The first graphed rational number is at the middle of -2 and -1, thus the number represented is
The second graphed number is five out of six places from from 0 to 1, thus the number graphed is
The difference between the two numbers can be represented as
or
To find the difference,

Answer:
X=60
Step-by-step explanation:
Sum of the Quadrilateral interior angles:360
360-70-130-100=60
Answer:
0.47 and 11.53
Step-by-step explanation:
h = 60t − 5t²
27 = 60t − 5t²
5t² − 60t + 27 = 0
Quadratic formula:
x = [ -b ± √(b² − 4ac) ] / 2a
t = [ -(-60) ± √((-60)² − 4(5)(27)) ] / 2(5)
t = (60 ± √3060) / 10
t = 0.47 or 11.53
Answer:
The value of the test statistic is 
Step-by-step explanation:
Our test statistic is:
In which X is the sample mean, 
is the expected value, 
is the standard deviation and n is the size of the sample.
The level of ozone normally found is 7.5 parts/million (ppm).
This means that 
The mean of 24 samples is 7.8 ppm with a standard deviation of 0.7.
This means that 
Test Statistic:
The value of the test statistic is
The tay would move to the left because that is a less than sign . positive goes to the right and negative goes to the left . thing of the less sign like a L bc it looks like one .
