The value of x in the equation x0.09 = 0.81 is 9

The equation is given as

x0.09 = 0.81

Rewrite the above expression properly

So, we have:

x * 0.09 = 0.81

Divide both sides by 0.09

So, we have:

x = 0.81/0.09

Evaluate

x = 9

Hence, the value of x in the equation x0.09 = 0.81 is 9

we get that the power set of {2, 3, 4, 5} a subset of the power set of {1, 2, 3, 4, 5, 6}.

We are given a power set:

A = {1, 2, 3, 4, 5, 6}

We are also given another power set:

B = {2, 3, 4, 5}

We need to tell if B is a subset of A or not.

We can see that every element of B is a part of A as well.

So, we can say that B is a subset of A.

B ⊂ A

{2, 3, 4, 5} ⊂ {1, 2, 3, 4, 5, 6}

Therefore, we get that the power set of {2, 3, 4, 5} a subset of the power set of {1, 2, 3, 4, 5, 6}.

Answer: 72

Step-by-step explanation: First step that I did was to subtract 12 and 4 to get 8. I then subtracted 3 and 2 to get 1. Then since 8 and 1 are in the parenthesis, I multiplied 8 and 1 to get 8. 8 to the 2nd power then comes out to 64. 64 adding the square root of 64 which is 8 then comes out to 64 plus 8 because the square root of 64 is 8. 64 plus 8 equals 72.

The product of 84.12 and 19.3 will have three decimal places.

Here, we are given a number 84.12. As we can see this number has 2 decimal places. We need to find a number such that when it is multiplied by 84.12, the result has 3 decimal places.

Let us look at each option one by one,

1. 4.22

4.22 has 2 decimal places and hence if we we multiply it by 84.12, it will give us 4 decimal places. Thus, it is not the correct option.

2. 10.51

Again, 10.51 has 2 decimal places and hence if we we multiply it by 84.12, it will give us 4 decimal places. Thus, it is not the correct option.

3. 14.163

14.163 has 3 decimal places and hence if we we multiply it by 84.12, it will give us 5 decimal places. Thus, it is not the correct option.

3. 19.3

19.3 has 1 decimal place and hence if we we multiply it by 84.12, it will give us 2 decimal places. Thus, 19.3 is the correct option.

The value of x in the angles is 20

The angles are given as

4x - 12 and 7x - 28

These angles are same side interior angles

So, we have

4x - 12 + 7x - 28 = 180

Collect the like terms

So, we have

4x + 7x  - 12 - 28 = 180

Evaluate the like terms

So, we have

11x  = 220

Divide both sides by 11

x= 20

Hence, the value of x in the angles is 20

the triangle at the top and the triangle at the bottom are rectangles

we can solve with the Pythagorean theorem.

c² = 10² - 8²

c² = 100 - 64

c² = 36

c = √36

c = 6 cm

c² = 17² - 8²

c² = 289 - 64

c² = 225

c = √225

c = 15 cm

Step-by-step explanation:

The Type I error's computed value is 0.02275 and The Type II error has a computed value of 0.50 based on probability.

What is probability?

(a) Type I error probability if the critical region is defined as x < 11.5 kilograms

[tex]P(Type\ Error)=P\ xbar < 11.5\ when\ mu=12)\\\\[/tex]

[tex]=P(Z < \frac{11.5-12}{\frac{0.5}{\sqrt{4} } } )\\\\=P(Z < -2)\\\\=0.02275[/tex]

The Type I error's computed value is 0.02275.

Observe that there is a 2.275% likelihood of dismissing the null hypothesis if it is true based on the Type I error probability.

(b) β for the case in which the true mean elongation is 11.25 kilograms.

[tex]b= P(Type II Error)\\\\=P(xbar\geq 11.5\ when\ mu_1\ =11.25)[/tex]

[tex]=P(Z \geq \frac{11.5-12}{\frac{0.5}{\sqrt{4} } } )\\\\=P(Z \geq 1)\\\\= 1-P(Z < 1)\\\\=1-0.8413\\\\=0.1587[/tex]

The Type II error's computed value is 0.1587.

Observe that there is a 15.87% possibility of refusing to disprove the null hypothesis when it is untrue based on the Type II error probability.

(c)  β for the case in which the true mean is 11.5 kilograms.

[tex]b= P(Type II Error)\\\\=P(xbar\geq 11.5\ when\ mu_1\ =11.25)[/tex]

[tex]=P(Z \geq \frac{11.5-11.5}{\frac{0.5}{\sqrt{4} } } )\\\\=P(Z \geq 0)\\\\= 1-P(Z < 0)\\\\=1-0.50\\\\=0.50[/tex]

The Type II error has a computed value of 0.50.

Observe that there is a 50% possibility of neglecting to disprove the null hypothesis when it is untrue based on the Type II error probability.
