Answer: I THINK ITS HEATHER
Step-by-step explanation:
Answer:
2.28% probability that a person selected at random will have an IQ of 110 or greater
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 greater?
This is 1 subtracted by the pvalue of Z when X = 110. So



has a pvalue of 0.9772
1 - 0.9772 = 0.0228
2.28% probability that a person selected at random will have an IQ of 110 or greater
Answer:
p1 = 70 deer
p2 = 98 deer
Step-by-step explanation:
We use the population growth expression:

which in our case renders:

Therefore, after 1 year the population would be:

giving a total of 70 deer
and after two years, it would be:

Answer:
(x-9)^2
Step-by-step explanation:
Answer: w - 7
Step-by-step explanation:
The expression is simply less 7 less than w, or w - 7.
