Answer

9 - 2x

Step-by-step explanation:

since there is no equal symbol in this equation, you can only simplify it.

20-2x-11

first combine like terms:

(20-11)-2x

then subtract 11 from 20, this will give you 20-2x-11 in its simplest form.

9 - 2x\\

10. A small plane was scheduled to fly from Atlanta to Washington, D.C. The plane flies at a constant speed of 230 miles per
MatroZZZ [7]

Answer:  The plane had traveled about 264 miles before turning back. The average speed was 230 mph

Step-by-step explanation: 230 - 10 = 220 speed outgoing

230+10 = 240 speed returning  

Average speed (220+240)÷2= 460/2 =230 mph (needless to calculate!) Multiplied by total time 2.3 hours = 529 miles total distance.

Traveling the entire distance at 220mph would take about 2.4 hours. Traveling the entire distance at 240mph would take about 2.2 hours, a difference of .20 hours. Cut those times in half:

Traveling at 220mph for 1.2 hours would cover about 264 miles.

Traveling at 240mph for 1.1 hours would cover about 264 miles.

It adds up to 528 miles. The plane can't turn instantly, so figure the turn took the missing mile!

An optical inspection system is used to distinguish among different part types. The probability of a correct classification of a
Whitepunk [10]

Answer: \mu=2.88\ \&\ \sigma^2=0.115

Step-by-step explanation:

Given : The probability of a correct classification of any part is : p=0.96

sample size : n= 3

The formula to find the mean and variance for binomial distribution is given by :-

\mu=np\\\\\sigma^2=np(1-p)

Let the random variable X denote the number of parts that are correctly classified.

The, for the given situation, we have

\mu=3(0.96)=2.88\\\\\sigma^2=(3)(0.96)(1-0.96)=0.1152\approx0.115

Hence, the mean and variance of X are 2.88 and 0.115 respectively.
