Answer:
x= 116/17
Step-by-step explanation:
5x+192−321+13=−12x
Step 1: Simplify both sides of the equation.
5x+192−321+13=−12x
5x+192+−321+13=−12x
(5x)+(192+−321+13)=−12x(Combine Like Terms)
5x+−116=−12x
5x−116=−12x
Step 2: Add 12x to both sides.
5x−116+12x=−12x+12x
17x−116=0
Step 3: Add 116 to both sides.
17x−116+116=0+116
17x=116
Step 4: Divide both sides by 17.
17x/17=116/17
x = 116/17
Answer:
z=0.5084
p=0.2809
Step-by-step explanation:
Since number of tires tested for breaking distance is enough (>30), the standardized test statistic is calculated by the formula:
z=
where
- X is the mean breaking distance in the sample (78)
- M is the mean breaking distance (75)
- s is the standard deviation (5.9)
- N is the sample size
Putting the numbers in the formula:
z=
=0.5084 and corresponding p value is:
p=0.28
