Answer:

x=12

Step-by-step explanation:

we know that the sum of the angles in a triangle is 180 degrees

to find x we have to calculate the sum of the angles

(10x-11)+(3x-2)+(3x+1)=180

10x-11+3x-2+3x+1=180

16x-12=180

16x=180+12

16x=192

x=192/16=12

A new automated production process averages 1.4 breakdowns per day. Because of the cost associated with a breakdown, management

dalvyx [7]

Answer:

The required probability is 0.167

Step-by-step explanation:

Consider the provided information.

Let x be the number of breakdown per day.

A new automated production process averages 1.4 breakdowns per day.

λ=1.4

Probability of having three or more breakdowns during a day is:

$P(x\geq 3)=1-[f(0)+f(1)+f(2)]$

The Poisson probability function is: $f(x)=\frac{\lambda^xe^{-\lambda}}{x!}$

Therefore the required probability is:

$P(x\geq 3)=1-[\frac{\left(1.4^{0}e^{-1.4}\right)}{0!}+\frac{\left(1.4^{1}e^{-1.4}\right)}{1!}+\frac{\left(1.4^{2}e^{-1.4}\right)}{2!}]$

$P(x\geq 3)\approx1-0.833$

$P(x\geq 3)=0.167$

Hence, the required probability is 0.167

Conversions: 24,900 miles into meters (m) (1 inch =2.54cm)

Orlov [11]

For this, we will be using dimensional analysis as such:

$\frac{24900\ mi}{1}*\frac{5280\ ft}{1\ mi}*\frac{12\ in}{1\ ft}*\frac{2.54\ cm}{1\ in}*\frac{1\ m}{100\ cm}=\frac{4007266560}{100}=40072665.6\ m$

In short, 24,900 miles is 40,072,665.6 (40,072,666 if rounded to the whole meter) meters.
