Answer:
The data does not provide sufficient evidence to conclude that Kenneth's mean stacking time is less than 8.2 seconds.
Do not reject the null hypothesis because the p-value 0.0401 is greater than the significance level.
Step-by-step explanation:
Null hypothesis (H0): mu = 8.2 seconds
Alternate hypothesis (Ha): mu < 8.2 seconds
Significance level = 0.04
p-value = 0.0401
Using the p-value approach for testing hypothesis, do not reject H0 because the p-value 0.0401 is greater than the significance level 0.04.
There is not sufficient evidence to conclude that Kenneth's mean stacking time is less than 8.2 seconds.
For the first one:
2x + 2 = 3x - 52
2x + 2 + 52 = 3x - 52 + 52
2x + 54 = 3x
2x - 2x + 54 = 3x -2x
54 = x
For the second:
124 + 2x + 4 = 180
124 + 4 + 2x = 180
128 + 2x = 180
128 - 128 + 2x = 180 - 128
2x = 52
2x/2 = 52/2
x = 26
Answer:
Below
Step-by-step explanation:
2x + 5 > -1
Treat the equality sign (ex. < >) as the costumary equal sign (=).
2x + 5 + (-5) > -1 + (-5) ---- -5 will cancel out the 5 on the left
2x/2 > -6/2 ------ divide by 2 to single out the x
x > -3
Remember to draw an open dot. Draw an arrow from -3 to the extreme right.
