Two cards are drawn from a standard 52-card deck, without replacement. Find the probability that they are both aces.

Delvig [45]

4 aces in a deck = 4/52 = 1/13
then without replacement, 3 aces in 51 cards
so
1/13 * 3/51
= 3/663
= 1/221

answer
C.

The perimeter of a triangle is 93 ft. Side a of the triangle is twice as long as side b. Side c is 3 ft longer than side a. Find

Sunny_sXe [5.5K]

The length of side a is 36 feet and side b is 18 feet and side c is 39 feet

Solution:

Given that perimeter of triangle is 93 feet

The three sides of triangle are a, b, and c

Given that Side a of the triangle is twice as long as side b

side a = 2 times side b

a = 2b

$b = \frac{a}{2}$ ---- eqn 1

Given that Side c is 3 ft longer than side a

side c = 3 + side a

c = 3 + a ------ eqn 2

The perimeter of triangle is given as:

p = a + b + c

Where a, b, c are the length of sides of triangle

Substitute eqn 1 and eqn 2 in above formula

$p = a + \frac{a}{2} + 3 + a$

Given that perimeter = 93

$93 = a + \frac{a}{2} + 3 + a\\\\93 = \frac{2a + a + 6 + 2a}{2}\\\\93 \times 2 = 2a + a + 6 + 2a\\\\186 = 5a + 6\\\\5a = 186 - 6\\\\5a = 180\\\\a = 36$

Thus length of side a = 36 feet

Length of side b :

from eqn 1

$b = \frac{36}{2} = 18$

b = 18 feet

Length of side c:

From eqn 2,

c = 3 + 36 = 39

c = 39 feet

Thus length of side a is 36 feet and side b is 18 feet and side c is 39 feet

Please help with all, I’ll mark brainliest as long as you tell me how you got that answer.

Mumz [18]

Answer:

function= 2nd,6th

not a function=1st,3rd,4th,5th

Step-by-step explanation:

because in graphing a function, there should only be one y for the x. 2 or more y's in one x is considered as not a function
