Answer:
One can conclude that this sample is obtained through a simple random sampling technique.
Step-by-step explanation:
With a simple random sampling, each population participant has an equal chance of being selected. This sampling method is the best sampling technique when compared with other random sampling methods like the Stratified Random Sampling and Double-stage Random Sampling. The reason is that it gives equal chance to every sample to be chosen by eliminating sample bias.
Log(10) u = 3/2 log(10) 4
u = 8
Step-by-step explanation:
log(10) u = log(10) 4^(3/2)
or
u = 4^(3/2)
= [sqrt(4)]^3
= (2)^3

I need to find x based off of the models
Answer:
2. 9x - 4= 12x - 55
9x - 12x = -55+4
-3x = -51
x = 17
3. 7x +29 = 11x - 31
7x - 11x = -31-29
-4x = -60

Answer:
The product of sin 30° and sin 60° is the same as the the product of cos 30° and cos 60°.
The product of sin 30° and sin 60° is same as the product of cos 30° and cos60°.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
We know that the sine function is a ratio of opposite side and hypotenuse.
The cosine function is a ratio of Adjacent side and hypotenuse.
Let us find the product of sin 30° and sin 60°
=sin 30°.sin 60°
=1/2.√3/2
=√3/4
Now we know that cos 60° is 1/2 and cos 30° is √3/2
Product cos 60° and cos 30°
cos 30°.cos 60°=1/2.√3/2
=√3/4
Hence, the product of sin 30° and sin 60° is same as the product of cos 30° and cos60°.

Conjugate of √a is √a. So, conjugate of √6 is √6. Multiplying √6 with both numerator and denominator.[tex] \to \dfrac{2 - \sqrt{3} }{ \sqrt{6} } \times \dfrac{ \sqrt{6} }{ \sqrt{6} } [/tex]

Answer:
[tex]x=2[/tex]
Step-by-step explanation:
Since the scale is in equilibrium, both sides must be equal. Therefore, we have the following equation:
[tex][\text{Left Side} ]3x+3=[\text{Right Side}]9[/tex]
Solving for [tex]x[/tex]:
[tex]3x+3=9,\\3x=6,\\x=\boxed{2}[/tex]
Answer:x=2
Step-by-step explanation: try to first set up an equation. First we can see the scale is balanced so we know each side is equal to each other. You have 3 x boxes and 3 circles so our first side will be 3x+3. Now let’s move onto the second side. It has 9 circles so 3x+3=9. Now let’s solve!
Subtract 3
3x=6
Now divide by 3
X=2
