If he uses the same amount of water each day then that means its constant. So take your amount of given gallons and divide it by the amount of days there are. What's 645.6/7?
Answer:
the answer is 252 degrees
Answer:
Hypothesis
a. If two integers are even
Conclusion
b. then their sum is even
Step-by-step explanation:
We divide the statement into two parts . The first part is true only when the second is also true. The only way we can reject the hypothesis is that the conclusion is false.
In the statement "If two integers are even, then their sum is even" the part "If two integers are even" would be considered true or false on the basis of "then their sum is even" validity. So if the "then their sum is even" (conclusion ) Part is proved then the "If two integers are even" ( hypothesis) is also true.
Hence the hypothesis is
a. If two integers are even
and
Conclusion is
b. then their sum is even
Answer:
a)0.654
b)-0.34
Step-by-step explanation:
a)2 3 4 5 6 7
Standard deviation
Standard deviation
Df = n-1 = 6-1 = 5
Assume α=0.05
So
So, t critical = 2.57
So, t calculated < t critical
b)1 2 2 5 5 7
Standard deviation =
Standard deviation =
Df = n-1 = 6-1 = 5
Assume α=0.05
So,
So, t critical = 2.57
So, t calculated < t critical
Distribute both numbers from the outside of the parenthesis and multiply that by the the number inside the parenthesis. So 1/2(4x+13) means that you have to multiply 1/2 by 4 and 1/2 by 13. 2x+6.5=6(x+7). On the other side, 6(x+7) do the same thing multiply 6 by x and 6 by 7. 2x+6.5=6x+42 Now thats done, move the "like terms" on the same side. So 2x will move to the other side of the equation while 42 will move the other side of the equation. 4x= -35.5 now divide -35.5 by 4 to find x. -8.875 is what x equals. I hope this helps you! You can also check if the x your found was correct.
