Answer:
Quotient = -x² -3x +2.
Step-by-step explanation:
Given : quantity of 3 times x to the 3rd power plus 9 times x to the 2nd power minus 6 times x all over negative 3 times x.
To find : Find the quotient.
Solution : We have given that statement
3 times x to the 3rd power = 3x³.
9 times x to the 2nd power =9x²
6 times x = 6x
3x³ +9x²-6x over -3x.
On dividing 3x³ +9x²-6x by -3x
.
On cancel out the like numertor and denominator.
Quotient = -x² -3x +2
Therefore, Quotient = -x² -3x +2.

Answer:
The least number of tennis balls needed for the sample is 1849.
Step-by-step explanation:
The (1 - <em>α</em>) % confidence interval for population proportion is:
The margin of error for this interval is:
Assume that the proportion of all defective tennis balls is <em>p</em> = 0.50.
The information provided is:
MOE = 0.03
Confidence level = 99%
<em>α</em> = 1%
Compute the critical value of <em>z</em> for <em>α</em> = 1% as follows:
*Use a <em>z</em>-table.
Compute the sample size required as follows:
Thus, the least number of tennis balls needed for the sample is 1849.
