Assuming the coordinates of point A are (3, 5): we would have the following results.

1. To reflect over the x-axis: the x-coordinate remains the same and the y-coordinate changes sign. So point B will have the same x-coordinate as point A (3), but the y-coordinate will be -5. Therefore, the coordinates of point B are (3, -5).

2. To reflect over the y-axis: the y-coordinate remains the same and the x-coordinate changes sign. So point C will have the same y-coordinate as point A (5), but the x-coordinate will be -3. Therefore, the coordinates of point C are (-3, 5).

3. To translate: add the given values to the x and y coordinates. So point D will have an x-coordinate of 3 + 3 = 6, and a y-coordinate of 5 + 4 = 9. Therefore, the coordinates of point D are (6, 9).

4. To rotate 180 degrees clockwise: flip the signs of both the x and y coordinates and then swap them. So point E will have an x-coordinate of -5 and a y-coordinate of -3. Therefore, the coordinates of point E are (-5, -3).

Plotting these points on a graph,

The length 53.1°, 90°, and 39.9°,vertical length: 3/5 ,length of vertical: 4/5 1 hypotenuse.

Angle is a geometric concept that describes the relative difference between two straight lines or planes that meet at a common point. It is measured in degrees, radians or grads, and is often represented by the symbol θ. An angle can be acute, right, obtuse, straight, reflex, or full. Angles can be used to measure the size of a triangle, to calculate the area of a figure, and to determine the position of a point in a coordinate system.

We possess that

Angle = 53.1°

Vertical length = 3/5 (this is the adjacent cathetus)

Vertical length equals 4/5 (this is the opposite cathetus)

We can use it to check this.

tg(angle) = adjacent/opposite:

tg(53.1) = 1.33

and

(4/5)/(3/5) = 4/3 = 1.33

This makes sense, then.

Using the relationship, we can now identify the hypotenuse:

Sin(angle) = the antipode or hypotenuse

sin(53.1) = (4/5)/H

H = (4/5)/sin(53.1) = 1

Hence, there is always a 90° angle in a triangle or rectangle.

We may get the final angle using the fact that the sum of a triangle rectangle's three interior angles is always 180 degrees.

A + 53.1° + 90° = 180°

A = 90° - 53.1° = 36.9°

To complete her journey Ann needs to run for (120/3) = 40 minutes in order to travel at an average speed of 5 km/h.

We can start by using the formula:

average speed = total distance ÷ total time

Let's first calculate the total distance Ann covers:

distance walked = speed x time = 4 km/h x (8 km / 4 km/h) = 8 km

distance run = speed x time

Let's call the time Ann runs for "t". Then:

distance run = 8 km/h x (t/60) h = (8t/60) km

Total distance = distance walked + distance run = 8 km + (8t/60) km = (480 + 8t) / 60 km

Now, let's find the total time:

total time = time walked + time run

time walked = distance ÷ speed = 8 km ÷ 4 km/h = 2 h

time run = t/60 h

total time = 2 h + t/60 h = (120 + t)/60 h

Now we can substitute the values we have found into the formula for average speed:

5 km/h = [(480 + 8t)/60 km] ÷ [(120 + t)/60 h]

Simplifying the right-hand side, we get:

5 km/h = (480 + 8t) / (120 + t)

Multiplying both sides by (120 + t), we get:

600 + 5t = 480 + 8t

Subtracting 480 and 5t from both sides, we get:

120 = 3t

Therefore, Ann has to run for (120/3) = 40 minutes to have an average speed of 5 km/h over her complete journey.

The sum of the arithmetic series of 28 + 28.4 ...+ 42 is 1260.

An arithmetic series is a sequence of numbers in which each term is obtained by adding a constant difference, called the common difference, to the preceding term.

To resolve this issue, we can utilise the following formula for the sum of an arithmetic series:

S = (n/2) * (a₁ + aₙ)

When n is the number of terms, a1 is the first term, and an is the nth term, S is the series total.

To find the number of terms, we need to figure out the pattern of the series. The common difference (d) is expressed as follows:

d = 28.4 - 28 = 0.4

To get from 28 to 42, we need to add (42 - 28)/0.4 = 35 terms.

So the number of terms is:

n = 35 + 1 = 36

The first term is a₁ = 28, and the last term is aₙ = 42.

Now we can plug these values into the formula:

S = (n/2) * (a₁ + aₙ)

= (36/2) * (28 + 42)

= 18 * 70

= 1260

Therefore, the sum of the arithmetic series is 1260.

y = 1/3x - 5

Step-by-step explanation:

The equation is y = mx + b

m = the slope

b = y-intercept

m = 1/3

Y-intercept is located at (0, -5)

So, the equation of the line is y = 1/3x - 5

An equation in slope-intercept form of the line that passes through (-3, 2) and (-2, - 5) is: C. y = -7x - 19.

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation:

y - y₁ = m(x - x₁)

Where:

First of all, we would determine the slope of this line;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (-5 - 2)/(-2 + 3)

Slope (m) = -7/1

Slope (m) = -7

At data point (-3, 2), a linear equation in slope-intercept form for this line can be calculated as follows:

y - y₁ = m(x - x₁)

y - 2 = -7(x + 3)

y = -7x - 21 + 2

First, we can calculate the discount from the sale. The sweater costs $65.99, and with a 40% discount, the price is reduced by:

$65.99 x 0.40 = $26.40

So the sale price of the sweater is:

$65.99 - $26.40 = $39.59

Next, we can apply Carson's $10 coupon to the sale price:

$39.59 - $10 = $29.59

Therefore, Carson pays $29.59 for the sweater after the discounts.

To calculate the total discount that Carson receives, we can first find the amount of the 40% discount on the sweater, which is:

40% of $65.99 = 0.4 x $65.99 = $26.40

Then, we can add the additional $10 coupon discount to get the total discount:

$26.40 + $10 = $36.40

Therefore, the total discount that Carson receives on the sweater is $36.40.

To find the final price that Carson pays after the discounts, we can subtract the total discount from the original price:

$65.99 - $36.40 = $29.59

Therefore, Carson pays $29.59 for the sweater after the discounts.

The probability that a randomly selected part is not defective is 47/50.

Probability is a way of calculating how likely something is to happen. It is difficult to provide a complete prediction for many events. Using it, we can only forecast the probability, or likelihood, of an event occurring. The probability might be between 0 and 1, where 0 denotes an impossibility and 1 denotes a certainty.

Here Total number of parts machine makes = 50

Number of parts defective out of 50 = 3

Then number of parts not defective out of 50 = 50-3 = 47.

Now using probability formula:

Probability = No of favorable item/ Total no of item

Now probability that a randomly selected part is not defective is,

= 47/50.

d. The value of test statistic is 3.15 and p value is 0.05.

e. The mean diameter of bearings from machine 2 is greater than that of machine 1 at a 5% level of significance.

To begin the hypothesis test, the manager needs to state the null and alternative hypotheses. The null hypothesis (H0) is the statement of "no difference" between the mean diameters of bearings from the two machines. The alternative hypothesis (Ha) is the statement that the mean diameter of bearings from machine 2 is greater than that of machine 1.

In symbols,

H0: μ1 = μ2 (where μ1 is the mean diameter of machine 1 and μ2 is the mean diameter of machine 2) and

Ha: μ2 > μ1.

Before conducting the hypothesis test, we need to check some assumptions.

The next step is to calculate the test statistic and p-value. We use a t-test to compare the means of two independent samples. The test statistic is calculated as:

t = (x₁ - x₂) / [s_p x √(2/n)]

where x₁ and x₂ are the sample means, s_p is the pooled standard deviation, and n is the sample size.

Plugging in the numbers, we get:

t = (3.355 - 3.302) / [0.050 x √(2/50)] = 3.15

Using a t-distribution table with 98 degrees of freedom (n₁ + n₂-2), we find that the p-value associated with a t-value of 3.15 is less than 0.01.

Finally, we need to state our conclusion based on the p-value. Since the p-value is less than our significance level of 0.05, we reject the null hypothesis.

The percentage of data between 13.8 and 30.2 in a normally distributed data set with a mean of 22 and a standard deviation of 4.1 is approximately 94.19%.

To solve this problem, we can first standardize the values of interest using the standard normal distribution formula, z = (x - μ) / σ, where x is the value of interest, μ is the mean, and σ is the standard deviation.

For the lower value of 13.8, we have z = (13.8 - 22) / 4.1 = -1.95. For the upper value of 30.2, we have z = (30.2 - 22) / 4.1 = 2.05.

Next, we can use a calculator to find the area between these two z-scores. Alternatively, we can use the complement rule to find the area to the left of -1.95 and the area to the right of 2.05, and subtract their sum from 1.

Using a calculator, we find that the area between -1.95 and 2.05 is approximately 0.9419 or 94.19%. Therefore, approximately 94.19% of the data falls between 13.8 and 30.2 in this normally distributed data set.
