I'm learning geometry right now if you could be more specific I might be able to teach you a few things.
Answer:
D (last one)
Step-by-step explanation:
You figure out the ordered pair for E which is (3,-4)
Then you apply the rule given in the instructions.
so you do 3+8= 11 so x = 11
then -4+5= 1 so y = 1
So you get (11,1)
Answer:
247.666667
Step-by-step explanation:
Answer:
1. 25
Step-by-step explanation:
First, you need to place the numbers in ascending order, meaning from smallest to largest.
You calculate the range by taking the largest number and subtract the smallest from it, so in this case: 42-17 = 25
Mean (average), just add the numbers up and divide by how many numbers you have
III. Once you find the Mean and you placed them in order from smallest to largest, you can find this answer
Median (middle) - which number is in the middle so after you place them in order which is in the middle if you have an odd number of marks, but since you have 12 marks then take the 2 center numbers, add them up, and divide by 2, in other words, get the mean of the middle numbers and that will give you the median in this problem
Mode, which number appears the most times repeated
Answer:
B
Step-by-step explanation:
30-3.12=26.88 divide that by 4 and you get 6.72
