Answer:

$\frac{1}{2}$

Step-by-step explanation:

In a 6 sided die, the numbers that are possible to be rolled are

1, 2, 3, 4, 5, and 6.

We know that the numbers 2, 3, and 5 are prime, while 1, 4, and 6 are not.

3 out of the 6 numbers are prime, therefore 3 out of the 6 numbers are not prime.

So the fraction is $\frac{3}{6}$

This simplifies to $\frac{1}{2}$ .

Hope this helped!

Answer:

1/2

Step-by-step explanation:

the prime numbers between 1 and 6 inclusive are: 2, 3, 5 (i.e 3 possible outcomes)

the non prime numbers are : 1, 4 and 6 (i.e 3 possible outcomes)

for each roll, the total number of possible outcomes is 6 (because its a 6-sided die)

P(does not roll a prime number) = P (rolls 1, 4 or 6)

= number of possible non-prime outcomes / total number of outcomes

= 3/6

= 1/2

A certain circle can be represented by the following equation. x^2+y^2+18x+14y+105=0 What is the center of the circle? What is t

Gre4nikov [31]

Answer:

See below.

Step-by-step explanation:

Recall the equation for a circle:

$(x-h)^2+(y-k)^2=r^2$ , where (h,k) is the center and r is the radius.

We need to turn the given equation into the above format. We do this by completing the square.

First, group them:

$(x^2+18x)+(y^2+14y)=-105$

For the first section, complete the square for $x^2+18x$ :

$x^2+18x+81-81$

$(x+9)^2-81$

Do the same for the second:

$y^2+14y$

$y^2+14y+49-49$

$(y+7)^2-49$

All together:

$((x+9)^2-81)+((y+7)^2-49)=-105$

$(x+9)^2+(y+7)^2-130=-105$

$(x+9)^2+(y+7)^2=25$

The center is (-9,-7).

The radius is $\sqrt{25}=5$

Answer:

<h2><u>I can do algebra forever</u></h2>

First we can use distributive property. 2a-10 = 6. So we add 10 on both sides and get 2a=16. Then we divide both sides by 2 so we get a = 8. Therefore proved algebraically that a = 8. I can always do algebra. Feel free to keep asking questions like these. Well feel free to ask any question because this is brainly.

<h2><u>Answer is a = 8, 8 is answer</u></h2><h2><u></u></h2>

The area of the smallest equilateral triangle with one vertex on each of the sides of the right triangle with side lengths and <

Gre4nikov [31]

Set up the given triangle on x-y coordinates with right angle at (0,0). So the two vertices are at (5,0) and (0,2 $sqrt{x} n]{3}$ )

let (a,0) and (0,b) be two vertices of the<span> equilateral triangle. So the third vertex must be at </span> $(\frac{a+\sqrt{3}b}{2} , \frac{b+\sqrt{3}a}{2} )$

for a pt (x,y) on line sx+ty=1, the minimum of $\sqrt{x^{2} + {y^{2} }$
equals to $\frac{1}{ \sqrt{ s^{2} + t^{2} } }$

smallest value happens at $\frac{10 \sqrt{3} }{67}$

so area is $\frac{75\sqrt{3}}{67}$

hence m=75, n=67, p=3
m+n+p = 75+67+3 = 145

salantis [7]

Hello u,
on monday⇒25pants
tuesday⇒37pants
u agree that there is an increase in sail from monday to tuesday.this increase is calculated as follows,
%increase=[(number of pants sold on tuesday-pants sold on monday)/number of pants sold on monday]*100=48%

goodluck
