The power of a power

The power of a power is related with the multiplication of the exponents. For example:

(2^4)^5=2^{4x5}=2^{20}

In this case

(7^{\frac{1}{2}})^2=7^{\frac{1}{2}\cdot2}

Then, the exponentes 1/2 and 2 are multiplied.

Since

\frac{1}{2}\cdot2=1

Then,

\begin{gathered} (7^{\frac{1}{2}})^2=7^{\frac{1}{2}\cdot2} \\ =7^1=7 \end{gathered}

Then, the answer is 7.

Answer- A. 7

If a person flips a coin and then rolls a six dash sided die​, describe the sample space of possible outcomes using Upper H comm
xenn [34]

Answer:

Sample Space (S) = { (1,H), (1,T), (2,H), (2,T), (3,H), (3,T), (4,H), (4,T), (5,H), (5,T), (6,H), (6,T) }  

Step-by-step explanation:

If a person flips a coin; the possible outcomes of flipping a coin are { Head (H), Tail (T) }

If a person rolls a six dash side die, the possible outcomes of rolling a dice are { 1, 2, 3, 4, 5, 6 }

Now, If a person flips a coin and then rolls a six dash side die;

The Sample Space (S) which is the set of all the possible outcomes of the activities carried out can be described as follows:

DIE                               COIN  →

↓                                      

                                        H                               T          

1                                      (1,H)                             (1,T)

2                                    (2,H)                             (2,T)

3                                    (3,H)                             (3,T)

4                                    (4,H)                             (4,T)

5                                    (5,H)                             (5,T)

6                                    (6,H)                             (6,T)

Sample Space (S) = { (1,H), (1,T), (2,H), (2,T), (3,H), (3,T), (4,H), (4,T), (5,H), (5,T), (6,H), (6,T) }

What is the difference between the following two regression​ equations? ModifyingAbove y with caret equals b 0 plus b 1 xy=b0+b1
Leona [35]

Answer:

A. The first equation is for sample​ data; the second equation is for a population.

Step-by-step explanation:

The first equation is y = b_0 + b_1x , this is the equation for sample data as the intercept (b_0) and the slope parameter(b_1)  both are calculated then we have got this and these values are not taken as given.

The Second equation is y = \beta _0 +\beta _1x , this is the equation for population data as we can't calculate these \beta _0 and \beta _1 as we take these values as given and also we do testing for \beta parameter using t test and it is sure that testing is always done on population data not on sample data.
