An operations analyst counted the number of arrivals per minute at an ATM in each of 30 randomly chosen minutes. The results wer
liraira [26]

Step-by-step explanation:

since Poisson distribution parameter is not given so we have to estimate it from the sample data. The average number of of arrivals per minute at an ATM is

\hat{\lambda}=\bar{x}=\frac{\sum x}{n}=\frac{30}{30}=1

So probabaility for \mathrm{X}=1 is

P(X=1)=\frac{e^{-\lambda} \lambda^{x}}{x !}=\frac{e^{-1} \cdot 1^{1}}{1 !}=0.3679

So expected frequency for X=1 is 0.3679^{*} 30=11.037 (or \left.11.04\right) .

Vertex of y = −2(x−4)2 + 3<br> and identify it as a minimum or a maximum.
baherus [9]

An equation is formed of two equal expressions. The vertex of the equation y=-2(x-4)²+3 will lie at (4,3).

<h3>What is an equation?</h3>

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.


If we plot the graph of y=-2(x-4)²+3, then the vertex of the graph will lie at (4,3).

Hence, the vertex of the equation y=-2(x-4)²+3 will lie at (4,3).

A firework rocket is shot upward at a rate of 640ft/sec. Use the projectile formula h= -16t^2 +v0t to determine the times when t
mash [69]

Answer:

2 seconds and 38 seconds

Step-by-step explanation:

h=-16t²-vot

1,200=-16t²-640t

turn this into standard form

16t²-640t+1200=0

now plug thes numbers into the quadratice formula

a 16 b -640 c 1200

solve with quadratic formula to get ≅2 and ≅38 seconds

2/3x - 2 = 7 solve the equation
Kobotan [32]
Isolate the x.

Do the opposite of PEMDAS. Note the equal sign. What you do to one side, you do to the other.

2/3x - 2 = 7

Add 2 to both sides

2/3x - 2 (+2) = 7 (+2)

2/3x = 9

Multiply 3/2 to both sides to isolate the x

2/3x(3/2) = 9(3/2)

x = 9(3/2)

Multiply 9 with 3, and divide by 2

9 x 3 = 27
27/2 = 13.5

x = 13.5 is your answer

hope this helps
