Answer: Hello mate!
In a fair die all the number have the same probability; 1/6
The probability of getting a 4 is the sides with the number 4 divided by the total amount of numbers in the dice, this is 1 divided by, the probability is 1/6
The probability o getting a number divisible by 3 is the number of numbers that are divisible by 3 divided by the total amount of numbers in the dice:
The numbers divisible by 3 are 3 and 6, and in the dice, there are 6 numbers in total, so the probability is 2/6 = 1/3
Answer:
The researcher should use a sample size of at least 140 children to get a margin of error to be within 2%.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence interval 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
is the margin of error.
95% confidence interval
So 
, z is the value of Z that has a pvalue of 
, so 
.
We have that:
So
The researcher should use a sample size of at least 140 children to get a margin of error to be within 2%.
Answer:
3 miles
Step-by-step explanation:
distance/time = distance/time
3/10 ÷ 1/10 = d ÷ 1
x 
= 
30/10 = d
3 = d
