Answer:
The percentage of people that could be expected to score the same as Matthew or higher on this scale is:
= 93.3%.
Step-by-step explanation:
a) Data and Calculations:
Mean score on the scale, μ = 50
Distribution's standard deviation, σ = 10
Matthew scores, x = 65
Calculating the Z-score:
Z-score = (x – μ) / σ
= (65-50)/10
= 1.5
The probability based on a Z-score of 1.5 is 0.93319
Therefore, the percentage of people that could be expected to score the same as Matthew or higher on this scale is 93.3%.
Answer:
Option (b).
Step-by-step explanation:
Given expression is :
8(1 + 2i) – (7 – 3i)
Using distributive property :
8+16i-7+3i
Taking like terms together,
1+19i
(1+19i) is the simplified expression for the given expression. He did not apply distributive property correctly for 8(1 + 2i). He forgets to multiply 8 with 2i.
