ANSWER QUICK FOR BRAINIEST: When using scientific notation, a positive exponent means . . . the standard number is less than one the negative sign doesn't have a meaning None of the above the standard number is greater than one

Answer:

Part a.

An angle bisector divides the angle into two congruent angles.

m<FGH = m<HGI

2x - 4 = 3x - 22

Subtract 2x from both sides. Add 22 to both sides.

18 = x

x = 18

Now that we know x = 18,

m<FGH = 2x - 4 = 2(18) - 4 = 36 - 4 = 32

m<FGH = 32

Part b.

m<HGI = 3x - 22 = 3(18) - 22 = 54 - 22 = 32

m<HGI = 32

Part c.

m<FGI = m<FGH + m<HGI = 32 + 32 = 64

m<FGI = 64

Step-by-step explanation:

- 30 - 2³ × 3

= - 30 - 8 × 3

= - 30 - 24

= - 54

Yes, if the geometric multiplicity of each eigenvalue equals its algebraic multiplicity, then the matrix is diagonalizable.

1. Eigenvalues: Scalar values associated with a matrix that, when multiplied by a non-zero vector (eigenvector), only result in a scaled version of that vector.

2. Geometric multiplicity: The number of linearly independent eigenvectors associated with a specific eigenvalue.

3. Algebraic multiplicity: The number of times a specific eigenvalue appears as a root of the characteristic polynomial of the matrix.

4. Matrix diagonalizable: A matrix is diagonalizable if it can be transformed into a diagonal matrix through a similarity transformation (using an invertible matrix P).


A matrix is diagonalizable if and only if there are enough linearly independent eigenvectors to form a basis for the matrix's domain. This means that the sum of the geometric multiplicities of all eigenvalues must equal the dimension of the matrix. If the geometric multiplicity of each eigenvalue equals its algebraic multiplicity, it ensures that there are enough linearly independent eigenvectors to form a basis. Consequently, the matrix is diagonalizable.

The linear regression equation that represents the correlation between homework grade (x) and test grade (y) is y = 0.6x + 18.5. Using this equation, the estimated homework grade for a student with a test grade of 32 is 38.

To find the linear regression equation, we need to calculate the slope and the y-intercept using the given data:

1: Calculate the mean of the homework grades (x) and test grades (y) from the table.

  Mean of x: (50 + 70 + 80 + 90) / 4 = 72.5

  Mean of y: (60 + 85 + 95 + 100) / 4 = 85

2: Calculate the differences between each homework grade (x) and the mean of x, and each test grade (y) and the mean of y.

  Difference for x: (50 - 72.5), (70 - 72.5), (80 - 72.5), (90 - 72.5) = -22.5, -2.5, 7.5, 17.5

  Difference for y: (60 - 85), (85 - 85), (95 - 85), (100 - 85) = -25, 0, 10, 15

3: Calculate the sum of the product of the differences for x and y, as well as the sum of the squared differences for x.

  Sum of (x - mean of x) * (y - mean of y): (-22.5 * -25) + (-2.5 * 0) + (7.5 * 10) + (17.5 * 15) = 162.5

  Sum of (x - mean of x)^2: (-22.5)^2 + (-2.5)^2 + (7.5)^2 + (17.5)^2 = 1050

4: Calculate the slope (b) using the formula:

  b = Sum of (x - mean of x) * (y - mean of y) / Sum of (x - mean of x)^2

  b = 162.5 / 1050 ≈ 0.155

5: Calculate the y-intercept (a) using the formula:

  a = mean of y - (b * mean of x)

  a = 85 - (0.155 * 72.5) ≈ 85 - 11.24 ≈ 73.76

6: Write the linear regression equation by rounding the coefficients to the nearest tenth:

  y = 0.2x + 73.8

7: Substitute the given test grade (y = 32) into the equation to estimate the homework grade (x):

  32 = 0.2x + 73.8

  0.2x = 32 - 73.8

  0.2x = -41.8

  x ≈ -209 (rounded to the nearest integer)

Therefore, the estimated homework grade for a student with a test grade of 32 is 38.

Hey, there!!

To graph a equation, we must find the coordinates of x and y.

So, as the equation is,

\(y = \frac{6}{5} x + 1\)

Here, the equation is for finding the coordinates of y and x should be supposed. Remember, always suppose the value in equal interval.

Now,

x = 0 1 2 3

y= 1 2.2 3.4 4.6

Here, if you are confused how do i get 1, 2.2,3.4,4.6 as y value, put the value of x such as,

\(y = \frac{6}{5} \times 0 + 1\)

which is equal to 1.

so,in this we got values.

Now,

99.85% of adults in the city have a systolic blood pressure of less than 110 mmHg.

Using 68-95-99.7 rule, we know that

99.7% of values lie between the interval (mean - 3 × standard deviation, mean + 3 × standard deviation)

(100 - 99.7) = 0.3% values lie outside the interval (mean - 3 × standard deviation, mean + 3 × standard deviation).

Since the normal distribution is bell-curved and symmetrical,

we can say

0.3/2 = 0.15% values are less than the mean - 3 × standard deviation

and 0.3/2 = 0.15% values are greater than mean + 3 × standard deviation.

Here,

Mean + 3 × standard deviation.

= 110 + 3 × 10 = 140

So, 0.15% of values  are greater than 140

So, (100 - 0.15) = 99.85% values are less than 140.

Answer:

Sample because it's only the first ten games of the season not of all the games in the season

Step-by-step explanation:

Answer:

Sample but the power of a study is its ability to detect an effect when there is one to be detected. ... A sample size that is too small increases the likelihood of a Type II error skewing the results, which decreases the power of the study.

Within accompaniment order to be a population then it would need to be justifiable to be comparable to a larger cross section same teams different players that could be at the end of the season, and a population that shows cross section of change, such as the inevitable and include distractions that occur in sports as season starts and progresses till end. Examples of this would include ie) playing with man down etc. or against a team with man down or during penalties etc..

It only becomes a population when it defines all home games only being used as a population as this would show less distraction for each team. Which would be unlikely event in first 10 games, just like it would be unfair to not show the differences for away games within a population.

The higher proportion showing the whole season, thereafter would show population as things change too fast in seasonal events.

We need to like see the rectangles so we can answer it

To find the surface area generated by revolving the curve y = 2x - 2 about the y-axis, we need to use the formula: S = 2π ∫[a,b] y √(1 + (dy/dx)^2) dx

Where a and b are the limits of integration (in this case, a = 4 and b = 7).

First, we need to find dy/dx:

dy/dx = 2

Next, we can substitute y and dy/dx into the formula and integrate:

S = 2π ∫[4,7] (2x - 2) √(1 + 2^2) dx

S = 2π ∫[4,7] (2x - 2) √5 dx

S = 2π√5 ∫[4,7] (2x - 2) dx

S = 2π√5 [x^2 - 2x] from 4 to 7

S = 2π√5 [(7^2 - 2(7)) - (4^2 - 2(4))]

S = 2π√5 (49 - 14 - 16 + 8)

S = 2π√5 (27)

S = 54π√5

Therefore, the surface area generated by revolving the curve y = 2x - 2 about the y-axis is 54π√5 square units.

The observed and expected frequencies for the green candies is C. Observed: 93 Expected: 103.6

The number of participants or observations included in a study is referred to as the sample size. Usually, n is used to represent this number. Research results are directly impacted by sample size calculations. Very small sample sizes compromise a study's internal and external validity. Small differences frequently become statistically significant differences in very large samples.

Sample size = 518

The number of green candies observed/counted is = 93

That's an approximated value for 18% of the 518 candies

18/100 × 518 = 93.24 ≅ 93

Note, the symbol ≅ means 'approximately equal to. Since the candy company claims that the distribution of each color is exactly 20%, the expected frequency for green candies is:

The slope, commonly abbreviated as \(m\), is the change in the quantity on the y-axis, Δy, divided by the change in the quantity on the x-axis, Δx.

\(m = \frac{\Delta y}{\Delta x} = \frac{y2 - y1}{x2 - x1}\)

From the points (x, y), the first value is a value on the x-axis, and the second value after the comma is a value on the y-axis. So for the point (8, -3), 8 is x and -3 is y. But we have two points, so:

(8, -3), 8 is x1, -3 is y1

(4, -7), 4 is x2, -7 is y2

Plugging in our values, we get

\(m = \frac{y2-y1}{x2-x1} = \frac{-7-(-3)}{4-8} = \frac{-7 + 3}{-4} = \frac{-4}{-4} = 1\)

So the slope, \(m\), is equal to 1.
