Let x be one angle and x +28 be the second angle. X + x+ 28=90 2x = 62 X=31, x+ 28=59 So 31 & 59 are the angles

Question 6(Multiple Choice Worth 5 points)

ankoles [38]

Answer:

Product 3

Step-by-step explanation:

You can easily find it out based on the last column (Year 3)... where product 3 has the highest market value.

This is very logical due to exponential nature of the price evolution function... it might start lower than most of the other products, but it will grow at a much faster rate... so much that in second year, it's already tie for the most market value.

In year 3, the difference is obvious and it would be even bigger in the following years.

Distributive property
12-3x-13 = 0
Combine like terms
-1-3x = 0
-3x = 1
Divide by -3
x = -1/3

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.
