9 more than a number g equals 18

Answer:

FH = 6.0

FG = 3.6

m<H = 31°

Step-by-step explanation:

sin Θ = opp/hyp

cos Θ = adj/hyp

sin 59° = FH/GH

sin 59° = FH/7

FH = 7 × sin 59°

FH = 6.0

cos 59° = FG/GH

cos 59° = FG/7

FG = 7 × cos 59°

FG = 3.6

m<F + m<G + m<H = 180°

90° + 59° + m<H = 180°

m<H = 31°

Step-by-step explanation:

The correct answer is D. (N−2)Σ2/S2.

A chi-square distribution is a probability distribution that arises in statistics, particularly in hypothesis testing and confidence interval estimation. It is defined by its degrees of freedom, which determine the shape of the distribution. In the case of the chi-square distribution, the degrees of freedom are usually denoted by ν (nu).

In the given options, only option D, (N−2)Σ2/S2, corresponds to the formula for calculating the chi-square statistic. Here, N represents the sample size and S represents the sample standard deviation. The numerator, (N−2)Σ2, represents the sum of squared deviations from the mean, adjusted for the degrees of freedom, while the denominator, S2, represents the sample variance.

The chi-square statistic is commonly used in various statistical tests, such as the chi-square test for independence and the chi-square goodness-of-fit test. It follows a chi-square distribution with ν degrees of freedom, where ν is typically equal to N minus the number of parameters being estimated in the statistical model.

Answer:

150 sequences

Step-by-step explanation:

Let's find the sets of 5 integers less than or equal to 6 that could multiply to 300 (where order doesn't matter for right now):

1, 2, 5, 5, 6

1, 3, 4, 5, 5

2, 2, 3, 5, 5

Now let's find the number of unique ways we could reorder these sets

There are \(\frac{5!}{2!} = 60\) ways to order {1, 2, 5, 5, 6}

There are \(\frac{5!}{2!} = 60\) ways to order {1, 3, 4, 5, 5}

There are \(\frac{5!}{2!2!} = 30\) ways to order {2, 2, 3, 5, 5}

There could have, therefore, been 60 + 60 + 30 = 150 different sequences of rolls

Answer:

They did not walk the entire trail.

Step-by-step explanation:

We can first convert 2.4 to a fraction.

(List of decimal places to make the explanation easier to follow)

.0 - tenths

.00 - hundredths

.000 - thousandths

We can split 2.4 into 2+0.4

Start by converting 0.4...

Since the "4" is in the tenths place this means that the fraction would be 4/10.

We can simplify this by dividing 4/10 by 2/2. Notice we can only do this because 2/2 is equivalent to one, so in a sense we are only dividing the fraction by 1.

\(\frac{4/2}{10/2}=\frac{2}{5}\)

Now we add the 2 back on to get...

2 2/5

We can turn it into an improper fraction (multiply the first "large" number by the denominator of the fraction and then add the numerator)

12/5

Now, convert the second fraction...

18/8

We can simplify this by again dividing the fraction by 2/2...

9/4

Now we compare which is greater using the cross multiplication method (numerator of the first fraction multiplied by denominator of the second fraction and numerator of the second fraction multiplied by the denominator of the first fraction):

12*4

9*5

48>45

Therefore 12/5 is greater meaning the hikers did not walk the entire trail

Answer:

Step-by-step explanation:

Let's turn 2 2/8 into decimal.

Now, let's compare both the decimals.

Since 2.4 is greater than 2.25, the two hikers did not complete the entire trail. They were 0.15 miles away to finish.

A corner point, is at (a,b).Then a=band b=a. The absolute minimum of f(x, y) within D is 0,The absolute maximum is 16.

To find the critical point of f(x, y)  to the boundary of D, to consider the boundary curve of D. In this case, the boundary curve is given by the line y = x, where 0 ≤ y ≤ x ≤ 4.

First,  the function f(x, y) in terms of a single variable, either x or y. Let's express it in terms of y:

f(x, y) = x²2 - xy + y²2 - 4x + 4y

Substituting y = x, we have:

f(x, x) = x²2 - x²2 + x²2 - 4x + 4x

= x²2

Now,  to find the critical points of f(x, x) = x²2 within the interval 0 ≤ x ≤ 4. To find the critical points,  differentiate f(x, x) with respect to x and set it equal to zero:

f'(x) = 2x = 0

Solving 2x = 0,  find x = 0. This critical point occurs at the corner point (0, 0), which is not on the boundary curve y = x.

Since there are no critical points of f(x, y) restricted to the boundary curve y = x that are not at a corner point, that there are no critical points (a, b) within the given conditions.

The absolute minimum and maximum of f(x, y) within the region D, to consider the function values at the corners of D.

The corners of D are (0, 0), (4, 0), and (4, 4). Evaluating f(x, y) at these points:

f(0, 0) = 0²2 - 0 × 0 + 0²2 - 4 × 0 + 4 × 0 = 0

f(4, 0) = 4²2 - 4 × 0 + 0²2 - 4 × 4 + 4 ×0 = 0

f(4, 4) = 4²2 - 4 × 4 + 4²2 - 4 ×4 + 4 × 4 = 16

Step-by-step explanation:

Use rise over run to find slope. It is the easiest way to find slope

You rise 5 and 1 to the right

Answer:

The slope is 5

Step-by-step explanation:

So you're just trying to find the slop. We're going to choose 2 points to use which are already marked on the graph.

(0, 2) and (-1, -3)

So to find the slope, we have to find (the difference in y) / (the difference in x)

So we're going to do

The interior angle of the m-gon is ...

  m-interior = 180 -360/m

The exterior angle of the k-gon is ...

  k-exterior = 360/k

The required relationships are ...

  m = 3k

  m-interior = 14/3(k-exterior)

Substituting for m, we can write the latter relation as ...

  (180 -360/(3k)) = 14/3(360/k)

Multiplying by 3k/180, we have ...

  3k -2 = 28

  k = (28 +2)/3 = 10

The values of k and m are 10 and 30, respectively.

For an appropriate use the uniform distribution is to describe a continuous random variable x when relative frequencies of all possible values of x are about the same. So, option(d) is right one.

The uniform distribution is a distribution in which all values are equal. The interval [a,b] of a continuous variable X is said to be divided into one or four parts, meaning that all values in the distribution are equal or equal. If the probability density function equals f(x) = 1/(b−a), x∈[a,b] and is 0 elsewhere, we write X∼U(a,b). A curve is "uniform" when all events have the same probability. That is all occurrences of events have the same frequency. Accordingly, the correct answer is option (c).

a. The table value of z 0.99 is given as 2.58.

b. we use σ = 2.30 minutes.

c. The value of Z is given as 0.609.

d. The confidence interval is (23.391, 24.609) minutes.

a) To find the z-score for a 0.99 confidence interval, we need to find the z-score that leaves 0.5% (since it's two-tailed, we split the 1% or 0.01 of the data that's not within the confidence interval into two) in each tail. The z-score for 0.995 (0.5% in the upper tail) is approximately 2.58 in standard normal distribution tables. So, Z_0.99 is 2.58.

b) Therefore, we use σ = 2.30 minutes.

c) The standard error of the mean (SE) is given by σ/√n, where n is the sample size.

Here, σ = 2.30 minutes and n = 95.

Therefore, SE = σ/√n

= 2.30/√95

= 0.236 minutes.

Multiply this by the z-score to find Z * σ/√n.

Therefore, Z * σ/√n = 2.58 * 0.236 ≈ 0.609.

d) The 0.99 confidence interval for μ

Here, x is the sample mean which is 24 minutes.

So the confidence interval is approximately

= (24 - 0.609, 24 + 0.609)  

= (23.391, 24.609) minutes.

This is the range of values we are 99% confident that the true population mean (μ) falls in.

Yes, if aa is a square matrix and \det(ab^2)=5det(ab 2 )=5, then bb is invertible. This is because if \det(ab^2)=5det(ab 2 )=5, then the determinant of ab is not zero, which means that ab is invertible. Since ab is invertible, this implies that b is also invertible, because if b was not invertible, then ab would not be invertible.

Therefore, bb is invertible as well. Given that A is a square matrix and det(AB^2) = 5, we need to determine if B is invertible. Recall that a matrix is invertible if its determinant is non-zero.Let's first look at the determinant properties:

1. det(AB) = det(A) * det(B)
2. det(B^2) = det(B) * det(B)

Now let's consider the given equation:

det(AB^2) = 5

Substitute the properties mentioned above:

det(A) * det(B) * det(B) = 5

This equation shows that det(A) * det(B)^2 = 5.

Since the determinant of the product is not equal to zero, it means that neither det(A) nor det(B)^2 is equal to zero. Therefore, det(B) must be non-zero as well, because if it were zero, det(B)^2 would also be zero.As a result, since det(B) is non-zero, we can conclude that B is invertible.

An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence. For instance, the common difference in the arithmetic series 3, 9, 15, 21, and 27 is 6.

Arithmetic sequences are sequences containing these patterns. The distance between succeeding terms in an arithmetic series is always the same. The difference between consecutive words is always two, hence the sequence 3, 5, 7, 9... is arithmetic.

An explicit formula that states a = d (n - 1) + c, where d is the common difference between succeeding words, and c = a1, can be used to establish an arithmetic sequence.

The difference in fundraising between incumbents and challengers highlights the significant advantages of incumbency in American politics and the challenges that challengers face in trying to unseat an incumbent candidate.

In the 2020 House races, there was a significant difference in the average amounts raised by incumbents and challengers. According to data from the Center for Responsive Politics, the average amount raised by incumbents was $2.9 million, while the average amount raised by challengers was $676,000.
This discrepancy can largely be attributed to the advantages of incumbency. Incumbent candidates already have established networks of donors and supporters, name recognition, and a record of legislative accomplishments that they can leverage to raise funds. Additionally, incumbents are often able to attract larger donations from political action committees (PACs) and other interest groups who are more likely to support the candidate who already holds the office.
Challengers, on the other hand, often struggle to gain traction in fundraising due to their lack of name recognition and the fact that they are not yet seen as viable candidates. They also face more difficulty in attracting larger donations from PACs and interest groups, as these organizations tend to favor incumbents who are seen as more likely to win.
Overall, the difference in fundraising between incumbents and challengers highlights the significant advantages of incumbency in American politics and the challenges that challengers face in trying to unseat an incumbent candidate.
