Step-by-step explanation:
Mean = Average : Sum of the data ÷ Number of data
So find the average number of lates per student
4 = Lates
30 (sum of frequencies) = Frequencies
So 4 ÷ 30 = 7.5
Therefore the answer is 7.5..
Hence, Answer is = - 2(x - 4)
2000 divided by 0.08% and that's how many years
Answer:
(B) y=2x^2
Step-by-step explanation:
(1/2) and (1/4) make the graph wider
2 makes it narrower
<em>f(d)=86,400·d</em>
if you set 1 day (d=1) you get f(1)=86,400 sec
if you set 1 day (d=2) you get f(2)=172,800 sec
...etc.
