Answer: 30 percent of people who do not brush theit teeth every night.

Step-by-step explanation:

Given : 7 out of 10 people brush their teeth every night.

That means 3 out of 10 people do not brush their teeth every night. (7-10=3)

Now, the percent of people who do not brush their teeth every night = \dfrac{\text{Number of people do not brush their teeth}}{\text{Total people}}\times100\%

=\dfrac{3}{10}\times100\%\\\\=30\%

Hence, 30 percent of people who do not brush theit teeth every night.

A physics exam consists of 9 multiple-choice questions and 6 open-ended problems in which all work must be shown. If an examinee
katrin [286]

Answer: A) 1260

Step-by-step explanation:

We know that the number of combinations of n things taking r at a time is given by :-

^nC_r=\dfrac{n!}{(n-r)!r!}

Given : Total multiple-choice questions  = 9

Total open-ended problems=6

If an examine must answer 6 of the multiple-choice questions and 4 of the open-ended problems ,

No. of ways to answer 6 multiple-choice questions

= ^9C_6=\dfrac{9!}{6!(9-6)!}=\dfrac{9\times8\times7\times6!}{6!3!}=84

No. of ways to answer 4 open-ended problems

= ^6C_4=\dfrac{6!}{4!(6-4)!}=\dfrac{6\times5\times4!}{4!2!}=15

Then by using the Fundamental principal of counting the number of ways can the questions and problems be chosen = No. of ways to answer 6 multiple-choice questions x No. of ways to answer 4 open-ended problems

= 84\times15=1260

Hence, the correct answer is option A) 1260
