26,000 divided by four equals 6,500, and if for every four roses there were 5 then you would multiply 6,500 by 5 to get 32,500 snapdragons
Information provided:
Sample size, n = 30 students
P(Male), P(m) = 55% = 0.55
P(Female), P(f) = 45% = 0.45
Now,
Mean = nP(m) = 30*0.55 = 16.5 ≈ 17 students
Variance = (sd)^2 = nP(m)P(f) = 30*0.55*0.45 = 7.425 ≈ 8 students
Answer: 720 mph or 12 miles a minute
Step-by-step explanation:
Given:
Ratio of tulips to roses = 2:1
Total number of flowers = 18
To find:
The number of tulips.
Solution:
Let the number of tulips and roses are 2x and x respectively.
According to the question,


Divide both sides by 3.


Now,
Number of tulips 

Therefore, the number of tulips is 12.
