Answer:The correct answer is A, 14%.
Step-by-step explanation:
All you have to do is take the 30% chance of you HAVING to stop at the first light and find the chance that you won't have to stop at the first light, which is 70%, or .7. Then you take the chance of having to stop at the second light which is 80%, and find the probability of NOT having to stop there, which is 20%, or .2. Then you multiply the probabilities of not having to stop, which equals to .14.
Answer:
Step-by-step explanation:
In a survey of first graders, their mean height was 51.6 inches with a standard deviation of 3.6 inches. Assuming the heights are normally distributed, what height represents the first quartile of these students?
54.03 inches
48.57 inches
48.00 inches
49.17 inches
17 quarts is greater. 4 gallons is equal to 16 quarts, right?
So 17 quarts would be greater than 4 gallons or 4.25 gallons
17 QUARTS IS GREATER.
Answer:
Step-by-step explanation:
The given system of linear equations is:
We have to solve the equations for the values of .
Let us use elimination method in which we eliminate one of the variables from the two variables.
For this, let us multiply the first equation by and second equation by
Now, the equations become:
Now, let us add (1) and (2):
Using the equation:
Putting value of :
So, the answer to the system of linear equations is:
