Answer:
130 ± 1.82 inches i.e the range of the values is 128.18 inches to 131.82 inches.
Step-by-step explanation:
The range of values required here implies the values fall between the least and maximum values.
Since the values can vary by 1.4%, the range can be determined by:
1.4% of 130 =
x 130
= 0.014 x 130
= 1.82
The addition or subtraction of 1.82 to/from 130 inches gives the required range.
i.e the range of allowable values = 130 ± 1.82 inches.
Thus,
130 - 1.82 = 128.18 inches
130 + 1.82 = 131.82 inches
The values falls between 128.18 inches to 131.82 inches.
Probability of green= # of green marbles ÷ total # of marbles
= 6 ÷ (6 + 9)
= 0.4 OR
Answer:
6 and 18 are common because 6x3=18. Remember the rule to multiply all numbers by 3. So multiply 10 by 3 and you will get 30. The total number of square tiles needed is 30 tiles. If you are putting it into a ratio it would be 18:30.
