50 55 66 26 84
59 64 88 23 27
70 63 42 37 29
The answer is
Step-by-step explanation:
As the data is not given in the question i'm guessing the data from the question i solved before
28 78 74 89 72
50 55 66 26 84
59 64 88 23 27
70 63 42 37 29
as taking the above data,
As we know for finding the width of class:
≈
Note : By using the above given formula you can calculate the width of any data just by taking the maximum and minimum values of data and the number of classes the data is divided into.
Answer:
Opt. D.
Step-by-step explanation:
To solve this problem we need to focus our attention in the abs(x-1) function,
If x>1, then abs|x-1|= x-1, if x<1 then abs|x-1|= 1-x. And in the two intervals, the function opens upwards.
But our function has -3 multiplying abs|x-1|, This means that our function opens downward.
The vertex point can be found when x=1, since abs(x-1)=0. this gives f(1)=12
