Iteru [2.4K]

The correct answer is
 Find the probability of selecting a diamond and then selecting a queen.

standard deck of 52 playing cards

hearts: 2, 3, 4, 5, 6, 7, 8, 9, 10, j, q, k, A---- > 13 cards

clubs: 2, 3, 4, 5, 6, 7, 8, 9, 10, j, q, k, A---- > 13 cards

spades: 2, 3, 4, 5, 6, 7, 8, 9, 10, j, q, k, A---- > 13 cards

diamonds: 2, 3, 4, 5, 6, 7, 8, 9, 10, j, q, k, A---- > 13 cards

a) The probability of selecting a diamond is 13/52

b) The probability of selecting a queen is 4/52

c) The probability of selecting a diamond and then selecting a queen is

(13/52)*(4/52)=0.0192------------->1.92%

Seth buys last year's best-selling novel, in hardcover, for $17.85 $⁢17.85 . This is with a 15% 15% discount from the original p

Troyanec [42]

$21.00

let the original price = 100%

then the discount price = 100 - 15 = 85%

divide $17.85 by 85 to obtain 1% then multiply by 100 to obtain original price.

original price = $17.85 × $\frac{100}{85}$ = $21

a) 3(-2) + 4(3) = -6 + 12 = 6

b) 2(-2) -3(3) +5 = -4 -9 + 5 = -8

c) 4(-2) -(3) = -8 -3 = -11

d) -(-2) -2(3) = 4 -6 = -2

e) (1/2)(-2) +(3) = -1 +3 = 2

f) (2/3)(3) -(1/2)(-2) = 2 + 1 = 3

What is lim x→-3 sqrt x^2-8

vitfil [10]

If the -8 is under the square root, then...

$\displaystyle L = \lim_{x\to -3} \sqrt{x^2-8}\\\\L = \sqrt{(-3)^2-8}\\\\L = \sqrt{9-8}\\\\L = \sqrt{1}\\\\L = 1\\\\$

If the -8 is not under the square root, then...

$\displaystyle L = \lim_{x\to -3} \sqrt{x^2}-8\\\\L = \sqrt{(-3)^2}-8\\\\L = \sqrt{9}-8\\\\L = 3-8\\\\L = -5$

Either way, we replace x with -3 and simplify.

For more information, refer to the direct substitution rule for limits.
