Question 18 Write an equation that expresses the following relationship. varies directly with and inversely with In your equatio
Svetach [21]

Answer:

d=\frac{kw}{p^2 }

where k is the constant of proportionality.

Step-by-step explanation:

The original question is

d varies directly with w and inversely with the square of p

k is always the constant of proportionality

d varies directly with x so we multiply 'w' in the numerator

for inversely proportional we put the square of  p in the denominator

so the equation becomes

d=\frac{kw}{p^2 }

where k is the constant of proportionality.

A contractor is required by a county planning department to submit one, two, three, four, five, or six forms (depending on the n
Ratling [72]

Answer:

a)

k = \dfrac{1}{21}

b) 0.476

c) 0.667    

Step-by-step explanation:

We are given the following in the question:

Y = the number of forms required of the next applicant.

Y: 1, 2, 3, 4, 5, 6

The probability is given by:

P(y) = ky

a) Property of discrete probability distribution:

\displaystyle\sum P(y_i) = 1\\\\\Rightarrow k(1+2+3+4+5+6) = 1\\\\\Rightarrow k(21) = 1\\\\\Rightarrow k = \dfrac{1}{21}

b) at most four forms are required

P(y \leq 4) = \displaystyle\sum^{y=4}_{y=1}P(y_i)\\\\P(y \leq 4) = \dfrac{1}{21}(1+2+3+4) = \dfrac{10}{21} = 0.476

c) probability that between two and five forms (inclusive) are required

P(2\leq y \leq 5) = \displaystyle\sum^{y=5}_{y=2}P(y_i)\\\\P(2\leq y \leq 5) = \dfrac{1}{21}(2+3+4+5) = \dfrac{14}{21} = 0.667
