Answer:
-3
Step-by-step explanation:
f(x)=2x+1
f(-2)=2(-2)+1=-4+1=-3
1. Total number of marbles=10 red marbles+80 green marbles+110 orange marbles=200 marbles
2. Let's call "V" the event that consists that he selects a green marble from the bag. Then:
P(x)=80/200
P(x)=0.4
3. This problem can be represented by a binomial distribution, where:
P=0.4
q=1-P=0.6
n=50
4. The expect value in a binomial function is written as below:
E(x)=nxP
E(x)=50x0.4
E(x)=20
The answer is: He can expect 20 zucchini.
Answer:
40%
Step-by-step explanation:
0.4=0.40
0.40×100
=40%
