88 degrees because the two figures are congruent.
The first one it just makes sense.
Answer:
2.33
Step-by-step explanation:
We shall use the z distribution because we know the population standard deviation.
The margin of error formula is given by:
The z-value for 98% confidence interval is 2.326.
The sample size is n=25.
The population standard deviation is is
We substitute the values into the formula to get:
Evaluate square root:
Simplify:
I think the segment has two end point instead of one
If you would like to write 45 minutes to 1 hour in the simplest form, you can do this using the following step:
1 hour = 60 minutes
45 minutes : 60 minutes = 45 : 60 = 3 : 4 (divide both numbers by 15)
The correct result would be 3 : 4.
