Your answers may vary slightly. 5.2 Normal Distributions: Finding Probabilities If you are given that a random variable Xhas a normal distribution, nding probabilities corresponds to nding the area between the standard normal curve and the x-axis, using the table of z-scores. The mean (expected value) and standard deviation ˙should be given
Step-by-step explanation:
Given the sequence:
6, 10, 14, 18,...
We will find the 75th term
The given sequence is an arithmetic sequence
Because there is a constant common differnce
d = 18 - 14 = 14 - 10 = 10 - 6 = 4
The first term = a = 6
The general formula of the arithmetic sequence is as follows:
![a_n=a+d(n-1)](https://tex.z-dn.net/?f=a_n%3Da%2Bd%28n-1%29)
Where: n is the nth term
To find the 75th term, substitute with n = 75 and a = 6, d = 4
![a_{75}=6+4\cdot(75-1)=302](https://tex.z-dn.net/?f=a_%7B75%7D%3D6%2B4%5Ccdot%2875-1%29%3D302)
So, the answer will be the 75th term = 302
Answer:
See below
Step-by-step explanation:
The mean score and the standard deviation are needed
L-s=16
4s-5=l
4s-l=5
3s=21
s=7
l-7=16
l=16+7
l=23
The smaller number is 7 and the greater number is 23
