Answer:
250 miles
Step-by-step explanation:
Your formula is d=r(t)
d=distance r=speed t=time
In this equation it is asking you how far will you travel if your speed is 50 miles per hour, and the time is 5 hours.
So, using the equation above insert the known numbers and it should look like this: d=50(5) ( distance is unknown / speed is 50 / time is 5 )
Now you can find the distance. All you do is multiply 50 times 5 which equals 250.
So the correct answer is C. 250 miles
The answer would be 4c^2+8c+3

Answer:
Larger sample size gives less std error and hence test statistic is larger.
Step-by-step explanation:
Given that a newspaper is conducting a statewide survey concerning the race for governor. The newspaper will take a simple random sample of n registered voters and determine X = the number of voters that will vote for the Democratic candidate. Is there evidence that a clear majority of the population will vote for the Democratic candidate

Z 2.314550249 0.731925055
p 0.01 0.233
we find that though p is the same, std error is very small for larger sample size thus making z statistic much bigger. So we get p value less than 0.05 whereas for 120 sample size, std error is large so Z statistic is small thus making p value to accept null hypothesis
