Answer:
False equation: -2|8 - 6| - 6 = -10
Step-by-step explanation:
-2|8 - 6| - 6 = -12 True or false?
-2 | 2| - 6 = -12 Substract 8 - 6 = 2
-2 × 2 - 6 = -12 |2| = 2 absolute value of 2 is 2
- 4 - 6 = -12 -2 × 2 = -4 ( negative times positive = negative)
-10 = -12 False
2.12+3x=9.45
each juice was about $2.44, so your answer was correct!
Answer:
Step-by-step explanation:
From the information given, we would write the hypothesis.
For the null hypothesis,
H0 : µ = 70
For the null hypothesis,
Ha : µ > 70
This is a right tailed test because of the symbol of greater than.
The decision rule is to reject the null hypothesis if the level of significance is greater than the p value and accept the null hypothesis if the level of significance is lesser than the p value.
Therefore, since the significance level, 0.05 > p value, 0.01635, then we would reject the null hypothesis. There is enough evidence that the mean speed of all cars is greater than the posted speed limit of 70 mph.
