Is 1000 a term in the sequence 50,65,80,95

Alex Ar [27]

Yes it is

it’s the 41st term

EXPLANATION:

the nth term would be 15n+35
because the terms go up by 15 and you add 35 to get to the term.

1. 2. 3. 4.
50. 65. 80. 95

1000- 35= 965

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

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