Answer:

0.000024

Step-by-step explanation:

If the first player gets exactly five hearts, there are 39 cards left, 8 of which are hearts.

So, the probability of getting one heart is 8/39, for the second heart the probability is 7/38 and 6/37 and 5/36 for the 3rd and 4th hearts.

There are still 4 hearts in the deck, and the probability of getting a non heart is (35-4)/35=31/35, (34-4)/34=30/34,..., (27-4)/27=23/27 for the next 9 cards.

<em>As the event of taking a card is independent of the previous result</em>, the probability the second player gets exactly 4 hearts is

(8/39)*(7/38)*(6/37)*(5/36)*(31/35)*(30/34)***(23/27)

= 0.000024

an artificial lake is in the shape of a rectangle and has an area of 9/20 square mile. the width of the lake is 1/5 the length o
Gnom [1K]
X=length
y=width
Area (rectangle)=length x width
we suggest this system of  equations:
y=x/5
xy=9/20
solve this system of equations by substitution method:
x(x/5)=9/20
x²/5=9/20
Least common multiple=20
4x²=9
x²=9/4
x=⁺₋√(9/4)
we have two solutions:
x₁=-3/2   it does not validate
x₂=3/2    ⇒y=x/5=(3/2)/5=3/10

The dimensions of the lake are:
lengh=3/2 miles
width=3/10 miles

to check:
Area=3/2 miles x 3/10 miles=9/20 miles².
width is 1/5 the length of the lake ⇒  3/10 miles=(3/2) /5 miles

What is the solution to equation 8-2x+6=24
ki77a [65]

8 - 2x + 6 = 24

(8 + 6) - 2x = 24

14 - 2x = 24       <em>subtract 14 from both sides</em>

-2x = 10       <em>divide both sides by (-2)</em>

<h3>x = -5</h3>

user100 [1]

Answer:

Equations:

<u>Mia: 10 + 10x = y</u>

<u>Julie: 100 - 5x = y</u>

Solved: <u>(6, 70)</u>

Step-by-step explanation:

Mia: 10 + 10x = y

She already has 10 (<u>10</u>) and gains 10 (<u>+10</u>) per day (<u>x</u>). Total is y gained.

Julie: 100 - 5x = y

She already has 100 (<u>100</u>) and loses 5 (<u>-5</u>) per day (<u>x</u>). Total is y gained.

Then I simply solve

10 + 10x = y

100 - 5x = y

Resulting in (6, 70)
