Answer: 3 and 3/7
explanation:
Answer:
a) 1133.98 ≈ 1134 packs
b) 125 packs
Step-by-step explanation:
Given:
Tar present in 1 cigarette = 5 mg
Nicotine present in 1 cigarette = 0.4 mg
Number of cigarettes in 1 pack = 20
thus,
Tar present in 1 pack of cigarette = 5 × 20 = 100 mg
Nicotine present in 1 pack of cigarette = 0.4 × 20 = 8 mg
now,
1 oz = 28349.5 mg
thus,
for 4 oz = 4 × 28349.5 mg = 113398 mg
Therefore,
Number of packs required for 4 oz ( 113398 mg ) tar
=
= 1133.98 packs ≈ 1134
also,
Number of packs required for 1 g (1000 mg) nicotine
=
= 125 packs
Answer: Need more info. We need to know how many minutes over the 300 minutes were used in order to calculate the correct monthly fee.
Step-by-step explanation:
Answer:
The approximation is 0.2( real value is 0.19)
Step-by-step explanation:
In this question, we are to calculate the best approximation if in a pack of cards labeled 1 to 21 , the card selected is a multiple of 5
First we know that the total number of options in our sample space is 21; from 1 to 21
now let’s get the multiples of 5. we have 5,10,15 and 20
The probability of selecting a multiple of 5 is thus; 4/21 . This can be approximately be said to be 0.2 ( actual value is 0.19)
