Verify that both y₁(t) = 1 - t and y₂(t) = -t²/4 are solutions of the initial value problem Where are these solutions valid? Explain why the existence of two solutions of the given problem does not contradict the uniqueness part of Show that y = ct + c², where c is an arbitrary constant, satisfies the differential equation in part the initial condition is also satisfied, and the solution y = y₁(t) is obtained. Show that there is no choice of c that gives the second solution y = y₂(t).
Replacing y(t) into the initial value, we reach an identity, meaning that it can be verified that both y(t) = 1 - t and y(t) = -t²/4 are solutions to the initial value problem.
How to verify the solutions to the initial problem?The initial value problem is defined as follows:

Let [r, s] denote the least common multiple of positive integers r and s. Find the number of ordered triples (a, b, c) of positive integers for which [a, b] = 1000, [b, c] = 2000, and [c, a] = 2000.
Solution 1
It's clear that we must have a = 2^j5^k, b = 2^m^6 and c = 2^p5^q for some nonnegative integers j, k, m, n, p, q. Dealing first with the powers of 2: from the given conditions, max(j, m)=3, max(m, p) = max(p, j) = 4. Thus we must have p = 4 and at least one of m, j equal to 3. This gives 7 possible triples (j,m,p): (0, 3, 4), (1, 3, 4), (2, 3, 4), (3, 3, 4), (3, 2, 4), (3, 1, 4) and (3, 0, 4).
Now, for the powers of 5: we have max (k, n) = max(n, q) = max(q, k) = 3. Thus, at least two of k, n, g must be equal to 3, and the other can take any value between 0 and 3. This gives us a total of 10 possible triples: (3, 3, 3) and three possibilities of each of the forms (3, 3, n), (3, n, 3) and (n, 3, 3).
Since the exponents of 2 and 5 must satisfy these conditions independently, we have a total of 7. 10= 70 possible valid triples.
Solution 2
1000=2³5³ and 2000= 2⁴5³. By looking at the prime factorization of 2000, c must have a factor of 2¹. If c has a factor of 53, then there are two cases: either (1) a or b = 5³2³, or (2) one of a and has a factor of 5³ and the other a factor of 2³. For case 1, the other number will be in the form of 2^x5^y, so there are 4 4 16 possible such numbers; since this can be either a orb there are a total of 2(16)-1=31 possibilities. For case 2, a and b are in the form of 2³5^x and 2^y5³, with a x<3 and y<3 (if they were equal to 3, it would overlap with case 1). Thus, there are 2(3-3)= 18 cases.
If c does not have a factor of 5³, then at least one of a and b must be 2³5³, and both must have a factor of 5³. Then, there are 4 solutions possible just considering a = 2353, and a total of 4.2-17 possibilities. Multiplying by three, as 0<=c<=2, there are 7.3 = 21.
Together, that makes 31 +18+21= 70 solutions for (a, b, c).

For a frequency polygon to display the distribution of data accurately, intervals of equal width must be used.
a) Explain why, using examples.
b) Can some of the data be left out of the frequency polygon? Justify your answer.
a. The intervals of equal width must be used because it allows for a fair comparison.
b. Some of the data can be left out of the frequency polygon if it is not relevant to the analysis.
How to explain the polygon?a) For a frequency polygon to accurately display the distribution of data, intervals of equal width must be used because it allows for a fair comparison between different parts of the data. If the intervals are not equal in width, it can give the impression that there are more or fewer data points in a particular interval, which can be misleading.
For example, if we have data on the heights of 100 people and we want to create a frequency polygon to display this data, we would first need to decide on the intervals that we want to use. If we use intervals of equal width, such as 1 inch, it would allow us to fairly compare the number of people who are between 5'0" and 5'1", 5'1" and 5'2", and so on. However, if we use intervals of unequal width, such as 1 inch for heights between 5'0" and 5'3", and 2 inches for heights between 5'3" and 5'6", it would give the impression that there are fewer people in the second interval than in the first, even if that is not the case.
b) Some of the data can be left out of the frequency polygon if it is not relevant to the analysis that we are trying to perform. For example, if we are interested in understanding the distribution of heights among people who are between the ages of 18 and 25, we could exclude data on the heights of people who are outside of this age range from our frequency polygon.
However, it is important to be careful about which data we choose to exclude, as it can significantly affect the interpretation of the results. If we exclude too much data, it could lead to a distorted view of the distribution of the data.

In a survey, 14 people were asked how much they spent on their child's last birthday gift. The results were roughly bell-shaped with a mean of $50 and standard deviation of $13. Construct a confidence interval at a 95% confidence level.
Give your answers to one decimal place.
The 95% confidence interval for the amount spent on the child's last birthday gift is between $44.5 and $55.5.
To construct a 95% confidence interval, we first calculate the margin of error, which is equal to 1.96 times the standard deviation divided by the square root of the sample size.
In this case, the margin of error is 1.96 x 13/√14 = $5.5. Then, we add the margin of error to the mean to obtain the upper bound of the confidence interval, which is 50 + 5.5 = $55.5. We subtract the margin of error from the mean to obtain the lower bound of the confidence interval, which is 50 - 5.5 = $44.5.
Finally, we round the upper and lower bounds to the nearest decimal place, which gives us the 95% confidence interval of (36.4, 63.6).
