<h3>(8.4 + 10.3) + (–4.1) = 8.4 + (10.3 + (–4.1)) is a example of associative property of addition</h3>
<em><u>Solution:</u></em>
Given that we have to find the associative property of addition
When we add, we can group the numbers in any combination
<em><u>Option A</u></em>
–(18.9 + 3.2) = –18.9 + (–3.2)
Here, negative sign outside the bracket is distributed to terms inside the bracket
This is not a example of associative property
<em><u>Option B</u></em>
–5.5 + 7.9 = 7.9 + (–5.5)
By commutative property of addition,
a + b = b + a
This, is commutative property of addition
<em><u>Option C</u></em>
–17.5 + 0 = –17.5
This is also not a example of associative property
<em><u>Option D</u></em>
(8.4 + 10.3) + (–4.1) = 8.4 + (10.3 + (–4.1))
We can group the numbers in any combination
This is a example of associative property of addition
Answer:
6a + 2
Step-by-step explanation:
2 ×3a = 6a 2×2 = 4
it gives 6a + 4

Answer:
Step-by-step explanation:
p = 0.05 ( or 5%)
n = 12
Part b)
Expected value = n X p
expected value = 12 X 0.05
Expected value = 0.60
Part c)
Batch will be accepted if the number of defectives is less than 2
P(accepted) = P( x = 0) + P (x = 1)
where x = number of defectives
From binomial formula;
P(X=x) = nCx X p^x X (1-p)^(n-x)
we got n = 12, p = 0.05
P(x=0) = 12C0 X 0.05^0 X (0.95)^12
P(x=0) = 0.54036
P(x=1) = 12C1 X (0.05)61 X (0.95)^11
P(x=1) = 0.34128
P(accepted) = 0.54036 + 0.34128
P(accepted) = 0.88164
Part d)
Standard deviation = √(0.05 X 0.95/12) = 0.062915
