Samuel used the distributive property to simplify the expression -6(-2 - 10x) - 7x and came up with 53x - 12 which is incorrect.
What is Samuel’s mistake? What is the correct answer?
1 answer:
Answer:
He messed up the signs, most likely by multiplying incorrectly. It should be 53x+12.
Step-by-step explanation:
You begin by multiplying both -2 and -10x by -6.
Remember a negative times a negative makes a positive.
-6(-2-10x)
12+60x
Then you need to combine like terms which are 60x and -7x
60x-7x
53x
So that means the final answer will be
53x+12

Answer:
0.347
Step-by-step explanation:
n = 3
p = 1/6
r = 1
Use binomial probability:
P = nCr pʳ qⁿ⁻ʳ
P = ₃C₁ (1/6)¹ (5/6)³⁻¹
P = 0.347
Or, using a calculator:
P = binompdf(n, p, r)
P = binompdf(3, 1/6, 1)
P = 0.347
The way it is written, none of them.
The "a"s cancel out.
