Answer:
78.5
Step-by-step explanation:
A=πr^2 is the formula. Since you're using pi as 3.14, 3.14 times 5^2 is 78.5 (5^2 is 25 because 5x5=25)
Well, we need to divide $36.25 by 12.5. This will give us the per gallon price. So 36.25/12.5=2.90.
So regular gasoline is $2.90 a gallon
So, now we know this, if we add 14¢ to 2.90, we get $3.04. Now, we multiply 3.04 by 12.5=38. So, 12 and a half gallons of premium gas costs $38
Answer:
A. On average the blood pressure levels before the stress reduction program were significantly higher than the systolic blood pressure levels after the stress reduction program, at 95% confidence level
Step-by-step explanation:
The confidence interval parameters is intended to detect if the new stress reduction program will lower the systolic blood pressure levels of employees
The difference between the the mean systolic blood pressure levels taken = The before systolic pressure - The after systolic blood pressure
The 95% confidence interval obtained = (5.6, 10.2)
Therefore, given that the values of the difference between the means are both positive, then there a difference as the confidence interval does not include zero (0), and at the 95% confidence level, the average systolic blood pressure levels before the stress reduction program are higher than the average systolic blood pressure levels after the program
Answer: Translate triangle ABC so that point B lies on point D to confirm ∠B ≅ ∠D.
Step-by-step explanation: Since we already know that angle A is congruent to itself by the reflexive property, all we need is another pair of corresponding angles to be congruent according to the AA (angle-angle) similarity postulate. This postulate states that; If two corresponding angles of two or more triangles are congruent, the triangles are similar. So when we translate triangle ABC so that point ∠B lies on ∠D, we prove that these two angles are congruent.
I also got it right on the test. So... yeah.
hope this helps dood.
It mostly depends on what operation you are doing.
