The fact that black youths are tried as adults more frequently than other races is a statistic. However, without further information such as sample size and significance level, it is difficult to determine the contribution to the test statistic and the p-value.

A larger sample size could potentially increase the test statistic and decrease the p-value, indicating a stronger relationship between race and being tried as an adult. On the other hand, a smaller sample size could result in a weaker relationship and a higher p-value. It is important to consider all relevant factors when interpreting statistics and making conclusions.
This result contributes to the test statistic, which is a numerical value that helps determine if there is a significant difference between the compared groups.

In this case, the test statistic would be larger, indicating a greater difference between the rates of black youths tried as adults and those of other races. A larger test statistic typically leads to a smaller p-value, which is a measure of the probability of observing such a difference by chance alone. A smaller p-value (usually less than 0.05) suggests that the observed difference is not due to chance and is statistically significant, indicating a possible disparity in the treatment of black youths within the justice system.

It is impossible to determine if 443 is a plausible value for the true average degree of polymerization.

The interval you mentioned might provide some information about the possible range of values for the true average degree of polymerization. However, it would depend on how the interval was calculated and what assumptions were made in the calculation.

In general, if the interval was calculated using a reliable and appropriate statistical method, and if the underlying data is representative and unbiased, then it is possible that 443 is a plausible value for the true average degree of polymerization. However, without more information about the context and the data, it is difficult to make any definitive conclusions.

Answer:

9. -4x+19y-7

10. 7x+20

Step-by-step explanation:

9. To simplify this expression, simply combine like terms. Add all of the terms with the x variable together, then the terms with the y variable, then the constant terms. I will show this step by step, but usually you do not have to show this work. The order of the terms does not matter.

x variable terms: (4x-8x)+7y-2+6y+6y-5= -4x+7y-2+6y+6y-5

y variable terms: (7y+6y+6y)-4x-2-5=19y-4x-2-5

constant terms: (-2-5)-4x+19y=-4x+19y-7

10. To simplify this expression, expand all terms and then combine like terms. The first term can be expanded by multiplying each term in the parentheses by 2.

Expand terms: 2(5+3x)+(x+10)= 10+6x+x+10

Now, you can combine like terms as done on the last problem. Note that I got rid of the parentheses in the second term, as they did not matter (since there was no term in front of them).

x variable terms: (6x+x)+10+10=7x+10+10

The required value of x is 125° for the given pentagon.

The external angle of a pentagon is formed by extending one of its sides, and it is supplementary to the adjacent interior angle of the pentagon.

According to the given figure,

We have been given that a pentagon, which has five sides is shown.

As we know that the sum of the external angles of any polygon is always 360 degrees.

So, x° + 40° + 65° + 60° + 70° = 360°

x° + 235° = 360°

x° = 360° - 235°

Apply the subtraction operation, and we get

x = 125°

Therefore, the required value of x is 125°.

To find the points on the curve where the Tangent line is horizontal, we need to find the points where the derivative of the curve is zero.

Let's differentiate the equation of the curve implicitly with respect to x:

2yy' = 2x + 2xy'

Simplifying the equation, we get:

yy' = x + xy'

Now, we can rearrange the equation to isolate y':

yy' - xy' = x

Factoring out y' on the left side:

(y - x)y' = x

Finally, we can solve for y' by dividing both sides by (y - x):

y' = x / (y - x)

For the tangent line to be horizontal, the derivative y' must be zero. Therefore, we set y' = 0:

0 = x / (y - x)

Since the denominator cannot be zero, we have two cases:

Case 1: y - x ≠ 0

In this case, we can divide both sides by (y - x):

0 = x / (y - x)

Cross-multiplying, we get:

0(y - x) = x

0 = x

This means x must be zero. Substituting x = 0 back into the equation of the curve, we can solve for y:

y = x^2 = 0^2 = 0

So, one point on the curve where the tangent line is horizontal is (0, 0).

Case 2: y - x = 0

In this case, y = x. Substituting y = x back into the equation of the curve, we have:

y^2 = x^2

This equation represents the curve y = ±x, which is a pair of lines passing through the origin at a 45-degree angle.

Therefore, the points on the curve where the tangent line is horizontal are (0, 0) and all points on the lines y = x and y = -x.

(a) Without restriction: 153 ways to distribute 6 chocolate bars, 7 licorice sticks, and 12 pixie sticks among 5 trick or treaters. (b) Each child gets a piece of each type of candy: 55 ways to distribute the candies.

(c) Each child gets a piece of each type of candy and the same total number of pieces of candy: 36 ways to distribute the candies.

(a) Without restriction:

We can use the stars and bars method to determine the number of ways to distribute the candies without any restrictions. We need to place two bars between the candies to divide them into five groups. We can represent the candies using stars, and the bars can be placed in any of the 18 spaces between the stars. Therefore, the number of ways to distribute the candies without restriction is: 153

(b) Each child gets a piece of each type of candy:

In this case, we can distribute one chocolate bar, one licorice stick, and two pixie sticks to each child, leaving us with one chocolate bar, two licorice sticks, and two pixie sticks. We can distribute these remaining candies using the stars and bars method. We need to place two bars between the candies to divide them into five groups, but we can only place a bar after the first chocolate bar and after the first licorice stick to ensure that each child gets at least one piece of each type of candy. Therefore, the number of ways to distribute the candies in this case is: 55

(c) Each child gets a piece of each type of candy and the same total number of pieces of candy:

In this case, each child needs to receive 3 pieces of candy, consisting of one chocolate bar, one licorice stick, and one pixie stick. Therefore, we need to distribute 5 chocolate bars, 5 licorice sticks, and 5 pixie sticks among the 5 children. We can use the stars and bars method to determine the number of ways to distribute the candies without restriction. We need to place two bars between the candies to divide them into five groups, but we can only place a bar after the first chocolate bar and after the first licorice stick to ensure that each child gets at least one piece of each type of candy. Therefore, the number of ways to distribute the candies in this case is: 36

Note that this assumes that we are distributing the candies without restriction among the children who must receive the same total number of pieces of candy. If we want to distribute the candies evenly among the children, we can use the stars and bars method with 2 bars to divide the candies into 5 groups, giving us: 120 ways.

Step-by-step explanation:

:-)

The new coordinates of the point (5, 2) after rotating counterclockwise about the origin through an angle of 5 degrees are approximately (4.993, 2.048).

To find the new coordinates of the point (5, 2) after rotating counterclockwise about the origin through an angle of 5 degrees, we can use the rotation formula:

x' = x * cos(theta) - y * sin(theta)

y' = x * sin(theta) + y * cos(theta)

Where (x, y) are the original coordinates, (x', y') are the new coordinates after rotation, and theta is the angle of rotation in radians.

Converting the angle of rotation from degrees to radians:

theta = 5 degrees * (pi/180) ≈ 0.08727 radians

Plugging in the values into the rotation formula:

x' = 5 * cos(0.08727) - 2 * sin(0.08727)

y' = 5 * sin(0.08727) + 2 * cos(0.08727)

Evaluating the trigonometric functions and simplifying:

x' ≈ 4.993

y' ≈ 2.048

The dimensions of the rectangular playing field are:

length = 92 yards and

width = 24 yards.

Given, the perimeter of the rectangular field is : 232 yards.

From the given question, length of the field is 4 yards less than quadruple the width.

hence, let the width of the field be x yards.

Length of the field = 4x - 4 yards.

we know that perimeter of the rectangle = 2(l+w)

therefore, substitute the values in the above formula:

2(4x - 4 + x) = 232

2(5x - 4) = 232

multiply the terms.

10x - 8 = 232

arrange the constants on one side.

10x = 232 + 8

10x = 240

x = 240/10

x = 24

hence we get the width as x = 24 yards.

Now substitute the value of x to find out the value of the length.

therefore, l = 4x - 4

l = 4(24) - 4

l = 96 - 4

l = 92

Therefore length and width of the rectangular field is 92 and 24 yards respectively.

Answer:

The surface area of a right rectangular prism is given by: 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height.

The current surface area of the prism is: 2(6)(5) + 2(6)(10) + 2(5)(10) = 60 + 120 + 100 = 280 cm^2

To double the surface area, we want to find the new height h' such that: 2(6)(5) + 2(6)(h') + 2(5)(h') = 2(280)

Solving for h', we get:

2(6)(5) + 2(6)(h') + 2(5)(h') = 560

2(6)(h') + 2(5)(h') = 560 - 120 = 440

2(11)(h') = 440

h' = 440/22

h' = 20 cm

So the height of the new prism should be 20 cm to double the surface area of the original prism.

Answer:

slope m = - 8

Step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

y + 3 = - 8(x - 4) ← is in point- slope form

with slope m = - 8

The slope is :

Solution:

Given: \(\bf{y+3=-8(x-4)}\)

To determine the slope, it's important to know the form of the equation first.

There are 3 forms that you should be familiar with.

The three forms of equations of a straight line are:

This equation matches point slope perfectly.

The question becomes, how do you work with point slope to find slope?

In point slope, m is the slope and (x₁, y₁) is a point on the line.

Similarly, the slope of \(\bf{y+3=-8(x-4)}\) is -8.
