Answer:

Step-by-step explanation:

Given

-x (y + z)

If y = -3

x = 4 and

z = -5

Substitute the respective values into the expression

-(4) (-3 + -5)

Positive negative when combined gives negative

-4 ( -3 - 5)

Simplify the bracket

-4 (-8)

Step-by-step explanation:

we know that

If the lines m and n are parallel

then

$130\° = (8x+50)\°$ ----> by corresponding angles

Olin [163]

Answer:

$P(16.5$

And using the normal standard table or excel we find the probability:

$P(-1.768< Z< 1.768) = P(Z$

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Solution to the problem

Let X the random variable that represent the avergae number of weeks an individual is unemployed of a population, and for this case we know the distribution for X is given by:

$X \sim N(17.5,4)$
