Answer:
-3/4 + 1/2 = -1/4
Step-by-step explanation:
Think of it this way; We know that 1/2= 2/4
so the equation could be modeled like this
-3/4+2/4= ?

Answer:
B. The company hires 10 employees every year.
Step-by-step explanation:
One way to look at this is to look at the units on the number 10. Working strictly with units, we get ...
f(x) = 10x . . . . . . f(x) is employees, x is years
employees = 10·years
Dividing by years, we find the meaning of "10":
employees/year = 10
The division symbol (/) is read as "per", so this means the number 10 in the equation is the number of employees per year that are hired.
10 employees are hired every year.
Answer:
Step-by-step explanation:
When you add the left side of the equation, you get 33.2 because 70-30 is 40, 40+2 is 42, 42-9 is 33, 33+0.3 is 33.03, 33.3-0.1 is 33.2.
When you add the right side of the equation, you get 33.2, because they are the same problem but on side has brackets.
Hope this helps you.
Answer: The shortest living man at that time had the height that was more extreme.
Step-by-step explanation:
We will z scores to solve this exercise. The formula we need is:

Where
is the raw score,
is the mean and
is the standard deviation.
We know at that time heights of men had a mean of 170.53 centimeters and a standard deviation of 5.91 centimeters, then:

Knowing that the tallest living man at that time had a height of 230 centimeters, we get:

And knowing that the shortest living man at that time had a height of 91.3 centimeters, we get:

Based on this, we can conclude that the shortest living man at that time had the height that was more extreme.
Answer:
