Since x and y are directly related, the equation for their comparison will look like
kx = y
where k is your constant. They give you an instance in the problem where x = 27 and y = 81. Plug this into the above equation and solve for k.
kx = y
k (27) = 81
k = 3
Thus, the constant of variation is 3.
√80 because the absolute value for complex numbers of the form a+bi are evaluated as √a²+b²
Answer:
130 balloons
Step-by-step explanation:
295-100= 195
195/1.5=130
Answer:
A and B in a sample space S, but assume that Pr[A] = 0.25, Pr[B] = 0.15, and Pr[A∩ B] = 0.1.
Step-by-step explanation:
pr[A/B]=pr[AnB]/pr[B]=0.1/0.15=0.666
pr[B/A]=pr[BnA]pr[A]=0.1/0.25=0.4
