Answer:
Opción b, P(2) = 0
Step-by-step explanation:
Tenemos la expresión:
P(y) = y^2 - 7*y + 10
Para encontrar el valor P(2), simplemente debemos remplazar todas las "y" en la expresión de arriba por el valor 2, asi obtenemos:
P(2) = 2^2 - 7*2 + 10 = 4 - 14 + 10 = (4 - 14) + 10 = -10 + 10 = 0
P(2) = 0
La opción correcta es b.
A special 8 sided die is rolled 20 times with these outcomes: 2, 4, 7, 3, 1,5, 4, 6, 3, 8, 6, 2, 5, 2, 6, 1, 7, 4, 5, 6 What is

In your data set, 2 and 4 each show up 3 times. The experimental probability of rolling a 2 or 4 is 6/20 = 0.30.
The theoretical probability of rolling one of 2 given numbers out of 8 is 2/8 = 0.25. The experimental probability in this case is greater than the theoretical probability.
Using Pythagoras's theorem, we can get that 60 inches is the hypotenuse and 52 inches is one of the legs. 60^2 - 52^2 = b^2, where b is the leg that we are trying to find, aka the length of the shadow. We find that b^2 = 896. The square root of 896 is closest to 30 inches, therefore the answer is A) 30 inches
Answer:
An expression is 6 + 10.
or you might be able to write it as "An expression is 6 + 10 = 16.
It's the triangle 30° - 60° - 90°.
The sides are in proportion 1 : √3 : 2 (look at the picture).
Therefore we have:
