A researcher wishes to conduct a study of the color preferences of new car buyers. suppose that 50% of this population prefers t
djyliett [7]

To solve this question, use the Binomial probability formula.

The formula is given by

^nC_xp^x(1-p)^{n-x}

Where:

n = the number of trials

x = the sample we aim to try

p = the probability of success

In this question:

n = 16

x = 9

p = 0.5

Substituting in the equation:

\begin{gathered} ^nC_xp^x(1-p)^{n-x} \\ ^{16}C_9*0.5^9(1-0.5)^{16-9} \\  \end{gathered}

And the combination formula:

^nC_x=\frac{n!}{(n-x)!*x!}

Then:

\begin{gathered} \frac{16!}{(16-9)!*9!}*0.5^9(1-0.5)^{16-9} \\ \frac{16!}{7!*9!}*0.5^9*0.5^7 \\ 11440*0.00195*0.0078 \\ =0.1746 \end{gathered}

Answer: The probability is 0.1746.

Radda [10]

Answer:

12

Step-by-step explanation:

Regular work week is 40 hours; at $16.50 per hour, that comes to $660.

Subtracting $660 from the toal $948.75 yields $288.75, which represents her pay at the overtime rate of (1.5)($16.50/hr), or $24.75/hour

Dividing $288.75 by this overtime rate of $24.75/hr yields 11.666 ...

We conclude that she worked approximately 12 hours overtime to end up

with $948.75 total pay.
