Answer:

The company should not make 300 bicycles.

Step-by-step explanation:

Mathematically speaking, profit ([tex]P(y)[/tex]) equals the difference between revenue ([tex]R(y)[/tex]) and cost ([tex]C(y)[/tex]). That is:

[tex]P(y) = R(y) - C(y)[/tex] (1)

If we know that [tex]R(y) = 2\cdot y^{2}+10\cdot y + 500[/tex] and [tex]C(y) = y^{2}+10\cdot y+100000[/tex], then the profit function is:

[tex]P(y) = 2\cdot y^{2}+10\cdot y +500 -y^{2}-10\cdot y -100000[/tex]

[tex]P(y) = y^{2}-99500[/tex] (2)

The company can make the required amount of bicycles if and only if [tex]P(y) > 0[/tex]. If [tex]y = 300[/tex], then the profit of company is:

[tex]P(300) = 300^{2}-99500[/tex]

[tex]P(300) = -9500[/tex]

The company should not make 300 bicycles.

Answer:

a.)

Statement - If x and y are a pair of consecutive integers, then x and y have opposite parity.

Contra-positive statement - If x and y have same parity, then x and y can not be a pair of consecutive integers.

Assumed - x and y have same parity

To prove -  x and y can not be a pair of consecutive integers.

Contradiction statement - If x and y are a pair of consecutive integers and they have same parity then then it is not possible.

Assumed - x and y are a pair of consecutive integers and they have same parity

To prove - It is not possible

Proof - Let x and y are even numbers

⇒x = 2a , y = 2b

then , y - x = 2b - 2a = 2(b - a) is alteast 0 if x ≠y

Contradiction.

b.)

Statement - For all integers n, if n² is odd, then n is also odd.

Contrapositive statement - If n is even , then n² is even

assumed - n is even

To prove - n² is even

Contradiction - If n² is odd and n is even then it is not possible

Assumed - n² is odd and n is even

To prove - Our assumption is not true

Proof - As n is even

⇒n = 2a

⇒n² = (2a)² = 4a²

⇒n² is even

Contradiction.

Answer:

3:4

Step-by-step explanation:

This ratio can be written as 15/20. 15 and 20 are both divisible by 5 so if you simplify this fraction by dividing both numbers by 5 you get 3/4 or 3:4.

Answer:

C  89a + 2c)

Step-by-step explanation:

The largest factor of both 8 and 16 is 8.  So, 8 = GCF

factor out an 8 and you get 8(a + 2c)

To check if you are correct, multiply and see if you get what you started with.

Answer

Step-by-step explanation:   your answer would be -42  so heres how i did it: Evaluate for a=−5,c=−1

(8)(−5)+(2)(−1)

(8)(−5)+(2)(−1)

=−42

Answer:

x = 3

Step-by-step explanation:

Add 1 on both sides.

We get:

-2x = -6

Now divide -6 by -2...

-6/-2 = 3

-2x -1 = -7

add the "-1" on both sides, -2x -1 +1 = -7 +1

-2x = -6

divide "-2" on both sides, -2x/-2 = -6/-2

x = 3

Answer:

330

Step-by-step explanation:

A=a + b / 2 x h

a = 24, b = 20, h = 15

24 + 20 divided by 2 times 15

44 divided by 2 time 15

22 times 15 = 330

Answer:

W is either -22.5, or less than -22.5

Step-by-step explanation:

-9>=2/5 times w (I wasn't sure what you meant by "and" 9. Like 9w?)

W has to be a negative number, or else it would be greater than 9, which would make the equation wrong.

2/5 times -22 1/2=-9. So w can be -22 1/2 or -22.5

W can then be anything "lower" (on the left side) of -22.5.

W<-22.5

I've already answered this but

Answer:

Events A and B are dependent

Step-by-step explanation:

If A and B are two events such as A and B are dependent then

P(A∩B) [tex]\neq[/tex] P(A) P(B)

An event A will occur with probability 0.4 that is [tex]P(A)=0.4[/tex]

An event B will occur with probability 0.6 that is [tex]P(B)=0.6[/tex]

[tex]P(A)P(B)=0.4(0.6)=0.24[/tex]

The probability that both A and B will occur is 0.20 that is P(A∩B) = 0.20

Therefore,

P(A∩B) [tex]\neq[/tex] P(A) P(B)

So,

events A and B are dependent

According to the given probabilities, it is found that events A and B are dependent.

Two events, A and B are independent, if:

[tex]P(A \cap B) = P(A)P(B)[/tex]

In this problem, the probabilities given are:

[tex]P(A) = 0.4, P(B) = 0.6, P(A \cap B) = 0.2[/tex]

The multiplication is:

[tex]P(A)P(B) = 0.4(0.6) = 0.24[/tex]

Since [tex]P(A)P(B) \neq P(A \cap B)[/tex], the events A and B are dependent.

Answer:

20%

Step-by-step explanation:

40 pieces total

32 pieces eaten

40 - 32 = 8

8 pieces not eaten

Percentage = (part / whole) x 100%

Percentage = (8 / 40) x 100% = 0.2 x 100%

Percentage = 20%

Answer:

Step-by-step explanation:

In order to divide fractions, you'll have to multiply the first number by the second number's reciprocal.

So it would be 1 4/5 times the reciprocal of 2 7/10.

Reciprocal of 2 7/10 = Reciprocal of 27/10 = 10/27.

So 1 4/5 x 10/27 = 2/3

Answer:

2/3

Step-by-step explanation:

1 4/5 ÷ 2 7/10

Convert these into improper fractions

(Denomintaor × whole number + numerator)/denoninator

(5 × 1 + 4)/5

9/5

(10 × 2 + 7)/10

27/10

Now the equation says:

9/5 ÷ 27/10

Use the method copy dot flip, meaning rewrite the first fraction, change the division sign to multiplication, and use the reciprocal of the last fraction

9/5 × 10/27

Multiply the numerators and denominators separately

(9 × 10)/(5 × 27)

90/135

Simplify

Both 90 and 135 can evenly fit 15

90 ÷ 15 = 6

135 ÷ 15 = 9

6/9

This can still be simplified further

Both 6 and 9 can evenly fit 3

6 ÷ 3 = 2

9 ÷ 3 = 3

2/3

This cannot be simplified any further
