Vicki measured the midnight temperatures in 4 locations in Alaska. The temperatures were -7, -2, 1, 4. What is the mean absolute deviation of the temperatures?

The mean is -1

Answers

Answer 1
Answer: 1. Find the mean of the data: (-7 -2 + 1 + 4)/4 = -1

2. Find the absolute value of differences between each data an the mean:

1) |-7 -(-1)| = |-7 + 1| = |-6| = 6
2) |-2-(-1)| = |-2+1| = |-1| = 1
3) |1 -(-1)| = |1+1| = |2| = 2
4) |4 -(-1)| = |4+1|=|5|=5

3) Calculate the mean of those differences:

( 6 + 1 + 2 + 5) / 4 = 14/4 = 3.5

A digital camera for $249.99 at 4% sales tax

Answers

First, change the 4% into a decimal. Once thats changed, it will be 1.04
Multiply 1.04 by the amount of the cost, to get your answer.
But, to make this easier, and to not go through more work, lets round your money amount to $250
Now, all you have to do is multiply.
$250 · 1.04 ≈ $260
So, your answer for $250 with 4% (1.04) percent sales tax would be a grand total of:
$260

-Hope this helped :)
i'll round the 249.99 to 250 for simplicity 
250*1.04=260 or 259.9975 if you want to be technical

A particular strain of a common bacteria replicates itself every 14 minutes. Which of the following does this situation represent? A. neither a relation nor a function B. both a relation and a function C. a function only D. a relation only

Answers

Every 14 minutes, a type of bacteria reproduces itself. The whole situation represents also a relationship and a function. It multiplies itself all the 14 minutes, that is an exponential function.

  • Relation between 2 sets would be a group of ordered pairs containing 1 item from each set.
  • When item x is from the first set as well as the object y is from the second set, the objects are said to be related if the item set (x,y) is now in the relation.
  • A functional in math is a binary connection between two sets that associates each element of the first group with exactly one member of the opening pair.

Therefore, the final answer is "Option B".

The center of rotation is point P. Which describes the rotation of ΔABC to form ΔA'B'C'?A.
clockwise 270°


B.


clockwise 360°


C.
counterclockwise 180°


D.
counterclockwise 90°

Answers

Answer:

C. counterclockwise 180°

Step-by-step explanation:

Hi! A and B are definitely not the right answers, because that’s basically rotating it forward even more. Rotating a polygon in Quadrant II 370 degrees clockwise is like rotating it 99 degrees counterclockwise, because the next 90 degrees you were to rotate it, it would be in it’s original position. The answer is C.
