<span>Experimental Probability is the ratio of the number of times an event occurs to the total number of trials.
Given that </span><span>Cole
rolls a number cube multiple times and records the data in the table below. At the end of the experiment, he counts that he has rolled 190
fours.
From the table, we see that the total number of trials is 1,000 and there are 190 fours.
Therefore, the experimental probability of rolling a four, based on
Cole’s experiment is given by 190 / 1,000 = 0.19 = 0.190 to the nearest thousandth.</span>

8 t ^ 2 + 4 t ^ 2 - 8 4 t
Answer:
All but the one on the bottom left
Answer:
x= 2 and y = -4
Step-by-step explanation:
8x + 3y = 4 ---------------------------------(1)
-7x + 5y = -34 -----------------------------(2)
Multiply through equation (1) by 5 and multiply through equation(2) by 3
40x + 15y = 20 ----------------------------(3)
-21x + 15y =-102----------------------------(4)
Subtract equation (4) from equation (3)
61x = 122
Divide both-side of the equation by 61
61x/61 = 122/61
(At the left-hand side of the equation 61 will cancel-out 61 leaving us with just x, while at the left-hand side of the equation 122 will be divided by 61)
x = 122/61
x=2
Substitute x= 2 into equation (1)
8x + 3y = 4
8(2) + 3y = 4
16 + 3y = 4
Subtract 16 from both-side of the equation
16-16 + 3y = 4-16
3y = -12
Divide both-side of the equation by 3
3y/3 = -12/3
y = -4
x= 2 and y = -4
