Determine the expression for s
The speed is calculated as:
Substitute S for speed
Let the number of books be b and the time be m.
The expression becomes
Hence, the expression for the scenario is:
The function that is positive for the entire interval [–3, –2] is the graph of the function (b)
<h3>How to determine the function?</h3>
See attachment for the proper representation of the available options
For a function to be positive on the interval [-3,-2];
It means that the y values must be in the positive quadrant from x = -3 to x =-2
From the list of options, we have:
The y values from x = -3 to x =-2 is at the positive quadrant for the second graph i.e. option B
Hence, the function that is positive for the entire interval [–3, –2] is the graph of the function (b)

Answer:
C: x = 10
Step-by-step explanation:
PO = QR (so having equal central angles)
Now
4x-11 = 2x+9
4x-2x = 9+11
2x = 20
Dividing both sides by 2
x = 10
105.00 i think cuz 40 is rounded backwards
Answer:
We cannot infer a cause and effect relationship because the treatments imposed were not blocked correctly.
Step-by-step explanation:
The treatments given to the groups given in the question where not assigned proper treatments to establish proper randomized block design.
Thus, we can say the conclusion is that we can't truly infer a cause and effect relationship as the blocks were not properly done.
