Answer:

NVU =150

Step-by-step explanation:

WVN + NVU = WVU

We know NVU = 2x+150 and WVU = x+176 and WVN = 26

Substituting these in

26+ 2x+150 = x+176

Combine like terms

176+2x= x+176

Subtract 176 from each side

176-176+2x= x+176-176

2x=x

Subtract x from each side

2x-x = x-x

x=0

NVU = 2x+150

0+150

NVU =150

m∠WVU = m∠NVU + m∠WVN

We have m∠WVU = x + 176, m∠NVU = 2x + 150 and m∠WVN = 26°. Substitute:

x + 176 = (2x + 150) + 26

x + 176 = 2x + (150 + 26)

x + 176 = 2x + 176 <em>subtract 176 from both sides</em>

x = 2x <em>subtract x from both sides</em>

0 = x

m∠NVU = 2x + 150 → m∠NVU = 2(0) + 150 = 0 + 150 = 150

Answer: m∠NVU = 150°

A Starbucks coffee shop serves an average of 3500 customers per day, with a standard deviation of 250. What is the probability t

castortr0y [4]

Answer:

$P(3300$

And we can find this probability with this difference:

$P(-0.8$

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Solution to the problem

Let X the random variable that represent the amount of cofee shops of a population, and for this case we know the distribution for X is given by:

$X \sim N(3500,250)$
