Let, the total number of students in school that ride the bike to school be "x"
Now,
Using ratio and proportion, we get,
So, out of 800 students, 125 ride their bike to school.
Answer:a small sample size
Step-by-step explanation:
From the information given in the question, we are informed that Sandra developed a program that was designed to increase reading comprehension scores in 6th graders and she then randomly selects three students and has them participate in her program.
After comparing the mean score from the students who completed her program to three students who did not participate in the program, she finds no significant difference between their mean scores, it should be noted that the reason for this will be because the sample size is small.
If a large sample size was used, this could have been different as thsi could result in a significant difference between their mean scores.
Answer:
(a)10 Outcomes
(b)
Step-by-step explanation:
An urn contains two blue balls (denoted 
) and three white balls (denoted 
).
In the selection, a ball is picked and replaced.
The possible outcomes of the experiment are:
(a)If the first ball drawn is blue. the outcomes are:
There are 10 outcomes if the first ball drawn is blue.
Probability that the first ball drawn is blue
Step-by-step explanation:
3 ( p + 4 ) = 48
3p + 12 = 48
3p = 48 - 12
3p = 36
p = 36 ÷ 3
p = 12...
