You have 50 ft of fencing and want to fence in a rectangular area of 144 ft^2. What are going to
be the dimensions of the rectangular area?
Quadratic equation

Answer: 0.2592

Step-by-step explanation:

This is conditional probability because the events are dependent on one another. You use multiplication rule 2(for dependent events) to solve this problem. The rule goes as follows: “When two events are dependent, the probability of both occurring is: p(A and B) = p(A) * p(B|A)” So all you would do is plug in. p(Sports and Instruments) = p(sports) * p(instruments)

p(Sports and Instruments) = (18/25) * (9/25) = 162/625 = 0.2592

The probability that a student who plays an instrument also plays a sport is 0.2592

The given parameters are:

Total = 25

Instrument = 9

Sport= 18

None = 3

The probability that a student plays a sport is:

P(Sport) = 18/25

The probability that a student plays an instrument is:

P(Instrument) = 9/25

The required probability is:

P = 18/25 * 9/25

Evaluate

P = 0.2592

Hence, the probability is 0.2592

$151.34

Step-by-step explanation:

You would do 138.72 minus 45.23.

138.72 minus 45.23 is 93.49.

Then, you would do 93.49 minus 18.

93.49 minus 18 is 75.49.

Now, you would add 75.49 and 75.85 together to get the answer.

75.49 + 75.85 = 151.34

260 cities

Step-by-step explanation:

Multiple 5 and 52

James would visit 260 cities in one year.

Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.

Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.

Given:

1 year = 52 weeks

James visits 5 cities per week.

To find the number of cities in e one year:

Multiply by 52

52 x 5

= 260 cities.

Therefore, he would visit 260 cities.

The polynomial cannot be factored with rational numbers.

Given:

The table of values.

To find:

The domain and range.

Solution:

The set of input values or x-values are known as domain.

In the given table, possible values of x are 1, 3, 5 and 9. So,

Domain = {1, 3, 5, 9}

The set of output values or y-values are known as range.

In the given table, possible values of y are 2, 4 and 7. So,

Range = {2, 4, 7}

Therefore, Domain = {1, 3, 5, 9} and Range = {2, 4, 7}.

Answer: 26.55°C

Step-by-step explanation:

Average daily maximum temperature in Syracuse = 21.85°C

Average daily minimum temperature = -4.7°C

In order to solve the question, we calculate the difference between the two temperature given. This will be:

= 21.85°C - (-4.7°C)

= 21.85°C + 4.7°C

= 26.55°C

Answer:

2/9 x 2/9 = 4/81

The probability that it rains two days in a row is 4/81 or 4.93% if it rains 2 out of 9 days in Austin, Texas.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.

We have:

It rains 2 out of 9 days in Austin, Texas.

P(r) = 2/9

So the probability that it rains two days in a row = (2/9)(2/9)

= 4/81

= 4.93%

Thus, the probability that it rains two days in a row is 4/81 or 4.93% if it rains 2 out of 9 days in Austin, Texas.

Answer: Only Kayla

Step-by-step explanation: i took the test

Kayla states correct statement that Andy is constructing the inscribed circle of the triangle.

Constructing the circumscribed circle of triangle ABC,

So that would be a circle that touches vertices the three vertices of the triangle .

We can construct using it using a compass and a straight edge, or a virtual compass and a virtual straight edge .

So what we want to do is center the circle at the perpendicular bisectors of the sides or sometimes that's called the circumcenter of the triangle.

To construct where the perpendicular bisectors of the sides are ,So let me put a circle over here whose radius is longer than this side right over here .

Now let get one that has the same size so let make it the same size as the one i just did.

And allow to construct a perpendicular bisector. If go through that point and this point right over here, this bisect the side over here, and its at a right angle.

Now lets do that for the other sides,  if i move this over here and  I really just have to do it for one, of the other sides.

Because the intersection of two lines is going to give a point . so can do it for this side right over here.

So let me add a other straight edge right over here. so going to go through the point , so that's the perpendicular bisector. of the side right over here. and i could do the third side and it should intersect at that point .

I am not ultra , ultra precise but closing enough. and now i just have to center one of these circle .

And move the circle to the circumcenter and adjust its radius so that its get close to touching .

The three sides the three vertices of the triangle ABC .

Kayla state that Andy is constructing the inscribed circle of the triangle . This is the correct.

Answer:

Step-by-step explanation:

Equation of a line giving 2 points is

y-y1=m(x-x1) where m is the slope and (x1,y1) is one of the points.

First we have to find the slope using formula

(y2-y1)/(x2-x1) where (x1,y1) and (x2,y2) are the points given

Slope m is (4-13)/(8--4) =-9/12 = -3/4

Answer:

  3x + 2y = 0   or   y = -3/2x

Step-by-step explanation:

The relationship between a line and its perpendicular is that their slopes are opposite reciprocals of each other. So, the thing you need to know about the line through the two given points is its slope. That is found using the slope formula:

  m = (y2 -y1)/(x2 -x1) . . . . . . where the two give points are (x1, y1) and (x2, y2)

Putting your point coordinates in this formula gives ...

  m = (5 -3)/(5 -2) = 2/3

Then the perpendicular line will have a slope that is the opposite reciprocal:

  slope of perpendicular = -1/m = -1/(2/3) = -3/2

You have not said whether the perpendicular line must meet any other requirement, so the simplest one we can write is ...

  y = mx + b . . . . . m is the slope and b is the y-intercept

  y = -3/2x . . . . . . has a y-intercept of 0 (goes through the origin)

Multiplying by 2 and adding 3x gives ...

  3x + 2y = 0 . . . . . standard form equation

Comment on the attachment

The geometry program I used to create the attachment wrote the equation of the line through the given points as ...

 2x -3y = -5 . . . . . standard form equation

The equation of a perpendicular line can be created from this form by swapping the x- and y-coefficients and negating one of them. Simply swapping the coefficients would give ...

  -3x +2y = <something>

In standard form, we want the leading coefficient to be positive, so we can choose to negate the x-coefficient. The <something> can be zero to make the line go through the origin.

  3x +2y = 0 . . . . . a perpendicular in standard form

__

If you need to have the line go through a particular point, you can determine the constant value (on the right of the = sign) by putting the point coordinates in for x and y.
