Answer:
K 20
Step-by-step explanation:
f(x) = 7x2 - 4x
f (2) = 7 (2)^2 - 4(2)
= 28 - 8
= 20
Since they replaced the x inside f(x) with 2, just do that the same to the right side, change all x into 2
Answer:
224
Step-by-step explanation:
(100+12)*2
Answer:
0.6173 = 61.73% probability that the product operates.
Step-by-step explanation:
For each integrated circuit, there are only two possible outcomes. Either they are defective, or they are not. The integrated circuits are independent. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
An electronic product contains 48 integrated circuits.
This means that 
The probability that any integrated circuit is defective is 0.01.
This means that 
The product operates only if there are no defective integrated circuits. What is the probability that the product operates?
This is P(X = 0). So


0.6173 = 61.73% probability that the product operates.
Answer:
$14.40
Step-by-step explanation:
$180 * 8% ( Or 0.08 )
The sentence is converted into a mathematical equation will be 3n + 5 = n + n + 1/3. Then the correct option is C.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Five more than three times the number is one-third more than the sum of the number and itself.
Let the number be n.
Then convert the sentence into a mathematical equation. Then the equation will be
3n + 5 = n + n + 1/3
The sentence is converted into a mathematical equation will be 3n + 5 = n + n + 1/3. Then the correct option is C.
