Find the probability of having 2, 3, or 4

Mathematics
1 answer:
denis-greek [22]3 years ago
3 0

Answer:

16% for 2 successes, 6.4% for 3 successes, 2.6% for 4 successes, and 1% for 5 successes

Step-by-step explanation:

Since the success rate of a binomial experiment is 40%, converted to 0.4, you get the equation of f(x) = (0.4)^x, for where x is the amount of successful experiments

For the success of 2 experiments:

f(2) = (0.4)^2

     =0.16 => 16%

For the success of 3 experiments:

f(3) = (0.4)^3

     = 0.064 => 6.4%

For the success of 4 experiments:

f(4) = (0.4)^4

     = 0.0256 => 2.56% => ~2.6

For the success of 5 experiments:

f(5) = (0.4)^5

     = 0.01024 => 1.024% => ~1%

The terminal side of an angle in standard position passes through P(15, –8). What is the value of sine theta? sine theta = fifte
Pavlova-9 [17]

The value of sine theta = negative eight-seventeenths ⇒ 2nd

Step-by-step explanation:

Let us revise the quadrant of an angle its terminal side passes through a given point

  • If the given point is (x , y), then the angle lies in the 1st quadrant
  • If the given point is (-x , y), then the angle lies in the 2nd quadrant
  • If the given point is (-x , -y), then the angle lies in the 3rd quadrant
  • If the given point is (x , -y), then the angle lies in the 4th quadrant

∵ The terminal side of angle Ф passes through P (15 , -8)

∵ x = 15 and y = -8

- P is (x , -y), then the angle Ф lies in the 4th quadrant

∵ The terminal side of angle Ф is the hypotenuse of a right

   triangle whose horizontal leg is 15 units and vertical leg

   is -8 units

- Use Pythagoras Theorem to find the length of the hypotenuse

∴ Hypotenuse = \sqrt{(15)^{2}+(-8)^{2}}=17 units

∵ sinФ = \frac{opposite}{hypotenuse}

∵ The side opposite to Ф is -8

∵ The hypotenuse is 17

∴ sinФ = \frac{-8}{17}

The value of sine theta = negative eight-seventeenths

How many hours do they have to work before they go to the movies
lorasvet [3.4K]

Answer:

25 months

Step-by-step explanation:

Plan A : $70 per month

Plan B : $50 per month + $500 as a one time cost.  

So for A $70 a month would take 8 months to be at least $500

And for B it in those 8 months it would cost you $900

But we have to keep going up until they are equal

25*70 = 1750

(25*50) = 1250+500=1750

So yes 25 months is correct

What is the volume of this figure?
Olenka [21]
The formula for the volume of a cone is 1/3\pir²h, where r is the radius and h is the height.

Insert the values into the equation:

1/3\pi(5)²(11) ≈ 287.979327 (use a calculator for this part)

Divide 287.979327 by \pi and convert the decimal to a fraction:

91.66666666666666666666666666666666666666... = 91 2/3

The volume of the figure is 91 2/3\pi cubic units or units³.
