Answer:
B.
Step-by-step explanation:
Range is all the set y values.
Hey Jay,
Since we can't see the graphs, we can't be entirely sure, but given that we are trying to model the population size of a species of bird that is slowly going extinct. I would say the best graph would be a line graph. Line graphs show changes over time so this would be the best graph to use. Hope this helped!
Cheers,
Izzy
The expression can be solved by expanding the bracket and multiplying out the terms
Therefore, the expression can be simplified as;
Alternatively, using the theorem of difference of two squares, which is
Hence,
Answer:
x (blue circle thing) = 46
y (dna) = -63
z (molecules) = 52
Step-by-step explanation:
Answer: standard deviation = 8
This is because mu = 75 is the mean, which is at the very exact center of this distribution. One space to the right is 83, which is 83-75 = 8 units away from the center. This distance is exactly one standard deviation. We can say "83 is one standard deviation larger than 75".
Or you could note the distance from 67 to 75 is also 8, because 75-67 = 8. Each tickmark represents stepping one standard deviation in distance.
