Pani-rosa [81]3 years ago

Solution 1.

Number of times the dice is rolled

= 11 + 22 + 7 + 8 + 13 + 19

= 80

Number of time 4 appeared = 8

Probability

= No. of preferred outcomes/Total number of outcomes

= 8/80

= 1/10

= 0.1

Solution 2.

Number of times the dice is rolled

= 11 + 22 + 7 + 8 + 13 + 19

= 80

Number of time 2 appeared = 22

Probability

= No. of preferred outcomes/Total number of outcomes

= 22/80

= 11/40

= 0.275

2s to expect if dice is rolled 400 times

= 0.275 × 400

= 110

Cost of sushi= $40

Tax= 5%

Tax

<span>|7x-7|+3 = 4x+1  ⇒⇒⇒ add (-3) to both sides
</span>
<span>∴ |7x-7| = 4x - 2
</span>
According to the absolute rule
∴ 7x - 7 = 4x - 2    OR    -(7x - 7) = 4x - 2                                 
    7x - 4x = 7 - 2      l     7x - 7 = -4x + 2                              
   3x = 5                   l     7x + 4x = 2 + 7                                         
  x = 5/3                   l     11 x = 9  ⇒⇒⇒  x = 9/11

∴ x = 5/3  and  9/11


So, the correct answer is option <span>B. 5/3 and 9/11</span>
