members of the wide waters club pay 105 dollars per summer season, plus 9.50 each time they rent a boat. Nonmembers must pay 14.
WITCHER [35]
When handling problems of this nature make sure you setup the equations. 
x = number of times they rent a boat. 

Members 
Cost = 105 + 9.50x
Non members because members don't have to pay the 105 we leave it out. 
Cost = 14.75x 

so now to determin when cost would be equal we set the two equations = to each other

105 + 9.50x = 14.75x 

now solve for x 

105 = 5.25x
 
20 = x 

so they would have to rent 20 times to equal each other.

________ is a fundamental difference between the t statistic and a z-score
chubhunter [2.5K]

Answer:

Step-by-step explanation:

- The Z-score allows you to decide if your sample is different from the population mean. In order to use z, you must know four things:

  • The population mean.
  • The population standard deviation.
  • The sample mean.
  • The sample size.

- Usually in stats, you don’t know anything about a population, so instead of a Z score you use a T-Test with a T Statistic.

- The major difference between using a Z score and a T statistic is that you have to estimate the population standard deviation. The T test is also used if you have a small sample size (less than 30).

box A has 4 marbles.box A has 5% of the marbles.what is the total amount of marbles in all four boxes
laila [671]
Box A is 4. 4 is 5% of the total boxes.
5% = 1/20, so multiply whatever number that's 5% of the total by 20 to get the total.
4 x 20 = 80.
There are 80 marbles total.
Hope this helps!
