arrive late. Valerie used the random-number table to find the experimental probability that of 5
flights, at least 2 will arrive late. The digit 0 represents flights arriving early. The digits 1,2,3,
4, 5, and 6 represent flights arriving on time. The digits 7, 8, and 9 represent flights arriving
late. Find the experimental probability that of 5 flights at least 2 will arrive late.
A: 3/10
B:2/5
C: 9/20
D: 11/20
Answer:
D. 11/20
Step-by-step explanation:
7, 8, and 9 represent late flights. We want to count how many of the 20 trials have at least two of these digits. Counting, we find that 11 of the 20 have at least two of these digits.
D. 11/20
Firstly , let us learn about types of sequence in mathematics.
Arithmetic Progression is a sequence of numbers in which each of adjacent numbers have a constant difference.
Tn = n-th term of the sequence
Sn = sum of the first n numbers of the sequence
a = the initial term of the sequence
d = common difference between adjacent numbers
Geometric Progression is a sequence of numbers in which each of adjacent numbers have a constant ration.
Tn = n-th term of the sequence
Sn = sum of the first n numbers of the sequence
a = the initial term of the sequence
r = common ratio between adjacent numbers
Let us now tackle the problem!
Since the question is not clearly stated, then let me assume the problem is to convert 1.83838383... as a fraction.
Let :
X = 1.8383838383... = 1.83
100X = 183.83838383... = 183.83
100X - X = 183.83 - 1.83
99X = 182
X = 182 ÷ 99
If the problem is to convert 1.833333... as a fraction , then :
Let :
X = 1.833333... = 1.83
10X = 18.33333... = 18.3
100X = 183.3333... = 183.3
100X - 10X = 183.3 - 18.3
90X = 165
X = 165 ÷ 90
If the problem is to convert 1.83183183183... as a fraction , then :
Let :
X = 1.83183183183... = 1.83183
100X = 183.183183... = 183.183
100000X = 183183.183... = 183183.183
100000X - 100X = 183183.183 - 183.183
99900X = 183000
X = 183000 ÷ 99900

Answer:
Given: Square root of 25 .i.e.,
When we find the . we get 2 answers that are +5 , -5
As, . Also
but while selecting value for radius we choose positive value of .i.e, +5 because Radius of circle should be a positive value as it is a Length.
On solving the equation we get '- 8x'.
We have x - 9x.
We have to solve it.
The solution of a function f(x) is the value of x for which f(x) = 0.
According to the question -
f(x) = x - 9x
Now -
x - 9x = - 8x
Hence, on solving the equation we get '- 8x'.

Answer:
Step-by-step explanation:
-8x because x is jus an invisiable one and using the rule for subtracting. Intergers u get -8 and keep the variable.
