Complete Question
A biologist reports a confidence interval of (3.5,4.9) when estimating the mean height (in centimeters) of a sample of seedlings. What is the estimated margin of error and the sample mean?
Answer:
The margin of error is 
The sample mean is 
Step-by-step explanation:
from the question we are told that
The upper limit is 
The lower limit is 
Generally the margin of error is mathematically represented as
Generally the sample mean is mathematically evaluated as
=>

Answer:
si =25%*p
rate =term=t
from si= ptr/100
term = rate = 5
Step-by-step explanation:
(_ , _) means (X , Y)
(25 , ) means
X = 25 then you need find the value of Y from the equation .
so the first answer is (25,-3)
..............
( , -8) means
Y = -8 then you need to find the value of X from the equation .
so the second answer is ( 0 , -8 )

Answer:
1 or 3
Step-by-step explanation:
hope this helps:)
Answer:
First step to solving the equation is to subtract 10 on both sides:
10 - 10 + 5x =65 -10
5x = 55
Then, we divide by 5 on both sides!
5x ÷ 5 = 55 ÷ 5
x = 11
Our result is 11, so the answer to the problem is 11
