What are the medians for the height and weight distribution, respectively?

The 8% of us states have names that start with the letter w the answer is 8%.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

The complete question is:

Of the 50 us states 4 have names that start with the letter w what percentage of us states have names that start with the letter w.

The percentage of the US states that have names that start with the letter W can be calculated:

Percentage = (No of US states starting with W/Total no of US states)×100

Percentage = (4/50)×100

Percentage = 8%

Thus, the 8% of us states have names that start with the letter w the answer is 8%.

Answer:

  1/4

Step-by-step explanation:

The inverse function tells you the input value that corresponds to the given output value of the function.

You want f^-1(3), which is the value of x such that f(x) = 3.

  f(x) = 3 = 4x +2

  1 = 4x . . . . . . subtract 2

  1/4 = x . . . . . divide by 4

The inverse function of 3 is 1/4:

Answer:

Step-by-step explanation:

To find the total perimeter of the parallelogram we must add 200+200+150+150

This equals 700. Then, since squares have side lengths that are all equal, we have to divide by 4.

700 / 4 = 175

So, the length of a side of a square having this perimeter would be 175mm

Answer:

Step-by-step explanation:

Total number of candies =60

Number of Green candies, n(G)=36

Number of candies with caramel, n(C)=45

Since the events are independent, the probability of selecting two candies where the first is green and the second has caramel is given by:

P(GC)=P(G) X P(C)

\begin{gathered}=\dfrac{n(G)}{n(S)} X \dfrac{n(C)}{n(S)} \\=\dfrac{36}{60} X \dfrac{45}{60}\\ =\dfrac{9}{20}\end{gathered}=n(S)n(G)Xn(S)n(C)=6036X6045=209

The probability in its lowest form is 9/20.

Length of AB = 18. 92

Length of AC = 26. 15

Length of BC = 32. 552

Using the Pythagorean theorem, we have that

Expand the bracket

[tex]400x^2- 4 = 144x^2 + 400 + 625x^2[/tex]

Collect like terms

[tex]400x^2 - 144x^2 - 625x^2 = 400 + 4[/tex]

[tex]-369x^2 = 404[/tex]

Make x^2 subject

[tex]x^2 = \frac{404}{369}[/tex]

[tex]x = \sqrt{1.0948}[/tex]

[tex]x = 1. 046[/tex]

Thus,

Length of AB = 20x -2 = 20(1. 046) - 2 = 18. 92

Length of AC = 25x = 25* 1.046 = 26. 15

The measure of angle A is 144.3 degrees and the angle to cut the molding is 54.3 degrees

Start by solving the acute part of angle A using the following sine function

sin(Ax) = (30 - 4)/32

Evaluate the quotient

sin(Ax) = 0.8125

Take the arc sin of both sides

Ax = 54.3

The measure of angle A is then calculated as:

A = 90 + Ax

This gives

A = 90 + 54.3

Evaluate

A = 144.3

Hence, the measure of angle A is 144.3 degrees

In (a), we have:

Ax = 54.3

This represents the angle where the molding would be cut

Hence, the angle to cut the molding is 54.3 degrees

F(x) = 21  10 10  8  9  5  6

What is line?
line, is curve showing the shortest distance between 2 points.

Now, putting x = 18 in f(x) ≈ −0.86x + 13.5
f(x) ≈ −0.86(18) + 13.5

a. The expression for profit is p(x) = -0.5x² + 40x - 300

b. The two values of x that will create a profit of $300 is 20 and 60

c. it is not possible for the company to make a profit of $15,000

The profit is the selling price minus the cost price.

Therefore,

Profit = revenue - cost

a.

The expression for profit is as follows;

p(x) = 90x − 0.5x² - (50x + 300)

p(x) = 90x − 0.5x²  - 50x - 300

p(x) = -0.5x² + 40x - 300

b.

The two values of x that will create a profit of $300 is as follows;

-0.5x² + 40x - 300 = 300

-0.5x² + 40x - 600 = 0

0.5x² - 40x + 600 = 0

x² - 80x + 1200 = 0

(x - 20)(x - 60)  = 0

x = 20 and 60

Therefore, the two value of x are 20 and 60

c.

-0.5x² + 40x - 300  = 15000

-0.5x² + 40x - 300 - 15000 = 0

-0.5x² + 40x - 15300 = 0

x² - 80x + 30600 = 0

Answer:

  80.7 mph

Step-by-step explanation:

In order to catch the car at the exit, the officer must cover the distance in 30 seconds less time than the car does. The time, speed, distance relation can be used.

The relation between time, speed, and distance is ...

  time = distance/speed

Here, speed is in miles per hour, and distance is in miles. That means time will be given in hours by the straightforward application of this formula.

  time = (3.6 mi)/(68 mi/h) = (3.6/68) h = 9/170 h

There are 3600 seconds in 1 hour, so 30 seconds represents this fraction of 1 hour:

  30/3600 = 1/120

The motorcycle will have this amount of time less than the time the car takes to reach the exit, so ...

  (9/170 -1/120) h = (9(120)-170)/(170×120) h = 910/20400 h = 91/2040 h

The speed required to cover 3.6 miles in 91/2040 hours is ...

  speed = distance/time

  (3.6 mi)/(91/2040 h) = 3.6×2040/91 mph = 7344/91 mph ≈ 80.7 mph

The officer's average speed in pursuit must be 80.7 miles per hour (or faster).

__

Additional comment

There are other ways the problem can be worked. One of them is to consider the remaining distance the car must travel when the officer begins pursuit. That will be 3.6 mi less (1/120 h)(68 mi/h) = 17/30 miles. The ratio of the officer's speed to the car's speed will be the same as the ratio of the officer's miles to the car's miles: 3.6/(3.6 -17/30) × 68 mph ≈ 80.7 mph.

Intermediate values used in the calculations should be kept at full calculator precision. Rounding should only be done at the end. Here, the actual speed required is 80.7032967... mph, rounded down for the above result.

Using the x-intercept concept, the function has x-intercept of 4 when c = -2.

The x-intercepts of a function are the values of x when y = 0.

In this problem, the function is:

cx - 5y + 8 = 0.

When y = 0, we have that:

cx + 8 = 0

x = 4, hence:
