Z-scores (left tail) of a given variable X are calculated by
Z(x)=(x-mean)/standard deviation.
For Mary:
Zm(124)=(124-110)/8=14/8=1.75
For Carrie:
Zc(289)=(289-250)/20=39/20=1.95
therefore
Zc>Zm
Answer: k ≥ -1
Step-by-step explanation:
7k - 2 ≥ -9
add two to both sides
7k ≥ -7
k ≥ -1
As you need to translate to the left this is an horizontal translation so you have to replace f(x) by f(x-h) and when h is less than 0 the graph shifts left, it mean h is negative. So for this problem g(x)= Ι2(x--5)Ι then g(x) = Ι2(x+5)Ι
Using order of operations, I simplified this down to -24+22a.
I hope this helps, and let me know if you need more explanation!
