  • A: 75,463.12
  • B: 74,124.87
  • C: 76,095.71

1. It should be no trouble to determine that the largest mean belongs to Cathy.

2. The mean is the average of the given 2SD limits, so is ...

  (67,785.08 +83,141.16)/2 = 75,463.12 . . . . matches Amanda

Please note that you only need to work with about 3 significant figures:

__

3. The mean is the average of the given 1SD limits, so is ...

  (70.1 +78.2)/2 = 74.15 . . . . matches Benjamin

Use words to write a comparison statement for the problem above.
pantera1 [17]

Looking at the question we can see that it says:

41253>35214

We should know what these symbols mean:

stands for something less than the other, for example:

We can say that 2 is less than 5 so in a symbolic form it can be written as,

2

Similarly,

> stands for something greater than the other, for example:

We can say that 7 is greater than 5, in a symbolic form it can be written as,

7>5

So here, 42153>35214 means that, 42153 is greater than 35214.

F(x)= -2x + 2; Find f(5)
zhuklara [117]
If f(x) = -2x + 2, f(5) can be found by substituting in the value 5 for x in the equation:

f(5) = - 2(5) + 2

Our first step in simplifying this expression is to perform the multiplication as outlined by the order of operations (PEMDAS).

f(5) = -10 + 2

Finally, we must get our final answer by adding together the remaining terms.

f(5) = -8

Hope this helps!
