18/60 which is equal to 3/10

So you just need to put it into proportions which is blue to total. The total is 60 and there is 18 blue. Then you only need to simplify.

Change or chance?

To find the probability/chance of getting the blue marbles is:-

probability = \frac{number \: of \: blue \: marbles}{total \: of \: all \: marbles}

From the question, we have:-
Number of blue marbles : 18
Total of all marbles : 32 + 18 + 10 = 60

Thus,
probability = \frac{18}{60} \\ probability = \frac{3}{10}

What are the solutions to 2x^2+7y=4 ? Select all that apply.
liberstina [14]

Answer:

x = -1/2 , 4

Step-by-step explanation:

1) If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.

2x+1=0

x−4=0

2) Set the first factor equal to 0.

2x+1=0

3) Subtract 1 from both sides of the equation.

2x=−1

4) Divide each term by 2 and simplify.

2x/2= −1/2

5) Cancel the common factor of 2.

x= −1/2

6) Move the negative in front of the fraction.

x = −1/2

7) Set the next factor equal to 0 and solve.

x=4

8) The final solution is all the values that make

(2x+1)(x−4) = 0 true.

9) x = −1/2 , 4

What are the zeroes of P(x) = x3 – 6x2 - x +62​
Maurinko [17]

Answer:

x = 6

x = -1

x = 1

Step-by-step explanation:

Given:

Correct equation;

P(x) = x³ - 6x² - x + 6

Computation:

x³ - 6x² - x + 6

x²(x-6)-1(x-6)

(x-6)(x²-1)

we know that;

a²-b² = (a+b)(a-b)

So,

(x-6)(x²-1)

(x-6)(x+1)(x-1)

So,

zeroes are;

x = 6

x = -1

x = 1
