Answer: Efficiency metrics
Step-by-step explanation:
From the question, we are informed that Cory Randle tracks the performance of his system by tracking the response time it takes to respond to Twitter posts mentioning the news station, and as the speed and accuracy of content that are posted on numerous websites and social media sites.
The type of metrics that Cory is using to measure his system is efficiency metrics. It should be noted that this is to determine how efficiently a company is using its resources whether the resources are being used well or they're inefficiently used and wasted. The metrics can also be used to determine how effective management is.
Answer:
The length of the pencils is 4.1 inches and for the crayons 1.5 inches
Step-by-step explanation:
We can solve by means of a 2x2 system of equations, we have to:
let "x" be the length of the pencils
let "y" be the length of the crayons
4 * x + 3 * y = 20.9
5 * x + 4 * y = 26.5 => x = (26.5 - 4 * y) / 5
Replacing:
4 * (26.5 - 4 * y) / 5 + 3 * y = 20.9
21.2 - 3.2 * y + 3 * y = 20.9
-0.2 * y = 20.9 - 21.2
y = -0.3 / -0.2
y = 1.5
now for x:
x = (26.5 - 4 * 1.5) / 5
x = 4.1
This means that the length of the pencils is 4.1 inches and for the crayons 1.5 inches
It would be $18.94, because the hundredths place is the penny.
