Answer:
0.6,0.4,212500
Step-by-step explanation:
Given that the executive believes the price she will get by leaving the house on the market for another month is uniformly distributed between $200,000 and $225,000
Let X be the price of the house by leaving in another month in thousands
X is Uniform
Ranges are 200 and 225
Hence pdf of X is
a)
b)
c)
d) Expected selling price = E(X) =
~212500 dollars in actual
The solution to the given equation is .
Expression is a finite combination of symbols that is well-formed according to rules that depend on the context. An expression is a combination of numbers, variables, or a combination of numbers and variables, and symbols and it is connected by the sign of equal.
We have,
Expression -8(2a - 1) = 36
So,
Now,
To get the solution to this expression,
i.e.
-8(2a - 1) = 36
Rewrite it as,
i.e.
Opening Brackets,
We get,
-16a + 8 = 36
Now,
Taking variable terms on one side and other terms on another side,
We get,
-16a = 36 - 8
On solving we get,
-16a = 28
i.e.
a =
So,
The solution to the given equation is .
Hence, we can say that the solution to the given equation is .

Answer:
Height of fir tree = 9 meters
height of pine tree= 12 meters
Step-by-step explanation:
The combined height of one fir tree and one pine tree is 21 meters. The height of 4 fir trees stacked on top of each other is 24 meters taller than one pine tree.
Let x be the height of fir tree and y be the height of pine tree
Subtract x from both sides
height of 4 fir trees = pine tree +24
Substitute 21-x or y in the above equation
Add x on both sides
Divide by 5 on both sides
x=9
Now plug in 9 for x and find out y
y=12
Height of fir tree = 9 meters
height of pine tree= 12 meters
