What is the leading coefficient that would be used for scientific notation of this number? (12,500,000,000)
SIZIF [17.4K]

Answer:

1.25 would be the leading coefficient

Step-by-step explanation:

Leading coefficients in scientific notation have to be more than 1, and less than 10. Therefore, 12.5 or 0.125 would not be correct answers as they do not fit the criteria. Only 1.25 would work as the leading coefficient.

Twelve jurors are randomly selected from a population of 4 million residents. Of these 4 million​ residents, it is known that 46
vekshin1

Answer:  a) 0.17, b) 0.0363

Step-by-step explanation:

Since we have given that

Number of jurors selected = 12

Number of minorities of jurors = 2

​(a) What proportion of the jury described is from a minority​ race? ​

\dfrac{2}{12}=\dfrac{1}{6}=0.166666\approx0.17

(b) If 12 jurors are randomly selected from a population where 46​% are​ minorities, what is the probability that 2 or fewer jurors will be​ minorities?

Let X be the number of jurors who are minorities.

Probability of getting minorities = 0.46

Probability of getting no minorities = 1-0.46 =0.54

P(X\leq 2)=^{12}C_0(0.54)^{12}+^{12}C_1(0.46)(0.54)^{11}+^{12}C_2(0.46)^2(0.54)^{10}\\\\P(X\leq 2)=0.0363

(c) What might the lawyer of a defendant from this minority race​ argue?

Since the number of minorities juror are high among the population.

Hence, a) 0.17, b) 0.0363
