Answer:
m∠JLK° = 62°
Step-by-step explanation:
∠JLK = ∠KJL
SO
56°+2(∠JLK)° = 180°
2(∠JLK)° = 180-56
2(∠JLK)° = 124
∠JLK° = 62°
so m∠JLK° = 62°
Answer: C
The value n represents the number of trials in the binomial distribution. As you increase the number of n, you are increasing the number of bars that would be in your distribution. In effect, you are making it look more and more like a simple bell curve as you increase the number of bars, because they are getting closer together.
Answer:
The mean aptitude score is 3.14.
Step-by-step explanation:
The given frequency table is
Aptitude Score : 0 1 2 3 4 5
Frequency : 1 2 2 2 3 4
Formula for Mean
![Mean=\dfrac{\sum f_ix_i}{\sum f_i}](https://tex.z-dn.net/?f=Mean%3D%5Cdfrac%7B%5Csum%20f_ix_i%7D%7B%5Csum%20f_i%7D)
First find
.
![x\quad\quad f_i \quad\quad f_ix_i](https://tex.z-dn.net/?f=x%5Cquad%5Cquad%20f_i%20%5Cquad%5Cquad%20f_ix_i)
0 1 0
1 2 2
2 2 4
3 2 6
4 3 12
5 4 20
Sum = 14 44
Substitute
in the above formula.
![Mean=\dfrac{44}{14}](https://tex.z-dn.net/?f=Mean%3D%5Cdfrac%7B44%7D%7B14%7D)
![Mean\approx 3.14](https://tex.z-dn.net/?f=Mean%5Capprox%203.14)
Therefore, the mean aptitude score is 3.14.
