<h2><em>8</em><em>7</em><em>.</em><em>9</em><em>2</em></h2>

<em>Given,</em>

<em>a</em><em>=</em><em>4</em>

<em>b</em><em>=</em><em>3</em>

<em>Nowz</em>

<em>3.14( {a}^{2}  + ab) \\  = 3.14( {4}^{2}  + 4 \times 3) \\  = 3.14(16 + 12) \\  = 3.14 \times 28 \\  = 87.92</em>

In a recent​ year, an author wrote 169 checks. Use the Poisson distribution to find the probability​ that, on a randomly selecte
grigory [225]
We should first calculate the average number of checks he wrote per day.  To do that, divide 169 by 365 (the number of days in a year) and you get (rounded) 0.463.  This will be λ in our Poisson distribution.  Our formula is
P(X=k)= \frac{ \lambda ^{k}-e^{-\lambda} }{k!}.  We want to evaluate this formula for X≥1, so first we must evaluate our case at k=0.  
P(X=0)= \frac{0.463 ^{0}-e ^{-0.463} }{0!} \\ = \frac{1-e ^{-0.463} }{1} =0.3706
To find P(X≥1), we find 1-P(X<1).  Since the author cannot write a negative number of checks, this means we are finding 1-P(X=0).  Therefore we have 1-0.3706=0.6294.
There is a 63% chance that the author will write a check on any given day in the year.<em />

In a triangle ,Angle B is twice as large as Angle A.Angle C is five more than Angle B. What are the angle measurements of Angles
777dan777 [17]

Answer:

∠ A = 35°, ∠ B = 70°, ∠ C = 75°

Step-by-step explanation:

let ∠ A be x then ∠ B is 2x ( twice as large as A ) and

∠ C is 2x + 5 ( 5 more than B )

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180

x + 2x + 2x + 5 = 180, that is

5x + 5 = 180 ( subtract 5 from both sides )

5x = 175 ( divide both sides by 5 )

x = 35

Thus

∠ A = x = 35°

∠ B = 2x = 2 × 35° = 70°

∠ C = 2x + 5 = 70 + 5 = 75°
