Consider the following binomial experiment:

Mathematics
1 answer:
Sedbober [7]3 years ago
4 0

Answer:

0.624

Step-by-step explanation:

Given that:

Number of copiers with the company = 4

It is a binomial experiment.

Probability that on a given day, one copier will break down = \frac{23}{50}

p = \frac{23}{50} = 0.46

q = 1-p = 1-\frac{23}{50}= \frac{27}{50} = 0.54

<em>Formula for Binomial probability: </em>

P(x=r) = _{n}C_{r}p^rq^{n-r}

We have to find P(x >= 2)

P(x >= 2) = P(X=2)+P(X=3)+P(X=4)

P(x=2) = _{4}C_{2}0.46^2\times 0.54^{2} = 0.37\\P(x=3) = _{4}C_{3}0.46^3\times 0.54 = 0.21\\P(x=4) = _{4}C_{4}0.46^4\times 0.54^{0} = 0.044

P(x >= 2) = 0.37 + 0.21 + 0.044 = \bold{0.624}

The sequence of transformations R0,90 r x-axis is applied to XYZ to produce X’’ Y’’ Z’’. If the coordinates of Y’’ are (3,0),wha
Fofino [41]

Answer:

Y = (0, 3)

Step-by-step explanation:

Notice that the first the transformation is a rotation of 90 degrees around the origin, and then a reflection around the x axis.

If a reflection around the x axis resulted in (3, 0)  that means the point was already on the x axis.

Then in order for a rotation in 90 degrees to take the point Y to (3, 0), Y must have been on the y-axis as (0, 3)

What is the best path to convert 100 liters to pints?
Pachacha [2.7K]
1 liter is equal to 2.11338 pints
 
To convert 100 liters to pints you would do 100 * 2.11338, or move the decimal place two places to the right, so you have 211.338 pints.
