Answer:

√50 is an irrational number

Step-by-step explanation:

$\sqrt{50} = 7.071067......$

Here,

√50 is an irrational number

Because-

we can't write the number (7.071067....) as a fraction .
The number has endless non-repeating digits to the right of the decimal point.

Simplify the expression 5(n^2+n)-3n(2n^2+4n-2)

slega [8]

first, lets distribute the equation. 5(n^2+n)-3n(2n^2+4n-2) would become

5n^2 +5n -6n^3 -12n^2 +6n

Now we add the like terms.

-6n^3 - 7n^2 +11n

The life of light bulbs is distributed normally. The standard deviation of the lifetime is 15 hours and the mean lifetime of a b

Anastaziya [24]

Answer:

0.8413 = 84.13% probability of a bulb lasting for at most 605 hours.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

The standard deviation of the lifetime is 15 hours and the mean lifetime of a bulb is 590 hours.

This means that $\sigma = 15, \mu = 590$
