Answer:
V≈904.78in³
Step-by-step explanation:
They're called equivalent expressions
SOLUTION:
Case: Hypothesis testing
Step 1: Null and Alternative hypotheses

Step 2: T-test analysis

Step 3: t-test with the significance level

Step 4: Comparing

So tail to reject the null hypothesis. There is enough evidence at a 0.05 level of significance to claim that the mean spent is greater than P127.50.
Final answer:
Yes, there is evidence sufficient to conclude that the mean amount spent is greater than P127.50 per month at a 0.05 level of significance.
The answer is A) x=0.3
Step-by-step explanation:
Move all terms containing xx to the left side of the equation.
14x−15.4=−11.2
Move all terms not containing x to the right side of the equation.
14x=4.214x=4.2
Divide each term by 14 and simplify
x=0.3
