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

Answers

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.

What is 1.83 repeating as a fraction?

Answers

The answer to this question would be: 1 5/6

To change a decimal number into fraction, you need to divide the number on the right of decimal point with 1. In this case, the number is 0.83.
This number is hard since .83 doesn't have many factors. To find the answer you can try to multiply the decimal with some number until it close to 1(no decimal left)
0.83* 2= 1.66
0.83* 3= 2.49 ---> close to half, if you find this number, you can try to double it
0.83* 4= 3.32
0.83* 5= 4.15
0.83* 6= 4.98---> close to 1, that means there is high probability that the number can be divided by 6 
0.83 would be 4.98/6, but if we assume that the number is 0.8333...... then 0.83 would be 5/6. So, 1.83 would be 1 5/6

1.83838383... = 182/99

1.83333333... = 11/6

1.83183183... = 610/333

Further explanation

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.

T_n = a + (n-1)d

S_n = (1)/(2)n ( 2a + (n-1)d )

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.

T_n = a ~ r^(n-1)

S_n = (a( 1 - r^n ) )/(1 - r)

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

\large {\boxed {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

\large {\boxed {X = (11)/(6) } }

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

\large {\boxed {X = (610)/(333) } }

There are two square roots of 25. what is there only one sneer for the radius of the button.

Answers

Answer:

Given: Square root of 25 .i.e., √(25)

When we find the √(25) . we get 2 answers that are +5 , -5

As, (+5)^2 = 25 . Also (-5)^2=25

but while selecting value for radius we choose positive value of √(25) .i.e, +5 because Radius of circle should be a positive value as it is a Length.

When finding the square root of any number there is is the + and - rootwhen using this information to solve a problem only the positive root is usedyou can't solve involving measurements using the - roothope this helps
