Increasing the sample size by a factor of 4 or multiplying
it by 4 is equal to increasing the standard error by 1/2. Therefore, the
interval will be half as varied. This also works almost for population
averages as lengthy as the multiplier from the t-curve doesn't modify much when
increasing the sample size.
Answer: B
Explanation: 9 is the only odd number meaning it’s contradicting the claim that all perfect squares are even since 9 isn’t even. a 3x3 square would be 9 but its also perfect explaining how not all perfect squares are even.
Not sure what y is but x is 40.6666

The <em>correct answer</em> is:
$19,153.26.
Explanation:
She will receive 42% of her average annual salary. This salary was $45,603.
To find 42% of a number, we first convert the percent to a decimal: 42% = 42/100 = 0.42.
Next we multiply this by the number we're taking the percent of:
0.42(45603) = 19153.26.
