To factor this expression, the first thing to do is to take out the terms and look at the factors of each one:
-5p:-1*5*p
20: 2*2*5

When you look at the factors for each term, notice that both the terms have the same greatest common factor of 5. Noticing this, factor out 5 from the expression which will get you to 5(-p+4). However, normally in math, the first term of an expression usually is not a negative so you would factor out -1 from the expression which would result in your answer: -5(p-4)

A paint machine dispenses dye into paint cans to create different shades of paint. The amount of dye dispensed into a can is kno
Ket [755]

Answer:

0.9115 is the proportion of paint cans that contain less than 5.54 ml of the dye.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 5 ml

Standard Deviation, σ = 0.4 ml

We are given that the distribution of amount of dye dispensed is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

P(paint cans contain less than 5.54 ml of the dye)

P( x < 5.54) = P( z < \displaystyle\frac{5.54 - 5}{0.4}) = P(z < 1.35)

Calculation the value from standard normal z table, we have,  

P(x < 5.54) =0.9115 = 91.15\%

0.9115 is the proportion of paint cans that contain less than 5.54 ml of the dye.
