The total number of possible PINs' that you can make is; 74,088,000 PINS
How to solve probability combinations?Each of the first 3 letters can be chosen from the 21 letters since 5 vowels cannot be used, {A, B, C, …, U, V, W}.
Thus, number of possible choices = 21³ possible choices.
The first 3 digits can be any number from {0, 1, 2, …, 9}, so there are 10³ choices.
The last digit cannot be 0 or 9, so you can select from {1, 2, 3, …, 8} which gives 8 choices.
Then the total number of PINs that you can make is; 21³ × 10³ × 8 = 74,088,000

1/3x-1/6y=4 6x-ay=8 in the system of equatuons above, a is a constant. if the system has no solution, what is the value of a?
Answer:
3
Explanation:
(1/3x-1/6y)×18=4×18 ⇒ 6x-3y=72
6x-ay=8 if a=3 ⇒ 6x-3y=8
72≠8
a=3 ⇒ system has no solution
The lengths of a particular snake are approximately normally distributed with a given mean = 15 in. and standard deviation = 0.8 in. what percentage of the snakes are longer than 16.6 in.? 0.3% 2.5% 3.5% 5%
Answer: The answer would be 5%
Explanation:
The closest answer choice is 2.5%, which is the closest value to 1.7% given in the answer choices.
What is z-score?The Z-score is a statistical measure that describes the relationship of a value to the mean of a group of values.
To solve this problem, we can use the standard normal distribution and the z-score formula:
z = (x - μ) / σ
Where x is the value we want to find the probability for, μ is the mean of the distribution, and σ is the standard deviation of the distribution.
In this case, we want to find the percentage of snakes that are longer than 16.6 in., which corresponds to a z-score of:
z = (16.6 - 15) / 0.8 = 2.125
Using a standard normal distribution table or calculator, we can find that the percentage of values in the distribution that are greater than a z-score of 2.125 is approximately 1.7%. Therefore, approximately 1.7% of snakes are longer than 16.6 in.
Thus, the probable answer is 2.5%.
