Answer:
1 5/12 miles.
Step-by-step explanation:
That is 2/3 + 3/4
= 8/12 + 9/12
= 17/12
= 1 5/12 miles.
The mean decreases, think about it, if every single value in a data set was decreased by the same number, the average would also go down by the same number
The median would also go down, because the value in the middle of the data set would now be smaller than before
The mode would also decrease, because the value that showed up the most in the data set has now also been decreased
The range, however, stays the same. If the lowest value in a data set was 3 and the highest was 10 and you subtracted 2 from each value in the data set, you would have the lowest at 1 and the highest at 8. But, 10-3 still equals 8-1, so the range is unchanged
It should be b let me know if im right
To get a close estimate, we can round 49 up to 50 and 311 down to 300, obtaining an estimate of 50/300 = 1/6, or 0.1666... as a repeating decimal. That decimal approximation is a little less than one hundredth away from the actual decimal approximation of ≈ 0.1576
Answer:
The estimate is 
Step-by-step explanation:
From the question we are told that
The sample size is n = 522
The sample proportion of students would like to talk about school is 
Given that the confidence level is 90 % then the level of significance can be mathematically evaluated as
Next we obtain the critical value of 
from the normal distribution table, the value is
Generally the margin of error can be mathematically represented as
=> 
=> 
Generally the estimate the proportion of all teenagers who want more family discussions about school at 90% confidence level is
substituting values
