1.A nutritionist wants to collect data on how much caffeine the average American drinks per day. She has the following ideas for how she could obtain a sample:



1.Ask the first 20 adults who arrive at a grocery store after 10:00 a.m. about the average amount of caffeine they consume each day.
2.Every 30 minutes, ask the first adult who comes into a coffee shop about the average amount of caffeine they consume each day.


•Would the different methods for selecting a sample lead to different conclusions about the population?
•What are the benefits of each method?
•What might each method overlook?
•Which of the methods listed would be the most likely to produce samples that are representative of the population being studied?
•Can you think of a better way to select a sample for this situation?

Answer:

B. x [tex]\leq[/tex] -3.5

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Since the dot is at 3.5, the possible options are B and F since the circle is filled in we know that the line includes this point meaning : [tex]\leq or \geq[/tex] Both of them have this, If we look at the line the line is moving decreasing therefore 3.5 is greater than the line formed. This is represented by the equation: [tex]x\leq -3.5[/tex].

The equation y = 38x + 50 models the data on a plumber's scatter plot, where x is the number of hours the plumber works, and y is the total bill in dollars. If Sal pays the plumber $126, how many hours did the plumber work?

1 hour
1.75 hours
2 hours
2.5 hours

Answers

Answer:

2 hours

Step-by-step explanation:

I substituted y for 126 and solved like so:

126 = 38x + 50

126 - 38x = 50

(126-126) - 38x = 50 - 126

-38x = -76

-38x/-38 = -76/-38

X = 2

There ya go! Hope this helps, good luck :)

The answer would be 2 hours,
y being the total ($126) so you would plug in 126 for y and solving the equation.

Answer:

b = -3

a = -0.5.

Step-by-step explanation:

As both right sides are equal to a:

12b + 3 = -2b - 4

12b + 2b = -4 - 3

14b = -7

b = -0.5.

So a = 12(-0.5) + 3 = -6 + 3

= -3.

15 15 15 15 15 15 15 15 15 15

Answer:

18

Step-by-step explanation:

So what you need to find is the scale factor which is the scale of the difference between two lengths.

So Figure A is smaller than Figure B, as can be easily detected with our eyes.

Figure A has a ratio of 1/2, as 6/12 is equal to 1/2.

Since B is the original, where A is a scaled version, it must also have the same ratio of 1/2, so twice 9 is 18, which is your answer.

You can also use fractions, by making Figure A into 1/2 because 1/2 = 6/12.

Figure B can turn into 9/x.

Since you know they are scaled factors, they have the same ratio since one is scaled larger or smaller than from the original.

Since it must follow the multiplication of 2 for the side length, 9 x 2 gives your answer.
