Normally you will see these expressions in reverse order with descending powers of the variable.
-4y^4 + y^3 - y^2 + 11y + 9
So you start with the high order terms and end with a constant.
Answer:
95% confidence interval will be narrower.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 50
95% confidence interval for average alcohol content:
a) 90% confidence interval
- If we calculate a 90% confidence interval, then the confidence interval become narrower because we decreased the confidence percentage.
- This would decrease the margin of error.
- Hence, the confidence interval become narrower.
Answer:
1. (x - 5), (x + 1)
2. (x + 5), (x -2)
Step-by-step explanation:
1. x^2 - 4x -5
Find two numbers that both multiple to -5 and add to -4 (-5 and 1)
(x - 5), (x + 1)
2. x^2 - 3x - 10
--same concept for these question
What two numbers multiple to equal -10 and add to equal 3?
5 and -2
(x + 5), (x - 2)
The correct answer is:
B: 48
Hope this helped!
If you're finding the future value: P=35,000(1-.1/1)^1. this is assuming you want to know the value of it after one year. if you want it to be more years, like two : P=35,000(1-.1/2)^2. When entered into the calculator enter it like so : 35,000(1-(.1/1))^1. when that's done you end up with $31,500. that's the machine's worth. it lost 3,500. 35,000-31500.
