Happy Holidays!

We can use the following equation to calculate uniform acceleration:

\large\boxed{a = \frac{\Delta v}{\Delta t} = \frac{v_f - v_i}{\Delta t}}}

Plug in the given values to solve:

\frac{85 - 65}{16}}} = \frac{20}{16} = \boxed{1.25 m/s^2}}

An airline is planning its staffing needs for the next year. If a new route is​ approved, it will hire 858 new employees. If a n
stealth61 [152]

Answer:

E(X) = \sum_{i=1}^n X_i P(X_i)

And from the problem we know the following:

P(X_1) = 0.34 , X_1 =858 represent the condition if the route is approved

P(X_2) = 1-0.34=0.66 , X_1 =157 represent the condition if the route is NOT approved

Then replacing in the formula for the expected value we got:

E(X) = 858*0.34 + 157*0.66 = 395.34

So then the expected number of new employees to be hired by the​ airline based on the conditions given is between 395 and 396.

Step-by-step explanation:

For this cae we can define the random variable X who represent the number of new employees to be hired by the​ airline and we can find the expected value with the following general formula:

E(X) = \sum_{i=1}^n X_i P(X_i)

And from the problem we know the following:

P(X_1) = 0.34 , X_1 =858 represent the condition if the route is approved

P(X_2) = 1-0.34=0.66 , X_1 =157 represent the condition if the route is NOT approved

Then replacing in the formula for the expected value we got:

E(X) = 858*0.34 + 157*0.66 = 395.34

So then the expected number of new employees to be hired by the​ airline based on the conditions given is between 395 and 396.

Use the unique factorization theorem to write the integer in standard factored form.<br><br> 1.5400
mash [69]

Answer:

Standard factor form of the integer : 15400 = 2³ × 5² × 7 × 11

Step-by-step explanation:

According to the unique factorization theorem, a given integer n (where, n>1), either is a prime number or can be represented as the product of the prime numbers.

Firstly, it is checked that the given integer is divisible by the smallest prime number 2 . If the integer is not divisible by 2, then the integer is checked for the next prime number 3 and then checked for 5 and so on until the remaining integers are prime numbers.

So, the standard factored form of the integer:

15400 = 2 × 770

15400 = 2 × 2 × 3850

15400 = 2 × 2 × 2 × 1925

15400 = 2 × 2 × 2 × 5 × 385

15400 = 2 × 2 × 2 × 5 × 5 × 77

15400 = 2 × 2 × 2 × 5 × 5 × 7 × 11

or,

15400 = 2³ × 5² × 7 × 11

Therefore, the standard factor form of the integer: 15400 = 2³ × 5² × 7 ×11
