Answer:
-21
Step-by-step explanation:
Answer: The required probability is 0.3.
Step-by-step explanation: Given that a small combination lock on a suitcase has 5 wheels, each labeled with the 10 digits from 0 to 9.
An opening combination is a particular sequence of 5 digits with no repeats.
We are to find the probability of a person guessing the right combination.
If the 5 digits do no repeat, then we have
10 options for first digit, 9 options for second digit, 8 options for third digit, 7 options for fourth digit and 6 options for fifth digit.
Let A denote the event that the combination is a particular sequence of 5 digits with no repeats.
Also, let S be the sample space for the experiment.
Then, we have
Therefore, the probability of even A is given by
Thus, the required probability is 0.3.
It's asking for miles/day (miles per day) meaning you would divide the number of miles by the number of days. So divide 1623 by 28.
1623/28=57.964
I think it is the first one: Different bar widths.
Each step of the proof are:
- a || b
- ∠1 ≅ ∠5
- ∠1 ≅ ∠5
- ∠5 ≅ ∠7
- ∠5 ≅ ∠7
- ∠1 ≅ ∠7
- ∠1 ≅ ∠7
<h3>How to complete the proof?</h3>
The given parameter is:
Lines a and b are parallel.
This is represented as; a || b
Corresponding angles are equal.
∠1 and ∠5 are corresponding angles.
So, we have: ∠1 ≅ ∠5
Also, they are congruent.
So, we have ∠1 ≅ ∠5
Vertical angles are equal.
∠5 and ∠7 are vertical angles.
So, we have: ∠5 ≅ ∠7
Also, they are congruent.
So, we have ∠5 ≅ ∠7
According to the transitive property;
If ∠1 ≅ ∠5 and ∠5 ≅ ∠7, then ∠1 ≅ ∠7
Hence, it has been proved that ∠1 ≅ ∠7
