35- “4000“ those are the answers
Answer: 6/40 = 3/20
Step-by-step explanation:
The experimental probability is the number of times the desired result was obtained over the number of times the experiment was carried out:
P= Time the event occurs/ Total number of trials
In this case the event we are looking for is rolling a 3 on the number cube. The total number of trials is: 40
because the student rolls the cube 40 times. and the time that he got the number 3 (the times the desired event occurs) is: 6
because he rolls a 3 on the number cube 6 times. Thus our experimental probability to roll a 3 is: P = 6/40
Answer: 0.03 and 0.4
Step-by-step explanation:
3.0 would turn into 3.
3 divided by 100 is 0.03.
20 divided by 50 is 0.4
So, I think that it would be either 0.03 or 0.4
Answer:
-3
Step-by-step explanation:
(x+3)(x-1) - x(x+2)
Foil the first term
First x^2
outer -x
inner 3x
last -3
Add them together
x^2 -x+3x-3 = x^2 +2x-3
x^2 +2x-3 - x(x+2)
Distribute the second term
x^2 +2x-3 -x^2 -2x
Combine like terms
-3
