Answer: 2 times pi times the radius.

The radius is 1.155.

So the answer you will get is 7.25.

the answer would be 7.3 if you want to round it up.

Step-by-step explanation:

If you want to make the pi into your calculator just press shift and press the bottom middle where it has the x10x sign. That is how you get pi.

12x-9=10x-15 Help me answer this please

zvonat [6]

Answer:

x = -3

Step-by-step explanation:

Given:

12x - 9 = 10x - 15

Now, let's add 15 to both sides of the equation.

12x + 6 = 10x

Now, let's subtract 12x from both sides of the equation.

6 = -2x

Now, let's divide both sides by -2.

-3 = x

What is the probability that the system does not have a type 2defect?b.What is the probability that the system has both type 1 a

Lana71 [14]

Answer:

a. 0.93 b. 0.06 c. 0.05

Step-by-step explanation:

Probability is commonly known as the chance of success of a particular event. The probability of failure of the event can also be estimated.

(a) Probability of not having type 2 defect is: $P(A_{2}^{'})$ $= 1 - P(A_{2})$ = 1 - 0.07 = 0.93

(b) Probability of having type 1 and 2 defects is: $P(A_{1} n A_{2}) = P(A_{1}) + P(A_{2}) - P(A_{1}U A_{2}) = 0.12 + 0.07 - 0.13 = 0.06$

$P(A_{1} + A_{2} + A^{'} _{3}) = P(A_{1} n A_{2}) - P(A_{1} n A_{2} n A_{3}) = 0.06 - 0.01 = 0.05$

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
