Answer 1

Answer:

Final answer:

Though the scatter plot isn't available, interpretation of the plot would suggest an average change in smoking rate. The optimal choice can't be stated without the graph.

Explanation:

This question is asking you to interpret the trend shown in a scatter plot, which falls under the mathematical topic of statistics. Since the question does not provide a visible scatter plot, we cannot confidently select an answer choice for a change in the smoking rate. However, if a scatter plot were available, you would analyze it to find the average rate of change from year to year. Each percentage point represents the change in the percentage of adult smokers in the United States from one year to the next.

Answer 2

Answer:

Answer: -1/2 percentage points.

Step-by-step explanation:

Since the data shows a mostly linear trend, a line can be drawn to estimate the rate of change.

The line approximately goes through (0,40) and (10,35), so a approximation for the slope is 35-40/10-0, equaling -1/2.

A collection of 8 backpacks has a mean weight of 14 pounds. A different collection of 12 backpacks has a mean weight of 9 pounds. What is the mean weight of the 20 backpacks? Explain how you found your answer.

Answers

Total weight of the first 8 backpacks
8*14
112 pounds

Total weight of the second 12 backpacks
12*9
108

Total weight of the whole 20 backpacks
112+108
220

So the mean weight of the 20 backpacks
220 / 20
11

Answer: 11

Step-by-step explanation:

We know that mean of a number of observations is given by :-

$\text{Mean}=\frac{\text{Sum of all observations}}{\text{Number of observations}}\n\n\Rightarrow\ \text{Sum of all observations}=\text{Mean*Number of observations}$

Given: The mean weight of 8 backpacks = 14 pounds

$\Rightarrow\ \text{Sum of weight of 8 backpacks}=14*8=112$

The mean weight of different 12 backpacks =9 pounds

$\Rightarrow\ \text{Sum of weight of 12 backpacks}=12*9=108$

Now, Total sum of all observations = 112+108=220 pounds

Now, the mean weight of the 20 backpacks is given by :-

$\text{Mean}=(220)/(20)=11$

You and some friends went out to T.G.I.Fridays for dinner. You ordered a root beer, sweet potato fries and cheese quesadillas. The total bill came to $21.86. Your dad as told you many times that it's important to leave a good tip; about 20%. You have $27.00 in your wallet. Can you leave a 20% tip? How much would the total be if you left a 15% tip? Can you cover the cost?

Answers

$27 - $21.86 = $5.14

20% of $27 is $5.40
No, you cannot cover the cost of this.

15% of $27 is $4.05

You'd be able to afford to cover the cost with this with $1.09 left over.
