The second option - 3/25.

The probability of the first one is 3 blue socks over 10 socks in total = 3/10
The probability of the second one is 4 red socks over 10 socks in total = 4/10

Multiply the two probabilities to get the probability of having the first sock as blue and the second sock as red.

3/10 * 4/10 = 3/25

First sock being blue is 3/10
Second sock being red after blue is chosen first is 4/10, because of replacement

3x4=12
10x10=100

divide by 4 to get 3/25

Is y=-2/5x inverse or direct variation

liraira [26]

Answer:

direct

Step-by-step explanation:

The standard form of an equation representing direct variation is

y = kx ← k is the constant of variation

The standard form of an equation representing inverse variation is

y = $\frac{k}{x}$ ← k is the constant of variation

y = - $\frac{2}{5}$ x ← represents direct variation with k = - $\frac{2}{5}$
