Answer:
X=-2
Y=0
Step-by-step explanation:
X+y=-2 = x=-2-y
3x+4y=-6
3(-2-y)+4y=-6
-6-3y+4y=-6
y=0
x+3(0)=-2
x=-2
-13 because if you 33 and subtract 46 you would have -13 sorry dont really know how to explain

Answer:
0.0879 is the probability that out of 5 randomly selected consumers, three are comfortable with delivery by drones.
Step-by-step explanation:
We are given the following information:
We treat drone deliveries as a success.
P(consumers comfortable having drones deliver) = 25% = 0.25
Then the number of consumers follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
We have to evaluate:
P(Exactly 3 customers out of 5 are comfortable with delivery by drones)
Here,
Putting values, we get,
0.0879 is the probability that out of 5 randomly selected consumers, three are comfortable with delivery by drones.
Answer:
3.5(11) means 3.5 times 11? in that case
Step-by-step explanation:
first one roughly = 35+19+16....then you can see 77 is the closest, even without calcatulor
second one precisely==20+33+5+38.....then you can see that 90 is roughly the closest one, again even without to add those 4 togetherly precisely
