To complete the square for the quadratic equation x²+8x-35=0, we need to add a constant to both sides of the equation that will result in a perfect square trinomial on the left-hand side.

To do this, we need to take half of the coefficient of x, square it, and add it to both sides of the equation. The coefficient of x in this equation is 8, so we take half of 8, which is 4, square it, which is 16, and add it to both sides of the equation:

x² + 8x - 35 + 16 = 16

x² + 8x + 16 = 51

On the left-hand side, we have a perfect square trinomial that can be factored as (x+4)². So, we have:

(x+4)² = 51

To solve for x, we take the square root of both sides:

x+4 = ±√51

Finally, we isolate x by subtracting 4 from both sides:

x = -4 ± √51

Therefore, the number that had to be added to "complete the square" is 16.

If 10p equals 2, then p would equal 0.2

Answer:

Step-by-step explanation:

Start by isolating the variable (in this case, "p") on one side of the equation. To do this, divide both sides of the equation by 10:

10p/10 = 2/10

Simplify both sides of the equation:

p = 0.2

So the solution is p = 0.2.

It is more likely that Ryan planted a yellow bulb and then a white bulb than planted a red bulb and then another red bulb. The probability of planting a yellow bulb and then a white bulb is 0.3905, which is higher than the probability of planting two red bulbs in a row, which is 0.345.

How to solve probability?

To determine which scenario is more likely, we need to calculate the probability of each outcome. Let's start by calculating the probability of planting two red bulbs in a row.

The probability of selecting a red bulb from the first bag is 8/20, from the second bag is 11/20, and from the third bag is 2/20. Thus, the probability of selecting two red bulbs in a row is:

(8/20) * (11/20) + (8/20) * (2/20) + (11/20) * (2/20) = 0.345

Now, let's calculate the probability of planting a yellow bulb and then a white bulb.

The probability of selecting a yellow bulb from the first bag is 7/20, from the second bag is 3/20, and from the third bag is 13/20. The probability of selecting a white bulb from the first bag is 5/20, from the second bag is 6/20, and from the third bag is 5/20. Thus, the probability of selecting a yellow bulb and then a white bulb is:

(7/20) * (5/20) + (7/20) * (6/20) + (3/20) * (5/20) + (3/20) * (6/20) + (13/20) * (5/20) + (13/20) * (6/20) = 0.3905

Therefore, it is more likely that Ryan planted a yellow bulb and then a white bulb than planted a red bulb and then another red bulb. The probability of planting a yellow bulb and then a white bulb is 0.3905, which is higher than the probability of planting two red bulbs in a row, which is 0.345.

What is the midpoint formula?

The midpoint formula is a mathematical formula used to find the midpoint between two given points in a coordinate plane. The midpoint is the exact middle point between the two given points, which is equidistant from each point. The formula for finding the midpoint is:

Midpoint = ( (x1 + x2) / 2, (y1 + y2) / 2 )

To find the endpoints of a diameter, we need to find the midpoint of the diameter first.

The midpoint formula is:

Midpoint = ((x1 + x2)/2, (y1 + y2)/2)

Using the given points, we have:

Midpoint = ((2 + (-18))/2, (7 + 1)/2)

Midpoint = (-8, 4)

Now that we have the midpoint, we can find the endpoints of the diameter by reflecting one of the points across the midpoint.

Let's reflect the point (2, 7):

Endpoint 1 = (2, 7) → ( -8 - (2), 4 - 7)

Endpoint 1 = (-10, -3)

Therefore, the endpoints of the diameter are (-10, -3) and (-18, 1).

To use the large sample z-test for a difference in two proportions, assumptions that must be met include having independent samples, a large sample size, and success-failure conditions must be met.

In order to use the large sample z-test for a difference in two proportions, the following assumptions must be met:

The sample is random and each observation is independent. The sample size for each group is large enough such that both np and n(1-p) are greater than or equal to 10, where n is the sample size and p is the proportion of success.

The two groups being compared are independent of each other. The data is binomially distributed, meaning each observation is either a success or a failure. The populations from which the samples are drawn have similar variances.

If these assumptions are met, the large sample z-test can be used to test the null hypothesis that there is no difference between the two proportions.

Player B is the most consistent, with an IQR of 2. This means that 50% of their scores fell within the range of 3 to 5.

What is probability?

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to happen

To determine which player was more consistent, we need to find the best measure of variability for the data. The two common measures of variability are range and interquartile range (IQR).

The range is the difference between the highest and lowest values in the data set. For Player A, the range is 6 - 1 = 5, and for Player B, the range is 11 - 1 = 10.

The interquartile range (IQR) is a measure of dispersion based on dividing the data into quartiles. It is calculated as the difference between the third quartile (Q3) and the first quartile (Q1).

To find the IQR for each player, we first need to find the quartiles.

For Player A:

Arrange the data in order: 1, 1, 2, 2, 2, 3, 3, 3, 6

Find Q1: (2 + 2) / 2 = 2

Find Q3: (3 + 3) / 2 = 3

Calculate IQR: Q3 - Q1 = 3 - 2 = 1

For Player B:

Arrange the data in order: 1, 1, 2, 4, 4, 5, 5, 5, 11

Find Q1: (2 + 4) / 2 = 3

Find Q3: (5 + 5) / 2 = 5

Calculate IQR: Q3 - Q1 = 5 - 3 = 2

Therefore, Player B is the most consistent, with an IQR of 2. This means that 50% of their scores fell within the range of 3 to 5. In contrast, Player A has an IQR of 1, indicating that 50% of their scores fell within the range of 2 to 3.

Therefore, we can conclude that Player B was more consistent than Player A.

Required number of four letters are 120.

What are letters?

Letters are symbols that represent sounds or phonemes in a language. They are used to form words and written communication. The letters of the alphabet are the basic units of written language, and each language has its own set of letters that represent its sounds. In many languages, the letters are organized into an alphabet, which is a standardized order of the letters used for writing. The letters can be written in uppercase or lowercase form, and they may have different shapes or styles depending on the font used. In addition to the letters of the alphabet, there are also other types of symbols used in written communication, such as punctuation marks, numerals, and special characters.

The given word "MIRAGE" has six letters, and we need to form a four-letter code word using these letters such that the second-to-last letter is a vowel and no letter is repeated.

There are two vowels in "MIRAGE" - "I" and "A". We can choose one of these two vowels to be the second-to-last letter in the four-letter code word. Once we have chosen the vowel, we can choose any one of the remaining five letters for the last letter in the code word, since no letter can be repeated.

After choosing the second-to-last and last letters, we have two letters left to choose for the first two positions in the code word. Since no letter can be repeated, we have four choices for the first letter, and three choices for the second letter.

Thus, the total number of four-letter code words that can be formed from the letters in the word "MIRAGE" if no letter is repeated, and the second-to-last letter must be a vowel is 2 (choices for the second-to-last letter) x 5 (choices for the last letter) x 4 (choices for the first letter) x 3 (choices for the second letter)

= 2 x 5 x 4 x 3

= 120

Therefore, there are 120 four-letter code words that can be formed from the letters in the word "MIRAGE" if no letter is repeated, and the second-to-last letter must be a vowel.

Answer: First, we need to convert Brayden's height to inches, since the diameter of the loop is given in inches.

5 feet 9 inches = (5 x 12) + 9 = 69 inches

Next, we can find the diameter of the loop:

Diameter = 1.5 x 69 inches = 103.5 inches

Finally, we can find the circumference of the loop using the formula:

Circumference = П x Diameter

Circumference = 3.14 x 103.5 inches

Circumference = 325.29 inches

To convert to feet, we divide by 12:

Circumference = 27.11 feet (rounded to two decimal places)

Middle Segment of a Triangle:

Triangles are geometric figures with three sides and three internal angles. We can find different types of lines inside a triangle; one of them is the middle segment. The middle segment of a triangle is a line parallel to one of the sides and bisecting the other two sides. Let L be the line of the middle segment and AC the side parallel to the line L, then the formula of the middle segment is:

L = AC/2

We are given a diagram:

Our objective is to find the missing length of RQ.

We can see that the RQ line divides the ST and UT lines in equal parts. Moreover, the SU and RQ lines are parallel; therefore, we can conclude that the RQ line is the middle segment of the STU triangle. So:

RQ = SQ/2

→2x+2 = (5x-10)/2

→2(2x+2) = 5x-10

The scores of both groups are skewed, so the median and standard deviation are the best measures for comparison. Option D is correct.

In comparing the test scores of two groups, it is important to choose appropriate measures of center and variation to accurately represent the data. If both distributions are nearly symmetric, the mean and standard deviation are commonly used.

However, if the distributions are skewed, it is better to use the median and standard deviation as measures. In this particular case, the scores of Group B are skewed right, which means that the mean may not be a reliable measure of center. Instead, the median should be used. The range is not a good measure of variation for skewed data because it is sensitive to extreme values, so the standard deviation is more appropriate. Hence, option D is answer.

Step-by-step explanation:

the measure of a tangent- tangent angle is half the difference of the measures of the intercepted arcs.

the sum of the arcs in a circle = 360° , then

minor arc FH = 360 - 17x

Then

[tex]\frac{1}{2}[/tex] (17x - (360 - 17x) ) = 75 ( multiply both sides by 2 to clear the fraction )

17x - (360 - 17x) = 150

17x - 360 + 17x = 150

34x - 360 = 150 ( add 360 to both sides )

34x = 510 ( divide both sides by 34 )

x = 15

The measure of angle x of the circle is x = 15

A circle is a closed figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The circumference of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle.

The equation of circle is ( x - h )² + ( y - k )² = r²

For a unit circle , the radius r = 1

x² + y² = r² be equation (1)

Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )

Given data ,

Let the measure of the tangent-tangent angle be = 17x°

Now , the angle created by two tangents in a circle that intersect outside the circle is known as the tangent-tangent angle. This angle's dimension is half the difference between the dimensions of the two intercepted arcs.

So , ( 1/2 ) (17x - (360 - 17x) ) = 75

Multiply by 2 on both sides , we get

(17x - (360 - 17x) = 150

34x = 510

Divide by 34 on both sides , we get

x = 15

=> S = l² + 2lh

where S is the surface area, h is the height of the pyramid, and l is the length of one edge of the square base.

=> l² = 13² = 169

We also know that the pyramid's surface area is 741 square feet, so we can construct the following equation:

=> 741 = 169 + 2(13)(x)

When we condense the right half, we obtain:
