Answer:

y = 1.6 x

y = 24

Step-by-step explanation:

The general equation of a direct variation is

y = k x

In this case

x = 10

y = 16

y = k*x

16 = 10*k

16/10 = k

k = 1.6

y = 1.6x

================

Let x = 15

y = 1.6 * 15

y = 24

user100 [1]

Answer: 543

Step-by-step explanation:

Given : Level of confidence = 0.98

Significance level : $\alpha=1-0.98=0.02$

By using the normal distribution table,

Critical value : $z_{\alpha/2}=2.33$

Margin of error : $E=5\%=0.05$

The formula to find the population proportion if prior proportion of population is unknown :-

$n=0.25(\dfrac{z_{\alpha/2}}{E})^2$

$\Rightarrow n=0.25(\dfrac{2.33}{0.05})^2=542.89\approx543$

Hence, the company survey minimum sample having size =543
