Answer:
B. x =1 , y = -5
Step-by-step explanation:
So, what we can do is to simply plug in all of the equations and see which one fits. Equation: x - y = 6
A. x =1 , y = -6
1 -(-6) = 6
1 + 6 = 7
A would be incorrect.
B. x = 1, y = -5
1 - (-5) = 6
1 + 5 = 6
Therefore, B would be correct.
Answer:100%. Probability
Step-by-step explanation:
Emily = aa
Man = AA
After crossing the two, the result wI'll be Aa, Aa, Aa, Aa
Since every result has a carrier(a) in it, makes it 100% probability.
77% of the school want electronic newsletters, so 23% of the school want physical paper newsletters.
77% of 650 is 500.5.
23% of 650 is 149.5.
650/100 = 6.5
6.5x77 = 500.5
6.5x23 = 149.5
It's best to round that figure up to 150 as there will not be a parent who only needs half of the newsletter.
Seeing as there are three coins, which means there are 3 heads and 3 tails.There's only a 50% chance it'll land on either side one one coin. I believe the chances to get two heads, and one tail would be somewhere around 80%, since there are only 8 possible outcomes.
