Answer:
And solving we got:

So then for the problem given the probability that the entire bath will be accepted (none is defective among the 4) is 0.583
Step-by-step explanation:
For this case we can model the variable of interest with the hypergeometric distribution. And with the info given we can do this:
Where N is the population size, M is the number of success states in the population, n is the number of draws, k is the number of observed successes
And for this case we want to find the probability that none of the scales selected would be defective so we want to find this:

And using the probability mass function we got:
And solving we got:

So then for the problem given the probability that the entire bath will be accepted (none is defective among the 4) is 0.583
Answer:
C) angle 7
Step-by-step explanation:
angle 7
Answer:
Análisis del problema
Nos dan como datos el tiempo que se tarda cada uno en pintar la habitación:
Gerardo: 3 horas
Ángel: 6 horas
La velocidad de trabajo podemos definirla como dada por la cantidad de habitaciones que pueden pintar sobre el tiempo: H/t
Gerardo: 1 hab /3h
Ángel: 1 hab / 6h
Sumamos ambas velocidades de trabajo:
Por lo tanto entre los dos pintarían una habitación en dos horas.
As you can see in the image, point C must be (-2, -2), because it is the only point that will create a right triangle that is in the third quadrant.
To find the distance between point A and point C, just subtract the y-values.
Answer: 40km/h
Step-by-step explanation:
distance = 20km
time = 30 min conver to hours. 
velocity = ?
