Answer:

C/d = 31.4/10

Step-by-step explanation:

We know the formula of the circumference, which ir:

C = pi*d

Where C is the circumference and d is the diameter of the circle. If we want to know the value of the pi number we just need to divide both sides of the equation above by d:

C/d = pi*d/d

C/d = pi

Thus, we can write pi as the ratio C:d or C/d, which means, how many times the diameter enters on the circumference. In our case is:

pi = 31.4/10 = 3.14

And 3.14 is how we usually use the pi number.

F 100 tires are randomly selected for shipment to an outlet what is the probability that they are all​ good?
sergeinik [125]
<span>Lets calculate an example: Say, .001% of tires that come from the factory are bad. There is a 1/1000 chance that for any given tire randomly selected from the warehouse that a defect will be present. Each tire is a mutually exclusive independently occurring event in this case. The probability that a single tire will be good or bad, does not depend on how many tires are shipped in proportion to this known .001% (or 1/1000) defect rate. To get the probability in a case like this, that all tires are good in a shipment of 100, with a factory defect rate of .001%, first divide 999/1000. We know that .999% of tires are good. Since 1/1000 is bad, 999/1000 are good. Now, multiply .999 x .999 x .999..etc until you account for every tire in the group of 100 shipped. (.999 to the hundredth power) This gives us 0.90479214711 which rounds to about .90. or a 90% probability. So for this example, in a shipment of 100 tires, with a .001% factory defect rate, the probability is about 90 percent that all tires will be good. Remember, the tires are mutually exclusive and independent of each other when using something like a factory defect rate to calculate the probability that a shipment will be good.</span>

Which is different?
Alja [10]

A) Solve 3x+6y=24 for x.

Subtracting 6y from both sides, we get

3x+6y-6y=24-6y

3x = -6y+24

Dividing both sides by 3, we get

\frac{3x}{3} = \frac{-6y}{3} +\frac{24}{3}

x= -2y + 8

b) Solve 24−3x=6y for x.

Subtracting 24 from both sides, we get

24-24−3x=6y-24

-3x = 6y -24.

Dividing both sides by -3, we get

\frac{-3x}{-3} =\frac{6y}{-3} -\frac{24}{-3}

x= -2y + 8.

c) Solve 6y=24−3x for y in terms of x.

Dividing both side by 6.

\frac{6y}{6} =\frac{24}{6}- \frac{3x}{6}

y= -\frac{1}{2}x+4

d) Solve 24−6y=3x for x in terms of y.

Dividing both sides by 3, we get

\frac{24}{3} - \frac{6y}{3} = \frac{3x}{3}

8 - 2y = x.

x = -2y +8

<h3>Therefore, x=-2x+8 and y=-\frac{1}{2}x+4.</h3>

URGENT. Geometric Probability.
hichkok12 [17]

Answer:

Hello,

Step-by-step explanation:

heigth of the equilateral triangle:

h=3*\dfrac{\sqrt{3}}{2}

Area of the triangle:

A=\dfrac{6*3\sqrt{3} }{2*2} =\dfrac{9\sqrt{3} }{2} \\\\

Area of the disk:

S=\pi*4^2=16\pi\\\\

Probability:

p=\dfrac{9\sqrt{3} }{2*16*\pi}=0.15506125....\approx{15.5\%}
