Answer:
The sample size 'n' = 72,030
Step-by-step explanation:
<u>Step(i):-</u>
<em>Given that the Estimate Error = 0.013</em>
<em>Given that the standard deviation of the Population = 1.5</em>
<em>The estimated error is determined by </em>
<em />
<em />
<u><em>Step(ii):-</em></u>
<em>Given that the Level of significance = 0.98 or 0.02</em>
<em>Z₀.₀₂ = 2.326</em>
<em>The estimated error is determined by </em>
<em> </em>
<em />
<em> </em>
<em />
<em> </em>
<em />
<u><em>Squaring on both sides, we get</em></u>
<em> n = 72,030</em>
<u><em>Final answer:-</em></u>
The sample size 'n' = 72,030

#5, 6 and 7
m<BAE = 59
m<BAC + m<CAD + m<DAE = m<BAE
4x - 20 + x + 12 + x + 1 = 59
6x - 7 = 59
6x = 59 + 7
6x = 66
x = 11
m<BAC = 4x - 20 = 4(11) - 20 = 24
m<CAD = x + 12 = 11 + 12 = 23
m<BAE = x + 1 = 11 + 1 = 12
answer
5.
m<BAC = 24
6.
m<CAD = 23
7.
m<BAE = 12
#8, 9 and 10
m<BAE = 130
m<BAC + m<CAD + m<DAE = m<BAE
3x - 10 + 2x + 5 + x + 15 = 130
6x + 10 = 130
6x = 120
x = 20
m<BAC = 3x - 10 = 3(20) - 10 = 60 -10 = 50
m<CAD = 2x + 5 = 2(20) + 5 = 40 + 5 = 45
m<DAE = x + 5 = 20 + 15 = 35
answer
8.
m<BAC = 50
9.
m<CAD = 45
10.
m<DAE = 35
Answer:
84 in.
Step-by-step explanation:
multiply 12 by 7
there are 12 inches in a foot and 7 feet
Answer:2
Step-by-step explanation:
7. Obtuse
8. Acute
9. No, because it’s the hypotenuse
10. Yes, because that part is not the hypotenuse and it is less than the greatest angle
