Answer:
20300m^2
Step-by-step explanation:
first try to imagine the shape bisected into a rectangle and a triangle
to find the missing part of the triangle or the bottom side you need to subtract 70m from 140 m
140m-70m=70m this will be the base of your triangle
now you need the side
230m-60m=170
triangle formula base x height/ 2
70m x 170m=a
11900m=a
now the rectangle
base x height=a
60m x140m=a
8400m=a
finally add the two quantities together
8400m+11900m=a
20300m^2=a
Step 1. Add 72 to both sides
5y = 7 + 5x + 72
Step 2. Simplify 7 + 5x + 72 to 5x + 79
5y = 5x + 79
Step 3. Divide both sides by 5
y = 5x + 79/5
is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output.
Answer:
The mean is given by:
And the deviation:
Step-by-step explanation:
For this case we assume that the true population proportion of Americans do not know that GOP stands for Grand Old Party is 0.55 and we select a random sample of n = 953 americans
For this case we assume that we satisfy the conditions to use the normal approximation for 
1) np >10 , n(1-p)>10
2) Independence
3) Random sample
4) The sample size is less than 10% of the population size
We assume that all the conditions are satisfied and the distribution for would be:
The mean is given by:
And the deviation:
Step-by-step explanation:
Since they are complementry angles :
(12x-9) + (8x + 14) = 90°
20x + 5 = 90°
X = 4.25 °
Angles are 42° and 48°.
