Answer— 2
Explanation- simple math
The original median is the number in the middle of 60, 70, 80, 80, 100, so the median is 80.
the new median is the number in the middle of 0, 60,70,80,80,100, the median is between 70 and 80, so it is 75
the original mean is (60+70+80+80+100)/5=78
the new mean is (0+60+70+80+80+100)/6=65
so the mean decreases more than the median. C is the answer. <span />
Answer: our function is:
f(x) = A*sin(2*pi*270s*x)
Step-by-step explanation:
We have that the frequency of a given engine is 270 hz, it starts at 0, so we may represent this with a sin function (because sin(0) = 0)
Then we could use the function
f(x) = A*sin(c*x)
A is the maximum intensity of the hum, and c depends on te frequency, we know that the period of a sin function is 2pi, then:
f = 270/s
T = 1/270s
c*1/270s = 2pi
c = 2*pi*270s
Then our function is:
f(x) = A*sin(2*pi*270s*x)
Answer:
The stack will be 4.54 feet tall
Step-by-step explanation:
Firstly, we want to write the decimal expression for 2 3/11
That will be 2 + 0.2727
To 2 decimal place, that will be 2.27
Staking the two boxes means we are placing one on the other
So the height of the stack will be 2.27 + 2.27 = 4.54 feet
Answer:
See below
Step-by-step explanation:
0.82=82/100=82%
22%=22/100=0.22
3/4=0.75=75/100=75%
0.8=0.80=80/100=80%
Hope this helps!
