Answer:
0.324
Step-by-step explanation:
Given that :
Success rate = 30%
p = 30% = 0.3
q = 1 - p = 1 - 0.3 = 0.7
Number of trials, n = 6
Probability of having exactly 2 successes ; x = 2
P(x = 2)
Usibgbtge binomial probability relation :
P(x = x) = nCx * p^x * q^(n-x)
P(x = 2) = 6C2 * 0.3^2 * 0.7^4
P(x = 2) = 15 * 0.3^2 * 0.7^4
P(x = 2). = 0.324135
P(x = 2) = 0.324
4+1/ 20
It would be in a fraction like form.
Okay wait what how i do this mark me brainless 0
Answer:
Step-by-step explanation:
The triangle is recognizable as a 30°-60°-90° right triangle, which has side length ratios ...
1 : √3 : 2
Side x is thus twice the length of short side 4, so x = 8.
Side y is √3 times the length of short side x-6 = 2, so y = 2√3.
_____
If you don't happen to recognize the triangle dimensions, you can find x and y using the Pythagorean theorem.
x = √(4² +(4√3)²) = √64 = 8
y = √(4² -2²) = √12 = 2√3
Answer:
- There is no power of 2 that is equal to 0.
- Its inverse does not have any x-intercepts.
Step-by-step explanation:
Given the function
This function can be written as:
As the rule tells s that
so
As we know that the value of x=0 at y-intercept.
For any value of 
, this statement is false as there is no power of 2 that is equal to 0.
Also
Lets interchange x and y in the equation to find the inverse of the function.
So, it doesn't have any x-intercepts as for any value of x, the value of can not be zero for this function.
Therefore, Its inverse does not have any x-intercepts.
