Step-by-step explanation:

the arc angle KLI = 142°.

that means that the arc angle KJI = 360 - 142 = 218°.

this is twice the inscribed opposite angle on the arc (L).

so,

(a)

angle KLI = 218/2 = 109°

(b)

for the same reason

angle LKJ is half of the arc angle LIJ.

arc angle LIJ = 2× angle LKJ = 2×66 = 132°

that means

arc angle LKJ = 360 - 132 = 228°

angle LIJ = half of arc angle LKH = 228/2 = 114°

FYI for such an inscribed quadrilateral there is Akari the rule that the sum of opposite angles have to be 180°.

so, angle LIJ is opposite of angle LKJ.

angle LIJ = 180 - angle LKJ = 180 - 66 = 114°

Therefore , the solution of the given problem of median comes out to be  R students still present (maximum) =35

The number that precisely falls in the center of a sorted collection is the median value. An average or maximum probability metric is the difference between the initial and final 50% of the data. Different algorithms are employed to compute the average and mode depending on if you do have an unusual or perhaps even number of data points.

Here,

Median is 55

P :Q: R :S :average of 45 :50: 55 :65

The number of pupils within every section needs to be as low as possible 

R is a mean

P differs by 1: 10 from the mean.

Q is 1.5 away from the mean.

Then S will just have three students, or three times five, to keep the population's mean constant.

R students still present (maximum):

=> 40 - 1- 1-3

Answer:15216.31 Fluid Ounces

Step-by-step explanation:

The object will reach a height of 197 feet at approximately 0.325 seconds and 9.6 seconds, and it will reach the ground at approximately 0.009 seconds and 9.975 seconds.

To find when the height of the object is 197 feet, we can set the equation \(h = -16t^2 + 159t + 7\) equal to 197 and solve for t:

\(-16t^2 + 159t + 7 = 197\)

Rearranging the equation:

\(-16t^2 + 159t - 190 = 0\)

Now, we can solve this quadratic equation either by factoring, completing the square, or using the quadratic formula. Let's use the quadratic formula:

t = (-b ± √\((b^2 - 4ac))\) / (2a)

Plugging in the values:

t = (-(159) ± √\(((159)^2 - 4(-16)(-190)))\) / (2(-16))

Simplifying:

t = (-159 ± √(25281 - 12160)) / (-32)

t = (-159 ± √13121) / (-32)

Now, calculating the values:

t ≈ 0.325 seconds or t ≈ 9.6 seconds

To find when the object reaches the ground, we need to determine the time when the height h becomes zero:

\(-16t^2 + 159t + 7 = 0\)

Solving this quadratic equation using the quadratic formula:

t = (-159 ± √\((159^2 - 4(-16)(7)))\) / (2(-16))

Simplifying:

t = (-159 ± √(25281 + 448)) / (-32)

t = (-159 ± √25729) / (-32)

Calculating the values:

t ≈ 0.009 seconds or t ≈ 9.975 seconds

By convention, we use a bar graph when the groups on the x-axis (horizontal axis) are represented on a categorical or discrete scale; we use a line graph when the groups on the x-axis are represented on a continuous or numerical scale.

A bar graph is commonly used to display categorical or discrete data, where the groups or categories on the x-axis are distinct and separate from each other.

For example, the x-axis could represent different types of fruits or months of the year. Each category is represented by a separate bar, and the height of each bar corresponds to the frequency, count, or value associated with that category.

On the other hand, a line graph is typically used to represent data on a continuous or numerical scale. The x-axis represents a continuous range of values, such as time, temperature, or distance.

Each data point is plotted as a dot or marker on the graph, and the points are connected by lines. This type of graph is useful for showing trends, patterns, or changes over time or across a continuous range.

The choice of using a bar graph or a line graph depends on the nature of the data and the purpose of the visualization. Categorical data is best represented using a bar graph to emphasize the distinct categories, while numerical or continuous data is better suited for a line graph to visualize trends and relationships.

Answer:

X-1 X-1 X-1 28

Step-by-step explanation:

The given statement is true. No polygon exists in which the ratio of the number of diagonals to the sum of the measures of the polygon's angles is 1 to 18.

To prove this, we can use the formula for the number of diagonals in a polygon, which is (n(n-3))/2, where n is the number of sides. The sum of the measures of the angles in a polygon is (n-2)180 degrees.

Setting the ratio of diagonals to the sum of the angles equal to 1/18, we get:

(n(n-3))/2 / (n-2)180 = 1/18

Simplifying, we get:

n(n-3) = 360(n-2)

Expanding and simplifying, we get:

n^2 - 363n + 720 = 0

Using the quadratic formula, we find that the solutions are approximately 2.5 and 360.5. Since a polygon must have a whole number of sides, the only possible solution is n=361.

However, when we substitute n=361 into the original equation, we find that the ratio is actually 1/180, not 1/18. Therefore, no polygon exists that satisfies the given ratio.

The price for printing 700 cards is $15+$700/25 = $43.

Explanation:

We need to MODEL the cost based on the number of cards printed. We will assume that there is a FIXED price

Let's see

Total votes be x

Now total percentage of vote

Not voted=4%

Find not voted

Total voted

Answer:

73649 of 80000 (or 91.8%)

Step-by-step explanation:

Note:  An electorate is a person who is entitled to vote in an election - it does not necessarily mean they have voted in the election.

If 36000 votes represents 45% of the electorate (note: it does not say this figure represents 45% of the votes), then the total number of electorates is:

\(\implies \sf \dfrac{36000}{45}\times 100=80000\)

If three candidates received 25%, 20% and 6% of the votes, then the winning candidate received:

⇒ 100% - 25% - 20% - 6% = 49% of the votes

If the winning candidate received 36,000 votes, then:

⇒ 49% of the votes = 36,000 votes

Therefore, the total number of votes is:

\(\implies \sf \dfrac{36000}{49}{ \times 100=73469\)

To find the percentage of electorates that voted:

\(\implies \sf \dfrac{73469}{80000} \times 100=91.8\% \:\: (1\:d.p.)\)

First, you know that Jackson (let call her J) scored 42 more points than L (Leslie).  What we don't know is how many points L scored so we can use a variable that will be 'x'.

So the equation will be J=42+x.

We also know that the total points is 1,144.

To find out what x is we first subtract 1,144-42.  We then get 1,102.

We are now left with 2x and 1,102 so we divide 1,102 by 2 and get 551.

551=x so now we can plug that in.

J = 551 + 42

Jackson scored 593 points and Leslie scored 551 points

Row operations on a matrix can change its eigenvalues.

Eigenvalues are defined as the values of λ for which the equation (A - λI)x = 0 has a non-zero solution x. Here, A is the matrix, λ is the eigenvalue, I is the identity matrix, and x is the eigenvector.

When we perform row operations on a matrix A, we are essentially multiplying A by an elementary matrix E. This changes the matrix A to a new matrix B = EA.

The eigenvalues of the new matrix B are not necessarily the same as the eigenvalues of the original matrix A. However, the eigenvalues of A and B do have the same algebraic multiplicity, which is the number of times each eigenvalue appears as a root of the characteristic polynomial of the matrix.

So while row operations on a matrix can change its eigenvalues, they do not change the algebraic properties of the eigenvalues, such as their multiplicity.
