Answer:
About 72.23 metres
Step-by-step explanation:
Use Pythagorean Theorem to figure out all of the missing sides and then add them up. There are four right triangles you can do this with.
1) 26 different outcomes are in the sample space.
2) 1 / 26 is the probability that the computer produces the first letter of your first name.
<u>Step-by-step explanation:</u>
<u>1) You have to find out the different outcomes in the sample space :</u>
- A "Sample space" is defined as the set of all the possible outcomes of an event.
- Here, the given event is randomly selecting a letter from the alphabets.
Therefore, the sample space must contain all the possible alphabets that can be chosen randomly.
The sample space is the set of all the 26 alphabets in English language.
⇒ Sample space = {A,B,C,D...........,Y,Z}
⇒ 26 different outcomes.
<u>2) The probability the computer produces the first letter of your first name :</u>
Here, the required outcome is getting the first letter of your first name.
Probability = No. of required outcomes / total no. of outcomes.
For example, The name Alex Davis has the first letter of the fist name as alphabet 'A'.
∴ Probability = 1 / 26
Similarly, for any first name there is going to be any one alphabet from the 26 alphabets, thus the probability to get the first letter will be always 1 / 26.
Answer:
d = 711 miles
Step-by-step explanation:
The speed s of the car is given by :
...(1)
Where
d is the stopping distance
We need to find the stopping distance of a car travelling at 80 mph.
Rearranging equation (1) for d.
or
d = 711 miles
So, the required stopping distance is 711 miles.
If the repairman work x hours, then he will charge $35 an hour, so the total of $35*x.
Add to the above amount the $50 we get $(50+35x).
The correct answer is then B.
1. The semi inter quartile range is 10
2. The coefficient of quartile deviation is 0.2
<h3>1. How to determine the semi inter quartile range</h3>
- Mark: 20, 30, 40, 50, 60
- Freq: 5, 12, 27, 40, 50
- Com. freq: 5, 17, 44, 84, 134
- Semi inter quartile range =?
1st quartile (Q₁) = (134 + 1) / 4 = 33.75th = 40
3rd quartile (Q₃) = 3 (134 + 1) / 4 = 3 × 33.75 = 101.25th = 60
Semi inter quartile range = (Q₃ - Q₁) / 2
Semi inter quartile range = (60 - 40) / 2
Semi inter quartile range = 10
<h3>2. How to determine the coefficient</h3>
- 1st quartile (Q₁) = 40
- 3rd quartile (Q₃) = 60
- Coefficient of quartile deviation =?
Coefficient of quartile deviation = (Q₃ - Q₁) / (Q₃ + Q₁)
Coefficient of quartile deviation = (60 - 40) / (60 + 40)
Coefficient of quartile deviation = 0.2
