Is the degree to which a measure is free from random error. A) Reliability B) Validity C) Generalizability D) Utility E) Correlation

A. Reliability

Step-by-step explanation:

Reliability means getting result accurate and consistent when test or measurement which can be dependable. It is 100% free random error.

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
