Answer:
10 hours to drive 500 miles
6 hours to drive 300 miles
Step-by-step explanation:
Hi, to answer this we have to calculate the speed rate first:
Speed = distance /time
Speed = 200 miles / 4 hours = 50 miles per hour
So, to find the time for each number of miles:
Time = distance /speed
For 500 miles:
t = 500/50 = 10 hours
For 300 miles
t = 300/50 =6 hours
So, in conclusion:
It will take 10 hours to him drive 500 miles
It will take 6 hours to him drive 300 miles
Answer:
This would be test of independence because it contain only one sample test
Step-by-step explanation:
Test of independence determine two factors are independent or not
For example
if we do a test of independence
null hypothesis : H 0: Being a cell phone user while driving and receiving a speeding violation are independent events. If the null hypothesis were true, we would expect about 28 people to use cell phones while driving and to receive a speeding violation.
Therefore in the given question Each respondent answer that it might be in "Right Direction " or "Wrong Direction".
So it is a independent test.

Answer:
105 frames
Step-by-step explanation:
Given that:
At 0 seconds, the video had already played 190 frames and there are 25 frames being played per second.
When the time is equal to 
, the number of frames that are already being played is:
= 17 × 5
= 85 frames.
But recall that, the frames had already played 190 frames at 0 seconds, then the number of frames that had already been played when the time is equal to is;
=(190 - 85) frames
= 105 frames
The first set of parentheses is unnecessary, so just drop it.
The second set of parentheses has a negative sign to its left.
To simplify the second set of parentheses, change every sign inside the parentheses. Then combine like terms.

= -x - 4x - 2 - 3
= -5x - 5
