Namely, how much is 18.3% from 188? well if we take 188 to be 100%, then

$\bf \begin{array}{ccllll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
188&100\\
x&18.3
\end{array}\implies \cfrac{188}{x}=\cfrac{100}{18.3}\implies \cfrac{188\cdot 18.3}{100}=x$

Select the correct answer from each drop-down menu.

Answer:

Area of ΔXYZ = n(r * r) square units

Step-by-step explanation:

Sides of ΔABC are 30 units, 40 units and 60 units.

Corresponding sides of another triangle XYZ are r times as long as the sides of ΔABC.

Therefore, sides of ΔXYZ will be, 30r units, 40r units and 60r units.

Perimeter of the triangle XYZ = 30r + 40r + 60r

= 130r units

If the area of ΔABC = n square units

Then the ratio of the area of ΔXYZ and ΔABC = (Ratio of the sides of ΔXYZ and ΔABC)²

$\frac{\text{Area of triangle XYZ}}{\text{Area of triangle ABC}}=(\frac{\text{Side length of XYZ}}{\text{Side length of triangle ABC}})^2$

$\frac{\text{Area of triangle XYZ}}{n}=(r)^2$

Area of ΔXYZ = nr² ≈ n(r * r)

Therefore, Option (3) will be the answer.

Marketing companies are interested in knowing the population percent of women who make the majority of household purchasing deci

zimovet [89]

Answer: 271

Step-by-step explanation:

As per given description in the question, we have

Critical value for 90% confidence interval = $z_{\alpha/2}=1.645$

[using z-value calculator ]

Margin of error : E= 0.05

Since prior estimate of population proportion is unknown so we take p= 0.5

Formula we use to find the sample size :

$n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2$ [we assume p= 0.50]

i.e. $n=0.5(1-0.5)(\dfrac{1.645}{0.05})^2$

Simplify :

$\Rightarrow\ n=270.6025\approx271$

Therefore , the minimum sample size required = 271
