The answer is D.$12.15
5(1.29)+10(1.49)+2(1.25)+4(6.00) =$47.85
$60-$47.85 = $12.15
8>w
w>/= -3
Meaning the inequality is 8>w>/= -3
Answer:
Option D) a = 36, b = 36
Step-by-step explanation:
We are told in the question that Hassan predicted that he would sell 178 postcards. He actually sold 142 postcards.
In the diagram above,
a = Error
b = Absolute Error
Error in mathematics is calculated as:
Approximately or Predicted value - Actual value
For Hassan,
His predicted value = 178
Actual value of postcards sold = 142
Error = 178 - 142 = 36
Likewise, the formula for Absolute error Absolute Error = |Actual Value - Measured or predicted Value|
It is important to noted that Absolute Error is always positive
Actual value = 142
Predicted value = 178
Absolute Error = |142 -178|
= |-36|
Absolute Error is 36
Therefore, Option D) a = 36, b = 36 is the correct option.
Hello there!
Let's look at the graph. If we do the vertical line test, we can figure out that YES, it is a function, so option b and c are already out of the picture.
Now, to find the domain, look at the graph and shade it back to the x-axis. The domain includes every number greater than 3, so the domain is x>3.
To find the range, take a look at the graph and shade it back to the y-axis. The range includes every real number greater than 0, so the range is y>0
This means that d is the answer.
I really hope this helps!
Best wishes :)
