The probability that a radish seed will germinate is 0.7. A gardener plants seeds in batches of 12. Find the mean for the number of seeds germinating in each batch.

mean = 8.4

Step-by-step explanation:

Mathematically, we have the mean as np

This is the product of the number of items per batch by the probability that each of the products will germinate

Mathematically, we have this as:

0.7 * 12 = 8.4

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
