Step-by-step explanation:

According to the ratio:

Josh has 9 sweets less than John.

Use the difference to find the value of x:

John has:

Step 1: Use the slope formula y₂ - y₁/x₂ - x₁ to find the slope.

\(\frac{0 - (-4)}{-3 - 3}\\ \\\frac{4}{-6} = -\frac{2}{3}\)

Step 2: Plug the slope we found and one point into the slope-intercept formula, y = mx + b.

\(y = mx + b\\\\0 = -\frac{2}{3}(6) + b\\\\0 = -4 + b\\\\4 = b\)

Step 3: Put it all together.

\(y = -\frac{2}{3}x + 4\)

The inequality that can be used to find w, the number of weeks it can take for the shelter to meet its goal, is: w ≥ 10

To find the inequality that can be used to determine the number of weeks it can take for the animal shelter to meet its fundraising goal, we need to consider the total expenses and donations.

Let's break down the expenses and donations:

Expenses:

Annual rental = $2,500

Weekly expenses = $450

Donations:

One-time donation = $125

Pledged donations per week = $680

Let w represent the number of weeks it takes for the shelter to meet its goal.

Total expenses for w weeks = Annual rental + Weekly expenses * w

Total expenses = $2,500 + $450w

Total donations for w weeks = One-time donation + Pledged donations per week * w

Total donations = $125 + $680w

To meet the goal, the total donations must be greater than or equal to the total expenses. Therefore, the inequality is:

Total donations ≥ Total expenses

$125 + $680w ≥ $2,500 + $450w

Simplifying the inequality, we have:

$230w ≥ $2,375

Dividing both sides of the inequality by 230, we get:

w ≥ $2,375 / $230

Rounding the result to the nearest whole number, we have:

w ≥ 10

Therefore, the inequality that can be used to find w, the number of weeks it can take for the shelter to meet its goal, is:

w ≥ 10

The equation of the circle is:  x² + y² = 123

The distance  through the center of the circle is called the diameter. The distance from the center of the circle to any point on the border is called the radius. The radius is half  the diameter; 2r = d 2 r = d.

A straight line connecting two points of a circle is a chord.  The equation of a circle with center (0,0) and radius r is given by:

x² + y² = r²

To find the value of R, we can use the fact that the point (5.7√2) is on the circumference of the circle. Substituting x=5 and y=7√2 in the circular equation, we get:

5² + (7√2)² = r²

Simplifying this equation, we get:

25 + 98 = r²

123 = r²

Taking the square root of both sides gives us:

r = √123

So the equation of the circle is:

Answer:

  B.  False

Step-by-step explanation:

You want to know if it is true that when each of seven persons in a group shakes hands with each of the other six persons, a total of forty-two handshakes occurs.

The count of 42 handshakes includes every one of 7 shaking hands with each of the remaining 6, without regard to whether they met before.

The count will include A shaking hands with B, and B shaking hands with A. That handshake will be counted twice, so the number 42 overstates the actual number of handshakes by a factor of 2.

It is false that there will be 42 handshakes. (There will be only 21.)

Answer:

m∠WZX = 41°

Step-by-step explanation:

diagonals bisect angles and opposite angles are congruent

therefore, ∠WXY ≅ ∠WZY

∠WZY must equal [360 - 2(68)] ÷ 2 which equals 112°

If ∠WXZ = 71° then so does ∠XZY

Which means that ∠WZX must equal 112-71 which is 41°

===================================================

Explanation:

Refer to the diagram below. I've marked up the figure with various angles to point out the angles we'll be working with.

To make things a bit simpler in terms of notation, and to match up colors with variable letters, I'm going to use the following

Notice how the two red angles I've marked up are alternate interior angles. This works because WX is parallel to ZY. Also notice that the red and blue angles combine to form the angle WZY, which is adjacent to angle XYZ in green.

For any parallelogram, the adjacent angles always add to 180.

(angle WZY) + (angle XYZ) = 180

(blueAngle+redAngle) + (greenAngle) = 180

(B+R) + (G) = 180

(B+71) + (68) = 180

B+139 = 180

B = 180-139

B = 41

The blue angle is 41 degrees, which means angle WZX is 41 degrees

The confidence level of the study with 72 scores and a standard deviation of 2.9 is approximately 97.5%. This means that we can be 97.5% confident that the findings of the study accurately represent the larger population.

The confidence level of a study refers to the level of certainty or reliability that can be placed on the results obtained from the study. It is often expressed as a percentage and indicates the likelihood that the findings of the study are representative of the larger population.

To calculate the confidence level, we need to know the sample size, the standard deviation, and the desired level of confidence. In this case, the sample size is 72 and the standard deviation is 2.9. The level of confidence is typically expressed as a percentage and is denoted by the Greek letter alpha (α). Common levels of confidence include 90%, 95%, and 99%.

To calculate the confidence level, we use the following formula:

Confidence Level = 1 - (α/2)

Where α/2 is the significance level, which is equal to (1 - Confidence Level)/2. Let's assume a desired confidence level of 95%. Using the formula, we can calculate the significance level as follows:

Significance Level =

(1 - 0.95)/2

= 0.025

To find the confidence level, we need to look up the critical value associated with the significance level in the standard normal distribution table (also known as the z-table). For a two-tailed test, the critical value is the positive z-value that corresponds to the significance level.

Looking up the z-value associated with a significance level of 0.025 in the z-table, we find a value of approximately 1.96. Now, we can calculate the confidence level:

Confidence Level =

1 - (0.025) =

0.975

To express the confidence level as a percentage, we multiply by 100:

Confidence Level =

0.975 * 100 =

97.5%

Therefore, the confidence level of the study with 72 scores and a standard deviation of 2.9 is approximately 97.5%. This means that we can be 97.5% confident that the findings of the study accurately represent the larger population.

Step-by-step explanation:

We can say that approximately 95% of the total snowfall per year in Laytonville falls between 71 inches (99 - 2*14) and 127 inches (99 + 2*14).

According to the empirical rule, for a normal distribution, approximately 68% of the data falls within 1 standard deviation of the mean, 95% falls within 2 standard deviations, and 99.7% falls within 3 standard deviations.

Using this rule, we can calculate that the upper limit of 1 standard deviation above the mean is:

99 + 14 = 113 inches

And the upper limit of 2 standard deviations above the mean is:

99 + (2*14) = 127 inches



To answer the specific question, the probability that in a randomly selected year, the snowfall was less than 127 inches is approximately 95%. This can be interpreted as saying that in 95 out of 100 years, the total snowfall in Laytonville is less than 127 inches. As a percentage, this is rounded to 95.00%.

It is important to consider the limitations of case studies when interpreting the results.

The limitation of case studies is that it can be difficult to generalize from one person to the larger population. Case studies are a type of research method that is used to get a detailed understanding of an individual, group, or event. They are typically used when the researcher wants to answer questions about the ‘how’ and ‘why’ of phenomena, which cannot be answered using other methods such as surveys or experiments.

While case studies can be useful in providing an in-depth analysis of an individual or group, they have certain limitations that need to be taken into consideration. One of the primary limitations of case studies is that it is difficult to generalize from one person to the larger population.

This is because case studies are typically conducted on a single individual or a small group of individuals, which makes it difficult to make inferences about larger populations. This means that the findings of a case study cannot be applied to a broader population without further research.

We can use the concept of System of Equations to solve this question. The answer for part A is 0 and even for part B is 0.

A two-variable linear equation is one with the formula ax + by + c = 0, where a, b, c R, a, and b 0. By comparing the coefficients of the variables in the equations, we may determine how many solutions there are to a system of linear equations. Take into account the pair of linear equations involving x and y.

a1x + b1y + c1 = 0

a2x + b2y + c2 = 0

Here, the real numbers a2, b2, and c2 are all present.

Keep in mind that a12 + b12 0 and a22 + b22 0

1. There will be a singular solution if (a1/a2) (b1/b2).

2. There will be an endless number of solutions if (a1/a2) = (b1/b2) = (c1/c2).

3. There won't be a solution if (a1/a2) = (b1/b2) ≠(c1/c2).

Part A:

       4x+6y=24

       2x+3y=8 are the given solutions are they are in the form of linear equations.

a1/a2 =2 b1/b2=2 and c1/c2=3

So according to the condition 3 , there will no solution if both the lines are parallel and a1/a2 =b1/b2 ≠c1/c2.

∴ So No.of solutions are Zero.

Part B:

   In the updated system,

             12x+18y=72

              2x+3y=8

a1/a2 =6 b1/b2 =6 and c1/c2=9.

So according to the condition 3 , there will no solution if both the lines are parallel and a1/a2 =b1/b2 ≠c1/c2.

So they have same no.of solutions as the original system.

We can use the concept of System of Equations to solve this question. The answer for part A is 0 and even for part B is 0.
