Answer: A.4/25
Step-by-step explanation:
Number of trials that were performed = 50
Number of times a blue balloon was chosen = 22
Number of times a yellow balloon was chosen = 7
Number of times an orange balloon was chosen = 8
Number of times a purple balloon was chosen = 13
The estimated probability of choosing an orange balloon from the bag will be the number of times that an orange balloon was chosen divided by the total number of trials. This will be:
= 8/50
= 4/25
Answer:mass CO2 = (mass AS) - (final mass)
Step-by-step explanation:
Answer:
pentagon have 5 sides, 5 symmetry lines.
So your answer is Option C.
The approximate solution to the given system of equation is (-2.71, 2.14)
<h3>Solving a system of linear equations</h3>
From the question, we are to determine the approximate solution to the given system of linear equations.
The given equations are
y = 0.5x + 3.5
y = -2/3 x+ 1/3
From the given information, we are to show the solutions on a graph
The graph that shows the solution to the given system of equation is shown below.
The solution to the given system is the point of intersection of the lines. The coordinate of the point of intersection of the lines is (-2.71, 2.14). That is, x = -2.71, y = 2.14.
Hence, the approximate solution to the given system of equation is (-2.71, 2.14)

Answer:
x=1.818minutes
Step-by-step explanation:
3/60 miles per minute for walk
8/60 miles per minute for run
0.05x + 0.1333y=1
x+y=10
x=y-10
0.05(y-10) + 0.133333y = 1
0.05y-0.5+0.133333y=1
0.18333y=1.5
y=8.18minutes
x=10-8.18
x=1.818minutes
