Answer: The probability that at least 4 boys will find one that commutes to school with bicycle is 10% or 0.1 or 1/10
<u>Given:</u>
40% ride bicycle to school
4 boys have to pick 1
Step-by-step explanation:
40% ⇒ 40/100
⇒
= 10 ⇒ 10% or 0.1 or 1/10
Answer:
Cluster Sampling
Step-by-step explanation:
I cant be 100% sure as i am not in statistics, but by definition cluster sampling is a probability sampling technique where researchers divide the population into multiple groups (clusters) for research (in this case its the phone book). Researchers then select random groups (three random pages) with a simple random or systematic random sampling technique for data collection and data analysis(interviews).
so that appears to be what is happening in this scenario.
No there not equivalent <span />
Answer: On factoring out coefficient of variable for (4h-3) we get:

Explanation:
Coefficient of the variable is the number which is multiplying with the variable. Generally coefficient is written before the variable for example: 2 is the coefficient of x in equation (2x+1).
Here in the given equation (4h-3) the coefficient of the variable 'h' is 4.
When we factor out the coefficient of the variable 'h' from the given equation we will get:
