Answer:
The greatest common factor of and
is 3rd answer
Step-by-step explanation:
The greatest common factor of some numbers is the highest common factor of these numbers
Ex: The highest common factor of 8 and 12 is 4 because the factors of 8 are 1, 2, 4, 8 and the factors of 12 are 1, 2, 3, 4, 6, 12, so the common factors of them are 1, 2, 4 and the highest one is 4
The greatest common factor of some terms of the same variable is the smallest exponent
Ex: The greatest common factor of x² and x³ is x²
∵ The terms are and
∵ The smallest exponent is 5
∴ The greatest common factor of and
is

and the Answer for Second equation is option D.
Using the normal distribution, it is found that 1851 people would have an IQ less than 115.
<h3>Normal Probability Distribution</h3>The z-score of a measure X of a normally distributed variable with mean and standard deviation
is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The mean and the standard deviation are given, respectively, by:
The proportion of IQ scores less than 115 is the <u>p-value of Z when X = 115</u>, hence:
Z = 1
Z = 1 has a p-value of 0.8413.
Out of 2200 people:
0.8413 x 2200 = 1851.
