Answer:
b) 1.34
Step-by-step explanation:
The z score is used to determine the number of standard deviations by which the raw score is above or below the mean. If the z score is positive then the z score is above the mean while for a negative z score implies that it is below the mean. The z score is given by:
For the largest 9%, the score is 100% - 9% = 91% = 0.91
From the normal distribution table, the z score that corresponds to 0.91 is 1.34
A function assigns values. The inequality one-half x minus 10 greater-than-or-equal-to 0 should be satisfied.
<h3>What is a Function?</h3>A function assigns the value of each element of one set to the other specific element of another set.
The domain of a function is a set of values for which the equation is satisfied. Since the function has under root values, the value which is under the root should be non-negative so that it does not give a complex number, therefore,
The inequality satisfied to find the domain of the function f(x).
Also, we can write that 0.5x²-10≥0 for the value to be positive.
Hence, the inequality one-half x minus 10 greater-than-or-equal-to 0 should be satisfied.
