Answer:
P(A) = 0.57 (to the nearest hundredth)
Step-by-step explanation:
There are 7 letters in total
4 of them are the letter A
⇒ P(A) = 4/7
= 0.5714285714...
= 0.57 (to the nearest hundredth)
Answer:
d. 90 cm, 1.2 cm
Step-by-step explanation:
Given that:
The sample size n = 36
For the length of the link:
The mean
= 2.5
The standard deviation s = 0.2 cm
In a chosen 36 links, The mean and standard deviation for the length chain is as follows:
Mean = n
Mean = 36×2.5
Mean = 90 cm
The Standard deviation = s×√n
The Standard deviation = 0.2×√36
The Standard deviation = 0.2×6
The Standard deviation = 1.2 cm
