Answer:
1) 1.203
2) 1.291
Step-by-step explanation:
1 mL = 0.001 L
1202.57120 mL = <u>1.202</u>57120 L
round to 4 sig fig = 1.203
1g = 10dg
0.1290743 g = <u>1.290</u>743 dg
round to 4 sig fig = 1.291
Answer:
A.99.7%
Step-by-step explanation:
We are given;
- Mean of a distribution, μ as 0.68 ounce
- Standard deviation, σ as 0.02 ounce
- The range values of X between 0.62 ounce and 0.74 ounce
We are required to calculate the percentage of the weight to be between 0.62 ounce and 0.74 ounce
Step 1: Calculate the Z-score
To get the Z-score we use the formula;
Z-score = (x-μ)/σ
Therefore, when x = 0.62
Then z score = (0.62 - 0.68 ) ÷ 0.02
= -3
When, x = 0.74
Then, Z score = (0.74 - 0.68) ÷ 0.02
= 3
Step 2: we use the Z-score table or the empirical rule
Using the Z-score table;
P(-3 < z < 3) = 99.7%.
Therefore; the percentage of mice that weigh between 0.62 ounce and 0.74 ounce is 99.7%.
Answer: I can help
Step-by-step explanation:
The number that produces an irrational number when multiplied by 0.4 is 3π. The correct option is A. 
To determine which number produces an irrational number when multiplied by 0.4
First and foremost, 0.4 is a rational number.
A rational number is a number that is of the form 
where p and q are integers and q is not equal to 0.
0.4 can be written as 
or 
, hence, it is a rational number.
Now,
Any irrational number when multiplied by a rational number other than zero will also be irrational.
Therefore, we are to determine which of the given options is an irrational number.
π is an irrational number, therefore 3π is also an irrational number
0.444... can be expressed as 4/9, therefore it is a rational number
- For option C.
= 3, which can be expressed as 3/1, therefore it is a rational number
- For option D.
is a rational number
The only irrational number among the given options is 3π
Hence, the number that produces an irrational number when multiplied by 0.4 is 3π. The correct option is A.
