Answer:
7/12
Step-by-step explanation:
The nth term Tₙ = n(n-4) /n+3.
The 1st term T₁ = 1(1 - 4)/(1 + 3) = -3/4
The 6th term T₆ = 6(6 - 4)/(6 + 3) = 6(2)/9 = 2(2)/3 = 4/3
So, the sum of the 1st and 6th terms is T₁ + T₆ = -3/4 + 4/3
= (-9 + 16)/12
= 7/12
The sampling technique used is Simple Random Sampling option fourth would be the best choice.
<h3>What is simple random sampling?</h3>
Simple random sampling is a sampling strategy in which every item in the population has an equal probability of being chosen for the sample.
Simple random sampling selects a sample of objects at random from a population, with each item having an equal chance of being chosen.
Simple random sampling selects items for its sample from a table of random numbers or an electronic random number generator.
Thus, the sampling technique used is Simple Random Sampling option fourth would be the best choice.

Answer:
x = -5/2
Step-by-step explanation:
3 ^ ( 4x-5) = (1/27) ^( 2x+10)
Rewriting 1/27 as 3^-3
3 ^ ( 4x-5) = (3^-3) ^( 2x+10)
We know that a^b^x = a^(b*c)
3 ^ ( 4x-5) = (3) ^(-3*( 2x+10))
3 ^ ( 4x-5) = (3) ^( -6x-30)
The bases are the same so the exponents are the same
4x-5 = -6x-30
Add 6x to each side
10x -5 = -30
Add 5 to each side
10x -5+5 = -30+5
10x = -25
Divide each side by 10
10x/10 = -25/10
x = -5/2
Answer:
Confused as well
Step-by-step explanation:
If there are hypothetically 10 hours a day with 100 minutes an hour and 100 seconds per minute
at 6 pm there would be 18 hours gone in the day
18 normal hours are equal to 18*60*60 = 64800 seconds
(64800 seconds) / 10000 ( for hours)
6:48 would be the replacement time
but this answer is wrong bc it's not an option
