Answer:
18 is the number that would go in the green box 33/3 =11 and 54/3 = 18
Answer:
500 de no ficcion y 1500 de ficcion
Step-by-step explanation:
si tomamos que hay 2000 libros hay que buscar un numero que multiplicado 3 veces por si mismo nos de 2000, como ya tenemos el 500 que seria los libros de no ficcion, ahora tenemos que e si al multiplicarlo por 3 veces nos da los 1500 que nos falta para completar 2000
500 + 1500 = 2000
Answer:
Average speed
= 5 5/6 mph , or
= 5.83 mph (to 2 decimals)
Step-by-step explanation:
Average speed is total distance divided by the total time it takes to cover the given distance.
Since uphill = 5 mph, and downhill = 7 mph, we know the average speed is between 5 and 7 mph.
Let
x = distance uphill, and also distance downhill.
Total distance = 2x miles
Total time = x/5 + x/7 hours = 12x/35 hours
Average speed
= total distance/total time
= 2x / (12x/35) mph
= 70x / 12x
= 5 5/6 mph
= 5.83 mph (to 2 decimals)
A conservative vector field
has curl
. In this case,
so the vector field is not conservative.
<span>First and third results are coherent. They both represent a probability of 0.9. Because 9 out of 10 is 9/10 = 0.9, and 135 out of 150 = 135 / 150 = 0.9. Nevertheless, second result is not coherent because 32 out of 50 is 32/50 = 0.64. I think this number must be discarded, and use 0.9 as the experimental probaility. That means that for 300 trials you should obtain x / 300 = 0.9 => x = 0.9 * 300 = 270. Then, the answer is that you can expect that a yellow ball will be selected 270 times out of 300. </span>
