The quiz grades of a math class are given. 83, 76, 68, 97, 68, 80, 89, 74, 75, 81, 91, 90 The grades are normally distributed wi
Yuki888 [10]
Answer:
the answer is c) 1.08
Step-by-step explanation:
Step1:
Formula for calculating z-score is;
Z= (x-mean)/standard deviation
where x is the value for which z-score is required
Step 2:
As asked in the question z-score for highest grade is required which is 91;
z= (91-81)/9.3
z=10/9.3
z=1.075
which is approximately;
z=1.08
B = 12 * 5 = 60
60 is the answer
Answer:
Angle DEB: 52
Angle ADB: 30
Angle CBE: 52
Angle BEC: 38
Step-by-step explanation:
Angle DEB = 52 because triangles' angles must add up to 180. Angle ADB is 30 because it is complementary to angle BDE. Angle CBE is 52 because angle BEC is complementary to BED which is 52 degrees to BEC is 38 degrees. since the angles add up to 180, and C is 90, CBE is 52. Finally, BEC is 38 because it is complementary to BED.
