Step-by-step explanation:
Answer:
0.2 ; 100 ; 4.84
Step-by-step explanation:
Given that the probability of each of the 5 groups is the same :
Sum of probability = 1
Hence, Probability of each group = 1 / number of groups = 1 / 5 = 0.2
Expected number for each interval for a sample of 500 : ; X = 500
E(X) = X * P(x) = 500 * 0.2 = 100
Goodness of fit (X²) :
X² = Σ(X - E)² ÷ E
Groups :
113, 95, 108, 99, and 85
X : 113 ____ 95 ____ 108 ____ 99 _____ 85
(113 - 100)^2 / 100 = 1.69
(95 - 100)^2 / 100 = 0.25
(108 - 100)^2 / 100 = 0.64
(99 - 100)^2 / 100 = 0.01
(85 - 100)^2 / 100 = 2.25
(1.69 + 0.25 + 0.64 + 0.01 + 2.25) = 4.84
17/8 mxm=m,2
Answer: 17/8 m,2

Answer:
3.52x
Step-by-step explanation:
Let
Quantity of tickets=4
Price of tickets=x
Discount=12%
This means, you will pay 100% -12%
=88%
Total amount payable=discount (quantity * price)
= 88% ( 4 * x )
= 0.88 (4x)
= 3.52x
There is only one requirement for three sides in order to be considered possible in constructing a triangle. That requirement is
<em>The sum of any of the two sides must be greater than the third side</em>
11 + 15 = 26 > 21
11+ 21 = 33 > 15
15 + 21 = 16 > 11
Since all of the combination fulfill the requirement, yes we could create the triangle with those sides.
