We have been given that Y and Z are points on the number line. The length of segment YZ is 9 units and Y lies at -12. We are asked to find the location of point Z.
Since Y and Z are located on number line, so Z can be either on left side of Y or on right side of Y.
When Z is on left side of Y, then we can set an equation as:
Therefore, the location of Z will be .
When Z is on right side of Y, then we can set an equation as:
Therefore, the location of Z will be .
Answer:
Step-by-step explanation:
Given
Peter hits
Mary hits
Required
The probability that Mary wins
From the question, we understand that Peter throws the first.
If Mary is to win, then Peter has to lose his throw
Using the complement rule, the probability that Peter misses is:
So, the probability that Mary wins is:
This gives:
Answer:
Step-by-step explanation:
Given:
A car starts with a dull tank of gas
1/7 of the gas has been used around the city.
With the rest of the gas in the car, the car can travel to and from Ottawa three times.
Question asked:
What fractions of a tank of gas does each complete trip to Ottawa use?
Solution:
Fuel used around the city =
Remaining fuel after driving around the city = 1 -
=
According to question:
As from the rest of the gas in the car that is , the car can complete 3 trip to Ottawa which means,
By unitary method:
The car can complete 3 trip by using = tank of gas.
The car can complete 1 trip by using =
=
=
= tank of gas
Thus, tank of gas used for each complete trip to Ottawa.
