Let m be the side length of the fourth smallest possible square with integer value of its area, and let n be the sum of all prim
Natali [406]

Answer:

510

Step-by-step explanation:

It's assumed 0 is not an integer.

M is obviously 2. The area of a square is the square of its side length. If this area must be an integer, then it must be the fourth integer, which is 4. The side length, M=\sqrt{4} = 2

A prime number is a positive integer which can be divided exactly by only itself and 1. In fact, it has only those two factors. The last statement excludes 1 as a prime number. Hence, the prime numbers less than 10 are 2, 3, 5 and 7. Their sum is N=2+3+5+7=17.

To evaluate MN(N-M),

2\times17(17-2)=34\times15=510

Write an equation of the line in slope-intercept form (0,-2) ,(2,2)
Kipish [7]

Answer:

y=2x-2

Step-by-step explanation:

Slope intercept Formula: y=mx+b

y= Y coordinate

m = slope

x = x coordinate

b = y intercept

Point Slope Formula: y-y1=m(x-x1)

Slope Formula: m= y2-y1 / x2-x1

2 - (-2) / 2-0 = 4 / 2 = 2

y- (-2) = 2 (x - 0) = y+2=2x-0

y=2x-2

En un día de temporal de lluvia el meteorólogo dijo en las noticias que la probabilidad de que lloviera ese día era del 70%. ¿Qu
drek231 [11]

Answer:

Vamos a definir:

100% probabilidad de lluvia = Es seguro que ese día va a llover.

0% probabilidad de lluvia = Es seguro que ese día no va a llover.

Ahora, los valores intermedios admiten una dualidad, es decir, es posible que llueva o que no.

Particularmente en el caso del 70% significa que:

Si tenemos un dado de 10 caras, con los números {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

Y lo tiráramos, los resultados {1, 2, 3, 4, 5, 6, 7} indicarían que llueve.

Los resultados {8, 9, 10} indicarían que no llueve.

Entonces es mas probable que llueva, pero la probabilidad de que no llueva no es despreciable.
