Set up a proportion
2 x
— = —
25 700
700(2)= 25(x)
1400/25=x
x=56
0.6222... is a recurring decimal at the digit '2'
let x = 0.62222....
multiply x by 10 ⇒ 10x = 6.2222.... [we multiply by 10 to leave the recurring digits after decimal point]
multiply x by 100 ⇒ 100x = 62.2222... [we multiply by 100 so that we can again leave the recurring digit after decimal point]
subtract 10x from 100x
100x - 10x = 62.2222... - 6.2222...
90x = 56
x = 56/90
x = 28/45

Answer:
2e⁻² ≈ 0.271
Step-by-step explanation:
This is actually a Poisson distribution. The probability is:
P(x; μ) = e^(-μ) (μˣ) / x!
P(2; 2) = e⁻² (2²) / 2!
P(2; 2) = 2e⁻²
P(2; 2) ≈ 0.271
Answer:
(C) is 0.14 that is your probability
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Descriptive statistics describe an event that happens over time. So bowler striking on 1/5 of his throws that night would be an example of descriptive statistics.
