Answer:

n=-4

Step-by-step explanation:

Note: It is not given what to find so that i am finding the value of n

Given :

$5^{n} =\frac{1}{625} \\5^n=\frac{1}{5^4} \\5^n=5^{-4} \\So,\\n=-4$

Therefore,

n=-4

Answer:

n = - 4

Step-by-step explanation:

note that 625 = $5^{4}$ , then

$5^{n}$ = $\frac{1}{5^{4} }$ = $5^{-4}$

Since the bases on both sides are equal, both 5 then equate the exponents

n = - 4

What us the intercept form of (1,2) and (4,-4)

lutik1710 [3]

first you need to find the slope (m) using y2-y1/x2-x1.

-4-2/4-1= -6/3=-2

m=-2

then plug into the intercept form formula: y-y1=m(x-x1)

y-2=-2(x-1)

What is the mode median and mean

stellarik [79]

The mode is 17 because it occurs most often.

There are 23 data points, so the 12th one is the median (middle). The median is 15.

The mean is 15.435 because it is the average. Add up all the ages, then divide by the number of people.

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

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
