Step-by-step explanation:
x P(x) 0 0.25 1 0.3 2 0.1 3 0.35 Find the standard deviation of this probability distribution. Give your answer to at least 2 decimal places
Answer:
The standard deviation of this probability distribution is 1.2.
Step-by-step explanation:
We have that:
P(X = 0) = 0.25
P(X = 1) = 0.3
P(X = 2) = 0.1
P(X = 3) = 0.35
Mean:
Each value multiplied by its probability. So
[tex]M = 0*0.25 + 1*0.3 + 2*0.1 + 3*0.35 = 1.55[/tex]
Variance:
Sum of the squares of the values subtracted from the mean, and multiplied by its probability.
[tex]V = 0.25*(0-1.55)^2 + 0.3*(1-1.55)^2 + 0.1*(2-1.55)^2 + 0.35*(3-1.55)^2 = 1.4475[/tex]
Standard deviation:
Square root of the variance. So
[tex]S = \sqrt{V} = \sqrt{1.4475} = 1.2[/tex]
The standard deviation of this probability distribution is 1.2.

The 81st percentile of time students sleep per night is ______hours.
Answer:
7 hours
Step-by-step explanation:
The formular of percentile is given as;
n = (P / 100) * N
where;
n = ordinal rank
P = Percentile
N = Number of values
The grades are given as;
5.5, 7, 6, 7, 6.5, 6, 9 , 6.5, 6.5 , 6.5
Arranging in increasing order;
5.5, 6, 6, 6.5, 6.5, 6.5, 6.5, 7, 7, 9
n = (81/100) * 10 = 8.1 ≈ 8
The 81st percentile is the 8th term.
The 8th term = 7

Consider an exchange economy with two people, A and B, and two commodities, food (x) and water (y). A's and B's preferences are described, respectively, by the following utility functions:
ua(Xa,Ya)= X^2aYa, MRSa(Xa,Ya)=2Ya/Xa
ub(Xb,Yb)=XbY^2b, MRSb(Xb,Yb)=Yb/2Xb
Suppose there are 6 units of x and 6 units of y overall.
1. Draw an Edgeworth box for this economy.
2. Determine whether each of the following allocations is (i) feasible, (ii) Pareto efficient
a. ( (2,4), (4,2) )
b. ( (4,2), (2,4) )
c. ( ( 8 / 3 , 1 ), ( 10/3 , 5 ) )
which formula should be used to find the area of the composite shape? A = 4(1/2Xbh) lw B. A=4bh+lw C. a=4bh+lw d. 2bh+bh The composite shape is a four pointed star.
Answer:
D. 2bh+bh
Step-by-step explanation:
You can divide that shape into five separate pieces, 4 triangles and 1 square.
The formula for the area of a triangle is A=1/2bh.
Multiply this by 4 becuase there are 4 triangles and you get A=2bh.
Then you add on the area of the square and you have A=2bh+bh

Compare: 2/3×(9+12)◯15×2/3
Answer:
[tex]\frac{2}{3}[/tex] (9 + 12) > 15 * [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
[tex]\frac{2}{3}[/tex] (9 + 12) = [tex]\frac{2}{3}[/tex] * 21 = 2 * 7 = 14
15 * [tex]\frac{2}{3}[/tex] = 5 * 2 = 10
14 > 10 ⇒ [tex]\frac{2}{3}[/tex] (9 + 12) > 15 * [tex]\frac{2}{3}[/tex]

Two numbers have a sum of 527 and a difference of 195. What is the smaller of the two numbers?
Answer:
166
Step-by-step explanation:
let two numbers be x and y
according to question,
x+y=527..........equation 1
x-y=195...........equation 2
add both the equations you will get
x=361 and y= 166
So the smaller of two numbers is y=166
