The correct answer for the question that is being presented above is this one:
<span>
To find the mean of a set, add up all of the numbers and divide by how many numbers you have. For the first set:
</span>u = (10.7+2.4)/2 = 6.55
For the second set:
u = (13.7 + 2.5)/2 = 8.1
<span>To find the mean absolute deviation, (MAD) find the mean of the distances of each number from the mean.
</span>First set:
MAD = (|10.7-6.55| + |2.4-6.55|)/2 = 4.15
Second set:
<span>MAD = (|13.7-8.1| + |2.5-8.1|)/2 = 5.6</span>
The means-to-MAD ratio is simply that, divide one by the other and that's it.
For the first set:
6.55 / 4.15 = 1.57831325
For the second set:
8.1 / 5.6 = 1.44642857
<span>8.4. To come to this conclusion, one must remember that 1/10 of a number is in essence saying this is 1 out of 10 equally divided portions of a number. This is equivalent to 10%. Multiply the number by the denominator, in this case 10, and you will get the total number.
0.84 x 10 = 8.4 (10% x 10 = 100%). Another way to look at it is to add 0.84 ten times. Either way you should end up with 8.4.</span>
Answer:
A. For both Me and My sister it is going up by one, but my sister and I have a 2 year difference from each other, every time.
B. 10 years old
C. I know this because for every year old I am my sister would be 2 years old than me.
D. When you turned 16 your sister would have been 18 by then.
E. I know this because as the years keep going up the trend is still the same as I will always have a 2 year difference from my sister.
F. No you would not need to extend the table to figure out the answer as all you would have to do is take your age and add 2 to it to get your sisters age.
Step-by-step explanation:
It is a constant trend so whenever you want to figure out your sisters age in this problem you would just have to add 2 to you current age in order to find out how old she is.
Answer:
48
Step-by-step explanation:
25% of x = 0.25
12/0.25 = 48
If the can is 20oz and cost $25.40, the price per ounce would be:
price = $25.40
ounce = 20oz
so:
which comes out to be:
$1.27/oz
So each ounce of tomato sauce costs $1.27!
