X-4/3 <= 5
Multiply both sides by 3:
X-4 <= 15
Add 4 to both sides:
X <= 19
The answer is the third one.
X = 8/(-1/3) therefore the answer is -24
The "mean" is just the normal arithmetic average that you are most likely already familiar with.
mean=(sum of elements)/(number of elements)
In this case:
mean=(2+28+2+20+22)/5
mean=74/5
mean=14.8
So the mean or average age of the trees is 14.8 years.
Answer:
z = -3
Step-by-step explanation:
42 = -7 ( z-3)
42 = -7z + 21
21 = -7z
z = -3
