Answer:
Stratified design with color of paper as the blocks
Step-by-step explanation:
The experimental design that this question uses is the stratified design with color of paper as the blocks
A stratified design is one where the population has been divided into strata that are homogeneous. A good number of participants would then be picked for each of the stratum. The homogeneous strata are also known as the blocks and here in this question we have color of paper as the block here.
The students are of different school levels, elementary, high school and middle school. Each of these levels have 100 students. The students in each levels are halved and each half is randomly assigned information on either a white paper or a blue paper.
Answer:
C
Step-by-step explanation:
Given
m + 5 = 17 ( subtract 5 from both sides )
m = 12 ( multiply both sides by 3 to clear the fraction )
2m = 36 ( divide both sides by 2 )
m = 18 → C
Answer:
x=35.35
Step-by-step explanation:
If you multiply 
by 10.1 that will cancel out the 10.1s, then since you multiplies one side of the equation by something you have to multiply the other too. So 3.5*10.1 = 35.35. Then since the 10.1s canceled out this leaves us with x=35.35. Let me know if you need any more help.
We know that
The Sun makes a complete circle in the sky approximately every 24 hours, while the stars make a
complete circle in the sky in 4 minutes less time, or 23 hours and 56 minutes
<span>Sirius is a star
so
</span><span>If Sirius rises at 8:00 pm tonight
then
tomorrow </span>will it rise at ------> 8:00 pm -4 minutes----> 7:56 pm
the answer is
7:56 pm
For this case we have the following expression:
By definition of properties of powers and roots we have to:
![a ^ {\frac {m} {n}} = \sqrt [n] {a ^ m}](https://tex.z-dn.net/?f=a%20%5E%20%7B%5Cfrac%20%7Bm%7D%20%7Bn%7D%7D%20%3D%20%5Csqrt%20%5Bn%5D%20%7Ba%20%5E%20m%7D)
Then, we can rewrite the expression as:
![\sqrt [8] {4 ^ 3}](https://tex.z-dn.net/?f=%5Csqrt%20%5B8%5D%20%7B4%20%5E%203%7D)
Answer:
![4 ^ {\frac {3} {8}} = \sqrt [8] {4 ^ 3}](https://tex.z-dn.net/?f=4%20%5E%20%7B%5Cfrac%20%7B3%7D%20%7B8%7D%7D%20%3D%20%5Csqrt%20%5B8%5D%20%7B4%20%5E%203%7D)
