144 I believe. You multiply length times width
Answer:91
Step-by-step explanation:
If the best grade is 100,91 is it.
Since both trapezoids are similar, so LMNO is a scaled version of QRST by some magnitude
so we can easily use the concept of ratios to find x
in other words: x÷2=6÷5
so x=6×2÷5=12/5=2.4
x=2.4
This seems to be dividing by 4, so the next numbers are 20, and then 5. If there is a 3rd, it's 1.25
Answer:
or 1.414
Step-by-step explanation:
1) Find the mean. 1+2+3+4+5 = 15. 15/5= 3
2) For each data point, find the square of its distance to the mean. (4, 1, 0, 1, 4)
3) Sum the values from Step 2. 10
4) Divide by the number of data points. 10/5= 2
5) Take the square root.
