Answer:

-2

Step-by-step explanation:

Using the slope formula (y1-y2)/(x1-x2), the slope of the line is (-10-8)/(9-0), which is equal to (-18)/9= -2.

Slope of the given coordinates (9,-10) and (0,8) is -2.

In Mathematics, a slope of a line is the change in y coordinate with respect to the change in x coordinate.

The net change in y-coordinate is represented by Δy and the net change in x-coordinate is represented by Δx.

Hence, the change in y-coordinate with respect to the change in x-coordinate is given by,

m = change in y/change in x = Δy/Δx

Where “m” is the slope of a line.

Given, coordinates of the two points,

(x₁ , y₁) = (9, -10)

(x₂ , y₂) = (0, 8)

slope m = (y₂ - y₁)/(x₂ - x₁)

             = (8 - -10)/(0 - 9)

             = (8 + 10)/-9

             = 18/-9

slope m = -2

Hence, -2 is the slope for given coordinates (9,-10) and (0,8).

She wants to pick 10 books and she picks all 4 poetry books and therefore needs to pick 6 more from the 5+5+7=17 other (non-poetry) books.

So she can pick the remaining (non-poetry) books in (17 CHOOSE 6) = 17C6 = 12376 ways.

For each of the 12376 ways to pick the 10 books to read, she can arrange the

In order to calculate a 95% confidence interval for the mean chromatic contrast of crab spiders on daisies, you would need to have the sample mean and standard deviation of the chromatic contrast data.

Additionally, you would need to know the sample size. With this information, you could use a t-distribution or a normal distribution to calculate the confidence interval. Once the confidence interval is calculated, it can be interpreted as a range of values that you can be 95% confident contains the true population mean chromatic contrast of crab spiders on daisies. The confidence interval takes into account both the variability of the data and the sample size, and gives a range of values that is likely to contain the population mean with a certain degree of confidence.

Option 2: AAS is the right answer

Answer:

Question 1: The appropriate measures of center for this data set would be (1) Mean and (2) Median. There is no mode in this data set as there are no repeating values.

Question 2: To find the standard deviation, we first need to find the mean:

Mean = (513 + 490 + 496 + 380 + 490 + 513 + 503 + 513 + 500 + 492) / 10 = 494.0

Next, we find the difference between each data point and the mean:

(513 - 494.0), (490 - 494.0), (496 - 494.0), (380 - 494.0), (490 - 494.0), (513 - 494.0), (503 - 494.0), (513 - 494.0), (500 - 494.0), (492 - 494.0)

19, -4, 2, -114, -4, 19, 9, 19, 6, -2

Then we square each difference:

361, 16, 4, 12996, 16, 361, 81, 361, 36, 4

The sum of these squared differences is:

361 + 16 + 4 + 12996 + 16 + 361 + 81 + 361 + 36 + 4 = 14136

To find the variance, we divide the sum of squared differences by the number of data points minus one:

Variance = 14136 / 9 = 1570.7

Finally, we find the standard deviation by taking the square root of the variance:

Standard deviation = √1570.7 ≈ 39.6 (rounded to the tenths place)

The simplified expression of √12 (-1+√5) is -2√3 + 2√15

The radical expression is given as:

√12 (-1+√5)

Express √12 as 2√3

So, we have:

√12 (-1+√5) = 2√3(-1+√5)

Evaluate the product

√12 (-1+√5) = (-2√3+2√15)

Remove the bracket

√12 (-1+√5) = -2√3 + 2√15

Hence, the simplified expression of √12 (-1+√5) is -2√3 + 2√15

By finding all the four slopes, we can see that the word is ECHA.

We know that the general linear equation can be written as:

y = a*x + b

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

We know that if the line passes through (x₁, y₁) and (x₂, y₂) then the slope is:

s = (y₂ - y₁)/(x₂ - x₁)

With that formula we can get the slopes.

1) Using the points (0, 3) and (2, 4).

m = (4 - 3)/(2 - 0) = 1/2, so the letter is E.

2)Using (-1, -12) and (1, -8)

m = (-8 + 12)/(1 + 1) = 4/2 = 2, so the letter is C.

3) We have (2, -6) and (-4, -3) so:

m = (-3 + 6)/(-4 - 2) = 3/-6 = -1/2, so the letter is H

4)we can use the points (0, 3) and (1, 1), so:

m = (1 - 3)/(1 - 0) = -2, so the letter is A

Then the word is ECHA

The value of x from the logarithmic expression is 4 and -8

Logarithm are inverse of exponential function. Given the logarithmic function below;

log (X) + log (X+4)=log 32

Since positive will become multiplication, hence;

X(X+4) = 32

Expand

X^2 + 4x = 32

x^2 + 4x - 32 = 0
x^2 + 8x - 4x - 32 = 0
x(x + 8) - 4(x + 8) = 0
(x-4)(x+8) = 0
X = 4 and -8

Rounding to two decimal places, the surface area of the cylinder is approximately 123.79 square units.

The formula for the surface area of a cylinder is:

A = \(2πr^2\) + 2πrh

where r is the radius of the base, h is the height, and π is the constant pi.

Plugging in the given values, we get:

A = 2π(2.22)^2 + 2π(2.22)(6.66)

A = 2π(4.9284) + 2π(14.7912)

A = 30.9748 + 92.8184

A = 123.7932

The average rate of change of the function f(x) = √(x+4) over the interval 2 ≤ x ≤ 6 is approximately 0.29 to the nearest hundredth.

To find the average rate of change of the function f(x) = √(x+4) over the interval 2 ≤ x ≤ 6, we need to calculate the change in the function divided by the change in the input variable over that interval.

The change in the function between x = 2 and x = 6 is:

f(6) - f(2) = √(6+4) - √(2+4) = √10 - √6

The change in the input variable between x = 2 and x = 6 is:

6 - 2 = 4

So, the average rate of change of the function over the interval 2 ≤ x ≤ 6 is:

(√10 - √6) / 4

To approximate the answer to the nearest hundredth, we can use a calculator or perform long division to get:

(√10 - √6) / 4 ≈ 0.29
