unit rate would be miles per hour
so divide 210/3 = 70
Te difference of 2 standard deviation of a population n1 & n2 is given by the formula:
sigma (difference)=√(sigma1/n1 + sigma2/n2), Plug:
sigma(d)= √(49/100 + 36/50)
Sigma(d=difference) =1.1
Answer:
85+(5x-10)=11x+3 (sum of two non-adjacent interior angle is equal to exterior angle )
75+5x=11x+3
75-3=11x-5x
6x=72
x=72/6
x=12
Multiply 3x by -6, it gives you -18 so I'm going to say D
