Serhud [2]

Answer:

$2x^5+3x^4$

Step-by-step explanation:

$x^3\left(2x^2+3x\right)$

Apply distributive law: $a\left(b+c\right)=ab+ac$

$x^3\left(2x^2+3x\right)=x^3\times \:2x^2+x^3\times \:3x$

$x^3\times \:2x^2+x^3\times \:3x$

$2x^5+3x^4$

A pretzel company calculated that there is a mean of 75.4 broken pretzels in each production run with a standard deviation of 5.

Snowcat [4.5K]

Answer:

P [ Z < 66 ] = 35,15 %

Step-by-step explanation:

Normal Distribution

Population mean μ₀ = 75,4

Standard deviation σ = 5,2

Then:

P [ Z < 66 ] = ( 66 - 75,4 ) / 5,2

P [ Z < 66 ] = - 9,4 / 5,2

P [ Z < 66 ] = - 1,81

In z-table we look for the reciprocate area for that z score and find

P [ Z < 66 ] = 0,3515

P [ Z < 66 ] = 35,15 %
