What is mean by Fraction?

A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.

Given that;

On Friday night, Cassie ate a pizza for dinner and had 5/6 of the pizza left over.

And, On Saturday, she ate 1/3 of what was left.

Now,

Since, On Saturday, she ate 1/3 of what was left.

Hence, The amount of the pizza did Cassie eat on Saturday is;

⇒ 5/6 - 1/3 of 5/6

⇒ 5/6 - 1/3 × 5/6

⇒ 5/6 - 5/18

⇒ 15/18 - 5/18

⇒ 10/18

⇒ 5/9

Thus, The amount of the pizza did Cassie eat on Saturday will be 5/9 of pizza.

Answer:

It will take Iliana 16 hours to get 200 total XP.

Step-by-step explanation:

To project a value on a graph, we need to first find the equation of the graph.

The graph makes the shape of a line. Therefore, the equation of a graph is a linear equation.

⭐What is a linear equation?

To make the equation for this graph, we need to find the value of the slope and the y-intercept and substitute it into the equation.

The equation for this graph will be called P(t).

⭐How do we find the slope?

Pick 2 coordinates you are given. I am going to use (2,25) and (4,50).

Substitute these coordinates into the slope formula.

[tex]m = \frac{y_2-y_1}{x_2-x_1}\\\\[/tex]

[tex]m = \frac{50-25}{4-2}[/tex]

[tex]m = \frac{25}{2}[/tex]

⭐How do we find the y-intercept?

Since we aren't given the corresponding y-value for when x=0, we have to do the second option stated.

m = 25/2 is the same thing as m = -25/-2, because:

negative/negative = positive

positive/positive = positive

Thus, we can move down from point (2,25) 25 units and left 2 units to get to point (0,0).

[tex]y-intercept = 0[/tex]

Now, substitute the values of the y-intercept and the slope into the equation for the graph.

[tex]P(t) = mt + b[/tex]

[tex]P(t) = \frac{25}{2}t[/tex]

Next, to project a value on the graph, we need to substitute the y-value into the equation to find its corresponding x-value.

The y-value we want to find is 200 XP.

[tex]200 = \frac{25}{2}t[/tex]

Multiply LHS and RHS by [tex]\frac{2}{25}[/tex] to isolate t.

[tex]\frac{2}{25}(200) = \frac{2}{25}(\frac{25}{2}t)[/tex]

[tex]\frac{400}{25} = t[/tex]

[tex]16 = t[/tex]

∴ It will take Iliana 16 hours to get 200 total XP!

p=12.5t you could make (t) time by itself

t = p/12.5

HOW LONG TO GET 200 XP

you need t get the value of t cause p = to 200

t= p/12.5

a)The probability that the next household on the list will be contacted but will refuse to cooperate will be 0.38

b)The probability of failing to contact a household or of contacting the household but  will refuse to cooperate is  0.62.

We are given the information that interviewers can reach about 76% of U.S. households, the percentage of those contacted who agree to cooperate with the survey fell from 58% in 1997 to only 38% in 2003.  To calculate these probabilities, we use the cooperation rate from 2003. Since the cooperation rate is 38%, this means that 38% of the people will cooperate and 62% will not cooperate. Therefore, the probability of the next household on the list not cooperating is 0.62 and the probability of the next household on the list cooperating is 0.38.

The probability that you exit the row from the front rather than the back is 1/2.

The probability is calculated by dividing the total number of outcomes by the number of possible ways the event could occur. Probability and odds are two separate ideas. Odds are the possibility of something happening divided by the likelihood that it won't happen.

A probability is a number that expresses the possibility or likelihood that a specific event will take place. In addition to being expressed as percentages ranging from 0% to 100%, probabilities can also be expressed as proportions between 0 and 1.

To factor P(x) without grouping, substitute

x = -1, 1, -2, 2, -3, 3.......

P(-1) = 0 ----> (x + 1) is a factor of P(x)

P(1) = 0 ----> (x - 1) is a factor of P(x)

P(2) = 0 ----> (x - 2) is a factor of P(x)

If P(-1) ≠ 0, then (x + 1) is not a factor of P(x).

Then, try x = 1, x = -2, x = 2 and so on.

Once one of the linear factors of P(x) is found, the other factors can bound easily (the rest of the process has been explained in the following examples).

Factor the following polynomials without grouping :

A segment is essentially the area of a circle between the chord and the arc. A circle is a path that a point equidistant from a single point on the plane can follow; this point is known as the circle's center, and the distance between it and that point is known as the circle's radius. A segment is a section of a circle's interior. A sector is the region that a segment encloses and the angle that a segment occupies. By deducting the triangle produced inside the sector from the sector that contains the segment, one can calculate the area of a circular segment.

The area of a section that made by a circle is ∏ r² × (θ/360).

a) The marginal cost MC at  x=9 units is $154.70.

b) The cost of producing 1 additional unit is $154.70.

c) The cost of producing 2 additional units is $309.40.

The Marginal Cost quantifies the incremental cost incurred from the production of each additional unit of a good or service. The marginal cost of production captures the additional cost of producing one more unit of a good/service.

The analysis of the marginal cost helps determine the “optimal” production quantity, where the cost of producing an additional unit is at its lowest point. The marginal cost of production must be lower than the price per unit for a company to be profitable – thus, the marginal cost pinpoints the output volume and pricing where incremental costs are reduced.

a) Marginal Cost = (Change in Costs) ÷ (Change in Quantity)

C(x) = 1/90[tex]x^{3}[/tex] + 8[tex]x^{2}[/tex] + 8[tex]x[/tex] +18

MC = dC/dx

MC = d( 1/90[tex]x^{3}[/tex] + 8[tex]x^{2}[/tex] + 8[tex]x[/tex] +18) / dx

      = 1/90 (3x²) + 8 (2x) + 8

      = 1/30x² + 16x + 8

At x = 9 units, we get

MC(x=9) = 1/30 (9²) + 16 (9) + 8

              = 154.7

Rounding off to two decimal places, we get 154.70.

Thus, the marginal cost MC at  x=9 units is $154.70.

b) Marginal Cost = (Change in Costs) ÷ (Change in Quantity)

154.70 = Change in costs/ 1

Change in costs = 154.70

So, the cost of producing 1 additional unit is $154.70.

c) Marginal Cost = (Change in Costs) ÷ (Change in Quantity)

154.70 = Change in costs/ 2

Change is costs = 309.40

So, the cost of producing 2 additional units is $309.40.
