Answer:
11,800 different four letter permutations can be formed using four letters out of the first 12 in the alphabet
Step-by-step explanation:
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
In this question:
Permutations of four letters from a set of 12 letters. So
11,800 different four letter permutations can be formed using four letters out of the first 12 in the alphabet
Answer:
for a) the following answers are in order from left to right.
5, 2, 2, and 10
for b) this is the square root of three: 1.73205080757 [u can round it to the first decimal place urself! :)]
Step-by-step explanation:
b) 4 = x^2 + 1
4 - 1 = x^2 - 1
3 = x^2
so the sqaure root for 3 is 1.73205080757
Answer:
0.545
Step-by-step explanation:
In the missing table the following information is shown:
Did You Watch More Than One Hour of TV Last Night?
3rd Period Class: Yes- 11 No- 6
6th Period Class: Yes- 12 No- 10
The probability that the student watched more than 1
hour of TV given that he/she belongs to 6th period class is:
P(more than 1
hour of TV | 6th period class) = 12/(12+10) = 0.545
Answer:
2,856,271
Step-by-step explanation:
We presume your equation is intended to be ...
P = 1,030,000(1.12)^t
To find the prediction in 9 years, put 9 where t is and do the arithmetic.
P = 1030000(1.12^9) ≈ 2,856,271
In 9 years, the population is predicted to be about 2,856,271.
3,000 = 3 x 10 x 10 x 10 = 3 * 10^3
--------------
10^3 * 3 * (640)
= 10^3 * 3 * (600 + 40)
= 10^3 * (1800 + 120)
= 10^3 * 1920
= 1,920,000
