Answer:
one solution
Step-by-step explanation:
7x - 3 = 5x + 5 ( subtract 5x from both sides )
2x - 3 = 5 ( add 3 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4
Most of the information's that are required for solving the problem is already given in the question. So it is very important to read the question minutely before going for solving and getting to the desired answer.
Total number of eggs that Mary has = 216
Number of eggs that can fit in each carton = 12
Then
Number of cartons required to completely fill = 216/12
= 18
So 18 cartons are required by Mary to fill all the eggs that she has. I hope the procedure is simple enough for you to understand. You can always use this method for solving similar questions in future without requiring any kind of additional help from anybody.
Answer:
D) 0.78, 0.029
Step-by-step explanation:
Central Limit Theorem:
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean 
and standard deviation 
About 78% of the US, population claims that they visit the dentist at least once a year.
This means that 
Random sample of 200 people:
This means that 
Mean and standard deviation of the sampling distribution:
By the Central Limit Theorem
Mean 
Standard deviation 
So the correct answer is given by option D.
The answer has to be -9 because -9 + -4 is equal to -9 - 4, and that equals -13.
