Answer:
y = 4x + 4
Step-by-step explanation:
If this equation is parallel to y = 4x + 2, that means it would have the same gradient. And since the y-intercept is stated, you just need to put it next to the gradient
Answer:
Mean = 13 kilometer per second
Standard Deviation = 0.4082 kilometer per second
Step-by-step explanation:
We are given the following data set of rocket speed in kilometer per second in the question:
12.7, 13.4, 12.6, 13.3
Formula:
where are data points, is the mean and n is the number of observations.
Deviations from mean = -0.3, 0.4, -0.4, 0.3
Sum of squares of differences =
0.09 + 0.16 + 0.16 + 0.09 = 0.5
Mean = 13 kilometer per second
Standard Deviation = 0.4082 kilometer per second
Answer:
15%
Step-by-step explanation:
55%-40% = 15% cocoa.
One may note, you didn't really include any "of the folllowing" ones
anyway... if we take the 3000 as the 100%, what's the 40% of that?
well
solve for "x"
Total cars 12+54 = 66
Find percentage of minivans.
12/66 = 0.1818 or ~18%
~18% of 77
77* 0.1818 = 13.999 ~ 14 rounded
