seat be C, the weight ranges from between 35 to 75 lb inclusive. Since it is between 35 lb and 75 lb inclusive, we use the inequality sign < for the left side and ≤ for the right side. So, the inequality is

35 lb < C ≤ 75 lb.

So, the ranges are

0 ≤ A ≤ 35 lb, 18 lb < B < 40 lb, 35 lb < C ≤ 75 lb

Answers

Answer:

x=2/3

Step-by-step explanation:

hope this helps :)

The solution to the equation is x = 2/3.

We have,

To solve the equation x - 5(x - 1) = x - (2x - 3), follow these steps:

- Distribute the -5 to the terms inside the parentheses:

x - 5x + 5 = x - 2x + 3

- Simplify the terms on both sides of the equation:

-4x + 5 = -x + 3

- Add -x from both sides of the equation:

-4x + x + 5 = -x + 3 + x

-3x + 5 = 3

-3x = 3 - 5

-3x = -2

x = 2/3

Therefore,

The solution to the equation is x = 2/3.

The x-intercept shows that you can buy short-sleeve shirts and long-sleeve shirts. The y-intercept shows that you can buy long-sleeve shirts and short-sleeve shirts.

Answers

Question:

You are ordering short-sleeve shirts (x) for $10 and long-sleeve shirts (y) for $15. Your budget is $300. Write the equation and find the intercepts.

Interpret their meaning.

Answer:

The x-intercept shows that you can buy 30 short-sleeve shirts and 0 long-sleeve shirts.

The y-intercept shows that you can buy 20 long-sleeve shirts and 0 short-sleeve shirts.

Step-by-step explanation:

Given

$10 per short sleeve

$15 per long sleeve

Budget = $300

The above can be represented as:

Total Cost of Short Sleeve + Total Cost of Long Sleeve = Budget

i.e.

[tex]10 * x + 15 * y =300[/tex]

[tex]10x + 15y =300[/tex]

To solve for the y intercept, we set x to 0

[tex]10 * 0 + 15y =300[/tex]

[tex]15y =300[/tex]

Divide through by 15

[tex]y = 20[/tex]

This implies that, you can buy 0 short sleeves and 20 long sleeves

To solve for the x intercept, we set y to 0

[tex]10x + 15 * 0 = 300[/tex]

[tex]10x = 300[/tex]

Divide through by 10

[tex]x = 30[/tex]

This implies that, you can buy 0 long sleeves and 30 short sleeves

Question 2 answer: The value of the angles is 76.

Question 3 answer: The value of the angle is 36.

Question 4 answer: all angles in the figures are classified as acute angles

Step-by-step explanation:

First all of, using one of the triangle rules, both the angles are congruent. Then, because both 1 and 2 are the same and the triangle in 1 already have the other two angles, use 180 - 85 - 19 and get 76. Lastly moving on to the other triangle, same method, 180 - 76 -68 and get 36. Because all these angles are less than 90 degrees and anything less than 90 is considered to be acute.

John and gary are playing a game. john spins a spinner numbered with integers from 1 to 20. gary then writes a list of all of the positive factors of the number spun except for the number itself. gary then creates a new spinner with all of the numbers on his list. john then spins this spinner, and the process continues. the game is over when the spinner has no numbers on it. if john spins a 20 on his first spin, what is the maximum number of total spins (including the one he already made) that john can make before the game is over?

Answers

Answer:

4

Step-by-step explanation:

So let's say he gets a result of 20 from the first spin. This means that the factors of 20 would be:

1, 2, 4, 5 and 10. Since 20 is not taken into account when building the next spinner.

now, the possibilities for each of the given factors are:

1:  1

2: 1, 2

4: 1, 2, 4

5: 1, 5

10: 1, 2, 5, 10

So let's take the one with the biggest amount of possible factors, in this case it would be the 10. So let's say that on the second spin, he gets a 10.

So our possible factors for 10 would be:

1, 2, 5  since we don't take 10 itself into account.

So let's see the possible factors for 1, 2 and 5

1: 1

2: 1, 2

5: 1, 5

For the third spin, you could either get a 2 or a 5, it doesn't matter which result you get since for theh last spinner, it would only have a result of 1.

so for the fourth spin, you would get a 1 as an answer and the game ends there with a total of four spins.

Answer:

4

Step-by-step explanation:

If John spins a 20, then Gary's list contains the numbers 1, 2, 4, 5, 10. Thus, these are the numbers on the second spinner.

If John spins a 1, then Gary's list will be empty because there are no positive factors of 1 besides itself. Thus, the game will be over. This yields a maximum of 1 additional spin.

If John spins a 2, then Gary's list will only contain the number 1. Then on John's next spin, we will have the same scenario as above. This yields a maximum of 2 additional spins.

If John spins a 4, then Gary's list will contain the numbers 1 and 2. As we have already found above, spinning a 2 yields more additional spins than a 1, so the maximum additional spins in this case is 3 spins.

If John spins a 5, then Gary's list will only contain the number 1. As above, this will yield a maximum of 2 additional spins.

Finally, if John spins a 10, then Gary's list will contain the numbers 1, 2, and 5. Of these numbers, 2 and 5 have the highest maximum number of additional spins, so this case has a maximum of 3 additional spins.

Thus, of all of the possibilities, spinning a 4 or 10 next could result in 3 additional spins, so the maximum total number of spins is [tex]$\boxed{4}$[/tex]. These would be achieved by spinning 20, 10, 2, 1 or 20, 10, 5, 1 or 20, 4, 2, 1.

Answers

Step-by-step explanation:

D.

subtracting the smallest value of the lower half of the data set from the biggest value of the lowest half of the data set

The lower quartile of a set of data is calculated by subtracting the smallest value of the lower half of the data set from the biggest value of the lowest half of the data set.

What is a quartile ?

"A quartile is a statistical term that describes a division of observations into four defined intervals based on the values of the data and how they compare to the entire set of observations.

Just like the median divides the data into half so that 50% of the measurement lies below the median and 50% lies above it, the quartile breaks down the data into quarters so that 25% of the measurements are less than the lower quartile, 50% are less than the median, and 75% are less than the upper quartile."

From the definition it is clear that,

lower quartile of a set of data is calculated by :

subtracting the smallest value of the lower half of the data set from the biggest value of the lowest half of the data set.

Hence, D is the correct option.
