Answer:
Refer below
Step-by-step explanation:
a) a and b are the lower and higher values of the interval for which uniform distribution is defined.
Here a= 6 and b =10
b) Mean of the uniform distribution= (a+b)/2 = (6+10)/2 =8
Or int x (1/4) dx = x^2/8 = 8
c) Variance of the uniform distribution = (b^2-a^2)/12 = (100-64)/12
= 36/12 =3
Std dev = sq rt of 3 = 1.732
d) To find total area
PDF of the distribution = 1/(b-a) = 1/4, 6<x<10
Area = \int 6 to 10 of 1/4 dx
= x/4
Subtitute limits
= (10-6)/4 =1
So total area = 1
d)P(X>7) = int 7 to 10 of 1/4 dx = 3/4
e) P(7<x<9) = Int 7 to 9 of 1/4 dx = 2/4 = 1/2
Answer:
4/8
Step-by-step explanation:
y^2-y^1/ x^2-x^1
-1-3/ -4-4 =-4/-8
I hope this helped!!
Answer:
y = 10x.
Step-by-step explanation:
Hayley is considering two gym membership plans. The plans are detailed here.
Plan One: $50 for a monthly pass plus $3 for each gym visit
Plan Two: $10 for each gym visit.
Therefore, if variable y is the total cost and x variable is the number of gym visit per year, then y will be given in the plan two by the equation
y = 10x ........ (1) (Answer)
Answer:
120 pounds
Step-by-step explanation:
15 boxes = 45 pounds
45/15= 3
1 box= 3 pounds
40 x 3 = 120
40 boxes would weigh 120 pounds
