Sheldon Cooper is interested in studying the effect of distance from the bathroom mirror and the number of droplets of toothpaste that splatter on the mirror during tooth brushing. To conduct his study, he brushes his teeth at various distances from the mirror a total of 100 times. What is the sample of this study?

Answers

Answer 1

Answer:

the sample = the 100 times Sheldon brushed his teeth in front of the mirror

Step-by-step explanation:

In statistics, the sample is a small portion of a population that a researcher can study. It should represent a random subset of data from the population. The advantage of using a sample is that the size is smaller than the whole population, which makes it more manageable.

When you study the whole population, you are performing a census. That means that you are not obtaining a sample. In this case, the population would be every time that Sheldon or someone else washes his/he teeth in that bathroom.

change g(x) to y and switch x and y. from here you need to solve for y. first you get rid of the fraction by multiplying both sides by 5. you now have 5x=9y+25. to isolate y, subtract 25 from both sides 5x-25=9y. last divide both sides by 9: 5/9x -25/9 = y

Step-by-step explanation:

Answer:

x = 55, upper left angle is 135, down left angle is 55

Step-by-step explanation:

The shape is a quadrilateral and all of the quadrilaterals angles added together is 360 degrees and that little square at the bottom right of the shape means it's a right angle and a right angle is 90 degrees so:

4x - 85 + 80 + x + 90 = 360

rearrange to make it easier to add like terms

4x + x - 85 + 80 - 90 = 360

add like terms

5x + 85 = 360

subtract 85 from both sides

5x = 275

divide both sides by 5

x = 55

Plug 55 into 4x - 85 to find the angles

4(55) - 85 = 135

Jeremy’s house is 45 feet wide. In a photograph the width of the house was 2.5 inches, and its height was 2 inches. What is the actual height of Jeremy’s house?

Answers

Hello!

[tex]\large\boxed{36 ft}[/tex]

We can use proportions to solve for the actual height of his house. Remember, we must convert from inches to feet:

1 foot = 12 inches

45 ×12 = 540 inches

Set up a proportion:

[tex]\frac{2.5}{540} = \frac{2}{x}[/tex]

Cross multiply:

2.5 · x = 540 · 2

2.5x = 1080

Divide both sides by 2.5:

x = 432 inches

Convert back to feet:

432 / 12 = 36 feet
