Step-by-step explanation:
The data provided is as follows:
25 to 34 45 to 54
1329 2268
1906 1965
2426 1149
1826 1591
1239 1682
1514 1851
1937 1367
1454 2158
Compute the mean and standard deviation for the group "25 to 34" as follows:
Compute the <em>z</em>-score for the group "25 to 34" as follows:
Compute the mean and standard deviation for the group "45 to 54" as follows:
Compute the <em>z</em>-score for the group "45 to 54" as follows:
Thus, the <em>z</em>-score for the group "25 to 34" is 0.37 and the <em>z</em>-score for the group "45 to 54" is 0.25.
Answer:
y = 1
x = -1
Step-by-step explanation:
- 4x + 11y = 15
2 = 2y
Find y from the second equation
2 = 2y
2/2 = 2y/2
1 = y
Substitute y into the first equation.
- 4x + 11y = 15
- 4x + 11(1) = 15
- 4x + 11 = 15
-4x = 15 - 11
-4x/-4 = 4/-4
x = -1
