Given : A rectangular picture frame has a perimeter of 52 inches. The height of the frame is 12 inches.

To Find : The width of the frame .

Solution : Let us take the width of the frame be x . So , we know the formula to find the perimeter of rectangle as ;

$\boxed{\red{\bf Perimeter_{rectangle}=2(l+b)}}$

Where , l is the length of the rectangle and b is the breadth of the rectangle .

⇒ Perimeter = 2 ( l + b ) .

⇒ 52 in. = 2 ( 12 + x ) in.

⇒ 52 in.= 24in. + 2x .

⇒ 2x =( 52 - 24 ) in

⇒ 2x = 28 in.

⇒ x = 28/2 in.

⇒ x = 14 in.

Hence the width of the rectangle is 14 inches.

Answer:

(0.869, 12.33104)

Step-by-step explanation:

N1 = 110

N2 = 225

S1 = 24.8

S2 = 25.8

Bar x1 = 169.9

Bar x2 = 163.3

Difference in mean = 169.9 - 163.3 = 6.6

We use the z score

Alpha = 0.05

Z critical value at this alpha level = 1.96

We find standard error

√s1²/n1+s2²/n2

= √(24.8²/110 + 25.8²/225)

= 2.9239

Confidence interval

6.6 +-1.96(2.924)

(6.6-5.73104, 6.6+5.73104)

= (0.869, 12.331)
