you are dealt one card from a standard 52 card deck. find the probability of being dealt a card greater than 2 and less than 8

1 answer:

8 0

The given range is comprised of cards with a value between 3 and 7, inclusive, and there are 4 of each from the available suits. So there are 20 cards that fit the bill.

The probability of drawing 1 such card is

$\dfrac{\binom{20}1}{\binom{52}1}=\dfrac{20}{52}=\dfrac5{13}$

Find the scale factor and ratio of perimeters for a pair of similar octagons with areas 36 ft squared and 49 ft squared.

vagabundo [1.1K]

Answer:

scale factor: 1.16

perimeters: 21.84 ft and 25.36 ft

Step-by-step explanation:

The area for an octagon is as follows:

$A = 2*l^{2}(1+\sqrt{2})\\$

solved for "l":

$l = \sqrt{\frac{A}{2*(1+\sqrt{2}) } }$

now we calculate the value of each side:

$l1 = \sqrt{\frac{36}{2*(1+\sqrt{2}) } }$

l1 = 2.73

$l2 = \sqrt{\frac{49}{2*(1+\sqrt{2}) } }$

l2 = 3.17

The scale would be:

3.17 / 2.73 = 1.16

And the value of the perimeter of the first would be:

2.73 * 8 = 21.84

and the second:

3.17 * 8 = 25.36

PLEASE HELP! DUE IN 15 minutes!!

klemol [59]

Answer:

I think 49 is the answer

Step-by-step explanation:

Because a straight angle measures 180 degrees so if one angle is 131 you just subtract 131 of 180 and it will give you the angle missing.

180-131=49

21 radical sign p^-4/p^3

slavikrds [6]

Answer: $p^-^\frac{1}{3}$

$\sqrt[21]{\frac{p^-^4}{p^3} }$

$\sqrt[21]{p^-^4^-^3}$

$\sqrt[21]{p^-^7}$

$\sqrt[21]{\frac{1}{p^7}}$

$\frac{\sqrt[21]{1} }{\sqrt[21]{p^7} }$

$\frac{1}{p^\frac{7}{21} }=\frac{1}{p^\frac{1}{3} }=p^-^\frac{1}{3}$
