Answer:  

1. y = mx + b

Step-by-step explanation:

y = mx + b

2) to find the y intercept you need to see what cross | ( 8,5)

3) 5 = m(8) = b

4) your slope is negative form the why it pointing

5) in this case your slope is 1/3

6) so now you can do your first step now that you have your (y,x) and slope (your solving for (b)

7)

5 = 1/3 (8) + b

5 = 2.6 + b

5 = 2.6

-2.6

2.4 = b

Answer:

Step-by-step explanation:

Let's use the two noted points for the calculation of slope:

Point 1:  (2,8) and

Point 2: (6,4)

These become our (x1,y1) and (x2,y2).

------------------

We are trying to find a straight line equation of the form y = mx+b, where m is the slope and b is the y-intercept (the value of y when x = 0).

The slope:

m = (y2 - y1)/(x2 - x1)

m = (4 - 8)/(6 - 2)

m = -4/4

m = -1

This gives us y = -1x + b

-----

Find b by entering either of the two given points.  I'll use (6,4):

y = -1x + b  

4 = -1(6) + b

b = 10

The equation is now y = -x + 10

--------

Find the value of y when x = 9:

y = -x + 10

y(9) = -(9) + 10

y(9) = 1

===========

This graph has a negative trend.  Y decreases as x increases.  It crosses the y axis at 10 when x is 0, and is only positive when x < 10.  See the attached graph.  Note that the graph of this line does not intersect many of the points on the original graph.  They fall to either side, and are not consistent with a single line equation.  The general, negative trend of slope - 1 trend holds true, however, so one might conclude errors may have been made in collecting the data.  That is clearly due to your lab partner.  [Well, you might try a better explanation].  A craftier person might calculate a standard deviation of error for the line, but that's next semester.  It is worthwhile noting that a selection of two points other than the ones chosen above for calculating slope, would result in different equations.  We selected the two points used here ((2,8) and (6,4)) because they are clearly noted on the chart.

To find the distance between Basti and Cian, we can use the law of sines in triangle ABC. The law of sines states that the ratio of the length of a side to the sine of the opposite angle is constant for all sides and their corresponding angles in a triangle.

Let's label the distance between Basti and Cian as "x". We know that the measure of angle ABC is 50 degrees and the measure of angle BAC is 60 degrees. We also know that Ali is exactly 150 ft away from Basti.

Using the law of sines, we can set up the following equation:

sin(50°) / 150 = sin(60°) / x

To solve for "x", we can rearrange the equation:

x = (150 * sin(60°)) / sin(50°)

Using a calculator, we can evaluate the expression:

x ≈ (150 * 0.866) / 0.766

x ≈ 168.4 ft

Therefore, the distance between Basti and Cian is approximately 168.4 ft.

X= 30

Y=28

Step-by-step explanation:

It's a right-angle triangle. So, 3 x 30 will give you a 90 degree angle.

180-90=90

That means the next 2 angles should add to 90.

2x28=56

56+34=90

Thus, the amount of loan taken by Shaun on that compounded yearly is found to be: $3105.59.

When interest is paid on top of the principal loaned or invested, compound interest results, and the interest rate is then applied to the new, bigger principal. In essence, exponential growth is produced by interest on interest.

Compounding can work in your favour as your investments and savings accumulate over time, or it might work on you if you're trying to pay off debt.

The formula for compound interest is:

A= P\((1 + r/n)^{nt}\)

For the given question:

A = Amount after compounding $5000.

r = interest = 10%,

t = time 5 years.

P = principal

Put the values:

5000 = P \((1 + 0.10/1)^{1*5}\)

P = 5000/ 1.61

P = 3105.59

Thus, the amount of loan taken by Shaun on that compounded yearly is found to be: $3105.59.

According to the statement, the Ship must move at an average pace of 150 meters per hour.

The variable under examination is lessened when the gradient is "downhill" (negative). When used as a gauge of how well things are doing, "downhill" denotes a downward trend. Yet, if this indicates trouble or some other unpleasant quality, the situation is improving.

The chess player Carissa walks very, very slowly. She actually moves at speeds of 100 meters per hr upward, 150 meters per hr on flat terrain, and 200 meters every hour on downhill terrain.

Here,

Carissa traverses Boston on foot from a coffeehouse to a boba store before returning over the same path.

Total distance walked = 2 [200 + 100 + 150] = 900 meter

Total time = 2 [1 + 1 + 1] = 6 hour

Average speed is calculated as distance divided by time (900 / 6 = 150 m/s),

As a result, the needed Carissa average speed is 150 meters per hr.

We have the function:

a. Zeros of the function

By definition, the zeros are the values of t such that f(t) = 0. In this case, we have:

Rewriting the function, we have:

So the zeros of the function are:

b. Meaning of the zeros

The function y = f(t) represents the height of the ball at time t.

• So the zeros are the times at which the function reaches a height equal to zero.

• We see that one zero is positive and the other negative. Only the positive zero (t = 2) is meaningful because the negative (t = -1/6) represents a negative value of time!

c. Initial height

The ball is thrown at time t = 0. The height of the ball at time t = 0 is:

So the ball is thrown from a height of 6 feet.

Answer

• a., The zeros are t = -1/6 and t = 2.

• b., The zeros are the values of time at which the height of the ball is zero. Only a positive value of time makes sense, so only the zero t = 2 is meaningful.

• c., The ball is thrown from a height of 6 feet.

The equation that represents the distance, in kilometers, Seb travels (d) based on how many hours he bikes (t) at this rate is d = 20t

The given parameter is

constant rate of 20 kilometers per hour.

This means that

Rate = 20km per hour

When Seb bikes for t hours, the distance is

d = rate * t

This gives

d = 20t

Hence, the equation that represents the distance, in kilometers, Seb travels (d) based on how many hours he bikes (t) at this rate is d = 20t

This means that

t = 5

So, we have:

d = 20 * 5

The tangent line at that point is:

y = (-3/25)*x + 6/5

so m = -3/25, and b = 6/5

To find the slope at that point, we need to evaluate the derivative at that point.

y = 3/x

The derivative is:

y' = -3/x²

When x = 5, we have:

y' = -3/5² = -3/25

So that is the slope, m.

Now let's find the line.

The line must pass trhough the point (5, 3/5), then:

3/5 = (-3/25)*5 + b

3/5 = -3/5 + b

3/5 + 3/5 = b

Answer:

C. 11.60 ounces to 12.60 ounces

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.

Approximately 95% of the measures are within 2 standard deviations of the mean.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean 12.10, standard deviation 0.25.

In which range will the amount of water dispensed be found 95% of the time?

By the Empirical Rule, within 2 standard deviations of the mean. So

12.10 - 2*0.25 = 12.10 - 0.5 = 11.60

12.10 + 2*0.25 = 12.10 + 0.5 = 12.6

So the correct answer is given by option C.

Using statistics, the upper value and lower value of the range of outcomes associated with the middle 25% = (41, 53)

Understanding the data and focusing on various applications are the two main goals of statistics. The study of data gathering, analysis, and mathematical synthesis is known as statistics. As part of their state science studies, statisticians used to collect and evaluate data about a country's economy, population, and other aspects. Mathematical statistics is the application of mathematical ideas such as linear algebra, differential equations, mathematical analysis, and probability theories.

Given, the mean of the normal distribution = 47.

μ =47

The standard deviation is 6.

σ = 6

The formula for range = (μ-σ, μ+σ)

Putting the values of μ and σ,

Range= (47-6, 47+6)

Range= (41, 53)

Hence, the range of outcomes associated with the middle 25%'s upper and lower values are equal to (41, 53)

\(\frac{time}{distance}\) = \(\frac{time}{distance}\)

\(\frac{\frac{4}{5} }{\frac{3}{10} }\) = \(\frac{h}{1}\)cross multiply and solve for h

\(\frac{3}{10}\) h = \(\frac{4}{5}\)  Multiply both sides by \(\frac{10}{3}\)

\((\frac{10}{3})\)\(\frac{3}{10}\) h = \((\frac{10}{3})\)\(\frac{4}{5}\)  Multiply and then divide the top and bottom by 5

1.) The probability that the sample mean will be greater than 48 minutes is 0.9332.

2.) The probability of the sample mean being between 44 and 49 minutes is 0.6687.

3.) The z-score of 10 indicates that the sample mean of 65 minutes is 10 standard deviations above the population mean.

To solve this problem, we can use the Central Limit Theorem (CLT), which states that the distribution of sample means tends to be approximately normally distributed, regardless of the shape of the original population, when the sample size is large enough.

1.) Probability of sample mean > 48 minutes:

To calculate this probability, we need to standardize the sample mean using the formula: z = (x - μ) / (σ / √n), where x is the sample mean, μ is the population mean, σ is the population standard deviation, and n is the sample size.

In this case, the population mean (μ) is 45 minutes, the population standard deviation (σ) is 12 minutes, and the sample size (n) is 36. We want to find the probability of the sample mean being greater than 48 minutes.

Calculating the z-score:

z = (48 - 45) / (12 / √36) = 3 / 2 = 1.5

Using a standard normal distribution table or calculator, we find that the probability corresponding to a z-score of 1.5 is approximately 0.9332. Therefore, the probability that the sample mean will be greater than 48 minutes is approximately 0.9332.

2.) Probability of sample mean between 44 and 49 minutes:

To calculate this probability, we need to find the z-scores for both 44 and 49 minutes and then calculate the area between those z-scores.

Calculating the z-scores:

For 44 minutes:

z1 = (44 - 45) / (12 / √36) = -1 / 2 = -0.5

For 49 minutes:

z2 = (49 - 45) / (12 / √36) = 4 / 2 = 2

Using the standard normal distribution table or calculator, we find the probabilities corresponding to z1 and z2:

P(z < -0.5) ≈ 0.3085

P(z < 2) ≈ 0.9772

The probability of the sample mean being between 44 and 49 minutes is approximately P(-0.5 < z < 2) = P(z < 2) - P(z < -0.5) ≈ 0.9772 - 0.3085 = 0.6687.

3.)Conclusion from 100 samples with a mean of 65 minutes:

If 100 samples were collected, and the sample mean was 65 minutes, we would need to assess whether this value is significantly different from the population mean of 45 minutes.

To make this assessment, we can calculate the z-score for the sample mean of 65 minutes:

z = (65 - 45) / (12 / √36) = 20 / 2 = 10

The z-score of 10 indicates that the sample mean of 65 minutes is 10 standard deviations above the population mean. This is an extremely large deviation, suggesting that the sample mean of 65 minutes is highly unlikely to occur by chance.

Given this, we can conclude that the sample mean of 65 minutes is significantly different from the population mean. It may indicate that there is a systematic difference in the delivery times between the sample and the population, possibly due to factors such as increased demand, traffic, or other external variables
