Answer with Step-by-step explanation:
Since we have given that
Number of students = 100
Mean = 21.3 years
In what way are descriptive statistics involved in this example?
As we know that descriptive statistics gives information that explains the data is specific manner and while measuring the mean age of the 100 students she needs to collect data by asking their age from them.
In what way are inferential statistics involved?
As we know that inferential statistics form inferences about given populations using given data, so when she estimate the mean age of 100 students, she will use data of 100 students. So, she is using inferential statistics.
The closest option to the actual answer is a.
1 5/18 is the actual answer.
If you make both the denominators the same, then you can actually add the fractions together.
To make both of the denominators the same, you need to multiply 5/6 by 9 and 4/9 by 6, which would result in 45/54 + 24/54= 69/54 = 23/18. If we convert it to a mixed fraction, it would result into 1 5/18.
Answer:
Step-by-step explanation:
First term = a =4
Common difference = d = 2nd term - first term
d = 8 - 4 = 4
Last term = l = 400
First we have to fin the number of terms 'n'
l = a + (n-1)d
4 + (n-1)*4 = 400
4 + 4n- 4 = 400
4n = 400 {Divide both sides by 4}
n = 400/4
n = 100
Answer:
None of them
Step-by-step explanation:
y=-x-5 => slope=-1
A. slope =-2/3
B. slope =-3/2
C. slope = 2/3
D. slope = 2/3
None of slope of the choices is -1
