Javier used the expression below to represent his score in a game of mini-golf.
2 answers:
Answer: The correct options are
(2) The coefficient is 2.
(3) The constant is 5.
(6) There are two terms.
Step-by-step explanation: Given that Javier used the expression below to represent his score in a game of mini-golf :
We are to select the correct statements about the parts of the simplified expression if Javier simplifies the expression.
The simplification of expression (i) is as follows :
Therefore, we get
the constant term is 5,
the coefficient of x is 2
and
There are two terms.
Thus, options (2), (3) and (6) are correct.

As the problem states, to solve this, we are going to use the equation 
where
is the loudness in dB
is the intensity of a sound
<span>is the minimum intensity detectable by the human ear
</span>
We know for our problem that
; we also now that the minimum intensity detectable by the human ear is 
, so 
. Lets replace those values in our equation to find :
Qe can conclude that since the explosion is under 100dB, it does not violates the regulation of the town. We used tow physical values to calculate the answer: the intensity of the sound of the explosion,
, and the minimum intensity detectable by the human ear 
.

We know for our problem that
Qe can conclude that since the explosion is under 100dB, it does not violates the regulation of the town. We used tow physical values to calculate the answer: the intensity of the sound of the explosion,
Answer:
D. 0.1353
B. 0.0473
Step-by-step explanation:
For an exponentially distributed random variable, the cumulative distribution function is:
with parameter λ=2, then P(X≥1) is equal to:
D. 0.1353
with parameter λ=1.5, then P(2≤X≤4) is equal to
B. 0.0473
