A physical education teacher plans to divide the seventh graders at Wilson middle school into teams of equal size for a year-end

serg [7]

Answer:

• It is possible to divide the seventh graders into teams of equal sizes.

• 13 students should be on each team.

Explanation:

The seventh grade of Wilson consists of three classes; one with 28 students, one with 29, and one with 34. Therefore, the total number of students in seventh grade is:

$\text{Total}=28+29+34=91$

He wants each team to have between 4 and 8 students.

$\begin{gathered} \frac{91}{4}\approx22.75 \\ \frac{91}{5}\approx18.2 \\ \frac{91}{6}\approx15.2 \\ \frac{91}{7}\approx13 \\ \frac{91}{8}\approx11.4 \end{gathered}$

Therefore:

• It is possible to divide the seventh graders into teams of equal sizes.

• 13 students should be on each team.

Suppose that past history shows that 60% of college students prefer brand c cola. a sample of 5 students is to be selected. base

creativ13 [48]

The probability is 0.337.

The probability that more than 3 prefer brand c is the same as finding the probability that 4 or 5 prefer brand c. Using a binomial distribution,

$_5C_4(0.6)^4(0.4)^{5-4}+_5C_5(0.6)^5(0.4)^{5-5}
\\
\\=\frac{5!}{4!1!}(0.6)^4(0.4)^1+\frac{5!}{5!0!}(0.6)^5(0.4)^0
\\
\\=5(0.6)^4(0.4)+1(0.6)^5(1)=0.33696\approx0.337$
