First, you have to find the LCD. The LCD of 4 and 7 is 28, so you rewrite the fraction:
7/28
4/28
Then you add them.
Answer:
-7.2
Step-by-step explanation:
Since -3.2 is the first number, this will be the starting point in the number line.
Since we are subtracting, we are going to go 4 units to the left.
-3.2 - 4 = -7.2
Best of Luck!
Answer:
The answer is Option A: "0.2% is a parameter and 11 is a statistic".
Step-by-step explanation:
The main difference between a statistic and a parameter is that a statistic describes a characteristic from a sample and a parameter describes a characteristic of the entire population.
In this case, 11 is the result of the positive salmonella eggs taken out of a sample of 200 eggs. It is a statistic.
Also, we know that of all eggs shipped (the population), 0.2% has salmonella. This 0.2% is a parameter.
The answer is Option A: "0.2% is a parameter and 11 is a statistic".
150 lower level
200 upper level
Let x = lower level and y = upper level. You can then set up an equation for cost as:
35x + 25y = 10,250
and the equation for total tickets as:
x + y = 350.
Solve using any method.
