The answer choice that is the best measure of center for the data, and what is its value is D. The median is the best measure of center, and it equals 8.

A measure of center gives an idea of the central tendency of the data.

The median is a better choice here because it is not affected by extreme values, unlike the mean.

From the dots plotted on the line graph, it is evident that there are more data points around 8 than any other value. Hence, the median of the data would be closest to 8.

To add or subtract fractions they must have a common denominator

  you can multiply them together to find A common denominator

   2 x 9 = 18

so now yo have to convert the fractions to 18ths

1/2 * 9/9    ( this is just multiplying by '1') = 9/18

5/9 * 2/2 = 10 / 18    

now 1/2 - 5/9  then equals  9/18 - 10/18 = (9-10)/18 = - 1/18

Step-by-step explanation:

The velocity of the particle at a given value of θ can be found by taking the derivative of the position vector with respect to time:

v(θ) = dr/dt = dr/dθ * dθ/dt = dr/dθ * ω

where ω is the angular velocity and dr/dθ is the derivative of the position vector with respect to θ.

The position vector r = a * e^(b * θ) * i + a * b * e^(b * θ) * j

Taking the derivative with respect to θ:

dr/dθ = a * b * e^(b * θ) * i + a * b^2 * e^(b * θ) * j

So the velocity of the particle is given by:

v(θ) = a * b * e^(b * θ) * ω * i + a * b^2 * e^(b * θ) * ω * j

Answer:

Step-by-step explanation:

v(θ) = a * b * e^(b * θ) * ω * i + a * b^2 * e^(b * θ) * ω * jj

The value of x is 7.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

∠TUV = 9x + 1

∠TUW = 7x - 9

∠WUV = 5x - 11

Now,

∠TUV = ∠TUW + ∠WUV

Substituting the values.

9x + 1 = 7x - 9 + 5x - 11

Adding like terms.

9x + 1 = 12x - 20

1 + 20 = 12x - 9x

21 = 3x

Dividing 3 on both sides.

x = 21/3

x = 7

Thus,

x is 7.

The distance across the lake is approximately 62.5 meters, rounded to the nearest hundredth of a meter.

To find the distance across the lake (BC), we can use the following formula based on triangle similarity:

BC/AD = DB/DE

Where BC is the distance across the lake, AD is the known direct measurement made by Dominic, DB is the known measurement from point B to the landmark, and DE is the known measurement from point D to the landmark.

Let's assume that AD = 100 meters, DB = 50 meters, and DE = 80 meters. Then we can calculate BC as follows:

BC = (BC/AD) * AD = (DB/DE) * AD

BC = (50/80) * 100

BC = 62.5 meters

So, the distance across the lake is approximately 62.5 meters, rounded to the nearest hundredth of a meter.

The possible values are -

(a²,b²) = p

(a²,b) = p if p|-r and (a²,b) = p² if p|r

(a²,b³) = p² if p|-r and (a²,b³) = p³ if p|r

What is gcd?

The greatest common factor (GCF) that divides two or more numbers is known as the greatest common divisor (GCD). The highest common factor is another name for it (HCF).

Since (a, b) = p it can be written a = pr and b = ps where r and s are integers such that (r, s) = 1.

Then a² = p²r².

Then by Theorem 1.7, (a²,b) = (p²r²,ps) = p(pr²,s).

By Theorem 1.8, (r²,s) = 1 .

Thus, there are two cases to consider: if p|s then, (a²,b) = p², and if p|-s then (pr²,s) = 1 (Again by Theorem 1.8)  so that (a²,b) = p in that case.

Thus, there are two cases for (a²,b): namely p or p².

The same analysis shows that (a³,b) must be either p, p² or p³ depending on the power of p that divides b.

Analyze (a²,b³) as follows.

Using the notation already introduced, and

Theorem 1.7, it is obtained that (a²,b³) = (p²r²,p³s³) = p²(r²,ps³).

Since, (r, s) = 1, Theorem 1.8 shows that (r²,s³) = 1.

Therefore, there are two possibilities for (a²,b³) -

(a²,b³) = p² if p|-r and (a²,b³) = p³ if p|r.

The measure of angle Y, according to the stated statement, is 55 degrees.

An adverb used to describe something which goes together with something else and improves or completes it is complimentary (as in complementary colors)

The total of two complimentary angles is 90 degrees. As a result, we have:

m∠S + m∠Y = 90

Substituting the given equation m∠S = 5(m∠Y) − 240°, we get:

5(m∠Y) − 240° + m∠Y = 90

By merging like variables in the equation, we can reduce it to:

6(m∠Y) - 240° = 90

Adding 240 to both sides, we get:

6(m∠Y) = 330

Dividing both sides by 6, we get:

m∠Y = 55

Therefore, the measure of angle Y is 55 degrees.

The percent markup for the cost of shirt = 50%

Let us assume that the cost of each shirt be x dollars

A department store buys 300 shirts at a cost of $1,800.

Using unitary method the price of each shirt would be,

x = 1800/300

x = 6 dollars

A department store sells 300 shirts for $9 each.

So, Selling price of one shirt = $9

Price markup = Selling price - Cost price

                      = $9 - $6

                      = $3

The percent markup would be,

p = (Price markup / cost price) × 100

p = (3/6) × 100

p = 50%

Total number of paintbrushes

= 53 ÷ 25%

= 53 ÷ 0.25

= 212

Answer:

If 53 paintbrushes represent 25% of the total number of paintbrushes Daniel has, we can use the following formula to find the total:

total number of paintbrushes = (number of paintbrushes / percentage) x 100

Plugging in the values we know, we get:

total number of paintbrushes = (53 / 25) x 100

Simplifying, we get:

total number of paintbrushes = 212

Therefore, Daniel has a total of 212 paintbrushes in all.

Step-by-step explanation:

a. The equation of the line that describes the relationship between distance and time for Car X can be found by using the slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept.

To find the slope (m), we can use the formula: m = (change in y) / (change in x) = (distance traveled) / (time elapsed) = 174 miles / 3 hours = 58 miles per hour.

Since the car starts at time x = 0 and has traveled 174 miles at time x = 3, the y-intercept (b) can be found by setting x = 0 and solving for y: y = 58x + b, and y = 174 when x = 3, so b = 174 - 58(3) = -160.

Putting it all together, we get the equation: y = 58x - 160.

b. The graph that represents the relationship between distance and time for Car X is a line that passes through the point (0, -160) and has a slope of 58. This line represents the linear relationship between the distance traveled and the time elapsed for Car X.

The y-intercept of -160 represents the distance traveled when time is equal to 0. The slope of 58 represents the rate of change of the distance traveled with respect to time. This means that for every hour that passes, Car X travels 58 miles.

According to the mathematical calculations made, the results are as follows: the length of DF is 3.87 cm, the length of XF is 4.89 cm. The point 2cm from E is 5cm from X and the angle of D is 60°.

In this problem, we have to apply the Pythagorean theorem to find the lenght of DF line.

a² + b² = c²

7² + b² = 8²

49 + b² = 64

b² = 15

b = 3.87

In this problem, we have to apply the Pythagorean theorem to find the lenght of XF line.

a² + b² = c²

3² + 3.87² = c²

9 + 14.97 = c²

23.97 = c²

4.89 = c

According to the information of the graph we can conclude that the point 2cm from E is on the line EX, and it is located 2cm from E and 5cm from X.

We know that F has a angle less than D so we can infer that F has an angle of 30° and D has an angle of 60° which we can check with a compass.
