for 49 df and t=1.7986 ,p value can be obtained from software
p value=0.0391
Answer:
F (4h>18)
How To Do It:
She's walking at a rate of 4 miles per hour. Which means that you would be multiplying 4 by the amount of hours Liang walks(4h). The next part of the inequality is the sign and the other value. To get this from the equation we see that it says she must walk at least 18 miles. Meaning that the 4h will always be greater than the 18 that is on the other side.
Answer:
x > 5

x > 5
Answer:
Distance:
units
Step-by-step explanation:
The distance formula is
where:
is the distance between points
and 
are the coordinates of the first point
are the coordinates of the second point
We are given that:
To determine the value of our distance,
, we plug in our given information into the formula and solve for






Therefore, the distance between
and
is
units.
