After flying between two black holes, our engines have been a bit janky. The probability of one of any of our 8 power couplings

otez555 [7]

Answer:

Step-by-step explanation:

We would apply the formula for binomial distribution. It is expressed as

P(x = r) = nCr × q^(n - r) × p^r

Where

p represents probability of success

q represents probability of failure.

n represents number of sample.

From the information given,

p = 10% = 10/100 = 0.1

q = 1 - q = 1 - 0.1 = 0.9

n = 8

1)The probability that none fails is

P(x = 0) = 8C0 × 0.9^(8 - 0) × 0.1^0

P(x = 0) = 0.43

2) The probability that one fails is

P(x = 1) = 8C1 × 0.9^(8 - 1) × 0.1^1

P(x = 1) = 0.38

3) The probability that four fails is

P(x = 4) = 8C4 × 0.9^(8 - 4) × 0.1^4

P(x = 4) = 0.0046

3) The probability that six fails is

P(x = 6) = 8C6 × 0.9^(8 - 6) × 0.1^6

P(x = 6) = 0.00002268

4) The probability that eight fails is

P(x = 8) = 8C8 × 0.1^(8 - 8) × 0.1^8

P(x = 8) = 0.00000001

Can anyone help me with part b? I will mark you as brainliest!

Kruka [31]

Answer:

There are 75 total cubes in the box.

Step-by-step explanation:

If 0.4 is 30, then divide 30 by 4 and then multiply that by 3, because that would be the answer for red or yellow, then just multiply 22.5 x 2 to find both red and yellow. Finally, add 30 and 45 for your answer.

A function f is differentiable for all values of x in [0,6], and the graph with equation y=f(x) has a local minimum point at (2,

MrRa [10]

Step-by-step explanation:

The slope of tangent line at a max or a minimum is 0,.

So using point slope formula.

$y - 4 = 0(x - 2)$

$y = 4$

Is the equation of a tangent line. This means we have a horizontal line at y= 4. Horizontal lines have a slope of 0.

Find all the zeroes of the polynomial function f(x)=x^3-5x^2+6x-30 using synthetic division.

WITCHER [35]

Write the coeeficientes of the polynomial in order:

| 1   - 5   6   - 30
|
|
|
------------------------

After some trials you probe with 5

   | 1   - 5    6     - 30
   |
   |
5 |        5      0       30
-----------------------------
   1    0      6        0 <---- residue

Given that the residue is 0, 5 is a root.

The quotient is x^2 + 6 = 0, which does not have a real root.

Therefore, 5 is the only root. You can prove it by solving the polynomial x^2 + 6 = 0.
