Answer:

n = 1, 4

Step-by-step explanation:

Step 1: Write equation

n² - 5n + 4 = 0

Step 2: Solve for n

Factor: (n - 4)(n - 1) = 0

Find roots: n = 1, 4

Step 3: Check

Plug in n to verify if it's a solution.

1² - 5(1) + 4 = 0

1 - 5 + 4 = 0

-4 + 4 = 0

0 = 0

4² - 5(4) + 4 = 0

16 - 20 + 4 = 0

-4 + 4 = 0

0 = 0

If you solve by factoring this would be the process of it
Step 1: Factor left side of the the equation
(n-1)(n-4)=0
Step 2: set factors equal 0
n-1=0 or n-4=0
then you would solve both like a regular equation
n=1 or n=4 would be the answers

Mason plays a game by flipping two fair coins. He wins the game if both coins land facing heads up. If Mason plays 200 times, ho

aev [14]

Answer:

Total no.of possible outcomes = 200 × 4 = 800

No.of favourable outcomes = 200 × 1 = 200

P (E) = no.of favourable outcomes / total no.of possible outcomes

= 200/800

= 1/4

Kenzie makes quilts from blue and purple pieces of fabric. The diagram shows the ratio of blue pieces to

REY [17]

The purple pieces are 35 and total pieces is 32 if the Kenzie makes quilts from blue and purple pieces of fabric.

<h3>What is the ratio?</h3>

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

The question is incomplete.

The complete question is in the picture, please refer to the picture.

Total number of pieces = 3+5 = 8

So, the purple pieces = 5(5/8) = 35

Total pieces = 20/(5/8) = 4×8 = 32

Thus, the purple pieces are 35 and total pieces is 32 if the Kenzie makes quilts from blue and purple pieces of fabric.

How many solutions does the following system of equations have? y=5/2x+2 2y= 5x +4

goldfiish [28.3K]

Answer:

infinite solutions

Step-by-step explanation:

y=5/2x+2

2y= 5x +4

Multiply the first equation by 2

y = 5/2 x +2

2y = 5/2 *2 x +2 *2

2y = 5x +4

Since this is identical to the second equation (they are the same), the system of equations has infinite solutions
