This is a word problem so translate to math so this is asking 6+(4/2) which is 8
Solution :
Sampling may be defined as the technique of selecting the individual members or the subset of the population to make a statistical inferences and estimates the characteristics of the entire population.
There are several sampling methods. This includes : Systematic sampling, clustered sampling, stratified sampling, quota sampling, judgement sampling, random sampling, convenience sampling and many more.
In the context, the sampling methods for each of the descriptions are :
a). The researcher use computer program to randomly choose a sample of 30 mice of the 1000 mice for using her study
--- Simple Random
b). The researcher chose the 1st 30 mice as she can reach the door to the mouse room
--- Convenience sampling
c). The mice those whose are kept in the cages on 10 various shelves in mouse room. The researcher or the experimenter chose the three mice from each shelve.
---- Stratified sampling
d). Each of the cage have 5 mice and the researcher randomly chooses 6 cages for her study
----- Cluster sampling
e). The researcher generates the list of the identification numbers which has been sorted from the smallest to the largest. The researcher randomly picks 1 mouse form the list and selects every 4 mouse until the researcher has 30 mice.
---- Systematic sampling
Answer: The length of the bottom left side is 14.
To find the length of this side, we need to know the relationship between the different sections when chords cross each other.
The relationship is that if you multiply the 2 parts of each chord together, it will equal the product of the two sides in the other chord.
Our equation can be written as:
7(8) = 4(x)
56 = 4x
14 = x
Answer:
Step-by-step explanation:
Use synthetic division:
The coefficients of 2x^3 - 1 are {2, 0, 0, -1}. Setting up synthetic division, we get:
1 / 2 0 0 -1
2 2 2
---------------------------
2 2 2 1
Note that the remainder is 1. The same result would be obtained through long division.
The quotient is 2x^2 + 2x + 2 with a remainder of 1.
Answer: 1.43 h
Step-by-step explanation:
Velocity is 
is defined as the change in position (displacement) 
of an object in a specific time 
:
Where:
is the car's velocity
is the distance the winner car traveled
is the time
Isolating :
Solving with the given information:
This is the winner's time
