The value of angle S is 53°

Exterior angle theorem states that the measure of an exterior angle of a triangle is equal to the sum of two remote interior angles.

With this theorem we can say that

7x+2 = 4x+13+19

collecting like terms

7x -4x = 13+19-2

3x = 30

divide both sides by 3

x = 30/3

x = 10

Since x = 10

angle S = 4x+13

angle S = 4(10) +13

= 40+13

= 53°

Therefore the measure of angle S is 53°

The relation S={(a,b)∈R×R:a²+b²=1} is not an equivalence relation on the set of real numbers R.

To show that S is not an equivalence relation, we need to demonstrate that it fails to satisfy one or more of the properties of an equivalence relation: reflexivity, symmetry, and transitivity.

Reflexivity: For a relation to be reflexive, every element of the set should be related to itself. However, in the case of S, there are no real numbers (a, b) that satisfy the equation a² + b² = 1 for both a and b being the same number. Therefore, S is not reflexive.

Symmetry: For a relation to be symmetric, if (a, b) is related to (c, d), then (c, d) must also be related to (a, b). However, in S, if (a, b) satisfies a² + b² = 1, it does not necessarily mean that (b, a) also satisfies the equation. Thus, S is not symmetric.

Transitivity: For a relation to be transitive, if (a, b) is related to (c, d), and (c, d) is related to (e, f), then (a, b) must also be related to (e, f). However, in S, it is not true that if (a, b) and (c, d) satisfy a² + b² = 1 and c² + d² = 1 respectively, then (a, b) and (e, f) satisfy a² + b² = 1. Hence, S is not transitive.

Since S fails to satisfy the properties of reflexivity, symmetry, and transitivity, it is not an equivalence relation on the set of real numbers R.

We square the residuals when using the least-squares line method to find the line of best fit because we believe that huge negative residuals (i.e., points well below the line) are just as harmful as large positive residuals (i.e., points that are high above the line).

We treat both positive and negative disparities equally by squaring the residual values.  We cannot discover a single straight line that concurrently minimizes all residuals. The average (squared) residual value is instead minimized.

We might also take the absolute values of the residuals rather than squaring them. Positive disparities are viewed as just as harmful as negative ones under both strategies.

a) Margine of error for the proportion of all U.S. adults who think things are on the wrong track for 95% confidence is 0.019.

b) Correct answer is B. One is 95% confident that the observed proportion of adults that responded "Wrong Track" is within ±0.019 of the population proportion.

a) To calculate the margin of error for the proportion of all U.S. adults who think things are on the wrong track for 95% confidence, we can use the following formula:

ME = z√((p(1-p))/n)

Where:

z = the z-score associated with the desired level of confidence (in this case, 1.96 for 95% confidence)

p = the proportion of adults in the sample who said things are on the wrong track

n = the sample size

Using the percentages provided in the question, we can calculate the sample proportion:

p = % of adults who said things are on the wrong track / 100

p = % / 100 = %

So, p =

We don't have the sample size, but we can assume it's large enough (at least 30) to use the normal distribution approximation. Therefore, we can use the percentages directly to calculate the margin of error:

ME = 1.96√((0.490.51)/n)

ME = 1.96√(0.2499/n)

ME = 1.96(0.499/n¹/²)

ME = 0.019

Hence the margine of error is 0.019.

b) The margin of error means that if we were to conduct the same survey many times and calculate a 95% confidence interval for the proportion of all U.S. adults who think things are on the wrong track using each sample, we would expect the true population proportion to be within ±0.019 of the sample proportion in 95% of the intervals.

Therefore, the correct answer is B. One is 95% confident that the observed proportion of adults that responded "Wrong Track" is within ±0.019 of the population proportion.

Step-by-step explanation:

First we should find out how much Ms. Maple would make in a week without overtime.

6.5 x 40 = 260

Now, let's figure out how much she makes per hour in overtime.

6.5 x 1.5 = 9.75

Now add up the hours of overtime.

9.75 x 3 = 29.25

Now we add the weekly wage to the overtime

260 + 29.25 = 289.25

For 40 hours of regular time at $6.50/hr and 3 hours of overtime at $9.75/hr, Ms. Maple will make $289.25 for the week.

Step-by-step explanation:

The number of small size and large size bowls of ice cream sold in the shop is 40 and 22 respectively.

let

Number of small bowl = x

Number of large bowl = y

x + y = 63

2.25x + 3y = 159

From (1)

x = 63 - y

Substitute into (2)

2.25x + 3y = 159

2.25(63 - y) + 3y = 159

141.75 - 2.25y + 3y = 159

- 2.25y + 3y = 159 - 141.75

0.75y = 17.25

divide both sides by 0.75

y = 17.25 / 0.75

y = 23

Substitute y = 23 into (1)

x + y = 63

x + 23 = 63

subtract 23 from both sides

x = 63 - 23

x = 40

In conclusion, The ice cream shop sold 40 small size bowls and 23 large size bowls

To determine if there has been a change in the distribution of motivations for using a credit card among college students, a survey of 425 students was conducted.

The alternate hypothesis states that the distribution of motivations differs from the old survey. The critical value and rejection region need to be determined to test this hypothesis.

To test if there has been a change in the distribution of motivations, the null hypothesis assumes that the distribution remains the same as in the old survey, while the alternate hypothesis suggests a difference. In this case, the alternate hypothesis is that the distribution of motivations differs from the old survey.

To determine the critical value and rejection region, the significance level (α) needs to be specified. In this case, α is given as -0.005. However, it seems there may be some confusion in the provided information, as a negative significance level is not possible. The significance level should typically be a positive value between 0 and 1.

Without a valid significance level, it is not possible to determine the critical value and rejection region for hypothesis testing. The critical value is typically obtained from a statistical table or calculated based on the significance level and the degrees of freedom.

Mrs. Byers will need 29 yards of red fabric for each of the 5 costumes she is making, based on the equation 690 + 5r = 834

Let's assume that each costume requires "r" yards of red fabric.

Since Mrs. Byers is making 5 costumes, the total amount of red fabric she will need is 5r

We know that the total amount of blue fabric used in all 5 costumes is 834 yards, and each costume requires 138 yards of blue fabric. Therefore, we can write

5 × 138 = 690

The total amount of fabric used in all 5 costumes is

690 + 5r

We also know that the total amount of fabric used in all 5 costumes is 834 yards. Therefore, we can write

690 + 5r = 834

This is the equation we can use to determine how much red fabric "r" is needed for each costume.

To solve for "r," we can start by subtracting 690 from both sides

5r = 834 - 690

5r = 144

Finally, we can divide both sides by 5 to isolate "r"

r = 28.8

r ≈ 29 yards

Step-by-step explanation:

maximum possible number = 25

On solving the linear equations y = -2x + 6 and y = 5x - 8, the value for x is x = 2 and the value of y is y = 2.

What is a linear equation?

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

The first linear equation is - y = -2x + 6

The second linear equation is - y = 5x - 8

Subtracting equation (1) from (2) -

y - y = 5x - 8 - (-2x + 6)

0 = 5x - 8 + 2x - 6

0 = 7x - 14

7x = 14

x = 14/7

x = 2

Substituting the value of y in equation (1) -

y = -2x + 6

y = -2(2) + 6

y = -4 + 6

y = 2

The subtraction and substitution method is chosen to solve the system of linear equations. The linear equations are first made equal in order to find the desired variable. Then subtraction is done to find the value of one variable. Next, the found value is substituted into the equation to find the unknown variable. This method is easy to understand and gives accurate value.

Therefore, the value of x and y is 2 and 2 respectively.
