The conclusion from the factor table of 18 is that, 18 is not a prime number i.e. it is composite

From the question, the number is given as

Number = 18

The factors of 18 are represented as

Factors of 18 = 1, 2, 3, 6, 9 and 18

When these factors are picked in pairs, we have the following  representations

Factors pairs of 18 = (1, 18), (2, 9), (3, 6)

Next, we represent the factors on a factor table

So, we have

Factors      Factor pairs        Prime factorization

1, 2, 3,           (1, 18)                       2 x 3²

6, 9 and        (2, 9)

18                   (3, 6)  

Because the number 18 has factors other than 1 and 18, then the number 18 is a composite number

Answer:

x = 50

Step-by-step explanation:

50 x 3 - 15 = 135

an octagon has 8 sides & 8 angles. 135 x 8 = 1,080 which is the amount of degrees an octagon equals.

Answer:

50

Step-by-step explanation:

Total angles in an octagon is 1080

Because there are 8 sides you must divide 1080/8 to find the angle of one side ... 1080/8 = 135

3x-15=135

1) 135+15 = 150

2)150/3=50

Step-by-step explanation:

Let me know if i got anything wrong!

The graph of y = 3x² + 7x + m will have two x-intercepts if m < 49/12.

The given function is,

y = 3x² + 7x + m

Having two x-intercepts means that the value of y should be 0.

So, we can write,

3x² + 7x + m = 0

Now, this has become a quadratic equation and it will have two zeroes according to the question,

As we know, the condition of quadratic to have two different values of x is,

0 < √(b²-4ac)

Where,

a = 3

b = 7

c =m

Putting all the values,

√(7²-4(3)(m)) > 0

Squaring both sides,

7²-4(3)(m) > 0

49-12m > 0

49/12 > m.

So, the graph will have two intercepts if m < 49/12.

The ratio of the width of the rectangle to the length of the rectangle is 10/13

We are provided with the rectangle. The dimensions of the rectangle are mentioned below;

Width of rectangle = 20

Length of rectangle = 26

We were asked to calculate the ratio of width of the rectangle to the length of the rectangle. So, to calculate the ratio of width of the rectangle to the length of the rectangle we need to divide the width of rectangle to the length of the rectangle as mentioned below;

( Width of rectangle/Length of rectangle ) = 20 / 26

( Width of rectangle/Length of rectangle ) = 10/13

So, we can finally conclude that the ratio of width of the rectangle to the length of the rectangle is 10/13 .

We will investigate how to graph a straight line on cartesian coordinate plane.

All equations of straight line are expressed in a general slope-intercept form as follows:

Where,

To graph any straight line we need the equation of the straight line or atleast two points that must lie on the line.

We are given the slope ( m ) and one of the points that lie on the line as follows:

We need one another point that lies on the line to plot the graph of a straight line. To find another point we must completely express the equation of the straight line ( general form given above ).

3/6 = 1/2

Solution

-3x +4y = 24 (1)

Central angle of 135 degrees = 135 (Pi/180) = (3/4)Pi = 2.356 radians

First answer:

Central angle = 2.356 radians

Arc lenght = 2 Pi r (angle/360), in this case:

82 = 2 Pi r (135/360) = 2 Pi r (3/8) = (3/4) Pi r

82 = (3/4) Pi r

r = 82/(3/4)Pi = 82/2.35619449

r = 34.80188089

a) the probability that event A occurs but event B does not occur = 0.33

b) the probability that either B occurs without A occurring or A and B both occur = 0.04

In this question, we have been given two mutually exclusive events A and B.

event A has probability 0.33 and the event B has probability 0.04

P(A) = 0.33 and P(B) = 0.04

We need to compute the probability that event A occurs but event B does not occur.

i.t., to find = P(A ∩ B')

We know that, P(A ∩ B') = P(A) - P(A ∩ B)

For mutually exclusive events, P(A ∩ B) = 0

So, P(A ∩ B') = P(A)

P(A ∩ B') = 0.33

Also, we need to compute the probability that either B occurs without A occurring or A and B both occur.

P(B ∪ A') + P(A ∩ B)

= P(B) + 0

= 0.04

Therefore, a) the probability that event A occurs but event B does not occur = 0.33

b) the probability that either B occurs without A occurring or A and B both occur = 0.04

The material with the lower density floats and the material having higher velocity sinks. As the density of glass is 2.40 [tex]g/cm^{3}[/tex]  which is larger than the density of water , so glass will sink in water. As the density of baby oil is 0.83 [tex]g/cm^{3}[/tex]  which is less than the density of water , so glass will float in water.

The room is a rectangle with dimensions 25 and x + 10. The area of a rectangle is the product of its dimensions, so the area will be:

We have to add the parenthesis because we first need to add 10 and x and then multiply. Distributing the 25, we have:

As we can see, this matches what Ron thinks the area will be, so he is correct. Thus, the answer is "Yes". The why can be both because the area is the sum of 25*10 and 25x and because the area is the product of 25 and 10 + x.

Part a: time when object hit the ground is 10.5 sec.

Part b: The height of the object 3 seconds is 1632 ft.

For the given question;

The equation that models the height f(t) (in feet) of an object t seconds after it is when dropped from the top of the tower is,

f(t) = -16t² + 1776

Part a: time when object hit the ground.

When the object hit the ground, height will be zero.

Put f(t) = 0.

0 = -16t² + 1776

-16t² = -1776

t² = 111

t = 10.5 sec.

The, time after which the object will hit the ground is 10.5 sec.

Part b: The height of the object 3 seconds;

Put t = 3 in the equation.

f(3) = -16(3)² + 1776

f(3) = 1632 ft

The height of the object after 3 sec will be 1632 ft.

Thus, the values for the object hitting the ground are found.

Here, we want to get the expression that is equivalent to the given expression

We have this as follows:

Now, we can rewrite the overall expression as:

Since we don't know the specific income of each person in the sample, we don't know for sure if the median will change. Nevertheless, the mean will surely raise.

Since the current average income is $10,000, if one of them gets a raise of $10,000, then the sum of all incomes would be $100,000+$10,000=$110,000. And the new average income will be:

Then, the mean increases by $1,000, and we can't say anything about the median.

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y=kx

A.

The question asks us to find the probability of getting at least 4 or an odd number after throwing a die.

This is easily gotten using the OR probability of two events which states:

To get at least 4, it means the possible values we can have are: 4, 5, 6.

To get an odd number, it means the possible values we can have are: 1, 3, 5.

From both set of possibilities, 5 is common. We need to subtract the probability of getting a 5 in both situations to prevent duplication.

Thus, we can compute each probability:

Therefore, the probability of getting at least 4 or an odd number is 5/6

B:

This part of the question asks us to find the probability of rolling an even number or a number at most 5.

We, once again, take a look at the possibilities to solve this question.

Possibilities of getting an even number are: 2, 4, or 6

Possibilities of getting at most 5 are: 1, 2 , 3, 4, 5.

Therefore, we can compute the probabilities as:

The linear equation in point-slope form of the given condition is y = 30x + 170. The number of words after 8 days will be 410.

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

Let's represent the number of days by x and the number of words by y.

At day 1 (x = 1) ⇒ Number of words (y = 200)

At day 1 (x = 2) ⇒ Number of words (y = 230)

The point-slope form of a linear equation is given as,

y = mx + c

Where m is the slope, while c is the y-intercept.

Substitute,(1,200) in y = mx + c

200 = m(1) + c

Now slope m = (230 - 200)/(2 - 1) = 30

200 = 30(1) + c

c = 170

Therefore, the equation become,

y = 30x + 170

The number of words after 8 days will be,

y = 30(8) + 170 = 410

Hence "The linear equation in point-slope form of the given condition is y = 30x + 170. The number of words after 8 days will be 410".
