Answer:

Step-by-step explanation:

y = -3x - 3

m = -3_______

b = -3________

y = 2x + 2

m = 2_______

b = _2_______

SOLVE NOW : -3x - 3 = 2x + 2

- 5x = 5

x = -1

subst in y : y = 2(-1)+2 = 0

the solution is : ( - 1 , 0 )

y = -3x- 3 an equation for the line 'red'

y = 2x+2 an equation for the line 'bleus'

Hi, this is correct because repeating decimals are rational numbers.

Rational numbers can be written by a fraction of integers.

A light bulb factory produces 922 light bulbs every hour. Approximately 3.34% of the light bulbs are defective, and do not work.

Nikitich [7]

Answer:

The value is $\sigma = 5.46$

Step-by-step explanation:

From the question we are told that

The number of light produced in an hour is n = 922

The proportion of the bulb that are defective is p = 0.0334

Generally given from the question that we should use binomial distribution it then means that the standard deviation is mathematically evaluated as

$\sigma = \sqrt{ n * p (1-p)}$

=> $\sigma = \sqrt{ 922 * 0.0334 * (1-0.0334)}$

=> $\sigma = 5.46$
