Answer:
D.) 1/5
Explanation:
Experimental probability is the ratio of the number of successes to the number of trials.
In this case, success is a bulls-eye. Tim had 10 bulls-eyes. The total number of trials is 50. This makes the experimental probability 10/50, or 1/5.
Step-by-step explanation:
If x is the volume of the first tank, and y is the volume of the second tank, then:
x + y = 55
x = 2y + 4
Solve the system of equations using either substitution or elimination. Using substitution:
2y + 4 + y = 55
3y + 4 = 55
3y = 51
y = 17
Solve for x using either equation.
x + 17 = 55
x = 38
The first tank holds 38 gallons, and the second tank holds 17 gallons.
