Answer:
p value = 0.039
t = - 2.169
Step-by-step explanation:
Applying the null and alternate hypothesis
using excel worksheet to calculate for ( t and p )
t = -2.169
p = 0.039
from the results obtained
The conclusion is affected by the significance level because : 0.1 < p > 0.01
so when the significance level is = 0.1 the Null hypothesis is rejected and we can say the mean time interval will change while
if the significance level = 0.01 the Null hypothesis is accepted and we can not say the mean time interval has changed because the p -value is greater than 0.01
attached is the excel solution
This is a composite. Another way to write them is f(g(x)). Take the function g(x) and stick it in for x in f(x). Like this:
. But we aren't done cuz there's some simplifying there to do.
and canceling out the 3's we get just a simple x as our answer. The choice is the last one above as your answer.
This can be written as (x+4)(x+4)
Multiply everything in the second parenthesis by the x.
x^2 + 4x
Multiply everything in the second parenthesis by 4.
4x + 16
Add these two equations together.
x^2 + 4x + 4x + 16
Combine like terms.
x^2 + 8x + 16
Hope this helps!
Set up the conversion factor like this:
The inches are in the denominator while the feet are in the numerator in the conversion factor. It's set up this way because the numerators and denominators have to be able to cancel out. In this case, the inches would cancel out, and you would end up with 3/12 feet, which is also 0.25 feet. The turtle walks 0.25 feet per second.
