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 and standard deviation
, the zscore of a measure X is given by:
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:
What is the probability that a person selected at random will have an IQ of 110 or higher?
This is 1 subtracted by the pvalue of Z when X = 110. So
has a pvalue of 0.0228
2.28% probability that a person selected at random will have an IQ of 110 or higher
is the expression that demonstrates the distributive property
<em><u>Solution:</u></em>
Given that,
At a ski resort, of the 300 skiers are beginners
of the 260 snowboarders are beginners
The resort staff used the distributive property to make the calculation of the total number of beginners on the ski slopes
Beginners in skiers = of the 300
Beginners in snowboarders = of the 260
Total number of beginners = Beginners in skiers + Beginners in snowboarders
We have to use distributive property
The distributive property of multiplication states that when a number is multiplied by the sum of two numbers, the first number can be distributed to both of those numbers and multiplied by each of them separately, then adding the two products together for the same result as multiplying the first number by the sum
<h3>a(b + c) = ab + bc</h3><em><u>Therefore, our expression is:</u></em>
We have to take as common term to get distributive property
Thus distributive property is applied
