Answer:
6
Step-by-step explanation:
your answer is 6 because she did 12 in 1hr and the other 12 in 3hr so you take 3=1+4 and divide 24 by 4 which is 6
Keri= 13/32x100/1=40.6%
Mathew=15/43x100/1=34.8%
Liam=12/28=3/7x100/1=42.86%
Highest=Liam
Lowest=Matthew
The statement is false, because -2 is larger than -3.
<h3>Is the statement true?</h3>
We know that -3 is a lower bound for the real zeros of f(x).
So, if we define k as the smallest real zero of f(x), we have:
-3 < k.
Then we can take, for example, k = -2.5
That is an allowed value for the real zero.
In that case, -2 is not a lower bound, because is false that:
-2 < k = -2.5
Then if -3 is a lower bound for the real zeros of f(x), we can't assume that -2 is also a lower bound (because -2 is larger than -3).
