Answer:
Option (A) 7% to 33%
Step-by-step explanation:
Data provided in the question:
Total number of students , n = 60
Number of students received more than 80 = 12
Probability of number of students received more than 80, p = = 0.2
Confidence level = 99%
Now,
percentage of all students of PPPP who received more than 80 for the final exam of the Basic Statistics
⇒ p ±
here,
z = 2.58 for 99% confidence level
Thus,
⇒ 0.2 ±
or
⇒ 0.2 ± 0.13
or
⇒ ( 0.2 - 0.13 ) to ( 0.2 + 0.13 )
or
⇒ 0.07 to 0.33
or
⇒ 7% to 33%
Hence,
Option (A) 7% to 33%
If two angles and included side of one triangle are equal to two angles and the included side of the other triangle , then the two triangles are congruent (ASA rule).
in figure
- consider triangle ABD and ACD
- Angle BAD = angle CAD
- AB = AC
- Angle B = angle C
- triangle ABD congruent to Triangle ACD ( by ASA rule)
Answer:
see work attached and shown
+7 would be the answer i believe
