Answer:

1 yard / 36 inches = 7 yards / 252 inches

Step-by-step explanation:

1 inch / 2.54cm = 7 inch/ 17.68 cm

1 foot / 12 inches = 7 feet / 74 inches

1 yard / 36 inches = 7 yards / 252 inches

1 meter / 3.28 feets = 7 meters / 22.86 feets

To establish the correctness of the statements above , we express the fractions in decimals and see if the right hand side = left hand side

1 inch / 2.54cm = 7 inch/ 17.68 cm

0.3937007 = 0.3959276 (incorrect)

1 foot / 12 inches = 7 feet / 74 inches

0.0833333 = 0.0945945 (incorrect)

1 yard / 36 inches = 7 yards / 252 inches

0.0277777 = 0.0277777 (correct)

1 meter / 3.28 feets = 7 meters / 22.86 feets

0.3048780 = 0.3062117 (incorrect)

The numbers of choices in each category are multiplied together. We assume the order of paint choices matters: using color 1 in area A and color 2 in area B is not the same as using color 2 in area A and color 1 in area B.

P(7,2)*4*3*2 = 42*4*3*2 = 1008 ways

_____
P(n, k) = n!/(n-k)!

There are 6 red socks and 8 black
RideAnS [48]

Answer:

24/91

Step-by-step explanation:

6 red socks and 8 black = 14 socks

P( red) = red/total = 6/14 = 3/7

Keep the red sock

5 red socks and 8 black = 13 socks

P(black) = black / total = 8/13

P(red, black, keeping the sock) = 3/7 * 8/13 = 24/91

I need help on #10. very confused
RideAnS [48]

Step-by-step explanation:

\displaystyle f'(x) = \lim_{h \to 0} \dfrac{f(x + h) - f(x)}{h}

\:\:\:\:\:\displaystyle = \lim_{h \to 0} \dfrac{(x+h)^2 -7 -(x^2 - 7)}{h}

\:\:\:\:\: \displaystyle= \lim_{h \to 0} \dfrac{(x^2 +2hx + h^2 -7) - (x^2 -7)}{h}

\:\:\:\:\: \displaystyle= \lim_{h \to 0} \dfrac{2hx + h^2}{h}

\:\:\:\:\: \displaystyle= \lim_{h \to 0} (2x +h)

\:\:\:\:\: \displaystyle= 2x
