Answer:
The experimental probability would be equal to the number of times the event happened over the number of times it was attempted. In this case, the experiment was tried 48 times, and only 6 times did it land on 2. The experimental probability is 6/48, which simplified to 1/8.
It would be 50 times because 15 divided by 3 is 5 and you just add your 0 back and get 50! hope this helps!
For x^2-49
this is a diffarence of two perfect squares. I suggest that this is memorised.
a^2-b^2=(a-b)(a+b)
so x^2-7^2=(x-7)(x+7)
so to solve x^2+x-56 you want to find out what two numbers add to 1 and multiply to make -56
since -56 is negative we know that the two number are difarent signs so that eliminatess answers B and D.
if we try answer C -8+7=-1 so the answer is not C because we want +1 not -1
then we see that 8+(-7)=1 so the answer is A
Answer:
-900
Step-by-step explanation:
=(15)(−3)(−2)(10)(−1)
=(((−45)(−2))(10))(−1)
=(90)(10)(−1)
=(900)(−1)
=−900
