This is your answer One pound of meat costs 3.50$. If the total is 244$, how many pounds of meat have you bought?
Twice (2 times) the difference (subtraction) of a number (y) and 7 equals 3.
2*(y-7) = 3
hope this helps :)
As a formula, you're saying 4*(n-7)=32
This solves to n-7 = 8, so n=15
Answer:
Yes, I can reject the null hypothesis with 95% confidence.
Step-by-step explanation:
Critical value t(63) = 1.99
p-value = 0.03
Confidence level (C) = 95% = 0.95
Significance level = 1 - C = 1 - 0.95 = 0.05
Conclusion:
Reject the null hypothesis because the p-value 0.03 is less than the significance level 0.05.
3p²q - 6 pq²
3pq (p - 2q )
I think this is the solution
