4. one solution is (1, 3)
5. (1, -1)
7. -5 = x + 3
x = -5 - 3
x = -8
8. z - 4 = -8
z = -8 + 4
z = -4
Answer:
16 1/3 lbs
Step-by-step explanation:
We can write a ratio to solve
7 lbs x lbs
-------------- = -------------
3 loaves 7 loaves
Using cross products
7 * 7 = 3x
49 = 3x
Divide each side by 3
49/3 = 3x/3
16 1/3 lbs
The outcome for the flip is 2.
Probability:
Probability refer the possibility of the event required.
The probability formula is defined as the possibility of an event to happen is equal to the ratio of the number of favorable outcomes and the total number of outcomes.
Given,
There are 4 coins.
You get a dollar for every head. all four coins are flipped.
To find the outcome of the flips.
The possible outcomes from the initial flip are:
"4 heads" x 1
"3 heads" x 4
"2 heads" x 6
"1 heads" x 4
"0 heads" x 1
This gives an expected return of
=> (4 + 12 + 12 + 4 + 0)/16 = 2
So, the outcome is 2.
Either if you keep it then you have 2 as outcome of the flips, otherwise if you reflip the coins then you will get the same probability for it also.

Answer:
135
Step-by-step explanation:
Given that :
Total score obtained by Peter, Jan and Maxim = 269
Let :
Peter's score = x
Jan's score = y
Maxim's score = z
x + y + z = 269
x > (y + z)
For x to be greater Than y + z ;
Then x > (269 / 2) ; x > 134.5
The least possible x score is 135
Hence, Peter's least possible score is 135.
