The interest rate is B. 4%
Given:
Principal = 450
Interest = 126
term = 7
rate = ?
Simple Interest is computed by multiplying the Principal, rate, and term.
Interest = P × r × t
126 = 450 × r × 7
126 = 3150r
r = 126/3150
r = 0.04 x 100% = 4%
To check:
I = 450 × 0.04 x 7
I = 18 × 7
I = 126
Answer:
The selections are dependent.
Yes, they can be treated as independent (less than 5% of the population).
Step-by-step explanation:
Since the selections are made without replacement, each selection affects the outcome of the next selection and, therefore, the selections are dependent.
Although they are dependent, the selections can be treated as independent if the sample size is no more than 5% of the total population. In this case, the sample size is 1235 adults out of a population of 15,958,866 adults. The percentage represented by the sample is:
Thus the selections can be treated as independent for the purposes of calculations.
Answer:
Great use of desmos! But since one line doesn't touch the x- axis it would have to be +infinity. the other line does touch at (0,0) so the x would be 0. This is a question that you should ask your teacher about for sure.
Sorry I cant be more help!
23. To find out whether Chris, Mary Beth, and Allison are in agreement with each other, we just need to find out what the percentage is that we are working on and use what we know to understand if they are in agreement.
Chris says that 46.2% of the votes went to a certain candidate. A percent is the fraction of parts-to-whole represented in a decimal form. A percentage is NOT in decimal form, however. To get a percentage in decimal form, you can either divide the percentage by 100, or (my personal shortcut) just shift the decimal point over two places to the left.
46.2% = 0.462
Based on this, we can see that at least Chris and Allison are in agreement, since Allison said that 0.462 voters voted for the candidate in question.
To find out if Mary Beth stands with them, we just have to divide the amount of people who she says voted for the candidate by the amount of voters in total to get her percentage.
231 / 500 = 0.462
This matches the other two's results, so we can safely come to our conclusion.
YES, Chris, Mary Beth, and Allison are in agreement on the population of voters who voted for the candidate.
Hope that helped! =)
Whats the question point M would be in (-1,-8)
