Irina’s basketball team has a 1 in 6 chance of winning the first-place trophy. she rolled a six-sided number cube repeatedly, assigning her team a number between 1 and 6 to demonstrate the probability that her team would win.

which method did she use to collect her data?

survey
simulation
experiment
observational study

Simulation.

Step-by-step explanation:

Simulation is a process to model random events, when there is lack of theoretical reasoning in such a way that simulated outcomes closely match real-world outcomes. Researchers observe simulated outcomes to gain insight on the real world.

Given: Irina rolled a six-sided number cube repeatedly, assigning her team a number between 1 and 6 to demonstrate the probability that her team would win.  

Here Irina knows and controls the truth.

Thus, the method she use to collect her data is simulation.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
