Answer:
89
Step-by-step explanation:
Hi, there to find the mean
you need add the numbers and count how many numbers are there and divide
In this case 98+78+84+96= 356
Now we will count
there are 4 numbers
= 89
Your mean will be 89
If you ever have trouble with mean remember this
Mean
well it is supposed to be:
Sum of Data Points/Number of Data Points
Answer:
-9
Step-by-step explanation:
Answer:
7
Step-by-step explanation:
4x-3 ≥ 5
4x ≥ 5+3 (add 3 to both sides)
x ≥ 8/4 (divide both sides by 4)
x ≥ 2
a is the answer.
_____________________
3x-5 ≥ 7
3x ≥ 7+5
x ≥ 12/3
x ≥ 4
b is the answer
so, did you understand?
width = 13
length = 30
p=2l + 2w
86 = 2(2w+4) + 2w
86 = 4w + 8 + 2w
86= 6w + 8
78 = 6w
13 = w
86 = 2l + 2(13)
86 = 2l + 26
60 = 2l
30 = l
check your work.
l is 4 centimeters more than twice w
twice w = 26
plus 4 = 30
i hope you understand. ask questions if not
