Answer:

Step-by-step explanation:

Nicole usually scores between 89% and 100% on her math quizzes.

On the quizzes she takes right after a track meet, she has about an 11% decrease in her score, so she will earn 100% - 11% = 89% of her usual score.

1. 89% of 89% is

$0.89\cdot 89\%=79.21\%\approx 79\%$

2. 89% of 100% is

$0.89\cdot 100\%=89\%$

So, if Nicole had a track meet the day before a quiz, her score would be between 79% and 89%.

Answer:

$= {x}^{ - 11} {y}^{ - 11} {z}^{ - 10}$

Step-by-step explanation:

$= \frac{ {x}^{ - 9} {y}^{ - 5} {z}^{ - 7} }{ {x}^{2} {y}^{6} {z}^{3} } \\ = {x}^{ - 9 - 2} {y}^{ - 5 - 6} {z}^{ - 7 - 3} \\ = {x}^{ - 11} {y}^{ - 11} {z}^{ - 10}$

In a certain college, 33% of the physics majors belong to ethnic minorities. Of 8 students are selected at random from the physi

Answer: 0.0187

Step-by-step explanation:

The binomial distribution formula for probability :-

$P(x)=^nC_xp^x(1-p)^{n-x}$ , where P(x) is the probability of getting success in x trials , n is the total number of trials and p is the probability of getting success in each trial.

Given : The probability that the physics majors belong to ethnic minorities =0.33

Number of students selected : n= 8

Now, the probability that more than 5 belong to an ethnic minority :-

$P(x>5)=P(6)+P(7)+P(8)\\\\=^8C_6(0.33)^6(0.67)^{2}+^8C_7(0.33)^7(0.67)^{1}+^8C_8(0.33)^8(0.67)^{0}\\\\=(\dfrac{8!}{6!2!})(0.33)^6(0.67)^{2}+(8)(0.33)^7(0.67)^{1}+(0.33)^8(0.67)^{0}\\\\=0.0186577086013\approx0.0187$
