A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the
defon

Answer:

Price of widget to break even= $37.9

Step-by-step explanation:

We are told that the equation representing the amount of profit, y, made by the company, in relation to the selling price of each widget, x is;

y = -8x² + 348x - 1705

Now, the company will break even when it has made no profit. That is when, y = 0

Thus;

0 = -8x² + 348x - 1705

Rearranging,

8x² - 348x + 1705 = 0

Using quadratic formula ;

x = [-b ± √(b² - 4ac)]/2a

x = [-8 ± √(-348² - 4•1•1705)]/(2 x 8)

x = $5.63 or $37.87

We'll use $37.87 because it is the highest price for which no profit is made, and higher price means that we could sell least number of products to earn a certain amount of money.

We are told to approximate to nearest cent. Thus,

Price of widget = $37.87 ≈ $37.9

What is the value of x, when -9(x-5)=x+22 1/2​
Kipish [7]

Answer:

x = 2.25

Step-by-step explanation:

 -9(x - 5) = x + 22 1/2

Distribute the nine and then add 9x to both sides

 -9x + 45 = x +22 1/2

+ 9x        + 9x

Then try to get x alone

       45 = 10x + 22 1/2

     -22 1/2       -22 1/2

    22.5 = 10x

   \frac{22.5}{10} = \frac{10x}{10}

   2.25 = x

A and B are two events. Let P(A)=0.5 , P(B)=0.9 and P(A and B)=0.15 .
Nana76 [90]

Answer:

option-C

Step-by-step explanation:

we are given

Let P(A)=0.5

P(B)=0.9

P(A and B)=0.15

we know that

P(A|B)=\frac{P(Aand B)}{P(B)}

now, we can plug values

P(A|B)=\frac{0.15}{0.9}

P(A|B)=0.16666

but we have

P(A)=0.5

we can see that both are not equal

P(A|B)\neq P(A)

so, A and B are not independent

so, option-C........Answer
