Answer:
x^2 + x-72=0
Step-by-step explanation:
x(x+1) =72
Distribute
x^2 +x = 72
Subtract 72 from each side
x^2 +x - 72 = 0
Now this is the equation we can factor
M = -1/2
B = 1
Equation shown is y = mx + b
The weight seems like most accurate to me, even thought you didn't show me what type of measurement he took.
To get the probability of selecting a person who is a
democrat and is favour to the issue, let us first calculate for the portions in
each party who is favour on the issue.
p (rep & favour) = 0.4 * 0.3 = 0.12
p (dem & favour) = 0.6 * 0.7 = 0.42
Therefore the total portions who are favour is:
p (favour) = 0.12 + 0.42 = 0.54
Hence the probability is:
P (dem & favour) = 0.42 / 0.54 = 0.7778 = 0.78
Therefore there is about 78% probability that the person
selected who is favour to the issue is a democrat.
Answer:
Triangular prism with a surface area of 144, C
Step-by-step explanation:
4 x 3 = 12, 12 divided by 2 ( x 1/2 ) = 6
6 x 2 = 12
3 x 11 = 33
4 x 11 = 44
5 x 11 = 55
12 + 33 + 44 + 55 = 144
