Find the probability of having 2, 3, or 4

Mathematics
1 answer:
denis-greek [22]2 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%

Find the solution set of this system:
bezimeni [28]

Answer:

(−4, 12), (1, −3)

Step-by-step explanation:

y = −3x

x^2 −4 = y

so

x^2 −4 = −3x

x^2 + 3x - 4 = 0

(x + 4)(x - 1) = 0

x + 4 = 0; x = -4

x - 1 = 0; x = 1

when x = 1, y = -3(1) = -3

when x = -4, y = -3(-4) = 12

Answer

(-4 , 12), (1 , -3)

Find the slope of the line through
Dafna11 [192]
When finding the slope between two points, we simply take (y2-y1) / (x2-x1)
For this, we can substitute the following to get this :
y2-y1 and x2-x1
1 - 4 and 7 - 1
-3 and 6
-3 / 6 gets you -1/2

Therefore the answer is :
The slope of the line is -1/2

djyliett [7]

Answer:

<em>5.5</em>

Step-by-step explanation:

Given the set of data

5, 4, 2, 1, 1, 2, 10, 2, 3, 5.

The average of the least and the greatest value is known as the midrange

The formula for calculating the midrange is expressed as shown:

Midrange = (Greatest value + Least value)/2

Given

Greatest value = 10

Least value = 1

Midrange = 10+1/2

Midrange = 11/2

Midrange = 5.5

<em>Hence the midrange of the data is 5.5</em>

F(x)=2x-3 g(x)=x^2+1 find g(2)
Hitman42 [59]

Answer:

g(2)=5

Step-by-step explanation:

since g(x) is equal to x^2+1, you just plug in the value of 2 for x, to get 2^2+1, and 2 to the power of 2 (also known as 2 squared) is equal to 4, which makes your equation 4+1, which equals 5.
