Answer:

mean- 32.4

median- 31.5

mode- 35

Step-by-step explanation:

to find mean add up all the number together than divide it by how many number that are there

for example the total is 324 and you would divide it by 10 (since there are 10 number there)

to find median locate the middle number but since you have two number in the middle take those to number add them together and divide by 2

for example 31+32=63 than divide by 2 which is 31.5

to find mode it is the number that appears most often so it would be 35 since it appears most often

For the polynomials p(x) = 1 - x + 4x² and q(x) = x - x², (p, q) = 10, ||p|| = √18, ||a|| = √18, and d(p, q) cannot be determined. For the vectors u = (0, 2, 3) and v = (2, 3, 0), (u, v) = 6, ||u|| = √13, ||v|| = √13, and d(u, v) cannot be determined.

In the first scenario, we have p(x) = 1 - x + 4x² and q(x) = x - x². To find (p, q), we substitute the coefficients of p and q into the inner product formula:

(p, q) = (1)(0) + (-1)(2) + (4)(3) = 0 - 2 + 12 = 10.

To calculate ||p||, we use the formula ||p|| = √((p, p)), substituting the coefficients of p:

||p|| = √((1)(1) + (-1)(-1) + (4)(4)) = √(1 + 1 + 16) = √18.

For ||a||, we can use the same formula but with the coefficients of a:

||a|| = √((1)(1) + (-1)(-1) + (4)(4)) = √18.

Lastly, d(p, q) represents the distance between p and q, which can be calculated as d(p, q) = ||p - q||. However, the formula for this distance is not provided, so it cannot be determined. Moving on to the second scenario, we have u = (0, 2, 3) and v = (2, 3, 0). To find (u, v), we use the given inner product formula:

(u, v) = (0)(2) + (2)(3) + (3)(0) = 0 + 6 + 0 = 6.

To find ||u||, we use the formula ||u|| = √((u, u)), substituting the coefficients of u:

||u|| = √((0)(0) + (2)(2) + (3)(3)) = √(0 + 4 + 9) = √13.

Similarly, for ||v||, we use the formula with the coefficients of v:

||v|| = √((2)(2) + (3)(3) + (0)(0)) = √(4 + 9 + 0) = √13.

Unfortunately, the formula for d(u, v) is not provided, so we cannot determine the distance between u and v.

Each Bj is an open interval or a set of the form (a,b) ∩ K, each Bj is open in the topology generated by B. Hence, U is a union of open sets in the topology generated by B and the topology generated by B is finer than the standard topology.

Given that K = {x : x is not a positive integer}. Also, B is the collection of open intervals (a,b) along with all sets of the form (a,b) ∩ K. We need to prove that the topology on R generated by B is finer than the standard topology on R.

Let's start with the following lemma:

Lemma: Every open interval in the standard topology is a union of elements of B.

Proof: Let (a,b) be an open interval in the standard topology. If (a,b) ∩ K = ∅, then (a,b) ∈ B and we are done. Otherwise, we can write(a,b) = (a,c) ∪ (c,b)where c is the smallest positive integer such that c > a and c < b.

Now, (a,c) ∩ K and (c,b) ∩ K are both in B. Therefore, (a,b) is a union of elements of B.

Now, let's prove that B generates a finer topology on R than the standard topology.

Let U be an open set in the standard topology and x be a point in U. Then there exists an open interval (a,b) containing x such that (a,b) ⊆ U. By the above lemma, we can write (a,b) as a union of elements of B.

Therefore, there exist elements B1, B2, ..., Bn of B such that (a,b) = B1 ∪ B2 ∪ ... ∪ Bn.

Since each Bj is an open interval or a set of the form (a,b) ∩ K, each Bj is open in the topology generated by B. Therefore, (a,b) is a union of open sets in the topology generated by B.

Hence, U is a union of open sets in the topology generated by B. Therefore, the topology generated by B is finer than the standard topology.

After the hurricane and the disease, 48% of the original population of rats is left.

We have,

After the hurricane, 40% of the rats were wiped out, which means

100% - 40% = 60% of the rats survived.

Then, after the disease spread through stagnant water, 20% of the remaining rats were killed.

This means 100% - 20% = 80% of the rats that survived the hurricane are still left.

To find the percentage of the original population of rats that is left after both events, we multiply the percentages:

Percentage left = 60% * 80% = 0.6 * 0.8 = 0.48

Finally, we convert the decimal value back to a percentage:

Percentage left = 0.48 * 100% = 48%

Therefore,

The distance between the car and Johnstown is decreasing at a rate of 33 miles per hour.

After travelling 63 miles, the distance between the car and Johnstown is changing at a rate of 33 miles per hour, and the distance between the car and Johnstown is 100 miles

To calculate the distance between the car and Johnstown after travelling 63 miles, we need to first find the starting distance.

The car starts off 163 miles directly north from the city of Johnstown, so the starting distance is 163 miles.

We then need to subtract the distance travelled from this starting distance. Since the car is travelling at a rate of 33 miles per hour, it has travelled 63 miles in the given time.

Therefore, the distance between the car and Johnstown is 100 miles

(163 - 63 = 100).

Finally, we need to calculate the rate of change of this distance. Since the car is travelling at a rate of 33 miles per hour, the rate of change of the distance between the car and Johnstown is also 33 miles per hour.

The growth rate of the population is given by 14,000t, the population after 15 years is 1,975,000, the growth rate at t = 15 is 210,000, and it represents the rate at which the population is increasing at that specific point in time.

To find the growth rate of the population, we need to take the derivative of the population function P(t) with respect to t, which represents the rate at which the population is changing over time.

a) dP/dt = d/dt (400,000 + 7000t²)

= 0 + 2(7000)t

= 14,000t

The growth rate of the population is given by the derivative dP/dt, which is 14,000t.

b) To find the population after 15 years, we substitute t = 15 into the population function P(t).

P(15) = 400,000 + 7000(15)²

= 400,000 + 7000(225)

= 400,000 + 1,575,000

= 1,975,000

The population after 15 years is 1,975,000.

c) To find the growth rate at t = 15, we substitute t = 15 into the derivative dP/dt.

dP/dt (15) = 14,000(15)

= 210,000

The growth rate at t = 15 is 210,000.

d) The meaning of the growth rate at t = 15 (210,000) is that at that specific point in time, the population is growing at a rate of 210,000 individuals per year. This indicates how fast the population is increasing at that particular time.

Therefore, The growth rate of the population is given by 14,000t, the population after 15 years is 1,975,000, the growth rate at t = 15 is 210,000, and it represents the rate at which the population is increasing at that specific point in time.

In the fire academy, with a ratio of 7 passing grades to 5 failing grades, we find that approximately 15 students failed.

Given the ratio of 7 passing grades to 5 failing grades, we can set up a proportion to determine the number of students who failed out of 36 students.

Let's denote the number of students who failed as x.

The proportion can be set up as follows:

7 passing grades / 5 failing grades = 36 total students / x failed students

Cross-multiplying the proportion, we have:

7x = 5 * 36

Simplifying the equation, we get:

7x = 180

Dividing both sides of the equation by 7, we find:

x = 180 / 7

Calculating the value, we have:

x ≈ 25.71

Since we cannot have fractional students, we round down to the nearest whole number.

Therefore, approximately 25 students failed out of the 36 students in the fire academy.

False. Randomization distributions are centered at the value where the null is false. This distinction is important in hypothesis testing as it helps determine the statistical significance of observed differences or effects.

Randomization distributions are generated through permutation tests, which involve random shuffling of data points between groups. In hypothesis testing, the null hypothesis assumes that there is no difference between groups or no effect of a treatment. The alternative hypothesis suggests otherwise.

The randomization distribution is created by repeatedly shuffling the data and calculating a test statistic based on the null hypothesis. This distribution represents the expected outcomes if the null hypothesis is true. Therefore, the randomization distributions are centered at the value where the null is false, as they capture the potential differences or effects between groups.

In summary, randomization distributions are not centered at the value where the null is true; rather, they are centered at the value where the null is false. This distinction is important in hypothesis testing as it helps determine the statistical significance of observed differences or effects.

Answer: (1,3)

Step-by-step explanation: All you're doing with this outward-shaded parabola is just seeing which points are in the red and which points are not. The point that isn't in the red is the point not included in the solution set. If you plot all the points given, you'll see that (1,3) is in the white. :)

The point (-2, 1) is not included in the solution set.

The given inequality describes an upward opening parabola with a dashed line. The vertex of the parabola is (1, 2), and it passes through the points (-1, 6) and (3, 6). The shading outside the curve represents the solution set for the inequality.
To determine which point is not included in the solution set, we can test each point in the inequality. Let's start with (-2, 1).

Plugging in the x- and y-coordinates of (-2, 1) into the inequality, we get: 1 < (2 - 1)^2. Simplifying this inequality, we have 1 < 1, which is false. Therefore, (-2, 1) is NOT included in the solution set.

Now, let's test the remaining points: (1, 3), (4, 3), and (5, -1). By substituting these points into the inequality, we can determine whether they satisfy the inequality or not.

Based on our calculations, the point that is not included in the solution set for the inequality is (-2, 1).
