15y...for 12 months = 15(12) = 180 <==
ANSWER
EXPLANATION
We want to simplify:
Recall the distributive property;
(a+b)(c+d)=a(c+d)+b(c+d)
We apply this property to get,
We expand to get,
This simplifies to,
The simplest form of the given expression is:
This is impossible to answer because your question is incomplete.
Step-by-step explanation:
for a
- a+,38°=90°{ angle at circumference through center is 90°}
- a=90-38
- a=52°
for e
- e=38°{base angle of isosceles triangle r equal}
for d
- 38°+e+d=180°{sum of angle of triangle}
- d=180-76
- d=104°
for. c
- c+d=180°{straight angle}
- c=180-104°
- c=76°
for b
- a+b+c=180°{sum of angle of triangle}
- b=180-128
- b=52°

In finding this value you average lower and upper bound
(0.6+0.82)/2 = 0.71
=0.71 estimated
margin of error = distance from estimate point lower/ upper bound
This interval will be twice margin error
(0.82-0.6)/2 = 0.11
How far is 0.82 from 0.71 ??
=0.11=11%
