Answer:

Step-by-step explanation:

(4x-8)+36 = 180

4x - 8+36 = 180

4x +28 = 180

4x = 180-28

4x = 152

x = 152/4

x = 38

A manufacturer produces televisions. He estimates that by selling them for x dollars each, he will be able to sell 230 – 3x each

poizon [28]

Answer:

Price per television =38.30

Step-by-step explanation:

Number of units sold in one week =230-3x

Price of one unit =x

Total money produced in one week =x(230 - 3x)

(Here it doesn't matter total money is taken for a week or day because after differentiating and equating to zero that factor disappear )

Differentiate total amount with respect to x.

$\frac{dM}{dt}=230-6x$

Now equate it equal to zero to get extremum.

230-6x=0

Then, x = 38.30

Subtract the following polynomials. Write answer in a-b-c-d order. From 4a+7b-12c subtract 8a-9b+12d

ozzi

$(4a+7b-12c)-(8a-9b+12d)\\4a+7b-12c-8a+9b-12d$

Negative multiply negative = Positive

Negative multiply positive = negative

$-8a+4a+9b+7b-12c-12d\\-4a+16b-12c-12d$

Thus the answer is -4a + 16b - 12c - 12d.

A coin is tossed and an eight-sided die numbered 1 through 8 is rolled. Find the probability of tossing a head and then rolling

ratelena [41]

Answer: 7/8

Step-by-step explanation:

Probability is calculated by number of possible outcomes/ total outcomes

From the question, a coin only has two sides, Head or Tail. Total outcomes is therefore equal to 2

Possible outcome is to toss a head, which is one event

Probability of tossing a head is therefore =1/2

The second part of the question is rolling a die with eight sides.

Here, the die is said to have eight sides, 1,2,3,4,5,6,7,8. Total outcomes is therefore equal to 8

Possible outcome of rolling a number greater than 5 is 3 possibilities, that is rolling 6, 7 and 8.

Pr(rolling > 5) is 3/8

Therefore, Pr ( head; rolling > than 5)

= 1/2 + 3/8

=7/8

I hope this is clear, please mark as brainliest answer
