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 $\left.11.04\right)$ .

$6y - y = 5y$
$5y = 210$
$\frac{210}{5}$

Find the value of x that makes lines u and v parallel. 11x-2 is the "larger" looking angle on the left.

max2010maxim [7]

Answer: 12

11x - 2 = 130

11x = 130 + 2

11x = 132

x = 132/11

x = 12

Now with value x the angle will be 130 and using converse of corresponding angles theorem line v and u will be parallel
