That question mark is filled in with the y-intercept. The y-intercept is where the graph goes through the y-axis. Our graph goes through the y-axis at 1, so the equation is y = 4x + 1

Answer:

Sample size is $n=423$

Step-by-step explanation:

Given that,

Margin of error $=4$ %

Confidence level $=90$ %

Suppose, sample proportion $=0.5$

i.e. $\hat{P}=0.5$

We know that,

Margin of error $=2^*\sqrt{\frac{\hat{p}(1-\hat{p})}{n} }$

∴ $1.64\sqrt{\frac{0.5(0.5)}{n} } \leq 4\%$

$\Rightarrow 1.64\sqrt{\frac{0.25}{n} } \leq 0.04$

$\Rightarrow \frac{0.5}{\sqrt{n} } \leq \frac{0.04}{1.64}$

$\Rightarrow \frac{0.5}{\sqrt{n} } \leq 0.0243$

$\Rightarrow \sqrt{n}\geq \frac{0.5}{0.0243}$

$\Rightarrow \sqrt{n}\geq 20.57$

squaring on both side,

∴ $n=423.1249$

Hence, the sample size is,

$n=423$

Hence, the correct option is $(b).$

Answer:

Step-by-step explanation:

All of the other functions are functions that are just multiplicative. When we substitute any x for A, B,or C, y/x will be the same. In D y/x will vary.
