Simplify the quotient 4.5 x 10^3/9 x 10^7 . Write your answer in scientific notation. Show your work.
astra-53 [7]
4.5*10^3/9*10^7=4.5/9*10^3*10^7=0.5*10^3*10^7. a^b*a^c=a^(b+c), so 10^3*10^7=10^(3+7)=10^10. 0.5*10^10=5*10^9, since we want to write in scientific notation where the leading number is bigger than one and smaller than 10.

To rent a jet ski at Sam’s costs $25 plus $3 per hour. At Claire’s, it costs $7 plus $6 per hour. At how many hours will the ren
skad [1K]

Answer:

 The number of hours that the cost of renting a ski jet will become equal in both shops is 6(hours)

Step-by-step explanation:

  Extracting the key information from the question:-

*** Renting a jet ski at Sam's establishment costs $25 and additional $3 per hour.

*** Again, it costs $7 and additional $6 per hour to rent a jet ski at Claire's establishment.

*** We are required to find out the number of hours that the rental cost of jet ski at both shops will be the same.

  What we are basically required to do is to find that number of hours that you can rent a jet ski and you wouldn't need to worry about the shop that renting it's jet ski will be more affordable in because the cost will be the same in both establishment when renting the jet ski at a particular number of hours.

    For example, in that number of hours, the cost in Sam's shop and Claire's shop will now both be say, $50.

   Since it costs a down payment of $25 plus additional $3 for each hour we make use of the jet ski at Sam's establishment, then the cost of renting a jet ski at Sam's shop for that number of hours that the cost will become equal in both shops is:

  =  25  +  3x

 Again, we are informed that it costs $7 down payment and additional $6 per hour that a jet ski from Claire's establishment will b rented and used. Then the cost of renting a jet ski at Claire's establishment for that number of hours that the cost will become equal in both shops is:

   

       = 7 + 6x

 Since at this unknown number of hours (x hours) the cost of renting a jet ski at Sam's shop will be equal to the cost of renting a jet ski at Claire's establishment, then marrying the equations, we will have:-

25 + 3x = 7 + 6x

We now pair like terms

6x - 3x  = 25 - 7

   3x  =  18

    x  = 18/3

    x  = 6

  Therefore, that number of  hours that the cost of renting a jet ski will become equal in both Sam's and Claire's establishment is 6 hours.

A botanist collected one leaf at random from each of 10 randomly selected mature maple trees of the same species. The mean and t
Zarrin [17]

Answer:

One sample t-test for population mean would be the most appropriate method.

Step-by-step explanation:

Following is the data which botanist collected and can use:

  • Sample mean
  • Sample Standard Deviation
  • Sample size (Which is 10)
  • Distribution is normal

We have to find the best approach to construct the confidence interval for one-sample population mean. Two tests are used for constructing the confidence interval for one-sample population mean. These are:

  • One-sample z test for population mean
  • One-sample t test for population mean

One sample z test is used when the distribution is normal and the population standard deviation is known to us. One sample t test is used when the distribution is normal, population standard deviation is unknown and sample standard deviation is known.

Considering the data botanist collected, One-sample t test would be the most appropriate method as we have all the required data for this test. Using any other test will result in flawed intervals and hence flawed conclusions.

Therefore, One-sample t-test for population mean would be the most appropriate method.
