Which operation should you perform first when evaluating the expression 3²+ 2
2 answers:
<h3>Answer: Exponents is done first (evaluate 
first)</h3>
Explanation:
The acronym PEMDAS helps determine the order of operations
P = parenthesis
E = exponents
M = multiplication
D = division
A = addition
S = subtraction
With the expression we have two operations going on here: exponents and addition.
Since exponents comes before addition (E comes before A in PEMDAS), this means we evaluate first, then add later.

Answer:
(1, 0 )
Step-by-step explanation:
using the rule of logarithms
x = n ⇒ x =
, then
y = (x + 2) - 1
to find the zero let y = 0 , that is
(x + 2) - 1 = 0 ( add 1 to both sides )
(x + 2) = 1 , then
x + 2 = = 3 ( subtract 2 from both sides )
x = 1
the zero is (1, 0 )
Answer: Our required probability is 0.3162.
Step-by-step explanation:
Since we have given that
n = 60
Probability of success =
Probability that at most 39 of these relays come from supplier A would be
Hence, our required probability is 0.3162.
