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
Answer:
65%
Step-by-step explanation:
To find percentage, take the number out of the whole number, and divide it by the whole number. In this case, 1495 out of 2300 said they are satisfied. To find the percent, we have to do 1495/2300=0.65, which is 65%.
Answer:
P ( Z < 72 ) = 0.8577 or P ( Z < 72 ) = 85.77 %
Step-by-step explanation:
We know:
-A normal distribution
-Mean μ = 69.0 in
-Standard deviation σ = 2.8 in
- Population n = 350
And doors height 72 in
If passengers will pass through the door without bending that means he must be under 72 in tall, therefore we are looking for the probability of men under 72 in, to find such probability we compute the value of Z according to
Z = ( X - μ ) / σ ⇒ Z = ( 72 - 69 ) / 2.8
Z = 1.07
Now with this value we look the Z tables, to find a value of: 0.8577
So the probability of select a men and that he can fit through the door is
P ( Z < 72 ) = 0.8577 or P ( Z < 72 ) = 85.77 %
13
Divide 52 by 4 which gives you 13. 13 x 4 = 52
Step-by-step explanation:
I think option A is the correct answer
Because it is in ascending order
