Answer: a^2+3a+2

Step-by-step explanation:

if you do the distribution method and do (a*a)+(a*2)+(1+a)+(1*2)=(a^2)+(2a)+(a)+(2)

which you get a^2+3a+2

Answer:

Step-by-step explanation:

There are <u>6</u><u> different shapes</u>

You want the outcome to be a Nonagon

You put the outcome as a ratio 1/6

1/6=0.1666667

0.1666667*100=16.6667%

The exponential probability distribution is a discrete distribution that is often used to describe time between customer arrival
n200080 [17]

Answer:

True

Step-by-step explanation:

The time between customer arrivals is called inter-arrival time. According to Queueing Notation, the inter-arrival time can be model based on difference probability distribution. The probability distribution by which the inter-arrival time can be modeled include:

  • Exponential Distribution or Markov distribution
  • Constant or Deterministic
  • Hyper - exponential
  • Arbitrary or General distribution

For a moving object, the force acting on the object varies directly with the objects acceleration. When a force of 35 N acts on
Genrish500 [490]
<h3>Answer:  3 m/s^2</h3>

=======================================================

According to Newton's Second Law, we know that

F = m*a

where F is the force applied, m is the mass and 'a' is the acceleration.

We see that this is a direct variation equation for F and a, such that m is the constant of variation. It's similar to how y = kx is also a direct variation equation.

Plug in F = 35 and a = 5 to find m

F = ma

35 = m*5

35/5 = m

7 = m

m = 7

The object has a mass of 7 kg

Our equation F = ma updates to F = 7a

Now plug in the force F = 21 to find 'a'

F = 7a

21 = 7a

21/7 = a

3 = a

a = 3

The acceleration will be 3 m/s^2

Notice how a smaller force applied means that the acceleration has also gone down as well.
