Answer:
First number: 20
Second number: 30
Step-by-step explanation:
First#: x
Second#: y
Constraints:
x + y = 50
1/4x + 2/3y = 25
Isolate variable y:
x + y = 50
-1/4 (x + y = 50 )
-1/4x - 1/4y = -12.5
Add equations the two equations to eliminate x:
-1/4x - 1/4y = -12.5
1/4x + 2/3y = 25
_________________
5/12y = 12.5
5y = 150
y = 30
Substitution to find x:
x + y = 50
x + 30 = 50
x = 20
Answer:
the slope is -3/4
Step-by-step explanation:
its always rise over run, thats how i remember it
y=4

Applying probability concepts, it is found that the correct statements are:
- c) pa and pb are not equal
- d) pa is 2/3 and pb is 1/3
-------------------------------------------
- A probability is the number of desired outcomes divided by the number of total outcomes.
The sample space, that is, the possible outcomes for the coin tosses is given next, considering H for heads and T for tails.
H - H
H - T
T - H
T - T
-------------------------------------------
- Considering that there is at least 1 tails, the new sample space is:
H - T
T - H
T - T
- pa: probability of one head, two outcomes with 1 head out of three, thus, pa = 2/3.
- pb: probability that the second is tails, so one outcome(T - T) out of three, thus pb = 1/3.
-------------------------------------------
The correct statements are:
- c) pa and pb are not equal
- d) pa is 2/3 and pb is 1/3
