Answer:

red ---- 77 degrees

Step-by-step explanation:

Answer:

10

Step-by-step explanation:

First solve for x. HI = 2x, IJ = 4x - 10, and the whole length HJ = 4x.

So 2x + 4x - 10 = 4x.

6x - 10 = 4x

6x - 4x - 10 = 4x - 4x

2x - 10 = 0

2x - 10 + 10 = 0 + 10

2x = 10

x = 5.

IJ is 4x - 10, so it becomes 4(5) - 10

20 - 10 = 10

The Kruskal-Wallis test is a non-parametric test used to compare three or more independent groups to determine if there is a significant difference between the medians of the groups. The test statistic used in this test is denoted by the letter "H," which is calculated based on the ranks of the data.

True. The test statistic calculated in the Kruskal-Wallis test is denoted by the symbol H, not to be confused with the Shapiro-Wilk test statistic denoted by W. The Kruskal-Wallis test is a non-parametric test used to compare the median ranks of three or more independent groups. The test statistic H is calculated by comparing the between-group sum of squares to the total sum of squares. H follows a chi-squared distribution with degrees of freedom equal to the number of groups minus one. The p-value obtained from the chi-squared distribution is used to determine whether to reject or fail to reject the null hypothesis that there is no significant difference between the groups.

The sales tax rate is 8%.

The correct option is (b).

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Jenny bought scrapbooking supplies for $145.00.

She paid $11.60 in sales tax.

let the tax rate be x%.

So, the price without sales tax = 145 - 11.6 = $133.4

Thus, x% of 133.4 = 11.6

133.4 x = 1160

x = 8.65%

x= 8%

Hence, the tax rate is 8%.

Answer:

The length of the third side of the triangle is 30.

Step-by-step explanation:

Here is the formula for the Pythagorean Theorem:

\(a^{2} + b^{2} = c^{2}\)

The hypotenuse, based on the problem, is 50. Anyways, let's get back to calculating!

We need to multiply 40 times 40 and 50 times 50.

40 times 40, or 40 squared, equals to 1600.

50 times 50, or 50 squared, equals to 2500.

\(c^{2} - b^{2} = a^{2}\)

Now, let's subtract. 2500 - 1600 = 900. We need to find the square root of 900--which is 30, because 30 times 30, or 30 squared, equals to 900.

Answer:

30

Step-by-step explanation:

c=√a^2+b^2

a=√c^2-b^2 = √50^2-40^2 = 30

(A.) If a polygon is a pentagon, then it has five angles.

The inverse of the conditional statement "If a polygon has five angles, then it is a pentagon" is "If a polygon does not have five angles, then it is not a pentagon."

Option C is the correct answer.

A pentagon is a polygon that has five sides and five angles.

The sides and angles of a pentagon are not all equal unless it is a regular pentagon.

A regular pentagon has five equal sides and five equal angles.

We have,

The inverse of a conditional statement is formed by negating both the hypothesis and the conclusion.

In this case, we negate the statement "a polygon has five angles" to "a polygon does not have five angles," and negate the statement "it is a pentagon" to "it is not a pentagon."

The vertex of a figure is the point of intersection of two sides of the shape.

The perimeter of the square is given as 12 units, the length of each side of the square is calculated as follows;

P = 12 units

To determine another possible vertex of the square, the length between the points must be equal to 3.

Let's consider point A;

A = (1, 2)

given vertex = (-1, 1)

distance between the points = √ (-1 -1)² + (1 - 2)² = √5

Let's consider point B;

Surface area = 400 ft²

Volume = 448 ft³

length = 4 ft

width = 8 ft

height = 14 ft

The storage chest is a rectangular prism in shape

We use volume of rectangular prism formula:

Hence, the volume of the storage chest is 448ft³

Surface area of rectangular prism = 2(lw + hw + hl)

Surface area = 2(4 × 8 + 14 × 8 + 14 × 4)

Surface area = 2(32 + 112 + 56)

Surface area = 2(200)

Surface area = 400 ft²

Surface area of the chest = 400 ft²

Therefore, the Taylor polynomials T2(x) and T3(x) centered at a=0 for the function f(x) = 25ln(1+x) are:

T2(x) = 25 + 25x - 12.5x^2

T3(x) = 25 + 25x - 12.5x^2 + 16.67x^3

To calculate the Taylor polynomials T2(x) and T3(x) centered at a=0 for the function f(x) = 25ln(1+x), we need to find the derivatives of f(x) and evaluate them at x=0.

First, let's find the derivatives of f(x):

f'(x) = 25/(1+x)

f''(x) = -25/(1+x)^2

f'''(x) = 50/(1+x)^3

Now, let's evaluate these derivatives at x=0:

f'(0) = 25/(1+0) = 25

f''(0) = -25/(1+0)^2 = -25

f'''(0) = 50/(1+0)^3 = 50

Using these values, we can now write the Taylor polynomials:

T2(x) = f(0) + f'(0)x + (f''(0)/2!)x^2 = 25 + 25x - 12.5x^2

T3(x) = f(0) + f'(0)x + (f''(0)/2!)x^2 + (f'''(0)/3!)x^3 = 25 + 25x - 12.5x^2 + (16.67)x^3

The graph of g is Transformation up 7 units.

what is Transformation?

A graph transformation is a method for altering an existing graph or graphed equation to create a different version of the graph that follows. The modification of algebraic equations is a typical form of algebraic issue.

solution:

From the question, we have the following parameters that can be used in our computation:

g(x) = f(x) + k

Also, we have the value of k to be

k = 7

From the question, we can interpret g(x) = f(x) + k as f(x) is shifted up by k units

This means that

g(x) = f(x) + k

So, we have

g(x) = f(x) + 7

When a transversal intersects two parallel lines, it creates eight angles. Among these angles, the alternate interior angles are located on the inside of the parallel lines and on opposite sides of the transversal.

Step-by-step explanation:

Permutations and combinations are mathematical concepts that deal with counting the number of different arrangements or selections of objects from a set.

Permutations:

A permutation is an arrangement of objects in a specific order. For example, consider a set of three letters: A, B, and C. There are 3! = 6 possible permutations of these letters, which are ABC, ACB, BAC, BCA, CAB, and CBA. The notation "3!" is the factorial notation, which means 3 × 2 × 1.

Combinations:

A combination is a selection of objects, where the order does not matter. For example, consider a set of three letters: A, B, and C. There are 3 C 2 = 3 possible combinations of two letters from this set, which are AB, AC, and BC. The notation "3 C 2" is the combination notation, which means the number of ways to choose k objects from a set of n objects.

In summary, permutations deal with the arrangement of objects in a specific order, while combinations deal with the selection of objects without regard to the order.

In order for the longer piece to be 4 feet less than 4 times as long as the shorter piece, he wants to cut it into two pieces.

The length of the longer pieces is then equal to 4x - 4.

The equation then becomes

\(x + 4x - 4 = 11\\ 5x = 11 + 4\\ 5x = 15\\ x = 3 ft\)

The shorter pieces will therefore be 3 feet long.

(b) The conclusion would make if a 0.05 is rejected because the p-value (0.0016) is less than the significance level.

If using a significance level of 0.01, the null hypothesis would still be rejected because the p-value is less than 0.01.

(a) The p-value of 0.0016 indicates that the probability of obtaining a sample mean hemoglobin level of 11.3 g/dl or lower, assuming that the true population mean is 12 g/dl (or higher), is only 0.0016. This suggests that the observed difference between the sample mean and the hypothesized population mean is statistically significant and unlikely to be due to chance alone.

(b) If using a significance level of 0.05, the null hypothesis (that the true population mean is 12 g/dl or higher) would be rejected because the p-value (0.0016) is less than the significance level. Therefore, it can be concluded that the sample provides evidence that the true population mean hemoglobin level is lower than 12 g/dl.

If using a significance level of 0.01, the null hypothesis would still be rejected because the p-value is less than 0.01. In this case, the evidence is even stronger, and the conclusion that the true population mean is lower than 12 g/dl would be even more robust.
