Remember PEMDAS ( Parentheses, Exponents, Multiplication⇔ Division, Addition ⇔ Subtraction), This is the order you work expressions in.

Answer:
6x²
Step-by-step explanation:
The GCF of 24 and 36 is 6
The GCF of x³ and x² is x²
Thus the GCF of 24x³ + 36x² is 6x²
Answer: A) 71.498 ; b) 0.00152
Step-by-step explanation:
Given the following :
Number of atoms that decayed during 365 days period = 26,097
Number of days = 365
Mean number of radioactive atoms that decayed in a day:
Mean = number of decayed atoms / number rof days
Mean = 26,097 / 365
Mean = 71.498 atoms per day
B.) probability that 50 radioactive atoms decayed in a given day:
Using the poisson distribution formula :
P(x =x) = (m^x * e^-m) ÷ x!
Where m = mean
Mean (m) = 71.498
P(x = 50) = (71.498^50 * e^-71.498) / 50!
P(x = 50) = (71.498^50 * 2.7182818^-71.498) / 50!
= 4.60795E61 / 50!
= 0.0015150
Answer:
4x
Step-by-step explanation:
Answer:
y = 11
Step-by-step explanation:
(y+8)-3=16
y + 8 - 3 = 16
y + 5 = 16
y = 11
