Answer: 0.0386
Step-by-step explanation:
Number of digits = 10
Number of letters in English alphabet = 26
Total number of characters = 
Now, if replication is allowed, then the total number of ways to make a ten character password will be :_
The number of ways to make a password having all letters :-
Now, the probability that the password will contain all letters will be :-
Hence, the probability that the password will contain all letters =0.0386
Answer:
y = 105 ÷ 6 = 35/2
Step-by-step explanation:
∵ 15/3 = 2y/7
∴ 2y × 3 = 15 × 7
∴ 6y = 105
∴ y = 105 ÷ 6 = 35/2
Answer:
The confidence interval for a population mean proportion mean should be constructed because the variable of interest is time to complete the round, which is a quantitative variable.
Step-by-step explanation:
A researcher with a golf association obtained a random sample of 25 rounds of golf on a Saturday morning and recorded the time it took to complete the round.
Time is the number of hours, so it is mean, and not proportion.
Variable of interest is time to complete the round, and since it is measured in hours it is a quantitative variable.
The answer is:
The confidence interval for a population mean proportion mean should be constructed because the variable of interest is time to complete the round, which is a quantitative variable.
To begin, let's take a relatively simple example.
Make x the subject of the formula:
4y + 2 = x - 4.
x = 4y + 6.
Make y the subject of the formula.
2y/5 - 3x = 2.
TIP: Remember to put brackets around 2 + 3x because both the 2 and the 3x are being multiplied by 5.
y = 5 + 15x/2.
