Answer:
<em><u>3x + 5y = 7</u></em>
Step-by-step explanation:
Supplementary angles because because angle 1 + angle 2 = 180° so they form a line
3 and 2/9. You just multiply 9 by 3 to get 27 and put the remaining 2 over 9
The empirical rule states that at 95% the measurements would be within 2 standard deviations of the mean.
You are given a mean of 68 inches and a standard deviation of 4.
2 times the standard deviation = 2 x 4 = 8
So 95% of the heights would be between 68-8 = 60 inches and 68+8 = 76 inches.
