Answer:
60 and 25
Step-by-step explanation:
The range is the difference between the maximum value and the minimum value.
maximum value = 125, minimum value = 65
range = 125 - 65 = 60
------------------------------------------
The interquartile range is the difference between the upper quartile Q₃ and the lower quartile Q₁
Q₃ is the value at the right side of the box = 115
Q₁ is the value at the left side of the box = 90
interquartile range = 115 - 90 = 25
Range= 54,36,18,0
Domain= 63,45,27,9
Answer:
102
Step-by-step explanation:
Let the unknown measure be x
So all the angles add up to 180
therefore,
13 + 65 + x = 180
78 + x = 180
x = 180 - 78
x = 102

Answer:
a) p = 352/700 = 0.5029
b) p = 348/700 = 0.4971
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
There are 700 shoppers.
151 + 201 = 352 were happy with the service received.
133 + 215 = 348 were not happy with the service received.
(a) A shopper was happy with the service received.
352 happy out of 700
p = 352/700 = 0.5029
(b) A shopper was unhappy with the service received.
348 unhappy out of 700
p = 348/700 = 0.4971
The equation of variation in which y varies jointly as x and z and inversely as the product of w and p is y=0.5(xz/wp).
Given that variable y varies jointly as x and z and inversely as the product of w and p,where y=7/28 where x=7,z=4,w=7 and p=8.
We are required to find the equation of variation.
To solve this problem we must apply the following procedure:
1) We have that y varies jointly as x and z and inversely as the product of w and p. Therefore we can write the following equation,where k is the constant of proportionality:
y=k(xz/wp)----------1
Now we have to solve for the constant of proportionality as done under:
k=ywp/xz-------------2
Using the values in equation 1.
k=(7/28)(7)(8)/(7)(4)
=0.5
Using all the values in the equation 2.
y=0.5(xz/wp)
Hence the equation of variance is y=0.5(xz/wp).
Question is incomplete.The following values should be included:
y=7/28 where x=7,z=4,w=7 and p=8.
