Answer:
The answer is C
Step-by-step explanation:
Straight angles means a line which straight and has no turning.
Answer:
The margin of error is of 0.3012, and it means that we should be 99% confident that the population mean would be within 0.3012 of the sample mean.
Step-by-step explanation:
Margin of error

In which
is the standard deviation and n is the size of the sample.
Standard deviation of 1.3
This means that 
She surveys 124 families
This means that 
Margin of error and meaning:



The margin of error is of 0.3012, and it means that we should be 99% confident that the population mean would be within 0.3012 of the sample mean.
The small plane has the following parameters
Distance = 1200 miles
Speed = 300miles/hour
time = ?

If a Boeing 747 leaves 2 hours later, the total time becomes 4hours + 2 hours = 6 hours
Considering the distance of the small plane after 6 hours, we have

So the total distance = 1800 miles
Hence the speed of the Boeing 747 will be


The average speed of the Boeing 747 is 900 miles/ hour
Answer:
1. 1 3/5
2. 3/12 or 1/4
and I think the third slide is the same picture of the first slide picture. (sorry if wrong)
Answer: 2/3x-y=19/3
Step-by-step explanation:
Points are useless since we already know the point slope form and we can just simply that
y+1=2/3(x-8)
y+1=2/3x-16/3
y=2/3x-19/3
2/3x-y=19/3
