Answer: Both p and q are 8cm long.
Step-by-step explanation:
BE created a similar triangle that is exactly half of the larger triangle.
So if BE is 4 and AE is 8 then we know that CD is 8 and AD is 16.
However we only need segment q which is half of AD so the answer is:
p=8 and q=8

a(n) _____ is an obvious line where foundation starts or stops.
A seam or edge is an obvious line where the foundation starts or stops. This term refers to a clear boundary or distinction between two areas or surfaces, such as when applying makeup.
A seam or edge is an obvious line where the foundation starts or stops. These lines indicate the boundary of where foundation makeup should be applied or where it should end. It is important to blend the foundation seamlessly into the skin to avoid any noticeable lines or streaks. Additionally, applying a primer beforehand can help smooth out the skin's texture and create a more even base for foundation application. By taking the time to properly blend and apply foundation, you can achieve a flawless, natural-looking complexion.

Chaim has won $5,000 and wants to save it towards buying a house in six years when he finishes his law degree. He has the choice between an account which compounds daily (so n=365) with an APR of 7% and another which also has a 7% APR but compounds quarterly (so n=4). How much more interest will he earn if he chooses the first account? Chaim will earn $________ more by choosing the first account. (Enter an answer rounded to two decimal places.)
Answer:
Chaim will earn $3.21 more by choosing the first account.
Step-by-step explanation:
We find the Future value of the accounts
Future value formula = Present value × (1 + r/n)ⁿ
Where r = rate
n = compounding frequency
For Account 1
Compounds daily (so n=365) with an APR of 7%
Future value
= 5000 × (1 + 0.07/365)³⁶⁵
= 5000 × (1 + 0.0001917808)³⁶⁵
= $5362.504873
Interest = Future value - Present value = $(5362.504873 - 5000)
= $362.504873
Account 2
7% APR but compounds quarterly (so n=4).
Future value = 5000 × (1 + 0.07/4)⁴
= 5000 × (1 + 0.0175)⁴
= $5359.2951564
Interest = Future value - Present value
= $(5359.2951564 - 5000)
= $359.2951564
How much more interest will he earn if he chooses the first account?
Interest (first account) - Interest (second account)
= $362.504873 - $359.2951564
= $3.2097166
Approximately to 2 decimal places
= $3.21

Crownfashions.com wants to estimate the average time that visitors to its website spend browsing the site. In a random sample of 49 visits this week, average browsing time is 13.6 minutes. Assume you know the population standard deviation is 5.2 minutes. Construct an 80% confidence interval estimate of average browsing time for the population of crownfashion.com visitors this week. Report the margin of error indicated by the interval.
The 80% confidence interval estimate for the average browsing time is approximately 12.648572 minutes to 14.548572 minutes.
To construct an 80% confidence interval estimate of the average browsing time for the population of crownfashion.com visitors this week, we can use the following formula:
Confidence Interval = \(\bar{X}\) ± Z \(\times\) (σ/√n)
Where:
\(\bar{X}\) is the sample mean (average browsing time) = 13.6 minutes,
Z is the Z-score corresponding to the desired confidence level (80% confidence level corresponds to a Z-score of 1.28),
σ is the population standard deviation = 5.2 minutes,
n is the sample size = 49.
Plugging in these values, we can calculate the confidence interval as follows:
Confidence Interval = 13.6 ± 1.28 \(\times\) (5.2/√49)
Simplifying the expression:
Confidence Interval = 13.6 ± 1.28 \(\times\) (5.2/7)
Confidence Interval = 13.6 ± 1.28 \(\times\) 0.742857
Confidence Interval = 13.6 ± 0.951428
The lower bound of the confidence interval is 13.6 - 0.951428 = 12.648572, and the upper bound is 13.6 + 0.951428 = 14.548572.
Therefore, the 80% confidence interval estimate for the average browsing time is approximately 12.648572 minutes to 14.548572 minutes.
The margin of error indicated by the interval is half of the width of the confidence interval, which is (14.548572 - 12.648572) / 2 = 0.95 minutes.

A tree 18 meter high is broken off 3 meter from the ground . how far from the foot of the tree will the top strike the ground ?
Answer:
Therefore, the top of the tree will strike the ground about 17.75 meters away from the foot of the tree.
Step-by-step explanation:
We can solve this problem using the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. In this case, the tree trunk and the ground form one leg of the triangle, and the broken off portion of the tree forms the other leg, while the distance the top of the tree falls is the hypotenuse.
Let's call the distance we want to find "x". Then, we can set up the following equation:
x^2 = 18^2 - 3^2
where 18 is the height of the tree, and 3 is the distance from the ground where the tree is broken.
Simplifying the right-hand side of the equation, we get:
x^2 = 315
Taking the square root of both sides, we get:
x = sqrt(315) ≈ 17.75

jill counted 20 pigs and chickens in the farmyard. jack counted a total of 54 legs for the 20 animals. how many pigs and how many chickens were there?
As average animal has four legs, there were ten pigs and ten chickens, giving a total of 54 legs: 10 x 4 = 40 legs, 10 x 2 = 20 legs.
10 pigs and 10 chickens were present. 10 pigs have 4 legs each, for a total of 40 legs. 10 chickens have 2 legs each, for a total of 20 legs. 40 + 20 = 54 legs. Jill counted the animals in the farmyard and found twenty. The 20 animals had a total of 54 legs, according to Jack. We can perform a straightforward step-by-step computation to determine the number of pigs and chicks present. Since each pig has four legs, we may generate 40 legs by multiplying the number of pigs, 10, by 4. Similar to humans, chickens have two legs each, so multiplying 10 by 2 results in 20 legs. The sum of the two figures gives us 54 legs, which is the same as Jack's estimate. Hence, the farmyard contained 10 pigs and 10 hens.

______ as a type of sales promotion is beneficial because they can encourage consumers to try out a product at reduced risk, but they can be detrimental because they reduce perception of value for the product or service.
Free samples or product trials as a type of sales promotion can be both beneficial and detrimental. They encourage consumers to try a product at reduced risk, but they can also reduce the perception of value for the product or service.
Offering free samples or product trials is a common sales promotion strategy to attract customers and encourage them to try a product or service. This approach has several benefits. Firstly, it lowers the perceived risk for consumers as they can experience the product without making a financial commitment upfront. This can be especially effective for new or unfamiliar products, as it allows potential customers to test the product's quality and functionality.
However, there can be drawbacks to this sales promotion technique. Providing free samples or trials can create the perception that the product or service has less value or is of lower quality. Consumers may develop a mindset of expecting free or discounted offerings, and it can undermine the willingness to pay the full price in the future. Additionally, if the free samples or trials are not managed effectively, it may attract individuals who are not genuinely interested in the product, leading to wastage of resources and potentially diluting the brand image.

Answer:
The correct answer is D.
Step-by-step explanation:
According to the Pythagorean Theorem, the legs of a right triangle squared and added together is equivalent to the hypotenuse squared. To solve for x, you can use any of the two right triangles. Each of the bottom legs of the right triangles is 9 units since the two right triangles are congruent, so now we apply the Pythagorean Theorem to solve for x. \(x^2+9^2=19^2\) ⇒ \(x^2+81 = 361\) ⇒ \(x^2 = 280\) ⇒ \(x = \sqrt{280}\) ⇒ \(x = \sqrt{4 * 70}\) ⇒ \(x = \sqrt{4} * \sqrt{70}\) ⇒ \(x = 2\sqrt{70}\).
The engineer in charge of the coffee manufacturing process examines the confidence intervals for the mean caffeine content calculated over the past several weeks and is concerned that the intervals are too wide to be of any practical use. That is, they are not providing a very precise estimate of μ.
a. What would happen to the width of the confidence intervals if the level of confidence of each interval is increased from 95% to 99%?
b. What would happen to the width of the confidence intervals if the number of samples per hour was increased from 50 to 100?
a) If the level of confidence of each interval is increased from 95% to 99%, the width of the confidence intervals will increase.
b. If the number of samples per hour was increased from 50 to 100, the width of the confidence intervals will decrease.
a) When the level of confidence of each interval is increased from 95% to 99%, the intervals will be wider. This is because a higher level of confidence requires a larger margin of error. The margin of error is the range within which the true population parameter is likely to fall with a given level of confidence. An increase in the level of confidence will result in a wider margin of error, hence a wider confidence interval.
b) When the number of samples per hour is increased from 50 to 100, the standard error of the mean will decrease. This is because the standard error of the mean is inversely proportional to the square root of the sample size. A larger sample size will lead to a smaller standard error of the mean, which in turn results in a narrower confidence interval.

Play play players are 3/10 of a band and the trumpet players are 1 / 12 of the band. is a greater fraction of the bands flute players or trumpet players
There are more flute players than trumpet players because the fraction of flute players in the band is greater than the fraction of trumpet players in said band.
How do you prove that?Perhaps what you meant was "Which is the greater fraction of the bands: flute players or trumpet players?"
Before we compare the fraction 3/10 and the fraction 1/12, we need to make the denominators of the given fractions the same. One way to do this is to take the least common multiple (LCM) of the denominators and multiply the numerator and denominator of each fraction by certain numbers so that the denominators equal to the LCM.
The LCM of the denominators is 60. 60 divided by 10 is equal to 6, and 60 divided by 12 is equal to 5. We'll multiply the numerator and the denominator of the first fraction by 6 and the numerator and the denominator of the second fraction by 5 so the denominators are the same.
\(\frac{3\times 6}{10\times 6}=\frac{18}{60}\)\(\frac{1\times 5}{12\times 5}=\frac{5}{60}\)Now, compare both numerators so we can determine which fraction is greater. 18 is greater than 5 so the first fraction is greater. That means there are more flute players than trumpet players in the band.

Tap A takes 6 minutes to fill a tank and tap b takes 9 minutes to fill the same tank. Pipe C can empty the tank in 15 minutes. How long will it take to fill the tank if the pipe is in use when both taps are turned on
Answer: approximately 4.7368 minutes
This decimal value is the result of computing 90/19
=====================================================
Explanation:
Let's find the LCM of 6, 9 and 15. First, list out the prime factorization of each value.
6 = 2*39 = 3*315 = 3*5The unique prime factors are 2, 3, and 5. We have 2 show up at most once, 3 show up at most twice, and 5 show up at most once. The LCM is 2^1*3^2*5^1 = 2*9*5 = 18*5 = 90.
We'll use this LCM value to set up an example below.
---------------
Consider the tank to be 90 gallons. If we only use tap A, keep tap B closed, and don't open pipe C, then tap A fills the tank at a rate of 90/6 = 15 gallons per minute since it needs 6 minutes to completely fill the tank.
If we have tap B do all the work (keep tap A and pipe C closed), then the rate is 90/9 = 10 gallons per minute for this tap.
Keeping pipe C closed, the two taps A and B work together to have a combined rate of 15+10 = 25 gallons per minute.
Now we consider pipe C being opened. This drains the tank and can do so in 15 minutes (assume the taps A and B aren't open). If we're dealing with a full 90 gallon tank, then its rate is 90/15 = 6 gallons per minute.
The net rate is 25-6 = 19 gallons per minute. We can think of it as a tug of war where the taps A and B ultimately win out despite the fact that pipe C is draining the water. The two taps fill the tank faster than the pipe can drain the tank.
In other words, the tank ultimately gets filled up rather than drained out over the long run. That net speed is at 19 gallons per minute.
The amount of time needed is approximately 90/19 = 4.7368 minutes.
Side note: you can start with any size tank. It doesn't have to be 90 gallons. I picked on this value because it works cleanly with the original given numbers 6, 9 and 15.
Answer:
\(x=\frac{90}{19}\) = 4.73 minutes
\(\frac{1}{6}x +\frac{1}{9}x - \frac{1}{15} x = 1\)
\(\frac{135}{810}x +\frac{90 }{810}x - \frac{54}{810} x = 1\)
\(\frac{171}{810}x = 1\)
x = 4.73 minutes

The sides of a triangle are 77, 56, and 59. Use the Pythagorean Theorem to determine if the triangle is right, acute, or obtuse.
Answer:
Acute
Step-by-step explanation:
The Pythagorean Theorem refers to \(a^{2} + b^{2} =c^{2}\), no (and only on right angled triangles)? We would have to use the cosine and sine rules to answer this question.
First, lets use the cosine rule to get an angle, then use the sine rule to get another, which would allow us to then determine the third, which will allow us to determine the type of triangle.
\(cosA= \frac{b^2+c^2-a^2}{2bc}\) → \(cosA= \frac{77^2+56^2-59^2}{2(77)(56)}\) → \(cosA= \frac{5584}{8624}\) → \(cos^{-1}\frac{5584}{8624} = A\) → \(A = 49.65 = 50\)~
Now we can use the sine rule to find the other angles:
\(\frac{sin50}{59} = \frac{sinB}{77}\) → \(77\frac{sin 50}{59} = sin B\) → \(sinB = 0.9997529...\) → \(sin^{-1} 0.9997529... = B = 88.726... = 89\)~
So, if A = 50° and B = 89°, that would mean that the remaining angle is \(180 - 50-89=180-139=41\)
A = 50°
B = 89°
C = 41°
As none of the angles exceed or are equal to 90°, it must be an acute triangle!
