Answer:
The fastest runner is Katie
Step-by-step explanation:
In order to determine this, we must first put them all in the same terms. For the purpose of this, we will put them all in feet per second.
Katie
14 feet/1 second = 14 ft per second
Zach
576 feet/46 seconds = 12.52 ft per second
Tony
1 mile/533 seconds = 5280 feet/533 seconds = 9.91 ft per second
Will
827 feet/1 minute = 827 feet/60 seconds = 13.78 ft per second.
So we know that the fastest is Katie.
Answer:
Part 1
its asking you to find the slope of the given lines by using the points that they have plotted on the lines
first you need to figure out what the points are, then insert it into the formula
the formula for this would be 
Part 2:
its asking you to find the slope using the points that are written in each box
again, just substitute it into the formula
the formula for this would be
Answer:
r = - 
Step-by-step explanation:
Given that r varies inversely as t , then the equation relating them is
r = 
← k is the constant of variation
To find k use the condition t = - 6 when r = - 2, then
- 2 = 
( multiply both sides by - 6 )
12 = k, thus
r = 
← equation of variation
when t = - 7, then
r = 
= -
Answer: C should be correct!
Hope it helps!
Answer:
it would remain unchanged
Step-by-step explanation:
It asks us that If the confidence coefficient is increased from 0.95 to 0.99, the standard error of the mean will
in this case it would remain unchanged, because standard error of the mean is = sd / (n ^ 1/2), that is, it does not intervene in the calculation, therefore it does not change
