Answer:
Step-by-step explanation:
23.m∠2=x+60
as the sides are equal.
so angles are also equal.
m∠2=45
x+60=45
x=45-60=-15°
so C
24.
74+74+m∠2=180
m∠2=180-148=32°
so 3x-4=32
3x=32+4=36
x=12°
C
25.
as the three sides are equal so angle are equal.
m∠2=60
7x-10=60
7x=60+10=70
x=10
D
Answer:
The 95% confidence interval is from 64 to 88
Step-by-step explanation:
The confidence interval has two values.
The lower limit, that is the mean subtracted by the margin of error.
The upper limit, that is the mean added to the margin of error.
So the 95% confidence interval is
76-12 to 76+12 = 64 to 88
