A number cube with faces labeled from 1 to 6 was rolled 20 times. Each time the number
kari74 [83]

Answer:

0.4

Step-by-step explanation:

These are the relative frequencies of each face (data are missing in the text of the problem):

Number Showing  on Top Face   Frequency

1 0

2 3

3 3

4 6

5 3

6 5

The probability to obtain a certain number when throwing the dice is given by

p(x_i)=\frac{f_i}{\sum f}

where

f_i is the relative frequency of the number x_i to occur

\sum f is the sum of the relative frequencies

Here the sum of the frequencies is:

\sum f=0+3+3+6+3+5=20

For number 5 here, we have:

f_5 = 3 (from the table)

So the probability of getting a 5 is

p(5)=\frac{3}{20}

For number 6 here, we have

f_6=5

So the probability of getting a 6 is

p(6)=\frac{5}{20}

So the probability to obtain either a 5 or a 6 in the next rolling is:

p(5\cup 6)=p(5)+p(6)=\frac{3}{20}+\frac{5}{20}=\frac{8}{20}=0.4

If a=i-2j and b= 2i - xj are parallel, then x is.....<br>a) 4 3 2 ) 2 d 4.​
cupoosta [38]

Answer:

x = 4

Step-by-step explanation:

a = i-2j

b = 2i-xj

1 = k•2

-2 = k•(-x)

=> 1/2 = k

=> (-2)/(-x) = k

=> 1/2 = (-2)/(-x) => 1/2 = 2/x => x = 4
