What is the answer to this?

Answer:

y = -x + 3

Step-by-step explanation:

Given:

Coordinates are (2, 1) and (6, -3)

y = mx + c

For Coordinate (2, 1)

1 = m(2) + c

1 = 2m + c ........... Eq1

For Coordinate (6, -3)

-3 = m(6) + c

-3 = 6m + c ........... Eq2

From Eq2 - Eq1

6m - 2m = -3 - 1

4m = - 4

m = -1

From eq 1

1 = 2m + c

1 = 2(-1) + c

1 = -2 + c

c = 2 + 1

c = 3

So,

y = mx + c

y = (-1)(x) + 3

y = -x + 3

Answer:

Should be roughly 79.76% if I'm doing this right.

Step-by-step explanation:

Looking at the problem, you're given 3 things:

1) 6.8 million tonnes are recycled;

2) 6.8 million tonnes is 27% of the total household waste;

3) 20.1 million tonnes could be recycled.

Since they're asking for what percentage of total household waste could be recycled, you're looking at a multi-step cross multiplication problem.

It's not very difficult though, don't worry.

So I'm gonna start by telling you to just forget that the word "million" exists for the moment. You only need 6.8, 20.1, and 27%.

Setting up the first part of the problem requires you to convert 27% into a fraction. That's \(\frac{27}{100}\).

6.8 is 27% of some mysterious number that we need to figure out what percent of household waste could be recycled, so that'll be set up on the opposite side of the equal sign as the equivalent to 27.

So we're starting out with this: \(\frac{6.8}{?} =\frac{27}{100}\)

Since you're trying to initially find the total household waste, we're setting x as the variable to solve for.

\(\frac{6.8}{x} =\frac{27}{100}\)

Cross-multiplying** means you multiply the numerator of one side of the equal sign to the denominator of the other side of the equal sign, and vice versa (denominator of one side to numerator of other). So multiply 6.8 to 100, and 27 to x.

\(680=27x\)

Now that you have this, you have to isolate x. Divide both sides by 27 to do this.

\(25.185185...=x\)

I'm gonna round that for simplicity's sake, because 185 repeats.

\(25.2=x\)

So we have 25.2 million tonnes of total household waste. Great! Now we can find the percentage of household waste that could be recycled.

Since we have how much could be recycled and the total, we just need to solve for the percent this time. So this is what the set-up will look like:

\(\frac{20.1}{25.2} =\frac{x}{100}\)

x being the percent we're solving for.

Cross-multiply again:

\(2010=25.2x\)

Divide both sides by 25.2:

\(79.761904761904...=x\)

Then round for simplicity's sake:

\(79.76=x\)

And you get 79.76% of household waste could be recycled.

Hope this helped!

Answer:

Should be roughly 79.76% if I'm doing this right.

Step-by-step explanation:

Looking at the problem, you're given 3 things:

2) 6.8 million tonnes is 27% of the total household waste;

3) 20.1 million tonnes could be recycled.

The limit as x approaches one is infinity.

\(lim_{x\to1}\frac{x + x {}^{2} + {x}^{3} + ... + {x}^{100} - 1000}{1 - x} =\infty\)

The limit of a function, f(x) as x approaches a given value b, is define as the value that the function f(x) attains as the variable x approaches the given value b.

From the given question, as x approaches 1,

substituting x into 1 - x,

the denominator of the function approaches zero, because 1 - 1 = 0 and thus the function becomes more and more arbitrarily large.

Thus, the limit of the function as x approaches 1 is infinity.

Therefore,

The limit (as x approaches 1)

\(lim_{x\to1}\frac{x + x {}^{2} + {x}^{3} + ... + {x}^{100} - 1000}{1 - x} = \infty \)

The stage of group development that is characterized by disagreements and conflicts is called storming. During this stage, group members may have different ideas and opinions about how to approach tasks and goals, and they may struggle to find a common understanding.

Conflict can arise as individuals compete for leadership roles or try to assert their ideas over others. However, this stage is important for groups to progress towards their goals as it allows for open communication and the airing of different perspectives. Eventually, through negotiation and compromise, groups move on to the norming stage where a common understanding is established and roles are defined. From there, groups move on to performing, where they are able to work together effectively towards their goals.

Finally, the adjourning stage is where the group disbands after reaching their goals or completing their tasks.

The angle, its complement, and its supplement are 36, 54 and 144 degrees respectively

The sum of complementary angles s 90 degrees while that of supplementary angles is 180 degrees.

Let the complement of an angle be 90 -x and its supplement be 180 -x

If three times the measure of a supplement of an angle is eight times the measure of a complement of the angle, then;

3(180-x) = 8(90-x)

Expand

540-3x = 730 - 8x

540-720 = -8x + 3x

180 = 5x

x = 180/5

x = 36 degrees

If V1 and V2 are parallel, their direction vectors will be proportional. the line passing through (-4, -6, 1) and (-2, 0, -3) is not parallel to the line passing through (6, 7, 16) and (5, 4, 18).

To find the direction vector V1 for the line passing through (-4, -6, 1) and (-2, 0, -3), we subtract the coordinates of the two points:

V1 = (-2, 0, -3) - (-4, -6, 1) = (-2 - (-4), 0 - (-6), -3 - 1) = (2, 6, -4)

Similarly, for the line passing through (6, 7, 16) and (5, 4, 18), we subtract the coordinates:

V2 = (5, 4, 18) - (6, 7, 16) = (5 - 6, 4 - 7, 18 - 16) = (-1, -3, 2)

To determine if V1 and V2 are parallel, we check if their components are proportional. In this case, the components are not proportional since (2/(-1)) is not equal to (6/(-3)) or (-4/2). Therefore, V1 and V2 are not parallel.

In conclusion, the line passing through (-4, -6, 1) and (-2, 0, -3) is not parallel to the line passing through (6, 7, 16) and (5, 4, 18).

The standard deviation of the distribution of means is generally smaller than the standard deviation of the population of individuals.

The standard deviation mathematical and statistical analysis tool used to explain the diversity of treatments or values around the Mean is the standard deviation, which is also known as the square root of variance.

The population of individuals is always smaller than the entire population, therefore the possibilities for variances will be lower with the sample than with the population. The higher the population, the greater the chances for deviation from the mean.

Therefore, the standard deviation of the distribution of means is generally smaller than the standard deviation of the population of individuals.

According to the evidence from graph a and graph b, graph a indicates that the model for the data was a good fit because it is a random.

Hence, the correct option is B.

Based on graph a, the residual plot shows a random scattering of points around the horizontal line at y=0. This indicates that the residuals (the differences between the observed and predicted values) are distributed randomly and do not show any clear pattern. This suggests that the data points are evenly distributed around the regression line, indicating a good fit for a linear regression model.

On the other hand, graph b shows a residual plot with a clear pattern or trend. The residuals are not randomly scattered, but instead show a curved pattern or a fan-like shape. This indicates that the model used to fit the data may not be appropriate, as it is not capturing the underlying relationship between the variables accurately.

Hence, the correct option is B.

The Bell Curve is a symmetrical curve that represents the probability distribution of a random variable.

The Bell Curve, also known as the normal distribution or Gaussian distribution, is a statistical concept used to describe the distribution of a set of data. The Bell Curve is a symmetrical curve that represents the probability distribution of a random variable.

The Bell Curve is often used to describe the distribution of scores on a test or exam. In this context, the Bell Curve is used to represent the distribution of scores across a population. The mean score (average score) is represented by the highest point on the curve, and the standard deviation is represented by the width of the curve.

In terms of percentages, the Bell Curve can be divided into different standard deviations, with each standard deviation representing a certain percentage of the population. The percentages of the population within each standard deviation are as follows:

68.27% of the population falls within one standard deviation of the mean.

95.45% of the population falls within two standard deviations of the mean.

99.73% of the population falls within three standard deviations of the mean.

These percentages are useful for understanding how scores or data are distributed across a population and can be used to set cutoff scores or define performance categories.

Step-by-step explanation:

If two lines are parallel, then they have an equal value of slope

Mathematically we can generally have the equation of a line written as;

y = mx + c

where m

is slope and c is the y-intercept

In the case of the equation given, the slope of the line is -2

So technically, we want to get the equation of a line that has a slope of -2 and it passes through (2,-7)

The point-slope form can be written as;

y-y1 = m(x-x1)

So the equation we want to get is;
