Well first I would subtract 7 because the seven books aren’t in the cartons, which will give you 120. Then you divide by 10 to get 12, the amount of cartons
-5 + -40 + -50 = -5 + 8 + 10
-95 = -13
Answer:
2.4%
Step-by-step explanation:
We make use of the binomial probability equation, which is as follows:
P = [n! / (n - r)! r!] p ^ r * q ^ (n - r)
where,
n total number samples = 20
r is the selected number = 8
p, sin este valor no se puede realizar el ejercicio y no lo mencionas, pero encontré una pregunta igual y era de 20.37%, es decir 0.2037
q = 1 - 0.2037 = 0.7963
reemplazando:
P = [20! / ((20 - 8)! * 8!)] * [0.2037 ^ 8 * 0.7963 ^ (20 - 8)]
P = 125970 * 1.92685405*10^-7
P = 0.024 = 2.4%

Answer:
b. y = (x - 5)² - 4
Step-by-step explanation:
Here, we take "standard form" to mean "vertex form."
In the US, "standard form" would be ...
y = x² -10x +21
Vertex form is ...
y = (x -5)² -4 . . . . matches B
