Answer:
Solution (1, 4)
Step-by-step explanation:
x = y - 3
x + 3y = 13
Substitute x = y - 3 into x + 3y = 13
y - 3 + 3y = 13
4y - 3 = 3
4y =16
y = 4
Substitute y = 4 into x = y - 3
x = 4 - 3
x = 1
Solution (1, 4)
Answer:
The function will be: f(n) = 2n
Step-by-step explanation:
An arithmetic sequence is a sequence where the common difference between consecutive terms is same
The sequence according to given information is:
2,4,6...
Here
a_1 = 2
a_2 = 4
a_3 = 6
the common difference will be:

The arithmetic sequence is given by:

Putting the values

Hence,
The function will be: f(n) = 2n

Answer:
Kindly check explanation
0.57691
0.4719
Step-by-step explanation
A.) The distribution of sample means must follow a normal distribution ;
Mean = 64 ; Standard deviation = 17 ;
Standard Error = s/sqrt(n) = 17 / sqrt(20) = 3.8013155
N(64 ~ 17)
Given that:
mean (m) = 64
Sample size (n) = 20
Standard deviation (s) = 17
Find
P(x < 67.3)
Z = (x - m) / s
Zscore = (67.3 - 64) / 17
Zscore = 0.1941176
P(Z < 0.194) = 0.57691 (Z probability calculator)
(c) Find P(x > 65.2).
Zscore = (65.2 - 64) / 17
Zscore = 0.0705882
P(Z > 0.0705) = 0.4719 (Z probability calculator)
Took the quiz myself, 15/17 is the answer.
