Answer:
He lost 5 coconuts.
Step-by-step explanation:
When he divides the number left among 3 and 5 people the remainder is 2 in each case so the number that each person gets must be 15 or a multiple of 15.
So if x is the number left when he reaches home, then:
2 = x mod 3 and
2 = x mod 5
where x = 15 + 2 = 17 or 30 + 2 = 32 or 45 + 2 = 47.
But we also must satisfy 3 = x mod 4
If x = 17:
17 mod 4 = 1 so its not 17.
32 mod 4 = 0 so it's not 32.
47 mod 4 = 3 so x = 47.
Therefore the number he lost = 52 - 47 = 5.
Answer: 8+(x÷3)=−2.

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.
For this case we have that, by definition, the domain of a function is given by all the values for which the function is defined.
Having said that, we have the following function:
It is not defined when the denominator is equal to 0. That is:
Thus, the domain of r (x) is given by all real numbers except 1.
Answer:
all real numbers except 1.
