Answer:

n (aub)= n (a)+ n(b)

n (anb) = n (a)-n (b)

only a= n(a)+n(b) -(aub)

n only b= n (a)+n (b)-n (anb)

now solve your self because this formula help to solve

The perimeter of the polygon above is?

jenyasd209 [6]

Perimeter = the addition of all of the side lengths of the polygon.

The side lengths are 9cm, 6cm, 10cm, 5cm, 4cm, and 4cm.

So the perimeter is the following...

Perimeter = 9 + 6 + 10 + 5 + 4 + 4 = 38cm total

If IQ scores are normally distributed with a mean of 100 and a standard deviation of 5, what is the probability that a person se

notsponge [240]

Answer:

2.28% probability that a person selected at random will have an IQ of 110 or higher

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 100, \sigma = 5$
