A binomial probability density function should be used to represent the probability

<h3>How to determine the type of probability density?</h3>

The given parameters are:

  • Proportion that plays sport, p = 32%
  • Number of students selected, p = 50
  • The probability, P = (x ≤ 15)

The proportion that plays sport indicates that

68% of the students do not play sport

So, we have two events, which are

  • Play sport
  • Do not play sport

When there are two possible events, then the binomial probability density function should be used

Find the area of the sector
sergij07 [2.7K]

Answer:

\boxed {\boxed {\sf a \approx 190.9 \ yd^2}}

Step-by-step explanation:

There are 2 formulas for the area of a sector, but since we are given the central angle in degrees (not radians), we will use this formula:

a= \frac {\theta}{360} \times \pi r^2

Where θ is the central angle and r is the radius.

For this circle, the radius is 9 yards and the central angle is 270 degrees. We can substitute these values into the formula.

a= \frac {270}{360} \times \pi \times (9 \ yd )^2

Solve the fraction.

a=0.75 \times \pi \times (9 \ yd)^2

Solve the exponent.

  • (9 yd)²= 9 yd* 9 yd=81 yd²

a= 0.75 \times \pi \times 81 \ yd^2

Multiply all three numbers together.

a= 190.851753706 \ yd^2

The question asks us to round to the nearest tenth.

  • 190.8<u>5</u>1753706

The 5 in the hundredth place tells us to round the 8 up to a 9.

a \approx 190.9 \ yd^2

The area of the sector is approximately <u>190.9 square yards. </u>

Juan wants to find the mode of the data set below.

Answer:

A line plot shows all the numbers lined up and will easily show what the mode, or most occurring number is. A stem and leaf plot shows this, but is less clear and is more used for what numbers are.
