Jacob’s daily tips this work week were $99, $78, $58, $91, $90, and $68. Is Jacob correct in thinking that the mean best represe
Neko [114]

Answer:

D. No, Jacob is not correct. The median amount he makes is $84.00 in a day.

Step-by-step explanation:

In this case, the mean is not the best measure of this data.

We can see that there is one value lower than the rest, $58.  This brings the mean down.

With the value of $58, the mean is $80.70.  If we were to take this value out, the mean would be $85.20, which is higher.

Since the mean is brought down by this value, we should use the median.  The median of this data set is $84.

The range of the function y = 2cos x is -2 ≤ y ≤ 2.
Vadim26 [7]

<u>Answer:</u>

The range of the function y = 2cos x is -2 <y < 2 .

<u>Step-by-step explanation:</u>

We know that cos (0) = 1 and cos (π) = - 1 are the two extreme values which cos x assume when x ∈ R and it is also that cos (x) is a continuous periodic function with period 2π when x ∈ R ,

since ,

cos (x + 2π) = cos x

So, the range of the  function y = 2cos x is -2 <y < 2 .
