Answer:
m=-5
Step-by-step explanation:
You first do distributive property:
(-m*-1)+(-1*-7)+(-3*4m)+(-3*-3)=71
that simplifies to:
16-11m=71
Next subtract 16 on both sides and you get:
-11m=55
Then divide by -11,
m=-5

Answer:
-72
Step-by-step explanation:
If they descend, this can be represented by a negative number.
Since they descended 72 feet, the worker's change in position can be represented by -72.
So, the answer is -72
In a normal distribution, the z value for an x value that is to the right of the mean will always be positive while on the other hand if the z value for an x value that is to the left of the mean it will always be negative. It is because left side is always negative and right side is always positive.
