All parts are equal to one therefore raisons are just 1 out of 7 other slices on the pie chart

To determine what part of the premium trail mix is composed of raisins, refer to the given pie chart. The portion represented by 'raisins' indicates the amount of raisins in the mix. Raisins slice is 1/7, so 14.28% of premium blend is composed of raisins.

To find out what part of the premium blend trail mix is composed of raisins, you need to look at the pie chart. The pie chart should be separated into multiple sections, with each section representing a different ingredient in the trail mix. The section labeled as raisins would represent the part of the premium blend that is composed of raisins.

For example, if the 'raisins' slice is 1/4, 25%, or 90 degrees of the pie chart, this means that 1/4, 25%, or a proportional quantity of the trail mix is composed of raisins. This is because a pie chart is a circle, and a full circle is 100% or 360 degrees - so 1/4, 25%, or 90 degrees all represent the same quantity in this context.

Remember to always check the labels and any information provided in the pie chart. It provides a visual representation of data and can help you understand the proportions of different components in a mixture.

If the line segment joining the points A (x1, y1) and B(x2, y2) is divided by a point P in the ratio 1 : k internally, then the coordinates of the point P are P[(1x₂ + kx₁)/(1 + k)],  [(1y₂ + ky₁)/(1 + k)].

In this scenario, we would use line ratio to determine the coordinates of the point P on the directed line segment that partitions the segment into a ratio of 1 to k.

In Mathematics, line ratio can be used to determine the coordinates of the point P and this is modeled by this mathematical expression:

P(x, y) = [(mx₂ + nx₁)/(m + n)],  [(my₂ + ny₁)/(m + n)]

Substituting the given parameters into the line ratio formula, we have the following;

Answer:

Step-by-step explanation:

You want an equation for the temperature of 8 cups of hot (50 °C) water combined with c cups of cold (20 °C) water, along with an explanation of it. Then you want the number of cups required to reduce the temperature to 40 °C.

Assuming constant heat capacity and volume as a function of temperature, the temperature of the mix will be the weighted average of the temperatures of the contributors. That is c cups of water at 20 °C combined with 8 cups of water at 50 °C will have a temperature (t) of ...

  t = (20c +8(50))/(c+8)

  t = (20c +400)/(c +8)

The thermal energy contained in the water is assumed to be jointly proportional to its volume and its temperature. The combined thermal energy of the mixture will be the total of that of its contributors.

That is, the temperature of the mix is the weighted sum of the temperatures of the contributors, the weights being their respective volumes.

The value of c for a temperature of 40 °C is ...

  40 = (20c +400)/(c+8)

  2(c +8) = c +20) . . . . divide by 20, multiply by (c+8)

  2c +16 = c +20 . . . . eliminate parentheses

  c = 4 . . . . . . . . . . . . subtract (c+16)

4 cups of cold water must be added to reduce the temperature ot 40 °C.

(a) t = (400 + 20c)/(8+c)

(b)weighted sum of temperatures

(c) 4 cups

An equation is a statement that asserts the equality of two expressions, the expressions are written one on each side of an '=' equal to sign.

Let t be the temperature of water.

Let c be the number of cold cup of water at 20°C

(a)c cups of water at 20 °C combined with 8 cups of water at 50 °C will have a temperature (t) of

[tex]t= \frac{20c+8*50}{c+8}[/tex]  --------(1)

(b)The temperature of the mix is the weighted sum of the temperatures of the contributors, the weights being their respective volumes.

(c)The value of c for a temperature of 40 °C is

40 = (20c +400)/(c+8)

2(c +8) = c +20) . . . . divided by 20, multiply by (c+8)

2c +16 = c +20 . . . . eliminate parentheses

⇒ c = 4

Hence, the required equation is [tex]t= \frac{20c+8*50}{c+8}[/tex] and for part (c) 4 cups.

If sample variance were to be computed by dividing SS by n, then the average value of the sample variances from all the possible random samples would consistently underestimate the population variance.

The sample variance is an estimate of the population variance, and it is calculated by dividing the sum of squared deviations (SS) by the sample size minus one (n - 1).

The reason for dividing by n-1 instead of n is due to the fact that the sample variance is an estimate of the population variance and not the exact value. When computing the sample variance, we use the sample data to make an estimate of the population variance. By dividing by n-1 instead of n, we adjust for the fact that the sample is a subset of the population and introduce a small amount of bias into the estimate to correct for this lack of representation.

This correction is known as the Bessel's correction and it makes the sample variance a more accurate estimate of the population variance by adjusting for the variability inherent in sampling. As a result, when sample variance is computed using the Bessel's correction (dividing by n-1), the average value of the sample variances from all possible random samples will consistently underestimate the population variance.

The probability that a randomly selected student takes both computer science and statistics courses is 26%.

Let's call the event that a student takes a computer science course "C" and the event that a student takes a statistics course "S". We want to find the probability that a student takes both C and S, which can be written as P(C ∩ S).

The probability that a student takes at least one of these two courses can be written as P(C ∪ S), which is equal to 63%. This means that 63% of the students take either computer science or statistics, or both.

To find the probability that a student takes both courses, we can use the formula for the intersection of two events:

P(C ∩ S) = P(C | S) × P(S)

where P(C | S) is the probability that a student takes a computer science course given that they also take a statistics course. To find this value, we can use the formula:

P(C | S) = P(C ∩ S) ÷ P(S)

Substituting this into the first equation, we get:

P(C ∩ S) = P(C ∩ S) ÷ P(S) × P(S)

P(C ∩ S) = P(C ∩ S) × P(S)

We know that P(S) = 48% and we can use the formula for the union of two events to find P(C ∪ S):

P(C ∪ S) = P(C) + P(S) - P(C ∩ S)

Substituting in the values we know:

63% = 41% + 48% - P(C ∩ S)

P(C ∩ S) = 41% + 48% - 63% = 26%

Step-by-step explanation:

There does not exist a constant C > 0 such that p∞(v) ≤ Cp1(v) for all vectors v in V. Therefore, p1-norm < p2-norm < p∞-norm implies there is no c such that p∞-norm < c p1-norm.

Given two norms, p and q, on a vector space V, we say that p is less than q, written p ≤ q, if there exists a constant C > 0 such that for all vectors v in V,

p(v) ≤ Cq(v)

Now, let's consider the three norms:

   The 1-norm: p1(v) = ∑|v_i|

   The 2-norm: p2(v) = √(∑v_i^2)

   The infinity-norm: p∞(v) = max{|v_i|}

We are given that p1(v) ≤ p2(v) for all vectors v in V and that p2(v) ≤ p∞(v) for all vectors v in V. We want to show that there does not exist a constant C > 0 such that p∞(v) ≤ Cp1(v) for all vectors v in V.

Suppose for the sake of contradiction that such a constant C does exist. Then, for any non-zero vector v in V,

p∞(v) ≤ Cp1(v)

max{|v_i|} ≤ C ∑|v_i|

Since v is non-zero, there exists an index i such that |v_i| > 0. We can divide both sides of the inequality by |v_i| to get:

1 ≤ C ∑|v_j| / |v_i|

Now, since p1(v) ≤ p2(v) for all vectors v in V, we have:

p1(v) = ∑|v_j| ≤ √(∑v_j^2) = p2(v)

So, we can substitute this into the inequality above to get:

1 ≤ C √(∑v_j^2) / |v_i| = Cp2(v) / |v_i|

Finally, since p2(v) ≤ p∞(v) for all vectors v in V, we have:

p2(v) / |v_i| ≤ p∞(v) / |v_i| = 1

So, we have reached a contradiction:

1 ≤ Cp2(v) / |v_i| ≤ C

This contradicts the assumption that C > 0, so there does not exist a constant C > 0 such that p∞(v) ≤ Cp1(v) for all vectors v in V. Therefore, p1-norm < p2-norm < p∞-norm implies there is no c such that p∞-norm < c p1-norm.
