It would be 4x-17+3x+8+x+13=180, so the first answer
For the triangle:
Measure base x height divided by 2
= 4 x 3 / 2
= 12 / 2
= 6 km squared
Semi Circle:
area of a circle = pi r squared
= 3.14 x 2 km squared (half of the 4km diameter)
= 3.14 x 4 (4 is 2 squared)
= 12.56 divided by 2 (since it’s half of a circle)
= 6.28 km squared
Total:
6 + 6.28 = 12.28 km squared
Answer:
a) 0.9964
b) 0.3040
Step-by-step explanation:
Given data:
standard deviation = $90,000
Mean sales price =$345,800
sample mean = $370,000
Total number of sample = 100
calculate z score for [/tex](\bar x = 370000)[/tex]


z = 2.689
P(x<370000) = P(Z<2.689)
FROM STANDARD NORMAL DISTRIBUTION TABLE FOR Z P(Z<2.689) = 0.9964
B)
calculate z score for (\bar x = 350000)


z = 2.133

FROM NORMAL DISTRIBUTION TABLE Z VALUE FOR


SO, = 0.9836 - 0.6796 = 0.3040
Answer:
*View attached graph*
Step-by-step explanation:
Graph those points on your coordinate plane
Hope this helps!
Solving it and nearing it to the hundredth would be 9.169 :)
