Answer:
(4) x+12=5x-2
Step-by-step explanation:
Substitute x=4 in all the options to check equality
Answer:
The p value would be given by this probability:
Since the p value is higher than the significance level we have enough evidence to FAIL to reject the null hypothesis and then we can conclude that the true mean is not significantly different from 29.1 MPG
Step-by-step explanation:
Information given
represent the sample mean
represent the population standard deviation
sample size
represent the value to verify
represent the significance level
t would represent the statistic
represent the p value
Hypothesis to test
We want to verify if the true mean is equal to 29.1 MPG, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing the info:
The p value would be given by this probability:
![p_v =2* P(z](https://tex.z-dn.net/?f=%20p_v%20%3D2%2A%20P%28z%3C-1.768%29%20%3D0.0771)
Since the p value is higher than the significance level we have enough evidence to FAIL to reject the null hypothesis and then we can conclude that the true mean is not significantly different from 29.1 MPG
Answer:
28
Step-by-step explanation:
4 quarts so 112 quarts is equal to 28 gallons.
Answer:
Step-by-step explanation:
- −2x + 5(x − 2) > 7x − 6
- -2x + 5x - 10 > 7x - 6
- 3x - 7x > - 6 + 10
- -4x > 4
- x < - 1
- x = (-∞, -1)
The graph is all points to the left from -1, where -1 is not included
