Answer:
B. Metric measurements are based on powers of 10; customary measurements are not.
Step-by-step explanation:
You share only one distribution, so we'll focus on that one: mean: 30; std. dev.: 4.
Draw a "standard normal curve." Draw a vertical line in the exact middle of your curve. Label this line "30." Now "one standard dev. above the mean" is 30+4=34; "two std. devs. above the mean is 30+4+4=38, or 30+8=38. "three std. devs. above the mean is 30+3(4) = 42.
Now work in the other direction. Start with the mean: 30. But now subtract the std. dev. (4) instead of adding it. You'll get 30-4=26. This is "1 std. dev. below the mean. Continue: find 2 and 3 std. devs. below the mean.
No it’s not that’s the wrong answer
Take any 2 points, so we'll us (2,16) and (4,32)
then do y2-y1/x2-x1
so 32-16=16
4-2×2
so then do rise(y) over run(x)
so the slope is 16/2 which simplifies to 8
so the rate of change is
y=8x
First one has parentheses, second one doesn't.<span />
