20, 100
Step-by-step explanation:
You look at the tens column, in this case the numbers would be "7" in the "671" and the "3" in the "32". If you're rounding the tens column you look at the ones column and if the number is bellow 5 you round down, if its 5 nd over you round up. Since the number is 1 in the ones column that means the 7 will round down so it would be "670", for "32" the number is "2" (which is bellow 5) so we will round down again to "30". This will leave you with the equation 670×30 which is 20, 100.
Answer:
the standared deviation =2.87 so it is small
Step-by-step explanation:
to calculate the standard deviation of those numbers:
1- Work out the Mean (the simple average of the numbers)
(7+6+5+8+9+1+0+4+3+2)/10=4.5
Then for each number: subtract the Mean and square the result.
[(7 - 4.5)^2 + ... + (2 - 4.5)^2]/10=8.25
√8.25=2.87≅3

Answer: Height = 8 m
Step-by-step explanation: We have to find h...
We're given two values
A = 60
B = 15
60 is equal to 1/2 x 15
Solve for h:
h = 60 / (1/2 x 15)
h = 60 divided by 7.5
h = 8
I hope this helps!
