57/69 =19/23   divide by 3
9/28   = 9/28     same
22/44  = 1/2       divide by 22
1.125  =  1  125/1000  divide 25 = 1 5/40 or 1 1/8

52 regular playing cards are randomly dealt to four players with each players receiving 13 cards. What is the probability that e
Vadim26 [7]

Answer:

The probability is 1/28,561

Step-by-step explanation:

Here, we want to find the probability that each of the players will receive exactly one ace.

In a deck of cards, we have 4 suites of 13 cards each, with each of the suites consisting of 1 ace.

So, the probability of getting an ace for each of the four players will be 4/52 = 1/13

Now, the probability of each of the players getting exactly one ace will be; first got one ace , second got one , third got one and fourth got one.

mathematically, this probability will be 1/13 * 1/13 * 1/13 * 1/13 = (1/13)^4 = 1/28,561

Find the equation of the line that is perpendicular to the line
ddd [48]

Answer:

y=-x+16

Step-by-step explanation:

Hi there!

<u>What we need to know:</u>

  • Linear equations are typically organized in slope-intercept form: y=mx+b where m is the slope and b is the y-intercept (the value of y when x is 0)
  • Perpendicular lines always have slopes that are negative reciprocals (ex. 3 and -1/3, 5/6 and -6/5, etc.)

<u>1) Determine the slope (m)</u>

y=x-9

Rewrite the equation

y=1x-9

Now, we can identify clearly that the slope of the line is 1. The negative reciprocal of 1 is -1, so therefore, the slope of a perpendicular line would be -1. Plug this into y=mx+b:

y=-1x+b\\y=-x+b

<u />

<u>2) Determine the y-intercept (b)</u>

y=-x+b

Plug in the given point (7,9) and solve for b

9=-7+b

Add 7 to both sides to isolate b

9+7=-7+b+7\\16=b

Therefore, the y-intercept is 16. Plug this back into y=-x+b:

y=-x+16

I hope this helps!

Suppose Brandi buys a CD for $1000 that earns 3% APR and is compounded
Dovator [93]

Answer:

$1,061.76

Step-by-step explanation:

(refer to attached handout)

For compound interest, you are given:

A = ? (need to find)

P = $1000

r = 3% = 0.03

n = compounded monthly = 12 times per year

t = 2 years

(substituting this into the formula)

A = P [  1 + (r/n) ] ^(nt)

A = 1000 [  1 + (0.03/12) ] ^[(12)(2)]

A = 1000 [  1 + 0.0025 ] ^24

A = 1000 [  1.0025 ] ^24

A = 1,061.76
