Answer:
You did the same on both exams.
Step-by-step explanation:
To compare both the scores, we need to compute the z scores of both the exams and then compare the values. The formula for z-score is:
<u>Z = (X - μ)/σ</u>
Where X = score obtained
μ = mean score
σ = standard deviation
For Exam 1:
Z = (95 - 79)/8
= 16/8
<u>Z = 2</u>
For Exam 2:
Z = (90 - 60)/15
= 30/15
<u>Z = 2</u>
<u>The z-scores for both the tests are same hence the third option is correct i.e. </u><u>you did the same on both exams.</u>
Answer:
∠ DBE = 25.5°
Step-by-step explanation:
Given ∠ DBC = 90° and ∠ DBE + ∠ EBC = ∠ DBC, then
∠ DBE = ∠ DBC - ∠ EBC = 90° - 64.5° = 25.5°
Answer:
16
Step-by-step explanation:
(7-4)= (3+8) =(11-3) = (8+9) = (17-1) = 16
