In​ 2005, out of every 50 employees at a company were women. If there are total company​ employees, estimate the number of women
myrzilka [38]

Answer:

9248

Step-by-step explanation:

let x be the number of women out of 41285 total company employees then we have the following proportion

11.2 : 50 = x : 41285

x = (41285 * 11.2)/50

x = 9247.84

the number of women is 9247.84 or if we round it since we can not have 0.84 of a woman employee, is it 9248.

A singing contest eliminates contestants after each round. The number of contestants that go into round n is equal to the number
dimaraw [331]

Answer:

9

Step-by-step explanation:

Since we know the number of contestants in Round 2, we could go step by step and calculate the number of remaining contestants in Round 3, then Round 4 and finally Round 5.

However, we can do it without calculating. So in Round 3, there will be:

R3 = R2^((n-1)/n), where n is number of the round

R3 = R2^(2/3)

For Round 4, the number will be:

R4 = (R2^(2/3))^(3/4)

And Round 5 will be:

R5 = ((R2^(2/3))^(3/4))^(4/5)

Threes and fives in exponents will cancel out and we'll remain only with:

R5 = R2^(2/5)

R5 = 249^(2/5)

R5 = 9.08

Rounded to the nearest integer, the number of contestants in Round 5 is 9.

A line is an undefined term because it
Bond [772]
<span>It is undefined because it is one of the building blocks of geometry.
In order to define a term, we must have a definition of <u>all of the words</u> used to describe it. As this progresses, we would have a never-ending list of words to define; at some point, we must accept a few basic building blocks as being undefined.</span>
