Answer:

8 and 2/3

Step-by-step explanation:

6 1/2 turns into an improper fraction which would be 13/2.

Then you turn the division into multiplication using KCF.

KEEP the 13/2

CHANGE the division sign into multiplication

FLIP the 2/3 to its reciprocal 3/2

Then solve the multiplication equation and your answer should be 8 and 2/3.

A rectangle is drawn so that the width is 3 feet shorter than the length. The area of the rectangle is 70 square feet. Find the

Vedmedyk [2.9K]

Answer:

The length of the rectangle (l) = 10 cm

The width of the rectangle (w) = 7 cm

Step-by-step explanation:

Step(i):-

Let 'x' be the length of the rectangle

Given that the width is 3 feet shorter than the length

The width of the rectangle = x -3

Area of the rectangle = length × width

Step(ii):-

Area of the rectangle = length × width

= x ( x-3)

Given that the area of the rectangle = 70 square feet

x ( x-3) = 70

⇒ x² - 3x - 70 =0

⇒ x² - 10 x + 7 x - 70 =0

⇒ x (x -10) +7( x-10) =0

⇒ ( x+7) ( x-10) = 0

⇒ x =-7 and x=10

Final answer:-

we choose x=10

The length of the rectangle (l) = 10 cm

The width of the rectangle (w) = 7 cm

Answer: 1308

Step-by-step explanation:

Given : Level of confidence = 0.97

Significance level : $\alpha=1-0.97=0.03$

Critical value : $z_{\alpha/2}=2.17$

Margin of error : $E=0.03$

If prior proportion of population is unknown , then the formula to find the population proportion is given by :-

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

$\Rightarrow n=0.25(\dfrac{2.17}{0.03})^2=1308.02777778\approx1308$

Hence, the minimum sample size needed =1308
