Answer:
38 seeds will grow
Step-by-step explanation:
4/5 = 80%
80% = .8
40*0.8 = 32
−3x + 6 = 5 | -6 (first step is: "subtract 6 from both sides" <span>)
</span>
-3x = 5-6
-3x = -1 | /(-3) (second step is: "<span>divide by (-3) on both sides</span>" <span>)

Answer:
D.) The expected value is 1.78
Step-by-step explanation:
The expected value of a probability distribution is evaluated using the formula.
Expected Value, 
Therefore, from the given probability distribution, we have:
E(X)=(0*0.3)+(1*0.2)+(2*0.16)+(3*0.2)+(4*0.04)+(5*0.1)
E(X)=1.78
The Expected value of X is 1.78.
The correct option is D.
