Read the section "September 12 – The Battle of North Point."
''September 12 – The Battle of North Point
The British land and Ross boasts he will eat supper in Baltimore. Within two hours, Ross is fatally wounded by an American rifleman. Nevertheless, the British force the Americans to retreat.''
Which of the following words MOST closely matches the meaning of "retreat"?
A

Answer:
D
Step-by-step explanation:
The military term most often used for retreat is withdraw. It means that some advanced position, the battle cannot be won or turned around. So you withdraw from the field.
A: advance. No you are doing the exact opposite of retreat.
B: attack. Same as A. You are leaving the field with retreat.
C: Surrender is an entirely different thing. It means that you have given up the field and are not willing to fight anymore.
D: answer

When is it better to use Synthetic division and when is it better to use long division?
Answer:
Step-by-step explanation:
Synthetic division is a shorthand method of dividing polynomials for the special case of dividing by a linear factor whose leading coefficient is 1.
What you can do with synthetic division you can do with regular long division .But not the opposite
sin 0 =(8)/(9), tan 0 >0
find sec 0
Answer:
[tex]\displaystyle \sec(\theta)=\frac{9\sqrt{17}}{17}[/tex]
Step-by-step explanation:
We are given that:
[tex]\displaystyle \sin(\theta)=\frac{8}{9}\text{ and } \tan(\theta)>0[/tex]
And we want to find sec(θ).
First, note that both sine and tangent are positive. The only quadrant in which this can occur is QI. Hence, all trig ratios will be positive.
Also, recall that sine is the ratio of the opposite side to the hypotenuse. Using this information and the Pythagorean Theorem, we can determine the adjacent side:
[tex]a=\sqrt{9^2-8^2}=\sqrt{17}[/tex]
So, with respect to θ, the adjacent side is √(17), the opposite side is 8, and the hypotenuse is 9.
Secant is the ratio of the hypotenuse to the adjacent. Hence:
[tex]\displaystyle \sec(\theta)=\frac{9}{\sqrt{17}}=\frac{9\sqrt{17}}{17}[/tex]
Again, since θ is in QI, all trig ratios are positive.
Jasper's parents keep a chart on the wall where they mark how much Jasper grows each year. When Jasper was 15, he grew 1/10 of an inch and when he was 16, he grew 3/10 of an inch. In total, how much did Jasper grow in during those two years?
Write your answer as a fraction or as a whole or mixed number.
Answer:
In order to find the total inches Jasper grew during the two years, we have to add up the total inches he grew when he was 15 and the total inches he grew when he was 16. Therefore, we have to add 1/10 and 3/10 together.
1/10 + 3/10 = 4/10, or 2/5.
Therefore, Jasper grew a total of 2/5 inches in those two years.

∑(-1/2)^K
k=0
1. There are ____ terms.
2. The sign of each term in the series ___.
3. What is the last term in this series?
Answer:
Use the attachment below.
Step-by-step explanation:
There will be 5 terms, there will be an alternative sign of the series and their last term will be 1/16.
What is a series?A sequence's series is the total number of terms in the sequence.
A series follows some pattern for example if you take data set of natural numbers then there will be a sequence of that data and something will be due to that we can form that series.
Given that the series
∑(-1/2)^K and this summation goes from k =0 to k = 4
Now the question is asking how many terms are in there, the sign of each term in the series, and the last term in this series.
Now if you take k =0 and find the first term then it will be
(-1/2)⁰ = 1 so the first term will be 1.
Similarly, you can put k =1,2,3,4 so there will be a total of 5 terms.
The sign of each term will be alternative since because of negative somethings power will be positive if power is odd and negative if power is even.
In the last term put k = 4, and you will get (-1/2)⁴ = 1/16.

One criticism of reading comprehension tests is that while they may measure reading comprehension, they also measure other factors not related to reading comprehension. A reading comprehension (RC) test on a major college entrance exam provides short English prose passages, and the examinees answer a set of multiple-choice items about the passage. To see if particular items measure something other than RC, investigators gave the RC test without the reading passages to a random sample of psychology students. The investigators reasoned that if questions were measuring knowledge or memory rather than just RC, students would answer questions at a higher rate than chance (20%, since there were 5 choices for each question).
Suppose that on one question, 30 out of 100 examinees answered the question correctly. Is this sufficient evidence that students are using more than just reading comprehension to answer this question? Test the relevant hypothesis using alpha = .05
Answer:
The p-value of the test is 0.0062 < 0.05, which means that this is sufficient evidence that students are using more than just reading comprehension to answer this question
Step-by-step explanation:
The investigators reasoned that if questions were measuring knowledge or memory rather than just RC, students would answer questions at a higher rate than chance (20%, since there were 5 choices for each question).
This means that at the null hypothesis, we test that the proportion is the probability of answering correctly by change, that is 20%. So
[tex]H_0: p = 0.2[/tex]
At the alternate hypothesis, we test that the proportion is above 20%, that is:
[tex]H_a: p > 0.2[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
0.2 is tested at the null hypothesis:
This means that [tex]\mu = 0.2, \sigma = \sqrt{0.2*0.8} = 0.4[/tex]
Suppose that on one question, 30 out of 100 examinees answered the question correctly.
This means that [tex]n = 100, X = \frac{30}{100} = 0.3[/tex]
Test statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{0.3 - 0.2}{\frac{0.4}{\sqrt{100}}}[/tex]
[tex]z = 2.5[/tex]
P-value of the test and decision:
The p-value of the test is the probability of finding a sample proportion above 0.3, which is 1 subtracted by the p-value of z = 2.5.
Looking at the z-table, z = 2.5 has a p-value of 0.9938
1 - 0.9938 = 0.0062
The p-value of the test is 0.0062 < 0.05, which means that this is sufficient evidence that students are using more than just reading comprehension to answer this question
