Total number of marbles = 10

Total number of marbles that has a factor of 3 = 3
They are {3, 6, 9)

P(factor of 3 ) = 3/10

Total number of marbles that is a prime number = 4
They are {2, 3, 5, 7}

P(Prime Number) = 4/10 = 2/5

Total number of marbles that is even: 5
They are {2, 4, 6, 8, 10}

P(even) = 5/10 = 1/2

Total number of marbles that is divisible by 13 = 0

P(divisible by 13) = 0/10 = 0

Factor of 3 = 3/10
Prime = 1/2
Even = 1/2
Evenly divisible by 13 = no chance

Which graph represents the solution set for the quadratic inequality x2 + 2x + 1 > 0
AnnyKZ [126]

we have

x^{2}+2x + 1 > 0

we know that

x^{2}+2x+1=(x+1)^{2}

so

(x+1)^{2}> 0

two solutions

<u>first solution </u>

(x+1)> 0

x > -1

the first solution is the interval---------> (-1,∞)

<u>second solution</u>

-(x+1)> 0

-x-1> 0

-x> 1

x< -1

the second solution is the interval---------> (-∞,-1)

therefore

the solution is all real numbers except the number -1

the answer in the attached figure

If someone could help! ​
ad-work [718]

Step-by-step explanation:

This time round, use SOH method (Sin angle = Opposite/Hypotenuse)

given Opposite = 7

Hypotenuse = 10

\sin(x)  =  \frac{opposite}{hypotenuse}  \\  \sin(x)  =  \frac{7}{10}  \\ x =  {sin}^{ - 1} ( \frac{7}{10} ) \\  = 44.4deg(nearest \: tenth)
