Answer:
B:0
Step-by-step explanation:
This question tests your understanding of the rules of logarithms. You only need to look at the first term to get the answer. The crucial rule here is that:
[tex]log_b(1)=0[/tex]
for ANY base b. And since anything multiplied by 0 is 0, that gives you your answer.

(c) Suppose that 20% of voters are in favor of certain legislation. A large number n of voters are polled and a relative frequency estimate fA(n) for the above proportion is obtained. Use central limit theorem to estimate how many voters should be polled in order that the probability is at least .95 that fA(n) differs from 0.20 by less than 0.02
Answers
Answer:
1537 voters should be polled.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
20% of voters are in favor of certain legislation.
This means that [tex]\pi = 0.2[/tex]
How many voters should be polled in order that the probability is at least .95 that fA(n) differs from 0.20 by less than 0.02
This is n for which M = 0.02. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.02 = 1.96\sqrt{\frac{0.2*0.8}{n}}[/tex]
[tex]0.02\sqrt{n} = 1.96\sqrt{0.2*0.98}[/tex]
[tex]\sqrt{n} = \frac{1.96\sqrt{0.2*0.98}}{0.02}[/tex]
[tex](\sqrt{n})^2 = (\frac{1.96\sqrt{0.2*0.98}}{0.02})^2[/tex]
[tex]n = 1536.6[/tex]
Rounding up
1537 voters should be polled.

Sue has $100 saved to buy concert tickets that go on sale in 8 weeks. She plans to save $15 every 2 weeks. Will Sue have enough money saved to buy 4 concert tickets that cost $50 each?
Answers
Answer:
she wont have enough money.
Step-by-step explanation:
she is saving money every 2 weeks. 8 divided by 2 is 4, so we'd have 15 x 4 which is 60. then we'd add it to 100, which would be 160, then divide it by 4, which would roughly come down to 40 dollars each, meaning we would not have enough money for 4 tickets
Answer:
she does not have enough she will need 40 dollars more

(7.RP.3)
Answers
Answer:
Step-by-step explanation:
%change=100(final-initial)/(initial)
final=20-12=8 and initial=20 so

Anything times zero is zero, so any whole number can be the second one so long as the first is 0.

The diameters of bolts produced in a machine shop are normally distributed with a mean of 6.4 millimeters and a standard deviation of 0.06 millimeters. Find the two diameters that separate the top 5% and the bottom 5%. These diameters could serve as limits used to identify which bolts should be rejected. Round your answer to the nearest hundredth, if necessary.
Answers
Answer:
The bolts with diameter less than 5.57 millimeters and with diameter greater than 5.85 millimeters should be rejected.
Step-by-step explanation:
We have been given that the diameters of bolts produced in a machine shop are normally distributed with a mean of 5.71 millimeters and a standard deviation of 0.08 millimeters.
Let us find the sample score that corresponds to z-score of bottom 4%.
From normal distribution table we got z-score corresponding to bottom 4% is -1.75 and z-score corresponding to top 4% or data above 96% is 1.75.
Upon substituting these values in z-score formula we will get our sample scores (x) as:
Therefore, the bolts with diameters less than 5.57 millimeters should be rejected.
Now let us find sample score corresponding to z-score of 1.75 as upper limit.
Therefore, the bolts with diameters greater than 5.85 millimeters should be rejected
