Answer:
f she walks for 30 minutes, that means she was traveling at about 280 feet per minute (8,400÷30=280), or about 16,800 feet per hour
Step-by-step explanation:
Answer: 1.467
Step-by-step explanation:
Formula of Margin of Error for (n<30):-
Given : Sample size : n= 22
Level of confidence = 0.90
Significance level : 
By using the t-distribution table ,
Critical value : 
Standard deviation: 
Then, we have
Hence, the margin of error for the confidence interval for the population mean with a 90% confidence level =1.467
Answer:
The fossil is 1860 years old.
Step-by-step explanation:
The equation for the amount of fossil has the following format:
In which Q(t) is the amount after t years, Q(0) is the initial amount and r is the rate of change.
Half-life of c-14 is 5730 years.
This means that 
So
So
How old is the fossil?
This is t for which
So
The fossil is 1860 years old.
<h2>
Coordinate Pairs</h2>
Coordinate pairs are organized like (x,y).
- x tells us the location of the point in relation to the x-axis, the axis that is horizontal.
- y tells us the location of the point in relation to the y-axis, the axis that is vertical.
To determine a coordinate pair, we can determine each coordinate individually, then put them together.
<h2>Solving the Question</h2>
Notice how the red point sits on the very edge of the graph.
When we look at the x-axis, we can see that it occurs at the number 0 on the x-axis. In other words, the red point occurs when x=0.
When we look at the y-axis, we can see that it lines up with the number 2. In other words, the red point occurs when y=2.
Therefore, when we put the two coordinates together like (x,y), we get (0,2).
<h2>Answer</h2>
(0,2)
If the 2q is raised to the second power the answer is 2q^2+7q+3
