<u><em>Answer:</em></u>
A piece of oak is longer than a piece of maple
<u><em>Explanation:</em></u>
<u>1- For the maple:</u>
We know that the total length of the maple is 4.56 meters and that this length is equally divided into 4 pieces
<u>Therefore:</u>
Length of each maple piece = meters
<u>2- For the oak:</u>
We know that the total length of the oak is 3.69 meters and that this length is equally divided into 3 pieces
<u>Therefore:</u>
Length of each oak piece = meters
<u>3- Comparing the length of the pieces:</u>
<u>We now calculated that:</u>
length of maple piece is 1.14 meters
length of oak piece is 1.23 meters
We can compare the two values using the number in the <u>tenth position</u>
<u>Therefore:</u>
1.23 > 1.24
which means that one piece of oak is longer than one piece of maple
Hope this helps :)

Step-by-step explanation:
Speed of Rachel is 38m/s.
Step-by-step explanation:
- Step 1: Given equation for distance D = 38t + 220
- Step 2: Formula for Speed = Distance/Time
- Step 3: Differentiate the formula for distance with respect to time to find speed
⇒ Speed = d/dt(38t + 220) = 38

3. Correlation coefficients can be represented by the variable r
Step-by-step explanation:
Correlation coefficients show if there is a strong or weak positive or negative relationship, or if there is no relationship between the variables.
Correlation coefficients are negative when the relationship is inversely proportional and positive when the relationship is proportional.
Correlation coefficients can be any value less than or equal to 1 or greater than or equal to -1.
