Answer:
The joint probability distribution of X and Y is shown below.
Step-by-step explanation:
The distributions of X and of Y are described as follows:
X : 0 1
P (X) : 0.23 0.77
Y : 1 2 3
P (Y) : 0.40 0.22 0.38
It is provided that X and Y are independent.
That is:
P (X ∩ Y) = P (X) × P (Y)
Compute the joint probability distribution of X and Y as follows:
X 0 1
<u>Y </u>
1 0.9200 0.3080
2 0.0506 0.1694
3 0.0874 0.2926
Answer:60
Step-by-step explanation:
Pythagorean's theorem gives us 100^2-80^2=b^2
Simplifying this we get:
10000-6400=b^2
3600=b^2
b=60
Answer:
67
Step-by-step explanation:
because the total amount is 180.
so there is 23 +90+x=180so find the number the number is 67
23+90+67=180
Answer:
you can cross multiply or u can 7/20 to get the answer that 7 is 35% of 20
Answer:
So you need to compute all the rates to see which is the best deal.
$1.79/12.5ft^2=$0.1432 per ft^2
$5.29/40ft^2=$0.13225 per ft^2
$8.49/50ft^2=$0.1698 per ft^2
$6/60ft^2=$0.10 per ft^2
So the last option is the cheapes per square foot and thus is the best deal. Ordered from least to greatest.
