In a bag, there are only black pins, green pins, pink pins and white pins

Mathematics
1 answer:
kozerog [31]3 years ago
6 0

Answer:

P of white: 0.26

P of green: 0.39

Step-by-step explanation:

Assume the probability of a white pin is p.

Then the probability of a green pin is (3/2)p because their ratio is 3:2.

The sum of the probabilities must be 1.

0.1+(3/2)p+0.25+p=1

(5/2)p+0.35=1

(5/2)p=0.65

p=(2/5)(0.65)=0.26

(3/2)p=0.39

If the bottom row as a result of sythetic division is 1 3 0 4 0, then the quotient is which of the following? Select one:
zmey [24]

The quotient of the synthetic division is x^3 + 3x^2 + 4

<h3>How to determine the quotient?</h3>

The bottom row of synthetic division given as:

1 3 0 4 0

The last digit represents the remainder, while the other represents the quotient.

So, we have:

Quotient = 1 3 0 4

Introduce the variables

Quotient = 1x^3 + 3x^2 + 0x + 4

Evaluate

Quotient = x^3 + 3x^2 + 4

Hence, the quotient of the synthetic division is x^3 + 3x^2 + 4

9. Solve for x,<br>9x - 25<br>5x + 7<br>N​
kati45 [8]

Answer:

x = 8

Step-by-step explanation:

Simplifying

9x + -25 = 5x + 7

Reorder the terms:

-25 + 9x = 5x + 7

Reorder the terms:

-25 + 9x = 7 + 5x

Solving

-25 + 9x = 7 + 5x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-5x' to each side of the equation.

-25 + 9x + -5x = 7 + 5x + -5x

Combine like terms: 9x + -5x = 4x

-25 + 4x = 7 + 5x + -5x

Combine like terms: 5x + -5x = 0

-25 + 4x = 7 + 0

-25 + 4x = 7

Add '25' to each side of the equation.

-25 + 25 + 4x = 7 + 25

Combine like terms: -25 + 25 = 0

0 + 4x = 7 + 25

4x = 7 + 25

Combine like terms: 7 + 25 = 32

4x = 32

Divide each side by '4'.

x = 8

Simplifying

x = 8
