The distance between two points knowing theirs coordinates:

AB =√[(x₂-x₁)² +(y₂-y₁)²]; ===>C(-4,3) & D(1,0) Given
                                                C(x₁,y₁) & D(x₂,y₂)

AB =√[(1-(-4))²+(0-3)²] =√(34) = 5.381 ≈ 5.83 units

Answer:

The distance between two points knowing theirs coordinates:

AB =√[(x₂-x₁)² +(y₂-y₁)²]; ===>C(-4,3) & D(1,0) Given

                                               C(x₁,y₁) & D(x₂,y₂)

AB =√[(1-(-4))²+(0-3)²] =√(34) = 5.381 ≈ 5.83 units

Suppose that time spent on hold per call with customer service at a large telecom company is normally distributed with a mean µ
lana66690 [7]

Answer:

0.3108 is the probability that the sample mean is between 7.8 and 8.2 minutes.    

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 8 minutes

Standard Deviation, σ = 2.5 minutes

Sample size, n = 25

We are given that the distribution of  time spent is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

Standard error due to sampling =

=\dfrac{\sigma}{\sqrt{n}} = \dfrac{2.5}{\sqrt{25}} = 0.5

P(sample mean is between 7.8 and 8.2 minutes)

P(7.8 \leq x \leq 8.2)\\\\ = P(\displaystyle\frac{7.8 - 8}{0.5} \leq z \leq \displaystyle\frac{8.2-8}{0.5})\\\\ = P(-0.4 \leq z \leq 0.4})\\\\= P(z < 0.4) - P(z < -0.4)\\\\= 0.6554 -0.3446= 0.3108

0.3108 is the probability that the sample mean is between 7.8 and 8.2 minutes.
