Answer:
c is the ans because l ans m r || so angle are sam the ans is 64
Answer:
a ) JKM=
- 90+25+JKM=180°(sum of angle of triangle)
- JKM=180-115
- JKM=65°
b) NJM
- 37+NJM=90° {given in figure}
- NJM=90-37
- NJM=53°
c). JNM
- 53+25+JNM=180°(sum of angle of triangle)
- JNM=180-78
- JNM=102°

Answer:
0.01521
Step-by-step explanation:
The Margin of Error for Difference in Proportions is given as:
z × √p1 × (1 - p1)/n1 - p2 × (1 - p2)/n2
z = z score for 95% confidence interval
= 1.96
In 2018, out of 1542 respondents, 415 said it was the most important.
p1 = x1/n1
x1= 326 n1 = 1323
p1 = 326/1323
0.246409675
Approximately = 0.246
In 2012, out of 1323 respondents, 326 said it was the most important.
p2 = x2/n2
x2 = 415, n2 = 1542
p2= 415/1942
p2 = 0.2136972194
Approximately = 0.214
Margin of Error =
1.96 × √0.246× (1 - 0.246)/1323- 0.214 × (1 - 0.214)/1542
1.96 × √0.0005699169 - 0.0005097276
1.96 × √(0.0000601893)
1.96 × 0.0077581763
= 0.0152060256
Approximately = 0.01521
Therefore, Margin of Error = 0.01521
