Two equations for the constant of proportionality equal to 1/2

NemiM [27]

y=kx and y= $\frac{k}{x}$ are two equations of constant of proportionality

Step-by-step explanation:

There are two equations for the constant of proportionality. That is

(i) Direct proportion

(ii) Inverse proportion

In direct proportion y=kx, Now

if x increases, then y also increases and if x decreases, then y also decreases. So, k is a constant proportionality.

In Inverse proportion y= $\frac{k}{x}$ , Now

if x increases then y decreases and if x decreases, then y increases and k is a constant proportionality.

In direct proportion, we put y=1 and x=2, So k= $\frac{1}{2}$ .

So, the equations y=kx and y= $\frac{k}{x}$ are two equations of constant of proportionality.

Melanie uses 8.1 pints of blue paint and white paint to paint her bedroom walls. 2/5 of this amount is blue paint, and the rest

attashe74 [19]

Answer:

4.86

Step-by-step explanation:

Melanie uses 8.1 pints of blue paint and white paint for her bedroom

2/5 of this amount is blue paint

Therefore the amount of white paint can be calculated as follows

= 2/5

= 0.4×100

= 40%

60/100 × 8.1

= 0.6 × 8.1

= 4.86

Hence 4.86 pints of white paint will be used to paint the bedroom

ASAP HELP: If a sample proportion is 0.55, which range of possible values best describes an estimate for the population paramete

iris [78.8K]

Answer:

B.(0.4,0.7)

Step-by-step explanation:

We are given that

Sample proportion

$\hat{p}=0.55$

We have to find the range of possible values which describes best an estimate for the population parameter.

Estimate for the population parameter

$\hat{p}\pm Z(SE)$

A.(0.55,0.6)

Difference between 0.55 and 0.55=0

Difference between 0.55 and 0.6=0.05

Difference between 0.55 and 0.55 is not equal to difference between 0.55 and 0.6.

Hence, option A is wrong.

B.(0.4,0.7)

Difference between 0.55 and 0.4=0.15

Difference between 0.55 and 0.7=0.15

Difference between 0.55 and 0.4 is equal to difference between 0.55 and 0.7.

Hence, option B is correct.

C. (0.4,0.69)

Difference between 0.55 and 0.4=0.15

Difference between 0.55 and 0.69=0.14

Difference between 0.55 and 0.4 is not equal to difference between 0.55 and 0.69.

Hence, option C is not correct.

D.(0.5,0.59)

Difference between 0.55 and 0.5=0.05

Difference between 0.55 and 0.59=0.04

Difference between 0.55 and 0.5 is not equal to difference between 0.55 and 0.59.

Hence, option D is not correct.
