Answer:

[4 + 1] x [7 - 2] = 25

Step-by-step explanation:

When you have the brackets around [4 + 1], you add them up to get 5. You then do [7 - 2] to get 5. Once you multiply 5x5, you get 25. Hope this helps! :)

Answer:

[4 + 1] *[7-2] =25

Step-by-step explanation:

[4 + 1] *[7-2] =25

We need to get to 25

What makes 25

5*5

4+1 =5

7-2 =5

5*5 =25

So we need brackets around 4+1 and around 7-2

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 $\left.11.04\right)$ .

The curves cross at coordinates (x, y) = (1, 4). The x-value is said to represent the increase in temperature, while the y-value is said to represent the numbers of visitors and those and who leave early.

The "solution" is the temperature change at which the number of visitors is equal to the number who leave early.
