1. 25 x 0.39 = $9.75
2. 5.56 + 5.81 = 11.37, 11.37/2 = 5.685
If you sort out the fractions better I can for sure help:)) I just need to know every fraction it’s hard to tell by what you wrote:))
the square and the square root should cancel so your left with only 50xy
Hello!
We have two probabilities we can use; we have 170/400, for our experiment, and 1/2, which is our theoretical probability.
To solve, we just multiply the two probabilities.
=0.2125≈21.3
Therefore, we have about a 21.3% chance of this event occurring.
I hope this helps!
Let a and b be store A and store B, respectively. Then:
3a+b=63
5a+4b=140
So
12a+4b=252
5a+4b=140
7a=112
a=16
b=15
