Answer:
0.93
Step-by-step explanation:
Answer:
okay so im not sure which is being round so i'll do both
if you are going to round the miles and gallons:
278.2 to 278 because the decimal is below 0.5
19.6 to 20 because the decimal is above 0.5
278/20 = 13.9 which you would round to 14 because the decimal is above 0.5
if you are only going to round the answer:
278.2/19.6 = 14.193877551 which you would round to 14 because the decimal is below 0.5
so regardless of what you do, <u> your answer will be 14</u>
Memorize the definition of standard deviation: the sd is the square root of the average of the squared deviations of the mean. Wow. Let's do it.
Step 1. First we need the mean. That's easy. Add them up and divide by the count. Check if you get 16.88/5 = 2.81333.
Step 2. Now we're going to subtract this from each of the values, and square the result. Don't worry about negative signs, the squaring will get rid of those. Example for the first number:
(1 - 2.813)^2 = 3.29
The list of numbers I get is (rounded, in reality round as little as possible):
3.29, 2.60, 1.41, 2.35, 1.66, 6.18
Step 3: Add them all up. I get 17.49.
Step 4: Divide by the count of numbers. 17.49/6 = 2.91
Step 5: Take the square root from this result. SQRT(2.91) = 1.707305
TIP: Use excel to do all these steps, then run the set of numbers through Excel's built-in sd function (called STDEV.P) and see that you get the same result!
Answer:
(x + 0, y − 2), reflection over y = 1
Step-by-step explanation:
H will be shifted down 2 units and then reflected over y = 1, which maps H into itself
