For the following frequency distribution, how many individual scores are in the entire set?
x: 5 - 4 - 3 - 2
f: 2 - 4 - 1 - 3
a. n = 54
b. n = 14
c. n = 10
d. impossible to determine

10

Step-by-step explanation:

The individual scores in the data are represented by frequency denoted by f column. f column depicts that how many times the individual scores are occurring in the data set. Hence to calculate the amount of individual score in the data set we simply add all frequencies. n=sum of f=2+4+1+3=10. Hence there are 10 individual scores present in the entire data set.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
