Answer:

38*

Step-by-step explanation:

verticle angles are always going to be equivilent so the opposite of x is 38 so x also =38

The measure of angle x from the intersecting lines is x = 28°

Two straight lines that intersect at the same location are said to be intersecting lines. The junction point is the place where two intersecting lines meet. Four angles are created when two lines cross. The four angles added together always equal 360 degrees.

Perpendicular lines are two straight lines that intersect and form right angles. When two perpendicular lines intersect, they form four right angles.

When lines intersect, two angle relationships are formed:

Opposite angles are congruent

Adjacent angles are supplementary

Given data ,

Let the lines represented by the figure be intersecting lines

And , the missing angle from the first straight line be y

where y = 180° - ( 38° + 90° )

On simplifying , we get

y = 52°

Now , the measure of x is given by

90° + y + x + 10 = 180° ( angles on a straight line )

On simplifying , we get

90 + 52 + 10 + x = 180

Subtracting 152 on both sides , we get

x = 28°

Hence , the measure of angle is x = 28°

Therefore, Laura will earn $495 if she works 50 hours this week, taking into account the time-and-a-half overtime pay for any hours worked beyond 40.

To calculate Laura's earnings for the week, we need to consider her regular pay rate and the overtime pay for any hours worked beyond 40.

Laura earns $9 per hour, so her regular pay rate is $9.

Let's calculate her earnings for the week:

Regular hours worked: 40 hours

Overtime hours worked: 50 hours - 40 hours = 10 hours

Regular pay for 40 hours = 40 hours * $9/hour = $360

Overtime pay for 10 hours = 10 hours * ($9/hour * 1.5) = $135

Total earnings for the week = Regular pay + Overtime pay = $360 + $135 = $495

Applying the Inscribed Angle Theorem, the measure of arc IJ is calculated as: 50°

The Inscribed Angle Theorem, also known as the Central Angle Theorem, states that an angle inscribed in a circle is half the measure of the central angle that intercepts the same arc, as well as half of the measure of the intercepted arc.

Since HK is a diameter, then arc HIK = 180°

Arc IH = 2(38) = 76° [Inscribed Angle Theorem]

Arc JK = 2(27) = 54° [Inscribed Angle Theorem]

Measure of arc IJ = 180 - 76 - 54 = 50°

The mean, median, and sample variance of the given dataset are:Mean = 23.17Median = 21Sample variance = 173.5592

(a) Mean The mean (or average) of a dataset is calculated by summing up all the values and dividing by the total number of values.

The formula for calculating the mean is: `mean = (sum of values) / (total number of values)`For the given dataset, we have:20, 50, 22, 14, 23, 10

Sum of values = 20 + 50 + 22 + 14 + 23 + 10 = 139

Total number of values = 6Therefore, the mean is given by: `mean = 139 / 6 = 23.17`Answer: 23.17 (rounded to two decimal places)

(b) Median To find the median, we need to arrange the dataset in increasing order:10, 14, 20, 22, 23, 50The median is the middle value of the dataset. If there are an odd number of values, the median is the middle value. If there are an even number of values, the median is the average of the two middle values. Here, we have 6 values, so the median is the average of the two middle values: `median = (20 + 22) / 2 = 21` Answer: 21(e)

Sample variance s²The sample variance is calculated by finding the mean of the squared differences between each value and the mean of the dataset.

The formula for calculating the sample variance is: `s² = ∑(x - mean)² / (n - 1)`where `∑` means "sum of", `x` is each individual value in the dataset, `mean` is the mean of the dataset, and `n` is the total number of values.For the given dataset, we have already calculated the mean to be 23.17.

Now, we need to calculate the squared differences between each value and the mean:

20 - 23.17 = -3.1722 - 23.17

= -1.170 - 23.17

= -13 - 23.17

= -9.1723 - 23.17

= -0.1710 - 23.17

= -13.17

The sum of the squared differences is given by:

∑(x - mean)² = (-3.17)² + (-1.17)² + (-13.17)² + (-9.17)² + (-0.17)² + (-13.17)²

= 867.7959

Therefore, the sample variance is given by: `s² = 867.7959 / (6 - 1) = 173.5592`Answer: 173.5592 (rounded to four decimal places)

The mean, median, and sample variance of the given dataset are:Mean = 23.17Median = 21Sample variance = 173.5592

Answer:

54 inches

Step-by-step explanation:

First, let's convert the measurements into a common measurement.

Since inch is the smallest measurement here, let's use that.

Ella's pet snake is 42 inches long.

Roya's pet snake is 8 feet long. There are 12 inches in one foot. Therefore, 8 feet would mean 12 times 8 or 96 inches.

Therefore, Roya's snake is 96 inches long.

To find out how many inches longer is Roya's snake, subtract:

96 - 42 = 54.

Therefore, Roya's snake is 54 inches longer than Ella's.

Answer:

x = 20

4x = 80°

5x = 100°

Step-by-step explanation:

The given angles are supplementary so their sum is 180°

4x + 5x = 180

9x = 180 divide both sides by 9

x = 20

The value of the angle marked 4x = 4 × 20 = 80°

The value of the angle marked 5x = 5 × 20 = 100°

Answer:

80°, 100°

Step-by-step explanation:

The 2 angles are same- side interior angles and are supplementary, thus

4x + 5x = 180

9x = 180 ( divide both sides by 9 )

x = 20

Thus

4x = 4 × 20 = 80°

5x = 5 × 20 = 100°

The dimensions of the rectangular room are 6 meters by 4.3 meters.

Let's assume the width of the room is x meters. According to the given information, the length of the room is 1.4 times the width, which can be expressed as 1.4x meters.

The perimeter of a rectangle is calculated by adding the lengths of all its sides. In this case, the perimeter is given as 26 meters. We can set up the equation 2x + 2(1.4x) = 26 to represent the sum of the lengths of all four sides.

Simplifying the equation, we have 2x + 2.8x = 26, which combines to 4.8x = 26. Dividing both sides of the equation by 4.8 gives x ≈ 5.42.

Therefore, the width of the room is approximately 5.42 meters, and the length is 1.4 times that value, approximately 7.58 meters.

In conclusion, the dimensions of the rectangular room are approximately 6 meters by 4.3 meters.

Answer:

6 because 4.5 divided by 0.75 equals 6.

Step-by-step explanation:

Let's try to understand how we can solve this equation

Given equation,4f+2=6f-12

Now we will take the terms on one side and constants on the other.

=> 2+12=6f-4f

=> 14=2f

=>7=f

So, the value of f would be 7. Remember that while bringing value to another side, the sign of that value changes. If it is a positive sign then it is going to be transformed into a negative one and vice versa.

Answer:

a) Point (42, 30,000)

b) The salaries are directly proportional to the age of a surgeon to a large extent

c) By performing regression analysis

Step-by-step explanation:

a) From the given information;

Given that Igor is an experienced surgeon that just completed his medical training, Igor has;

1) Years of experience

2) Redid his medical training to obtain the same qualification with more time spent

3) Able to work only with his newly acquired re-qualification

Therefore, Igor will receive wages similar to other recently trained surgeons that have similar years of experience post Igor's re-qualification

The point that most likely will represent Igor's data will have his years of experience and wage commensurate with his UK based post qualification experience, which is the point (42, 30,000)

b) Because from the graph apart from the two points, (that of Igor and (34, 44,000)), the salaries of the other points vary proportionately with the age of the Surgeon

c) By carrying out a regression analysis as follows;

A = 50, 55,000

B = 42, 46,000

C = 38, 42,000

D = 34, 44,000

E = 42, 30,000

Answer:

f(g(2)) = 2

Step-by-step explanation:

g(2)

g is the inverse function of x, which means that \(g(2)\) is the value of x for which \(f(x) = 2\), which is \(x = -3\), and thus, \(g(2) = -3\)

f(g(2))

\(g(2) = -3\)

Thus

\(f(g(2)) = f(-3)\)

Looking at the table, when \(x = -3, f(x) = 2\)

Thus: \(f(g(2)) = 2\)

Answer:

any luck bro with this question

Step-by-step explanation:

Question 3: True

Question 4: False

Question 5: True

If the derivative of a function, f'(x), is positive for values of x less than c and negative for values of x greater than c, then it indicates a change in the slope of the function. This change from positive slope to negative slope suggests that the function has a maximum value at x = c.

This is because the function is increasing before x = c and decreasing after x = c, indicating a peak or maximum at x = c.

Question 3: If f'(c) < 0 then f(x) is decreasing and the graph of f(x) is concave down when x = c.

True

When the derivative of a function, f'(x), is negative at a point c, it indicates that the function is decreasing at that point. Additionally, if the second derivative, f''(x), exists and is negative at x = c, it implies that the graph of f(x) is concave down at that point.

Question 4: A local extreme point of a polynomial function f(x) can only occur when f'(x) = 0.

False

A local extreme point of a polynomial function can occur when f'(x) = 0, but it is not the only condition. A local extreme point can also occur when f'(x) does not exist (such as at a sharp corner or cusp) or when f'(x) is undefined. Therefore, f'(x) being equal to zero is not the sole requirement for a local extreme point to exist.

Question 5: If f'(x) > 0 when x < c and f'(x) < 0 when x > c, then f(x) has a maximum value when x = c.

True

If the derivative of a function, f'(x), is positive for values of x less than c and negative for values of x greater than c, then it indicates a change in the slope of the function. This change from positive slope to negative slope suggests that the function has a maximum value at x = c. This is because the function is increasing before x = c and decreasing after x = c, indicating a peak or maximum at x = c.
