Answer:
Step-by-step explanation:
First you distribute so two times 4Y is 6Y then you multiply the two in the five which gives you 2Y -5 equals 70
Answer:
(728, 748)
Step-by-step explanation:
You need the Z value which for 95% confidence interval is 1.96. The mean is $738 and the standard deviation of $41.
Therefore we can calculated the confidence interval
The interval is (728,748)
It is a prime factorization because each base (2,3,5, and 11) is a prime number.
A prime number is one where the only factors of it are 1 and itself.
- factors of 2 = 1 and 2
- factors of 3 = 1 and 3
- factors of 5 = 1 and 5
- factors of 11 = 1 and 11
Instead of saying something like 11^2, we could write 11*11. Similarly, 5^4 could be written as 5*5*5*5. Though it's a good idea to use exponents so you make the prime factorization more compact and save time.
The '3' without an exponent is the same as 3^1. You'll often see that exponent of 1 left out. Again this is to save time.
