Answer:
a) 0 , 1
b) 0.56 , 0.06
Step-by-step explanation:
X = 0.2
Y = 0.3
Find the distribution of X + Y
<u>a) All the possible values of X + Y </u>
The possible values of X + Y are ; 0,1
<u>b) The probabilities that X + Y takes each of the values </u>
P(X+Y=0 ) = ( 1-0.2 )*(1-0.3) = 0.56
P( X +Y = 1) = 0.2*0.3 = 0.06
Based on the current population and the rate of decrease, the population in five years will be 88,529 people.
<h3>What is the rate of change of the amount?</h3>
Rate of change is used to mathematically describe the percentage change in value over a defined period of time, and it represents the momentum of a variable.
This can be found by the formula:
= Current population x ( 1 - rate%) ^ number of years
Given that,
Current population = 100,000, rate = 3%, number of years = 4
= 100,000 x
= 100,000 x 0.88529281
= 88,529 people
Hence, The population in five years will be 88,529 people.

Answer:
A y < -1/2
Step-by-step explanation:
4/3 < -8/3 y
Multiply both sides by 3
3×4/3 < 3× -8/3 y
4 < - 8y
Divide both sides by -8
4/-8 > -8y/-8
The inequality sign changes by dividing by negative
-1/2 > y is same as y < -1/2
Therefore
y < -1/2

Answer:
x=6,-4
Step-by-step explanation:
Use the formula (b/2)^2 in order to create a new term. Solve for x by using this term to complete the square.
x=6,-4
