The equation of the line in the graph is:

y = 2

A general linear equation can be written as:

y = ax + b

Where a is the slope and b is the y-intercept.

Particularly, in this case we can see that the line intercepts the y-axis at the value y = 2, then we have that b = 2

y = ax + 2

Now we can see that the line also passes through the point (5, 2), replacing these values in the equation we get:

2 = a*5 + 2

2 - 2 = a*5

0 = a*5

0/5 = a

The area of the rectangular farm is 197,600 square meters.

Let's assume the breadth of the rectangular farm is x meters. According to the given information, the length of the farm is 140 meters longer than its breadth, so the length would be (x + 140) meters.

The perimeter of a rectangle is given by the formula P = 2(length + breadth). We can set up the equation as follows:

2(length + breadth) = 1800

Substituting the values, we get:

2((x + 140) + x) = 1800

Simplifying the equation:

2(2x + 140) = 1800

4x + 280 = 1800

4x = 1800 - 280

4x = 1520

x = 1520 / 4

x = 380

Therefore, the breadth of the farm is 380 meters.

Using this value, we can find the length:

Length = x + 140 = 380 + 140 = 520 meters.

The area of a rectangle is given by the formula A = length * breadth. Substituting the values, we have:

Area = 520 * 380 = 197,600 square meters.

The null hypothesis for this test is that the mean weight of adult cats of the same breed is equal to 9.0 lb, while the alternative hypothesis is that it is different from 9.0 lb.

In statistical hypothesis testing, the null hypothesis is a statement that is assumed to be true unless there is sufficient evidence to reject it in favor of an alternative hypothesis. In this case, the null hypothesis is that the mean weight of adult cats of the same breed is equal to 9.0 lb, which is what we are trying to test. The alternative hypothesis, on the other hand, is that the mean weight of adult cats of the same breed is different from 9.0 lb, which could be either higher or lower. This is the hypothesis that we would accept if there is sufficient evidence to reject the null hypothesis.

To test these hypotheses, we would need to collect a sample of adult cats of the same breed, measure their weights, and calculate the sample mean. We could then use statistical methods to determine whether the sample mean is significantly different from the hypothesized value of 9.0 lb. If it is, we would reject the null hypothesis in favor of the alternative hypothesis.

We are given a sample of n=712 20 29 year old men, with a sample mean weight of 183 pounds. We are also told that the population standard deviation is 40 pounds.

To calculate the confidence interval, we use the formula

Zα/2 is the critical value of the standard normal distribution at a significance level of α/2, σ is the population standard deviation, and n is the sample size.

The critical value of the standard normal distribution at a 90% confidence level is 1.645. Plugging in the provided values, we get:

CI = 183 1.645 * (40/√712)

CI = [179.86, 186.14]

This means we can be 90% confident that the true population mean weight of 20 29 year old men lies within the range of 179.86 to 186.14 pounds.

In summary, based on the sample of 712 men and the given population standard deviation of 40 pounds, we can estimate the population mean weight with 90% confidence to be between 179.86 and 186.14 pounds.

The null hypothesis is that the proportion of residents in favor of annexation is equal to or greater than 44%, while the alternative hypothesis is that the proportion is less than 44%. A significance level of 0.02 will be used to determine if there is sufficient evidence to support the mayor's claim.

The null hypothesis (H0) is a statement of no difference or no effect, while the alternative hypothesis (H1) is a statement of the expected difference or effect. In this case, the null hypothesis is that p >= 0.44, where p is the proportion of residents in favor of annexation. The alternative hypothesis is that p < 0.44.

To test the hypothesis, a sample of residents can be taken and the proportion of those in favor of annexation can be calculated. Then, a hypothesis test can be performed using the sample proportion and the null hypothesis to determine if there is sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis. A significance level of 0.02 means that if the p-value (the probability of obtaining a test statistic as extreme as the one observed, assuming the null hypothesis is true) is less than 0.02, then the null hypothesis will be rejected in favor of the alternative hypothesis.

The number of ways to select 6 pieces of candy from a bag containing 14 pieces can be calculated using the combination formula. There are 3003 different ways to select six pieces of candy from a bag containing 14 pieces.

which is:

nCr = n! / (r! * (n-r)!)

where n is the total number of candies in the bag (14), and r is the number of candies to be selected (6).

Using this formula, we get:

14C6 = 14! / (6! * (14-6)!)
= 3003

Therefore, there are 3003 ways to select 6 pieces of candy from a bag containing 14 pieces.

To determine the number of ways six pieces can be selected from a bag containing 14 pieces of candy, you can use the concept of combinations. Combinations are used when the order of selection does not matter.

The formula for combinations is:
C(n, r) = n! / (r!(n-r)!)

In this case, n = 14 (total pieces of candy) and r = 6 (number of pieces to be selected).

Using the formula:

C(14, 6) = 14! / (6!(14-6)!)

C(14, 6) = 14! / (6! * 8!)

Now, calculate the factorials:

14! = 14 * 13 * 12 * 11 * 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1
6! = 6 * 5 * 4 * 3 * 2 * 1
8! = 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1

Then, substitute the factorials back into the equation:

C(14, 6) = (14!)/(6! * 8!)

C(14, 6) = (87178291200)/(720 * 40320)

Finally, divide the numerator by the denominator:

C(14, 6) = 3003

So, there are 3003 different ways to select six pieces of candy from a bag containing 14 pieces.

Answer:

Step-by-step explanation:

We must divide the frequency of F grades by the total number of pupils in the class to get the likelihood that a student would receive an F.

The frequency distribution being what it is:

Level: A B C D F

28 35 56 14 7 times each year

You can determine the total number of pupils by adding the frequencies:

Students total: 28 + 35 + 56 + 14 + 7 = 140.

We can now determine the probability:

P(F) = Number of students overall / Frequency of F grades

P(F) = 7 / 140 P(F) = 0.05

As a result, the likelihood that a student will receive a F is 0.05, or 5%.

The critical numbers of the function f(theta) = 18 cos(theta) + 9 sin^2(theta) need to be found.

To find the critical numbers, we need to first take the derivative of the function.

f'(theta) = -18 sin(theta) + 18 sin(theta) cos(theta)

Setting f'(theta) equal to zero and solving for theta, we get:

-18 sin(theta) + 18 sin(theta) cos(theta) = 0

simplifying, we get:

sin(theta) (cos(theta) - 1) = 0

So, the critical numbers occur when sin(theta) = 0 or cos(theta) = 1.

Therefore, the critical numbers of the function are: theta = npi, where n is an integer, and theta = 2npi, where n is an integer.

Answer:

[tex]5 + 2\sqrt{3}[/tex]

    &          

[tex]5-2\sqrt{3}[/tex]

Step-by-step explanation:

Okay! The equation is : 2x²+26=20x

Right off the bat we notice that this can be simplified. We divide all numbers by a common multiple: 2.

Our resulting equation is [tex]x^2 + 13= 10x[/tex]

Now, in order to plug this equation into our quadratic formula, we need to rearrange this equation into the [tex]ax^2 + bx +c = 0[/tex] format.

In order to do that, we simply move the 10x to the left side of the equation, resulting in this: [tex]x^2 - 10x + 13[/tex]

Here is the quadratic formula:

(-b±√(b²-4ac))/ 2a

I will include a picture of the quadratic equation at the bottom (because the typed equation is strange).

So looking at our previously found formula, x^2 - 10x + 13, we know that a: 1

b: -10

c: 13

Now, we plug in our values!

(-(-10) ± √((-10)²-(4(1)(13))) / 2(1)

Simplify! (10 ± √(100-52)) / 2

Simplify again! (10 ± √48) / 2

Now we must simplify the square root. If we try to find the square root of 48, it comes out to 6.92820323, which is a very messy number. We will NOT be using this number. We will instead find the factors of 48.

2·2·2·2·3 = 48

So it looks like this: √2·2·2·2·3

We can pair up the similar numbers, so it looks like: √(2·2)(2·2)·3

Now, we move the pairs of twos to the front of the equation (but only one two from each pair is represented because they've been square-rooted) , and out of the square root, to get us: 2·2 √3, which equals 4√3

Now that we have the square root figured out, we re-enter the square root into the equation we had before (replacing the un-simplified version with the simplified version), which was (10 ± √48) / 2.

Here is the equation with the simplified root:  (10 ± 4√3) / 2

Now we notice that 10 and 4 are divisible by 2, so the equation becomes: (5 ± 2√3), which is 5+2√3, AND 5-2√3

(a) To calculate the probability of the first miss occurring after 12 attempts, we need to consider the scenario in which the shooter makes the first 11 shots and then misses the 12th shot. The probability of making a free throw is given as p = 0.9.

The probability of making a shot is 0.9, so the probability of missing a shot is 1 - 0.9 = 0.1. Therefore, the probability of making 11 shots in a row is (0.9)^11.

The probability of missing the 12th shot is 0.1. Since these events are independent, we can multiply the probabilities together. Therefore, the probability of making the first 11 shots and missing the 12th shot is (0.9)^11 * 0.1.

Therefore, the probability of having the first miss after 12 attempts is (0.9)^11 * 0.1.

(b) To calculate the probability that the third miss occurs on the 30th attempt, we need to consider the scenario in which the shooter makes the first 29 shots and then misses the 30th shot.

The probability of making a shot is 0.9, so the probability of missing a shot is 1 - 0.9 = 0.1. Therefore, the probability of making 29 shots in a row is (0.9)^29.

The probability of missing the 30th shot is 0.1. Since these events are independent, we can multiply the probabilities together. Therefore, the probability of making the first 29 shots and missing the 30th shot is (0.9)^29 * 0.1.

However, we also need to consider that the shooter must miss the first two shots before reaching the 30th attempt. The probability of missing two shots in a row is (0.1)^2.

Therefore, the probability that the third miss occurs on the 30th attempt is (0.9)^29 * 0.1 * (0.1)^2.

Note that these calculations assume that each shot is independent of the others and that the shooter's probability of making a shot remains constant throughout the attempts.

The set of all two-letter strings can be thought of as an ordered pair of two letters, where each letter can be selected from the alphabet {a, b, ..., z}.

Since there are 26 letters in the alphabet, there are 26 choices for the first letter in the string. For the second letter, however, there are only 25 choices, since we cannot repeat the letter selected for the first position. Thus, the number of different two-letter strings is the product of the number of choices for each letter, which is 26 * 25 = 650.

This problem illustrates the concept of counting principles, specifically the product rule of counting. The product rule states that the total number of outcomes for a sequence of events is the product of the number of outcomes for each event. In this case, the two events are the selection of the first letter and the selection of the second letter.

The value of tan F in this right-angled triangle is approximately 3.42857.

In the right-angled triangle DEF, with a right angle at E, we are given the length of the perpendicular DE, which is 24 cm, and the length of the base EF, which is 7 cm.

To find the value of tan F, we can use the tangent function, which is defined as the ratio of the length of the opposite side to the length of the adjacent side in a right triangle.

In this case, F is the angle opposite to side DE, and the adjacent side is EF. So, we can write:

tan F = DE / EF

Substituting the given values, we have:

tan F = 24 cm / 7 cm

Now, we can divide 24 by 7:

tan F ≈ 3.42857

So, the value of tan F in this right-angled triangle is approximately 3.42857.

This means that the ratio of the length of the perpendicular side DE to the length of the base side EF is approximately 3.42857. It indicates how steep or inclined the line EF is with respect to the line DE in the triangle DEF.

Remember that tangent is a trigonometric function that relates the angles of a right triangle to the lengths of its sides. In this case, we used it to find the ratio of the sides in the triangle and determine the value of tan F.

In diagram A, the axis of symmetry will be vertical and has rotational asymmetry. In diagram D, the axis of symmetry will be horizontal.

Axial symmetrical is similarity around an axis; an item is internally symmetric if it retains its appearance when turned around an axis.

Rotational symmetry is a property of an object or a figure that remains unchanged when it is rotated about a fixed point by an angle less than 360 degrees.

In diagram A, the axis of symmetry will be vertical and has rotational asymmetry.

In diagram D, the axis of symmetry will be horizontal.

The scenario that the sample means differ more is Scenario 1 because the mean seems to be very far from each other.

The scenario that there is a larger variation in the distribution of data within each sample is Secnario 2

The f statistics is larger for Scenario 1 as the Means are far and the spread is less so the F statistic will be larger.

Scenario 1 as F statistic will be larger. So chances of Rejecting H0 is more.

The F statistic is a statistical measure used to determine if there is a significant difference between the means of two or more groups. It is calculated by dividing the between-group variability (also known as the mean square between) by the within-group variability (also known as the mean square error).

The scenario that there is a larger variation in the distribution of data within each sample is Secnario 2 because for this scenario there seems to be more spread within each sample.

Lastly,  Scenario 1 as F statistic will be larger. So chances of Rejecting H0 is more.
