Answer:
0.999
Step-by-step explanation:
At least 1 correct means, 1 correct, 2 correct, 3 correct ... until 10 correct. That would be a long process to calculate.
<em>Instead we use the complement rule to calculate.</em>
<em></em>
<em />
<em>So we need to find P(x<1). So this is getting 0 answers correct, or 10 incorrect.</em>
<em />
In true false question, probablity of correct is 1/2 and incorrect is 1/2, hence,
Probability of 10 incorrect is (1/2)^10
Thus,
So the answer is 0.999 (rounded to nearest thousandth)
Answer: The volume is 90.47
Step-by-step explanation:
1. To solve this problem you need to use the formula for calculate the density, which is shown below:
Where is the mass and
is the volume.
2. You must solve for the volume, as following:
3. Now, you must substitute the values of the mas and the density, which are given in the problem. Therefore, you have:
