Step-by-step explanation:

According to Yaseen's demand function, if she can produce 60 kits, the function cost per kit should be set at:

[tex]p = 30 - 0.5q\s60 = q = > p = 30 - 0.5(60) (60) > p = $15[/tex]

Probability theory is an area of mathematics that deals with calculating the likelihood that an event will occur or a proposition will be true. A risk is a number between 0 and 1, where 0 represents the possibility of an event occurring and 1 represents certainty.

Probability is a mathematical expression of the possibility that an event will occur. The proportion of equally plausible options that actually occur relative to all potential outcomes when an event happens is known as the probability, and it may also be written as an integer between 0 and 1.

According to Yaseen's supply function, if she can produce 15 kits, the cost per kit she should charge is:

[tex]p = 10 + 0.5q[/tex]

[tex]p = 10 + 0.5(15) (15)[/tex]

[tex]p = $17.50[/tex]

According to Yaseen's demand function, if she can produce 15 kits, the cost per kit she should charge is:

[tex]p = 30 - 0.5q\sp = 30 - 0.5(15) (15)[/tex]

[tex]p = $22.50[/tex]

According to Yaseen's supply function, if she can provide 60 kits, the cost per kit should be as follows:  [tex]p = 10 + 0.5q 60 = q p = 10 + 0.5 (60)[/tex]

[tex]p = $40[/tex]

According to Yaseen's demand function, if she can produce 60 kits, the cost per kit should be set at:

[tex]p = 30 - 0.5q\s 60 = q[/tex]

[tex]p = 30 - 0.5(60) (60)[/tex]

[tex]p = $15[/tex]

Answer:

Step-by-step explanation:

1. Demand- 0<=x<=85 /  Supply- 0<=x<=100

The company is estimating that no more then 85 kits will be demanded each month. The company can supply no more then 100 kits per month.

2. x=15

S(15)=0.01(15)^2+0.5(15)=9.75

D(15)=0.02(15-100)^2=144.5

3. x=60

S(60)=0.01(60)^2+0.5(60)=66

D(60)=0.02(60-100)^2=32

4. The supply in question 3 is larger then the demand. Supply>Demand- No, because the demanding price is much lower.

5. X^2- Quadratics because in math the quadratic equation of degree 2 is the highest exponent of the equation with the standard as y=ax^2+bx+c

6. See attachment

7. f(x)=0.02(x-100)^2      g(x)=0.01x^2+0.5x

They intersect on the graph at (50, 50) so the products is 50.

8. See Attachment

f(x)=0.02(x-100)^2

g(x)=0.01x^2+0.5x

If the length of OB was 3/4, then the length of OB' after dilation is; Option B: 3 units.

Dilation of an object simply means enlarging or shrinking the object by a scale factor.

We are told that Triangle ABC was dilated to Triangle A'B'C' using the rule D₀,₄. What this means is that it was enlarged by a scale factor of 4 with point O as the centre of dilation.

Now, if the length of OB is 3/4, it means that the new dilated length is gotten from;

                    Scale factor = new dilated length OB'/(3/4)

                    New dilated length OB' = (3/4) × 4

                    New dilated length OB' = 3 units

The question is incomplete. The complete question:

"Triangle ABC was dilated using the rule DO,4. Triangle A'B'C' is the result of the dilation. Point O is the centre of dilation. Triangle A B C is dilated to create triangle A prime B prime C prime. The length of O B is three-fourths. What is OB'?"

The simplified expression by using box method to distribute is [tex]5x^2 - 6x - 8.[/tex]

In mathematics, an expression is a combination of symbols, numbers, and operators (such as +, -, x, ÷, etc.) that represents a quantity or a relationship between quantities. Expressions can be simple, such as a single number or variable, or complex, such as an algebraic expression with multiple terms and variables. Expressions can be evaluated, simplified, and manipulated using various algebraic techniques.

To use the box method, we draw a box and divide it into four parts, with each part representing a multiplication of one term from the first expression with one term from the second expression:

We then add up the terms in each box to simplify:

(5x + 4)(x - 2) = [tex]5x^2 - 10x + 4x - 8[/tex]

Answer:

24%

Step-by-step explanation:

It’s easy all u have to do is add the 95% and 15%

And when u get the answer u add it with 1.10$ and boom u subtract the number and u get 24%.

Answer: $1.80 and $11.40

Step-by-step explanation:

We know that Chris was short on cash by $1.20, but we need to create an equivalent percentage.

95% + 15% = 110% (how much does it cost)

110% - 110% (how much he had) = 10% (amount short) = $1.20

10% = $1.20

100% (how much he had) = $12.00

Mouse = 95% of $12.00 (how much he had) = $11.40

Mouse pad = 15% of $12.00 (how much he had) = $1.80

Check your work:

$1.80 (Mouse pad) + $11.40 (Mouse) = $13.20

$13.20 - $12.00 = $1.20 (amount short)

We were correct!

Final Answer: $1.80 and $11.40

The QS would be QS = PQ(1 + PQ/13)

What are the sides and angles of a parallelogram?

S = (n 2) 180°, where 'n' specifies the number of sides in the polygon, can also be used to determine this.

Since PQRS is a parallelogram, opposite sides are parallel and equal in length. Therefore, we can say that PQ = SR and QS = PR.

If QX = 13, then we can use the fact that PQRS is a parallelogram to find the length of QS. We can draw a line segment from Q that is parallel to SR, and call the point where this line segment intersects PS as Y. This forms two triangles, QXY and QSR, which are similar because they share an angle and have parallel sides.

By the properties of similar triangles, we can set up a proportion:

QY/QX = QS/SR

Since QY is the same as PS, we can substitute PQ + QY for PS:

(QX + PQ)/QX = QS/SR

Substituting the value of QX and recognizing that PQ = SR, we get:

(13 + PQ)/13 = QS/PQ

Simplifying this equation, we get:

1 + PQ/13 = QS/PQ

Multiplying both sides by PQ, we get:

PQ + (PQ^2/13) = QS

Since PQ = SR and PQRS is a parallelogram, we know that SR = PQ, so we can substitute PQ for SR:

QS = PQ + (PQ^2/13)

Simplifying further, we get:

QS = PQ(1 + PQ/13)

Therefore, The QS would be QS = PQ(1 + PQ/13)

The reduced price of the piano is $301 if Lou went shopping for a piano at our ST store a piano originally priced at $860 had a price reduction of 65%

What is percentage ?

Percentage can be defined as the product of ratio of given value, total value and hundred.

To find the reduced price of the piano, we need to multiply the original price by the discount percentage (65%) and then subtract the result from the original price.

The amount of the discount is:

65% of $860 = 0.65 x $860 = $559

So, the reduced price of the piano after the discount is:

Reduced price = Original price - Discount

Reduced price = $860 - $559

Reduced price = $301

From trigonometric ratios, the value of x and y are 11 [tex]\sqrt{3}[/tex] and 11, respectively.

A triangle is classified as a right triangle when it presents one of your angles equal to 90º.  The greatest side of a right triangle is called the hypotenuse. And, the other two sides are called legs.

The math tools applied for finding angles or sides in a right triangle are the trigonometric ratios or the Pythagorean Theorem.

The Pythagorean Theorem says: (hypotenuse)²= (leg1)²+(leg2)² . And the main trigonometric ratios are: sin (x) ,  cos  (x) and tan  (x) , where:

sin (x) =[tex]\frac{opposite\ leg}{hypotenuse}[/tex]

cos(x)=[tex]\frac{adjacent\ leg}{hypotenuse}[/tex]

tan (x) = [tex]\frac{sin (x)}{cos(s)}= \frac{opposite\ leg}{adjacent\ leg}[/tex]

Therefore, for finding x you can apply the trigonometric ratio sin (x). See below:

sin (60) =[tex]\frac{opposite\ leg}{hypotenuse}=\frac{x}{22}[/tex], knowing that  sin (60)=[tex]\frac{\sqrt{3} }{2}[/tex] you have

[tex]\frac{\sqrt{3} }{2}=\frac{x}{22} \\ \\ 2x=22\sqrt{3} \\ \\ x=11\sqrt{3}[/tex]

Answer:

(5w - 3)(2w - 5)

Step-by-step explanation:

As this polynomial is of the form ax² + bx + c, where a = 10, b = -31, and c = 15 (and x = w), in this case, as a is a number other than 1, the first step is to multiply a and c, replacing c with that product and removing the coefficient from the w² term, giving us:

w² - 31w + 150 (as 10 × 50 is 150)

Now, we are looking for two numbers that when they're multiplied together you get c, which is 150, and those same two numbers when added together gives us b, -31.

After looking through all of the possible factors of 150, we see that -25 and -6 fulfill both of these requirements (as -25 × -6 = 150 and -25 + -6 = -31)

Now, as we have our two numbers we can set up our factors:

(w - 6)(w - 25)

However, as we had to get rid of the 10 in front of the w², we now have to bring it back in front of both w's, giving us:

(10w - 6)(10w - 25)

Now we look and see if we can simplify.

We can see that 10 and -6 can both be simplified by 2, giving us:

(5w - 3)(10w - 25)

We can also see that 10 and -25 can be simplified by 5, giving us:

(5w - 3)(2w - 5)
