Answer:

10 cm²

Step-by-step explanation:

The area of a square = s², where s is the measure of the side

To calculate the side use Pythagoras' identity

Consider the lower side with right triangle legs 3 and 1, then

side² = 3² + 1² = 9 + 1 = 10 ( take the square root of both sides )

side = $\sqrt{10}$ , thus

area = ( $\sqrt{10}$ )² = 10 cm²

Answer:

z=-1.591

Step-by-step explanation:

Null Hypotheses,

$H_0 : p=0.8\\H_a: p>0.80$

So we use z-test for one population proportion (right-tailed test)

According to this informaton, we defined that

$\alpha=0.05$

$z_c=1.64$ (critical value)

So our Rejection region is $R={z:z>1.64}$

$z=\frac{\bar{p}-p_0}{\sqrt{p_0(1-p_0)/n}} = \frac{0.755-0.8}{\sqrt{0.8(1-0.8)/200}}=-1.591$

Not rejection.
