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
Answer:
Just took the test :))
Step-by-step explanation:
Look at the image down below!! ヽ(o^▽^o)ノ
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>

Taking "2099" as common term, we get,

On solving brackets,

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