Set up two equations:
1st: P (for Price family) + J (for Jenkins family) = 45 hours
2nd: 20P + 35J = 1200 liters
Rewrite the first equation as P = 45 – J
Replace P in the second equation:
20(45-J) + 35J = 1200
Simplify:
900 -20J + 35J = 1200
900 +15J = 1200
Subtract 900 from both sides:
15J = 300
Divide both sides by 15:
J = 300/15
J = 20
Jenkins used theirs for 20 hours
Price used theirs for 45-20 = 25 hours.
To get x intercept：
let y=0，x➖12=0，x=12
so x intercept point （12，0）
To get y intercept：
let x=0，3y➖12=0，y=4
so y intercept point （0，4）
Answer:
3/4
Step-by-step explanation:
Due it having a ratio of .75 instead of the .6875 of the other answers.
Answer:
The answer is "No, There are more than two possible outcomes on each trial of the experiment
".
Step-by-step explanation:
When various ice cream products are known. This might surpass 2 brands or more. Thus the number of different results varies considerably.
BINOMIAL DISTRIBUTION:
An investigation with a set set of individual tests, each only with two possible results.
Four conditions are met by the binomial experiment
- The set of indicators is fixed.
- Each attempt is autonomous.
- 2 potential results exist only.
- In each and every test, the probability of each outcome remains unchanged.
A and D are correct. If u don't know why look up the definitions of the triangles
