Answer:
Step-by-step explanation:
The exponent rule that applies to products like this is ...
... (a^b)(a^c) = a^(b+c)
In your problem, this is
... x^(1/3)·x^2 = x^(1/3 +2) = x^(1/3 +6/3) = x^(7/3)
This fractional exponent translates to the root of a power:
... = (x^7)^(1/3)
In typeset form, it is ...
You have already figured correctly that the coefficient is 3·8 = 24.
Answer:
d: 2, 4, -6, 0, -1, -5, 0, 1
The second step is calculate the mean difference
The third step would be calculate the standard deviation for the differences, and we got:
The next step is calculate the statistic given by :
And the correct option would be:
a. t = -0.523
Step-by-step explanation:
We assume the following notation:
x=test value after , y = test value before
x: 34 39 28 33 27 23 35 33
y: 32 35 34 33 28 28 35 32
The system of hypothesis for this case is given by:
Null hypothesis:
Alternative hypothesis:
The first step is calculate the difference and we obtain this:
d: 2, 4, -6, 0, -1, -5, 0, 1
The second step is calculate the mean difference
The third step would be calculate the standard deviation for the differences, and we got:
The next step is calculate the statistic given by :
