V=4/3πr^3, so substitute what you know. Input the volume so you only have to solve one variable, the r, radius.
I would say yes but I could be wrong.
X would equal -2 so another words please mark meas a brainlyiest answer
Answer:The height of the building which caste a shadow 20.5 m in length is 17.5 m.
Step-by-step explanation:
Given : At a particular time of a day, a 7 high flagstaff castes a shadow which is 8.2 m long.
To find : What is the height of the building which castes a shadow 20.5 meters in length at the same moment?
Solution :
A 7 high flagstaff castes a shadow which is 8.2 m long.
i.e. Shadow of length 8.2 m = 7 m
The shadow of length 1 m = m
The shadow of length 20.5 m = m
The shadow of length 20.5 m = 17.5 m
Therefore, The height of the building which caste a shadow 20.5 m in length is 17.5 m.
Answer:
The probability that a particular driver had exactly two speeding violations is 0.009.
Step-by-step explanation:
We are given that a sample of 2,000 licensed drivers revealed the following number of speeding violations;
<u>Number of Violations</u> <u>Number of Drivers</u>
0 1,910
1 46
2 18
3 12
4 9
5 or more <u> 5 </u>
<u>Total</u> <u> 2000 </u>
<u />
Now, the data means that 1,910 drivers had 0 speeding violations and so on.
Now, we have to find the probability that a particular driver had exactly two speeding violations, that means;
Number of drivers having exactly two speeding violations = 18
Total numbers of drivers = 2000
So, the required probability =
=
= <u>0.009</u>
