The vibration in a plucked guitar string travels at a speed of 410 meters per second. How far, in centimeters will the vibration travel in 0.40 milliseconds? Note: There are 100 centimeters in one meter and 1000 milliseconds in one second.
Answer:
16.4 cm/0.4 ms
Explanation:
1: We know that the travel rate is 410 meters per second. We want to find a way in which we can cancel meters or seconds, and we can do that by multiplying 410m/1s with 100 cm/1m.
\(\frac{410 m}{1s} * \frac{100cm}{1m}\)
2. Now we want to get rid of that s, seconds, and we do so by multiplying prior fractions by 1s/1000ms.
\(\frac{410 m}{1s} * \frac{100cm}{1m} * \frac{1s}{1000ms} \\\)
3. Now we can diagnollay cross out m, and s. Leaving us with cm on top, and ms on the bottom. Which is what we want because we are calculating how many cm are for every .04 ms.
4: After that, you can multiply 410 and 100, to get 4,100. Whih leaves you with 4,100cm over 1000ms. Simplifying this, gives you 41, but that is NOT your answer. 41 cm, is for every ms, NOT every .04
5. Hence, you multiply 41 by .04 and get 16.4cm/.04ms.

Given that from an inventory of 48 new cars being shipped to local dealerships, corporate reports indicate that 12 have defective radios installed. Here, p denotes the probability of success and q denotes the probability of failure such that p + q = 1. For the given problem p=12/48=1/4, and q=1−p=3/4. Therefore,
1. The probability out of the 8 new cars it just received that when each is tested, no more than 2 of the cars have defective radios is as follows:This is a binomial probability question where n = 8, x = 0, 1 or 2.So, P(X ≤ 2) = P(X=0) + P(X=1) + P(X=2)This is calculated as follows: P(X=0) = C(8, 0) (1/4)^0 (3/4)^8 = 0.1001P(X=1) = C(8, 1) (1/4)^1 (3/4)^7 = 0.3004P(X=2) = C(8, 2) (1/4)^2 (3/4)^6 = 0.3299Therefore, P(X ≤ 2) = 0.1001 + 0.3004 + 0.3299 = 0.7304Thus, the probability is 0.7304.
2. The probability out of the 8 new cars it just received that when each is tested, exactly half of the cars have defective radios is as follows:This is a binomial probability question where n = 8, x = 4.So, P(X = 4) = C(8, 4) (1/4)^4 (3/4)^4 = 0.0865Thus, the probability is 0.0865.3.
3. The probability out of the 8 new cars it just received that when each is tested, none of the cars have defective radios is as follows:This is a binomial probability question where n = 8, x = 0.So, P(X = 0) = C(8, 0) (1/4)^0 (3/4)^8 = 0.1001Thus, the probability is 0.1001.4.
4. The probability out of the 8 new cars it just received that when each is tested, no more than 2 of the cars have defective radios is as follows:This is a binomial probability question where n = 8, x = 0, 1 or 2.So, P(X ≤ 2) = P(X=0) + P(X=1) + P(X=2)This is calculated as follows: P(X=0) = C(8, 0) (1/4)^0 (3/4)^8 = 0.1001P(X=1) = C(8, 1) (1/4)^1 (3/4)^7 = 0.3004P(X=2) = C(8, 2) (1/4)^2 (3/4)^6 = 0.3299Therefore, P(X ≤ 2) = 0.1001 + 0.3004 + 0.3299 = 0.7304Thus, the probability is 0.7304.

As Ruchira is packing her apartment while preparing to move in with her new husband, Biren, she reflects
on the first time he saw her artwork.
(1) He'd moved close to the wall and was standing very still. (2) It took her a moment to figure out that he
was examining her brushstrokes. (3) (But only artists did that. (4) Was he a closet artist, too?) (5) Finally he
moved back and let out a long, incredulous breath, and it struck her that she had been holding hers as
well. (6) "Tell me about your work," he said.
(7) This was hard. (8) She had started painting two years ago, and had never talked to anyone about it. (9)
Even her parents didn't know. (10) When they came for dinner, she removed the canvases from the wall
and hid them in her closet. (11) She sprayed the room with Eucalyptus Mist and lit incense sticks so they
wouldn't smell the turpentine. (12) The act of painting was the first really risky thing she had done in her
life. (13) Being at the gallery, she knew how different her work was from everything in there, or in the
glossy art journals. (14) Her technique was crude-she hadn't taken classes and didn't intend to. (15) She
would probably never amount to much. (16) Still, she came back from work every evening and painted
furiously. (17) She worked late into the night, light-headed with the effort to remember. (18) She stopped
inviting people over. (19) She made excuses when her friends wanted her to go out. (20) She had to force
herself to return their calls, and often she didn't. (21) She ruined canvas after canvas, slashed them in
frustration and threw them into the Dumpster behind the building. (22) She wept till she sa a blurry
brightness, like sunspots, wherever she looked. (23) Then, miraculously, she got better. (24) Sometimes
now, at 2:00 or 3:00, her back muscles tight and burning, a stillness would rise around her, warm and

The probability that the space shuttle is launched on the designated day is 80%. Assume that
shuttle launches are independent from each other. Suppose four launches are scheduled in the
next three months. What is the probability that more than one is launched on the designated
day?
Answer:
0.9728
Explanation:
P(launch), p = 80% = 0.8
(1 - p) = 1 - 0.80 = 0.2
Number of launches = 4
We can apply the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - r)
Probability that More than 1 is launched
P(x > 1) = p(x = 2) + p(x = 3) + p(x = 4)
P(x = 2) :
4C2 * 0.8^2 * 0.2^2
6 * 0.64 * 0.04 = 0.1536
P(x = 3) :
4C3 * 0.8^3 * 0.2^1
4 * 0.512 * 0.2 = 0.4096
P(x = 4) :
4C4 * 0.8^4 * 0.2^0
1 * 0.4096 * 1 = 0.4096
P(x > 1) = 0.1536 + 0.4096 + 0.4096
P(x > 1) = 0.9728
10. A researcher is interested in estimating the mean alcohol content for a particular brand of cough medicine. They randomly sample 50 bottles of this brand and find a sample mean of 8.6 (percent alcohol). Let u denote the mean alcohol content (in percent) for the population of all bottles of the brand under study. The population standard deviation is 2.2. a.) Construct a 95% confidence interval for u
Answer:
To construct a 95% confidence interval for the mean alcohol content of the population of all bottles of the brand under study, you can use the following formula:
Sample mean +/- (t-value * standard error)
The t-value can be found using a t-distribution table or a computer program. It is based on the desired confidence level (in this case, 95%) and the degrees of freedom, which is the sample size minus 1 (in this case, 50-1=49).
The standard error is calculated as:
Standard error = population standard deviation / sqrt(sample size)
Plugging in the given values, you get:
Standard error = 2.2 / sqrt(50) = 0.22
Using a t-distribution table or computer program, you can find that the t-value for a 95% confidence interval with 49 degrees of freedom is 2.01.
Therefore, the 95% confidence interval for the mean alcohol content of the population of all bottles of the brand under study is:
8.6 +/- (2.01 * 0.22)
Which simplifies to:
8.6 +/- 0.44
So the 95% confidence interval for the mean alcohol content of the population is (8.16, 8.94).
The mean diastolic blood pressure for a random sample of 80 people was 82 millimeters of mercury. If the standard deviation of individual blood pressure readings is known to be 12 millimeters of mercury, find a 99% confidence interval for the true mean diastolic blood pressure of all people. Then give its lower limit and upper limit.
Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place.
The 99% confidence interval for the true mean diastolic blood pressure of all people is approximately (73.4, 90.6) and The lower limit is 73.4 millimeters of mercury, and the upper limit is 90.6 millimeters of mercury.
To calculate the 99% confidence interval for the true mean diastolic blood pressure of all people, we can use the formula:
Confidence Interval = Sample Mean ± (Critical Value) * (Standard Deviation / √(Sample Size))
Given that the sample size is 80, the sample mean is 82, and the standard deviation is 12, we need to find the critical value corresponding to a 99% confidence level.
Since the sample size is large (n > 30) and the population standard deviation is known, we can use the Z-distribution. The critical value for a 99% confidence level (α = 0.01) is approximately 2.576.
Plugging in the values into the formula, we get:
Confidence Interval = 82 ± (2.576) * (12 / √80)
Calculating the values:
Confidence Interval = 82 ± (2.576) * (12 / √80)
≈ 82 ± (2.576) * (12 / 3.577)
≈ 82 ± (2.576) * 3.358
≈ 82 ± 8.647
Rounding to one decimal place:
Lower Limit = 82 - 8.647 ≈ 73.4
Upper Limit = 82 + 8.647 ≈ 90.6

circulating?
A) Banks will give out more loans.
B) The unemployment rate will go up.
C) Prices will go up.
D) Businesses will be able to hire more employees.
A number of reasons can contribute to deflation, such as a lack of money in circulation, which raises the value of that money and lowers prices, and an excess of supply relative to demand, which forces businesses to lower their prices to attract customers. Thus, option B is correct.
What is the role of credit circulating in the economy?Inflation occurs as a result of price increases that happen too quickly. People do not have surplus disposable income, and there is no economic growth if there is too little money in the economy.
Borrowing costs are frequently the result of more money being available, which encourages higher investment and more money in the hands of consumers, both of which promote consumption.
Businesses react by placing additional orders for raw materials and raising production levels.
Therefore, unemployment rate will go up, to the economy when there's too little money or credit circulating.
