Find the value of y for a given value of x, if y varies directly with x

1 answer:

It is said that y varies directly to x which can be written as follows:

y = kx

where k is the constant of proportionality.

To be able to solve the problem, we need to determine the value of k. We do as follows:

y = kx
-252 = k(84)
k = -3

y = -3x
y = -3(74)
y = -222

Hope this helps. Have a nice day.

tekilochka [14]

Answer:

a) 25

b) 49

c) 97

Step-by-step explanation:

The sample size is calculated using the formula, n = $(\frac{\sigma\times z}{\textup{Margin of error}})^2$

Now,

for 95% confidence level value of z-factor = 1.96

Given:

Mean = $3.94

standard deviation = $0.25

thus,

a) for margin of error = $0.10

n = $(\frac{\sigma\times z}{\textup{Margin of error}})^2$

or

n = $(\frac{0.25\times1.96}{\textup{0.10}})^2$

or

n = 4.9²

or

n = 24.01 ≈ 25 (Rounded off to next integer)

b) for margin of error = $0.07

n = $(\frac{\sigma\times z}{\textup{Margin of error}})^2$

or

n = $(\frac{0.25\times1.96}{\textup{0.07}})^2$

or

n = 7²

or

n = 49

c) for margin of error = $0.05

n = $(\frac{\sigma\times z}{\textup{Margin of error}})^2$

or

n = $(\frac{0.25\times1.96}{\textup{0.05}})^2$

or

n = 9.8²

or

n = 96.04 ≈ 97 (Rounded off to next integer)
