Answer:
56
Step-by-step explanation:
Arithmetic mean is simply the sum of the all the number present divide by the total number.
From the question, we obtained the following information:
The arithmetic mean = 5.6
Total number present = 10
Sum of the numbers =?
Arithmetic mean = sum of the numbers / total number
Sum of the numbers = arithmetic mean x total number
Sum of the numbers = 5.6 x 10 = 56
Answer:
4
Step-by-step explanation:
Decreasing a percentage from a number can be done by multiplying said number and percentage together. That being said:
16 * 25% = 4
Meaning that the result of the number 16 being decreased by 25% is 4
The slope will always be next to X when the equation is in slope intersect form (y=mx+b). So the slope in that equation is -1/2.
I think the correct answer might be A or D
