Answer:

200

Step-by-step explanation:

Given:The dealership surveys 50 random customers and finds that 25 shoppers can spend $10,000 or less, 15 can spend $10,001 to $25,000, and 10 can spend more than $25,000.

To Find:  If 1000 customers visit the dealership this coming weekend, the number of customers having budget greater than $25000.

Solution:

Total Number of surveyed customers=50

The Number of customers that can spend \$ 10000=25

The Number of customers that can spend \$ 10001 to \$ 25000=15

The Number of customers that can spend more than \$ 25000=10

Percentage of people that can spend more than \$ 25000 = Number of customers that can spend more than \$ 25000\setminus Total Surveyed Customers

                                    \left ( 10\setminus 50 \right )\times 100=20%

If 1000 customers visits the dealership,

customer that have budget greater than [\$ 25000= total visiting customers\times percentage of people that can spend more than \$ 25000

                                    1000\times 20\setminus 100

                                    200

Hence the customers that having budget greater than \$ 25000 will be 200

Jlenok [28]

Answer:

Todd's Z-score is - 0.27    

Step-by-step explanation:

<u><em>Explanation</em></u>:-

<u><em>Step(i)</em></u>:-

Given data A test is normally distributed with a mean of 70 and a standard deviation of 10.

<em>Mean of the population 'μ' = 70 </em>

<em>Standard deviation of the Population ' σ ' = 10</em>

<em>let 'x' be the random variable in normally distributed</em>

<u><em>Step(ii)</em></u>:-

<em>Given raw score  'x' = 55</em>

Todd's Z-score

                      Z = \frac{x-mean}{S.D}

                     Z = \frac{55-70}{55}

                     Z = -0.27

<u><em>Final answer</em></u>:-

<em>Todd's Z-score is - 0.27        </em>

Solve the following equation: 5n+34=−2(1−7n). Write descriptive steps using vocabulary and mathematical reasoning explaining how
Agata [3.3K]

Answer:   4 = n

Step-by-step explanation:

5n + 34 = -2(1-7n)

Distribute negative 2 to both 1 and negative 7n. You do this first due to the rules of PEMDAS

5n + 34 = -2 + 14n

Add two to both sides of the equation in order to further isolate (n) in 14.

5n + 36 = 14n

Subtract 5n from both sides of the equation so that the values with (n) are on one side of the equation.

36 = 9n

Divide nine from 36 and 9n in order to isolate (n).

4 = n

This then gives you your final answer.
