Answer:

Step-by-step explanation:

if 5^{x-3} =3^{2x+1} \\(x-3)log 5=(2x+1)log 3\\x log 5-3 log 5=2 x log 3+log 3\\x(log 5-2 log 3)=log 3 +3 log 5\\x=\frac{log 3+3 log 5}{log 5-2 log 3} \\\\x \approx -10.08

weeeeeb [17]

Answer:

Probability that they are the youngest is 0.000549

Step-by-step explanation:

Given

Number of students = 16

Selected students = 4

Let n = number of students

n = 16

Let r = selections

r = 4

We're interested in selecting 4 students out of 16; the keyword, selection means we're dealing with combination because order is not important.

So,

Solving for nCr

nCr = n!/((n-r)!r!)

16C4 = 16!/((16-4)!4!)

16C4 = 16!/(12!4!)

16C4 = 16 * 15 * 14 * 13 * 12!/(12!4!)

16C4 = 16 * 15 * 14 * 13 / 4 * 3 * 2 * 1

16C4 = 1820 ways

There are 1820 ways of selecting 4 students from a total of 1820.

Only one of these ways can the four of them be the youngest.

So, probability = 1/1820

Probability = 0.0005494506

Probability that they are the youngest is 0.000549 (approximately)
