Describe the number ofcards y and have after x weeks y=4x+2

Answers

i'm not sure what you're trying to ask but,
in 1 week, y will have 6 cards. 6=4(1)+2
in 2 weeks, y will have 10 cards. 10=4(2)+2
in 3 weeks, y will have 14 cards. 14=4(3)+2
you basically just substitute in the number of weeks with x and then just solve the problem to find out the total number of cards

Choose 1 answer
(A) -2 percentage points
(B) -1 percentage points
(C) -1/2 percentage points
(D) -1/4 percentage points

Answers

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: -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.

log (7x-10)=2

Use the identity: loga(x)=b = x=(a)(b)

7x-10=10^2

Evaluate the Power

7x-10=100

Addition Property of Equality

7x=110

Division Property of Equality

x=110/7 or 15.7143

2. Answer: 0.3107
