Answer:
y=6x
Step-by-step explanation:
direct variation equation is like y=kx (k: constant)
substitute (5,30) to solve k,
30=5k
k=6
Answer:
0.218
Step-by-step explanation:
Answer: The correct probabilities is about 0.1192.
To start we need to find the standard deviation, it is the square root of the variance or 7.
Now, we need to find the z-score of a value that is 1.05 months above the mean.
1.05 / 7 = 0.15 produces a value of 0.5596. Since we are dealing with a range from 0.15 below and above the mean, we have 0.0596 to the right of the mean and the same below the mean.
0.0596 x 2 = 0.1192
We have
/*5 multiply both sides times 5
6x-1=3*5
6x-1=15 /+1
6x=15+1
6x=16 /:6
x=
