Standard form is x + y = number.
y = -2/5 x
y + 2/5 x = 0
2/5 x + y = 0
In standard form, the coefficient of x or y cannot be a fraction.
Therefore we have to multiply the whole equation by 5.
2x + 5y = 0
The
formula for the population proportion is:
n = p ± Zc 
where p =
confidence level = 0.2
n =
proportion = 0.22
= standard error = 0.01
Finding for Zc:
.20+(.01)=.22
Zc = 2
Referring to Critical value table for standard
normal curve, a Zc value of 2 is equivalent to 95% Confidence Level.
Answer: 95% Confidence Level
Answer:
23.54 m
Step-by-step explanation:
Applying
cos∅ = adjacent(A)/hypotenuse(H)
cos∅ = A/H................ Equation 1
make H the subject of the equation
H = A/cos∅............ Equation 2
Given: A = 15 m, ∅ = 25°
Substitute into equation 2
H = 15/cos25
H = 16.55 m
Also,
tan∅ = opposite(O)/Adjacent(A)
tan∅ = O/A............Equation 3
Make O the subject of the equation
O = Atan∅.......... Equation 4
Substituting into equation 4
O = 15(tan25°)
O = 6.99 m.
From the diagram,
The height of the goal post before snap = H+O
The height of the goal post before snap = 16.55+6.99
The height of the goal post before snap = 23.54 m
Answer: 28.27
Step-by-step explanation: first multiply the radius by itself 3 times 3 = 9
then take 9 and multiply it by 3.14 which is 28.27
