Answer:
D
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is

Here { a, b ] = [ - 1, 2 ], thus
f(b) = 4 ← from (2, 4 )
f(a) =
← from (- 1,
) , thus
average rate of change =
=
=
→ D
Answer:
<em>44, definition below</em>
Step-by-step explanation:
- An outlier is a number that is much larger or smaller than the general populous of numbers. For example, if there was a dot plot with dots clustered at 2, 3, and 5, but there was one or two dots around 10, then 10 would be considered an outlier.
- I would consider 44 to be an outlier in the number set.
If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers. Have an amazing day.
The most important part of this question is understanding the words of the problem. The trick lies in the words of the problem. Once the web of words is simplified, the problem becomes very easy. The main thing is converting the words into numbers.
Let us assume the unknown number = x
Then from the question we get
(x/4) = (x/5) + 1
(x/4) - (x/5) = 1
(5x - 4x)/20 = 1
x/20 = 1
x = 20
So the unknown number is 20
I think the most likely representative sample had more girls than boys that were surveyed for it.
Answer:
103.5
Step-by-step explanation:
13 + (43 ÷ 2) × 5 - 17
13 + 21.5 × 5 - 17
13 + 107.5 - 17
107.5 - 4
103.5
