Answer: 27.4 hours
Step-by-step explanation:
According to the given statement "A survey of 45 teens found that they spent an average of 25.6 hours per week in front of a screen (television, computer, tablet, phone, etc.)."
Since the word average is synonym of word mean.
Therefore, the sample mean must have the nearest value to the given average.
From the given options 27.4 is the nearest value to the average of 258.6.
Hence, the population mean = 27.4 hours.
Answer:
1/6
Step-by-step explanation:
Divide by 3
9/54 = 3 / 18
You can again divide by 3 for the answer
1/6
Acceleration is the change in velocity over time. There's are formula's for such problems which are called kinematics equations. Look em up. One of them doesn't have t (time) in them you would normally use that one to solve this problem. 16/2/20=a=0.4m/s^2
I did it for you but please look it up, understand and memorize it ;)
Answer: choice A) 7017
==========================================================
Work Shown:
The first term is a_1 = 24 and we go up by 7 each time.
The common difference is d = 7
The nth term formula we'll use is
a_n = a_1 + (n-1)*d
a_n = 24 + (n-1)*7
----------
The 1000th term corresponds to n = 1000
Replace every n with 1000
Then use the order of operations (PEMDAS) to simplify
a_n = 24 + (n-1)*7
a_1000 = 24 + (1000-1)*7
a_1000 = 24 + (999)*7
a_1000 = 24 + 6993
a_1000 = 7017
