Step-by-step explanation:

y-intercept is when x equals 0

The equation of the line that passes through the points (-8, 9) and (2, -6) is y = (-3 / 2)x - 3.Given two points (-8, 9) and (2, -6). We are supposed to find the equation of the line that passes through these two points.

We can find the equation of a line that passes through two given points, using the slope-intercept form of the equation of a line. The slope-intercept form of the equation of a line is given by, y = mx + b,Where m is the slope of the line and b is the y-intercept.To find the slope of the line passing through the given points, we can use the slope formula: m = (y2 - y1) / (x2 - x1).Here, x1 = -8, y1 = 9, x2 = 2 and y2 = -6.

Hence, we can substitute these values to find the slope.m = (-6 - 9) / (2 - (-8))m = (-6 - 9) / (2 + 8)m = -15 / 10m = -3 / 2Hence, the slope of the line passing through the points (-8, 9) and (2, -6) is -3 / 2.

Now, using the point-slope form of the equation of a line, we can find the equation of the line that passes through the point (-8, 9) and has a slope of -3 / 2.

The point-slope form of the equation of a line is given by,y - y1 = m(x - x1)Here, x1 = -8, y1 = 9 and m = -3 / 2.

Hence, we can substitute these values to find the equation of the line.y - 9 = (-3 / 2)(x - (-8))y - 9 = (-3 / 2)(x + 8)y - 9 = (-3 / 2)x - 12y = (-3 / 2)x - 12 + 9y = (-3 / 2)x - 3.

Therefore, the equation of the line that passes through the points (-8, 9) and (2, -6) is y = (-3 / 2)x - 3. Thus, the answer is (-3/2)x - 3.

You are correct, two unit vectors orthogonal to both 9, 4, 1 and -1, 1, 0 are (1/√17, -1/√17, 13/√17) and (-1/√17, 1/√17, -13/√17).

Hello! The two unit vectors orthogonal to both 9, 4, 1 and -1, 1, 0 are (1/√17, -1/√17, 13/√17) and (-1/√17, 1/√17, -13/√17). To find these vectors, we can use the cross product of two vectors, which will give us a third vector that is orthogonal to both vectors. We can find the cross product of the two vectors by multiplying their components together, and use the resulting vector as our new vector.

To find the unit vector, we can divide all of the components of the vector by its magnitude. The magnitude of the vector (1/√17, -1/√17, 13/√17) is 17, so the unit vector is (1/√17, -1/√17, 13/√17).

The other unit vector is the negative of this vector, which is (-1/√17, 1/√17, -13/√17).

Answer: No triangle lengths have to add all three length together to equal 180 like 60 60 60 or 90 80 10

Step-by-step explanation:

The image after the dilation is A' (-2,2) and (4,4)

Here, we have a pre-image with the endpoints A(-4,4) and B(8,8) and we want to find the image after dilation using the scale factor

To find its image after a dilation, we simply multiply the scale factor with each number on the coordinate

Thus, we have

A' as (-2,2) and B' as (4,4)

To plot the image, we can locate these coordinates and join them together and label them as A' and B'

The subpopulations that should receive the test are those with the highest incidence of the condition or disease being tested for, as well as those with a high probability of the condition.

This is because predictive value of a positive test is greater in these subpopulations.

Predictive tests are genetic tests that identify mutations associated with disease or other health conditions that have not yet emerged. They are available for a variety of diseases and conditions, including some types of cancer, heart disease, and dementia.

Predictive testing is used to help people understand their chances of developing a disease and make informed decisions about their health care.

For example, it may help them decide whether to undergo surgery or other preventive measures to reduce their risk.

Predictive testing may be performed for a variety of reasons, including personal curiosity, to inform reproductive decisions, to clarify diagnosis, and to guide treatment choices. Because the results of predictive tests can have significant implications for individuals and their families, the decision to undergo testing should be carefully considered and discussed with a healthcare provider.

B is correct.

Therefore, the equation of the line passing through (-3, -5) and parallel to the line 2x + 3y = 15, in slope-intercept form, is y = (-2/3)x - 7.

To find the equation of a line parallel to the line 2x + 3y = 15 and passing through the point (-3, -5), we need to determine the slope of the given line and use it to construct the equation in slope-intercept form (y = mx + b).

The given line is in the form Ax + By = C, where A = 2, B = 3, and C = 15. To find the slope of this line, we can rearrange the equation to isolate y:

2x + 3y = 15

3y = -2x + 15

y = (-2/3)x + 5

The slope of the given line is -2/3.

Since the line we want to find is parallel to this line, it will have the same slope. Therefore, the slope of the line passing through (-3, -5) will also be -2/3.

Now, we can use the point-slope form of a linear equation to write the equation of the line:

y - y1 = m(x - x1)

Substituting the values of (-3, -5) and -2/3 for (x1, y1) and m, respectively:

y - (-5) = (-2/3)(x - (-3))

y + 5 = (-2/3)(x + 3)

To convert this equation into slope-intercept form, we can simplify and rearrange:

y + 5 = (-2/3)x - 2

y = (-2/3)x - 2 - 5

y = (-2/3)x - 7

Answer:

P(2 red in 5 offspring) = 26.4%

P(no more than 2 red flowers) = 65.9%

Step-by-step explanation:

P(red) = 25%

P(white) = 75%

P(2 red in 5 offspring) = 5C2 P(red)*P(red)*P(white)*P(white)*P(white)

P(no more than 2 red flowers) = P(1 red in 5 offspring) + P(2 red in 5 offspring)

= 5C1 P(red)*P(white)^4 + 0.2637

= 5 * 0.25 * 0.75* 0.75 * 0.75 * 0.75 + 0.2637

You divide distance by time. (miles/hour)

The polar equation for the orbit of Halley's comet is r = (18.09 AU)/(1 + 0.97*cos(theta)), where r represents the distance from the sun to the comet, and theta represents the angle between the major axis of the ellipse and the line connecting the sun and the comet.

The maximum distance from the comet to the sun occurs when theta is equal to 0 or 180 degrees, resulting in r = 36.18 AU.

To derive the polar equation, we start with the general equation for an ellipse in polar coordinates: r = (a*(1 - e²))/(1 + e*cos(theta)), where a is the semi-major axis and e is the eccentricity.

Given that the major axis of Halley's comet is 36.18 AU and the eccentricity is 0.97, we can substitute these values into the equation to obtain r = (18.09 AU)/(1 + 0.97*cos(theta)).

This equation represents the polar equation for Halley's comet.

The maximum distance from the comet to the sun occurs when the cosine term is equal to -1, resulting in r = 36.18 AU.

According to the cohort study, it is a good approximation of the RR in a particular study depends on various factors, including the incidence of the outcome, the size of the exposed and unexposed groups, and the study design. (option d).

The study you mentioned is a prospective cohort study that followed marijuana users and non-users to determine their first experience of a psychotic episode. The table below shows the data collected from the 2-year cohort study.

The OR for developing a psychotic episode in marijuana users compared to non-users can be calculated as follows:

OR = (20/480) / (5/500) = 8.33

This means that marijuana users are 8.33 times more likely to experience a psychotic episode than non-users. However, the OR is not the same as the RR, which measures the distance between the incidence of an outcome in the exposed group compared to the unexposed group.

In this study, the RR can be calculated as:

RR = (20/500) / (5/500) = 4

This means that marijuana users are four times more likely to experience a psychotic episode than non-users. As you can see, the OR and RR are different measures of the distance between the incidence of an outcome in the exposed and unexposed groups. However, in some situations, the OR can be a good approximation of the RR, especially when the incidence of the outcome is low.

Michael needs to analyze the population data, demographics of the city, and the competition in the area to determine whether or not to open a new store.

Michael is trying to determine where to open two new store locations. He has population data to determine the amount of revenue he will receive for each location.

He is charged a $1000 fee for opening a new store at a certain location. However, he is unsure whether the population of the city would be large enough to warrant opening a new store at that location.

The first step that Michael needs to take is to analyze the population data that he has.

Based on the population data, he needs to make an informed decision about whether or not to open a new store at that location. This would require him to take into consideration the average income of the population as well as the demographics of the city.

Another important factor that Michael needs to take into consideration is the competition in the area. If there are already several stores in the area, then opening a new store might not be a good idea.

This is because the competition would be too high and he would not be able to generate enough revenue to make up for the cost of opening a new store.

However, if there are no stores in the area, then Michael might consider opening a new store. This would require him to invest a significant amount of money, but he could also generate a significant amount of revenue in return.

Additionally, he needs to take into consideration the cost of opening a new store and whether or not he can generate enough revenue to make up for that cost.

Overall, Michael needs to carefully analyze all the data that he has before making an informed decision about where to open new store locations.

In conclusion, Michael needs to analyze the population data, demographics of the city, and the competition in the area to determine whether or not to open a new store. If the population is large enough and there is no competition in the area, then he should consider opening a new store. However, if there is already a significant amount of competition in the area, then he should avoid opening a new store.

0 Remainder

Step-by-step explanation:

Step 1:

Start by setting it up with the divisor 8 on the left side and the dividend 40 on the right side like this:

   8 ⟌ 4 0  

Step 2:

The divisor (8) goes into the first digit of the dividend (4), 0 time(s). Therefore, put 0 on top:

       0    

   8 ⟌ 4 0  

Step 3:

Multiply the divisor by the result in the previous step (8 x 0 = 0) and write that answer below the dividend.

       0    

   8 ⟌ 4 0  

       0    

Step 4:

Subtract the result in the previous step from the first digit of the dividend (4 - 0 = 4) and write the answer below.

       0    

   8 ⟌ 4 0  

     - 0    

       4    

Step 5:

Move down the 2nd digit of the dividend (0) like this:

       0    

   8 ⟌ 4 0  

     - 0    

       4 0  

Step 6:

The divisor (8) goes into the bottom number (40), 5 time(s). Therefore, put 5 on top:

       0 5  

   8 ⟌ 4 0  

     - 0    

       4 0  

Step 7:

Multiply the divisor by the result in the previous step (8 x 5 = 40) and write that answer at the bottom:

       0 5  

   8 ⟌ 4 0  

     - 0    

       4 0  

      4 0  

Step 8:

Subtract the result in the previous step from the number written above it. (40 - 40 = 0) and write the answer at the bottom.

       0 5  

   8 ⟌ 4 0  

     - 0    

       4 0  

     - 4 0  

         0  

You are done, because there are no more digits to move down from the dividend.

The answer is the top number and the remainder is the bottom number.

Therefore, the answer to 40 divided by 8 calculated using Long Division is:
