Mario has a business selling muffins. Let x be the price of a muffin. Then, the profit P for Mario’s business is given by p(x)=-100x2+350x-150 Choose the inequality that shows the business will make a positive profit.

Answers

Answer 1
Answer:

The first question's answer is:

0<-100x^2+350x-150

The second question "Look at the factorization shown below.

0 < –100x2 + 350x – 150

0 < –50(2x2 – 7x + 3)

0 < –50(2x – 1)(x – 3)

Select the range that Mario can choose from to price his muffins and make a positive profit.

The answer is:

$0.50 < x < $3.00

The dollar price of a 1,000.00 face value bond is 991.25. this bond is listed at...

Answers

Answer:

The answer is : The bond is listed at 99.125%.

Step-by-step explanation:

Given is - The dollar price of a 1,000.00 face value bond is 991.25.

So, the purchase price is $991.25 and the bonds are worth of $1,000.

Hence, the bond is listed at:

(991.25)/(1000)*100 = 99.125%

The bond is listed at 99.125%.

If the price is $991.25 and the value of the bond is $1,000, the bond is listed at:
(991.25)/(1000)= .99125 or 99.125 %

Solve the following system using the substitution method.9x + 8y = 15
-5x + 12y = -107

(x, y) = ( , )

Answers

x = (15 - 8y)/9

-5[(15 - 8y)/9] + 12y = -107

(-75/9) + (40/9) + 12y = -107

y = -8.59

x = [15 - 8(-8.59)]/9

x = 9.3
(x,y) = (9.3, -8.59)

Let f(x) = x – 4 and g(x)=1/x. The graph of (g o f)(x) is shown below. What is the domain of (g o f)(x)?

all real numbers except x = –4
all real numbers except x = 0
all real numbers except x = 4
all real numbers

Answers

Answer:

domain is all real numbers except x=4

Step-by-step explanation:

f(x)= x-4 and g(x)=(1)/(x)

We need to find (gof)(x)

(g o f)(x)= g(f(x))

Plug in x-4 for f(x)

(g o f)(x)= g(f(x))=g(x-4)

Now we plug in x-4 for x in g(x)

(g o f)(x)= g(f(x))=g(x-4)=(1)/(x-4)

(g o f)(x)=(1)/(x-4)

Domain is the set of all x values for which the function is defined

To find out the x values that is undefined we set the denominator =0 and solve for x

x-4=0, x=4

When x=4 the denominator becoems 0 that is undefined

So domain is all real numbers except x=4

Oi-All real numbers except x=4 

they would all intersect 0 still

The manager of a sawmill wants to find out what percentage of the boards that the mill produced are defective.Which sampling methods are likely to be biased?

Choose all answers that are correct.

A.
The manager selects 20 boards at random each day for 5 days and examines them.

The manager sends an email to 20 customers who buy lumber from the mill, asking each how many of the boards they bought the past week were defective. Results from the first 5 customers to respond are tallied.

C.
On 1 day, an hour after the sawmill begins production, 30 boards in a row are selected and examined.

D.
Every 40th board produced over the course of 1 week is selected and examined.
