All because -2.22 is a real number, it’s a rational number because it can stop and a integer because it’s negative
Answer:
D) (3.67, 4.73)
Step-by-step explanation:
Confidence Interval for the true average number of homes that a person owns in his or her lifetimecan be calculated using M±ME where
- M is the average number of home owned (4.2)
- ME is the margin of error from the mean
And margin of error (ME) can be calculated as
ME=
where
- z is the corresponding statistic in the given confidence level(1.96)
- s is the standard deviation of the sample(2.1)
- N is the sample size (60)
Putting the numbers we get ME=
≈0.53
Then the 95% confidence interval is 4.2±0.53 or (3.67, 4.73)
9.81 or 98.1 pretty sure it's the first one
Answer:
15
Step-by-step explanation:
because here we go.
125|_1,875___
1rst we try to put 125 in 1 we can't so 1-0=1
2ncd we bring down the 8 to make 18 125 still can't go into so 18-0=0
Next 3rd we bring down 7 to make 187
125 can go into that 1 time so 187-125=62
5 th bring down the 5 to make 625
Lastly we do 625 divided by 125 or 125 x ? to get into 625 and we get a 5 so 15.
what it should look like is 1 above 7 and 5 above 5 like.
1 5
-----------=15
1, 8 7 5
Hope this helps have a great day:)
