Answer:
x^2+3x+2
Step-by-step explanation:
(X+2)(x+1)
Is x^2+x+2x+2
x^2+3x+2
Answer:
16.2
Step-by-step explanation:
By geometric mean theorem:
Answer:
-48
Step-by-step explanation:
Multiply both sides of the equation by -8
-8(6) = 
(-8)
-48 = w
Considering it's concept, it is found that the number of outcomes in the sample space is of 9.
<h3>What is the sample space of an experiment?</h3>
The sample space is the <u>set that contains all possible outcomes for an experiment</u>.
In this problem, there are 2 trials, each with 3 possible outcomes(red, blue or green), hence the <u>number of possible outcomes</u> is given by:
N = 3² = 9.

Answer:
ΔT = ΔT0 e^-K T
As I understand Newton's Law of Cooling
ΔT at any time is the difference between the temperature and the surroundings
Originally ΔT0 = 95 - 22 difference between 95 and room temperature
65 - 22 = 33 = 73 e^-KT where t is time to cool to 65 deg
ln (33/73) = -KT K = .794 / 5 = .159 where 5 is time to cool to 65 deg
40 - 22 = 73 e^-.159 T where t is time to cool to 40 deg
18 = 73 e^-.159 T
ln (18 / 73) = -.159 T
T = 8.8 min
It would take 8.8 min for the object to cool to 40 deg C
Suppose the object cooled from 95 to 90 deg, then
ln 68 / 73 = -.159 T and T = .45 min
