Answer:
The probability is 2.2%
Step-by-step explanation:
The probability that a randomly selected adult uses the telephone in classes is always equal to 0.48.
If x represents the number of adults selected from among the 8 that the telephone uses in classes, then x is a discrete random variable that follows a binomial distribution, with:
p = 0.48
q = 0.52
n = 8
We want to find the probability of x = 5
The probability is 2.2%
If N and A are defined, you multiply the value of N by the value of A.
Answer:
He can feed 200 plants
Step-by-step explanation:
To solve this, we will follow the step below:
first, convert 25 g to kg
25 g = 25/1000 = 0.025 kg
Now using proportion to solve;
Let x be the number of food plant he can feed the plant
0.025 kg = 1
5 kg = x
cross-multiply
0.025×x = 5×1
0.025x =5
Divide both-side of the equation by 0.025
0.025x/0.025 = 5/0.025
x=200 plants
Therefore, he can feed 200 plants
