The barrel had 20 liters....after 24 hrs, it had 14 liters......that means in 24 hrs, it leaked (20 - 14) = 6 liters....so it is leaking 6 liters every 24 hrs
liters / hr = 6/24 = 0.25.....so it is leaking 0.25 (or 1/4) liters per hr
Answer:
<em><u>Males:</u></em>
<em>10.4%</em> have green eyes.
<em>33.3%</em> have blue eyes.
<em>56.3%</em> have brown eyes.
<em><u>Females:</u></em>
<em>7.5%</em> have green eyes.
<em>47.5%</em> have blue eyes.
<em>45%</em> have brown eyes.
<em>Explanation: </em>
To find each percentage, we have to <em>count up the amount of people for each gender</em>. When we have the males, we <em>add them up</em> and we get <em>48 males</em>. Now lets take <em>green eyes and divide it by 48</em>, since <em>5 ÷ 48</em> 0.1041666666666667, we now multiply that number by 100 and we get <em>10.41666666666667</em>. Now round that number to the nearest ten and we get <em>%10.4.</em> Now you know the formula, I hope you understand it. :)
Sorry I don't know the answer
It is the standard deviation without squaring it.
Basically it tells you how spread out from the mean your group of numbers is.
Here's how to do it:
Step 1: find the mean (add all numbers together, divide by how many numbers there are)
Step 2: subtract each number in the list from this mean
Step 3: take the absolute value of each number (so they are all positive numbers)
Step 4: find the mean of these new numbers
That's the Mean Absolute Deviation!
The best answer i think would get is C i hope im right
