you get the answer and then simplify it to become a mixed number
Answer:
Expected Number=71
Variance =4959
Standard Deviation= 70.42
Step-by-step explanation:
Expected Number = E (x) = np
Here p = 0.71 and q= 1- 0.71= 0.29 n= 100
Expected Number = E (x) = np = 0.71*100= 71
b) The Variance and Standard Deviation for the number of these tweets with no reaction
Suppose the number of tweets are hundred then the number of tweets with no reaction would be 71 .
Variance = E(x²) - [E(x)]² = (100)²- (71)²= 10000- 5041= 4959
Standard Deviation= √4959= 70.42
To compare two fraction you need to rewrite the fractions so they have a common denominator.
1/2 should have been rewritten as 4/8
The answer is:
D. The fraction 1/2 should have been rewritten as 4/8.
Let x represent the number of plants that they will sell in five hours
We were told that the garden store sells six plants per hour. This means that
6 plants = 1 hour
then,
x plants = 5 hours
By cross multiplying, it becomes
x * 1 = 6 * 5
x = 30
They will sell 30 plants in 5 hoursx
