Answer:
A gatekeeper
Step-by-step explanation:
"60 Minutes" is acting as a gatekeeper.
Gatekeeping is a theory in mass communication that involves selecting, and then filtering items of media that can be consumed within the time or space that is allocated to an individual. This means gatekeeping falls into a role of surveillance and monitoring data. Information is filtered for dissemination, for the purpose of publication, broadcasting, the Internet, or some other mode of communication.
Confidence interval is given by the formula
x ⁺/₋ z* ( σ/ (√n) )
Where:
x = the sample mean = 130
z* = the z-value for 90% confidence = 1.645
σ = standard deviaton = 7
n = sample size = 145
Substituting these values into the formula gives:
130 ⁺/₋
130 ⁺/₋ 0.956
So the interval is in between (130 - 0.956) and (130 + 0.956)
Answer:
Loki didn’t square a and b
Answer explained:
Pythagorean Theorem is a^2 + b^2 = c^2
Answer:
a = 4.8
Step-by-step explanation:
9 - 4a + 12 = 6a - 27
21 - 4a = 6a - 27
48 - 4a = 6a
48 = 10a
a = 4.8
