Answer:

The sample size is $n =419$

Step-by-step explanation:

From the question we are told that

The population proportion is $p = 0.45$

The margin of error is $E = 0.04$

Given that the confidence level is 90%

Then the level of significance can be mathematically represented as

$\alpha = 100 -90$

$\alpha = 10\%$

$\alpha = 0.10$

Next we obtain the level of significance from the normal distribution table the value is

$Z_{\frac{\alpha }{2} } = 1.645$

Generally the sample size is mathematically represented as

$n = [ \frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * p(1- p )$

substituting values

$n = [ \frac{1.645 }{0.04} ]^2 * 0.45(1- 0.45 )$

$n =419$

Logan is flying a kite that is made yo if three similar rectangles. The sides of the three rectangles are in the ratio 1:2:3. If

Ad libitum [116K]

To solve the question we need to note that:
area scale factor=(linear scale factor)^2
linear scale factor=1:2:3
Area scale factor=1^2:2^2:3^2=1:4:9

Hence, given that the area of the smallest triangle is 72 sq. inches, the area of:
medium triangle will be:
4/1*72=288 sq. inches

largest triangle will be:
9/1*72=649 sq. inches
