What is the probability that either two heads or three heads will be thrown if six fair coins are tossed at once?
lesantik [10]

Answer:The right answer will be

0. 546875

Step-by-step explanation:

When 6 coins are tossed , the total number of outcomes is 2*2*2*2*2*2= 64

The number of ways of getting two heads are 6!/2!*4!=15.

The probability of getting two heads P(A) is 15/64 .

In the same way, the probability of getting three heads P( B) is 5/16.

Now, P(A)+P(B)= 0.546875

What is the total cost of a $2,099 couch including the 6.5% sales tax​
3241004551 [841]

The total cost of a $2,099 couch including the 6.5% sales tax​ is $ 2235.435

<u>Solution:</u>

Given that,

cost of couch = $ 2099

Sales tax = 6.5%

<em><u>Finding the total cost of couch with sales tax:</u></em>

Total cost of couch = selling price of couch + sales tax on the selling price of couch

Plugging in values we get,

<em>Total cost of couch = $ 2,099 + 6.5% sales tax on $ 2099</em>

\text { Total cost of couch }=2099+\frac{6.5}{100} \times 2099

Taking "2099" as common term, we get,

\text { Total cost of couch }=2099\left(1+\frac{6.5}{100}\right)

On solving brackets,

\text { Total cost of couch }=2099 \times 1.065=2235.435

Hence, the total cost of the couch is found as $ 2235.435

The point (-4‚-2) lies on a circle. What is the length of the radius of this circle if the center is located at (-8‚-10)
MAVERICK [17]

Answer:

<em>4√5</em>

Step-by-step explanation:

The length of the radius of the circle will be the distance between the two coordinates. Using the formula:

D = √(x₂-x₁)²+(y₂-y₁)²

Given the coordinates (-4‚-2) and (-8‚-10)

R = √(-8-(-4))²+(-10-(-2))²

R = √(-4)²+(-8)²

R = √16+64

R = √80

R = √16*5

R = 4√5

<em>Hence the  length of the radius of this circle is 4√5</em>
