Answer:
Fail to reject H0 in all three cases
Step-by-step explanation:
Given that a certain pen has been designed so that true average writing lifetime under controlled conditions (involving the use of a writing machine) is at least 10 hr.
![H_0: \bar x=10\\H_a \bar x >10](https://tex.z-dn.net/?f=H_0%3A%20%5Cbar%20x%3D10%5C%5CH_a%20%5Cbar%20x%20%3E10)
(Right tailed test at 1% sign level)
n = 19
a) t =-2.5 , df = 18
p = 0.01154
p >1% hence Fail to reject H0
b) t = −1.83
p = 0.041931
p >1% Fail to reject H0
c) t = 0.57
p = 0.287>1% Fail to reject H0
<u>Given</u>:
The given inequality is ![x>4](https://tex.z-dn.net/?f=x%3E4)
We need to determine the graph that fits the inequality.
<u>Graph of the inequality:</u>
The inequality means that x is greater than 4. This means that the end value 4 is not included.
To graph the inequality " > " a dashed line is used.
The inequality does not contain any y - value in it.
Hence, it has only one vertical line at
and is shaded for all values of x greater than 4.
Therefore, the graph that fits the inequality
is a vertical dashed line, shaded to the right of the line.
Thus, Option d is the correct answer.
What? Can you be more specific? I'm very confused about what you want
The answer to 0>-5x-6x is x>0 if you are solving for x.
Answer:
5
Step-by-step explanation:
Each triangle is a myriad of both |, ||, and |||.
Because BE = || and FE = ||| then BF = |
CD = 10 but thats equal to 2 | meaning that 1 | is 5.
