cean and the mean weight is 550 pounds.37 The Center for Biological Diversity is concerned that this species has been overfished and that the mean weight has decreased. Suppose a random sample of 12 Atlantic bluefin tuna was obtained from commercial fishing boats and weighed. The summary statistics were x 5 535.7 and s 5 37.8. Conduct a hypothesis test to determine whether there is any evidence that the mean weight of Atlantic bluefin tuna is less than 550 pounds.

Convert 3.0x10^10 cm/s to ft/s
Paladinen [302]
The number that is given in the question and that needs to be converted is 
3.0 * (10)^10 cm/s
This can be simplified and written as 30000000000 cm/s. It has to be converted to ft/s.
1 cm = 0.0328084 feet
Then
30000000000 cm = 0.0328084 * 30000000000 ft
                             = 984252000 ft
So
3.0 x (10)^10 cm/s = 984252000 ft/s
I hope the answer has come to your help.

Need help please asp thank you so much

Answer:

x = -1, 3

Step-by-step explanation:

so what you need to do is graph each one because that's what the questions ask. One way for you to check your answer is to set the two equations equal to each other.

-x + 5 = x^2 - 3x + 2

you want to end up with one equation and having the equation equal 0. So add x to both sides to cancel out the x on the left side and then subtract 5 from both sides to cancel out the 5 on the left side.

0 = x^2 - 2x - 3

now you factor

0 = (x - 3) (x + 1)

x = -1, 3
