Answer:
(x,y) -> (-x,-y)
Step-by-step explanation:
You need the opposites of both points, not just one of them.
First you combine 8x and -2x which is -6x
and 5+-1=4
y=-6x+4
Answer:
Our answer is 0.8172
Step-by-step explanation:
P(doubles on a single roll of pair of dice) =(6/36) =1/6
therefore P(in 3 rolls of pair of dice at least one doubles)=1-P(none of roll shows a double)
=1-(1-1/6)3 =91/216
for 12 players this follows binomial distribution with parameter n=12 and p=91/216
probability that at least 4 of the players will get “doubles” at least once =P(X>=4)
=1-(P(X<=3)
=1-((₁₂ C0)×(91/216)⁰(125/216)¹²+(₁₂ C1)×(91/216)¹(125/216)¹¹+(₁₂ C2)×(91/216)²(125/216)¹⁰+(₁₂ C3)×(91/216)³(125/216)⁹)
=1-0.1828
=0.8172
Well, 18 yards is 54 feet.
3. yes because -31 is lower than -27
4. it would cost $40 because you would buy 60 cups and plates
