Your firm wants to investigate how much money the typical tourist will spend on their next visit to New York. How many tourists
snow_lady [41]

Answer:  46

Step-by-step explanation:

Given : Margin of error : E= 17

Standard deviation : \sigma=70

Critical value for 90% confidence level :z_{\alpha/2}=1.645

Formula to find sample size is given by :-

n=(\dfrac{z_{\alpha/2}\times \sigma}{E})^2

i.e. n=(\dfrac{(1.645)\times 70}{17})^2

\Rightarrow\ n=45.880700692\approx46

Hence, the required minimum sample size = 46.

Using the data in the table, which statement is true?
Igoryamba

The true statement is mean > median

<h3>How to determine the true statement?</h3>

The mean is the average value.

So, we have

Mean = Sum/Count

This gives

Mean = (8 * 1 + 10 * 3 + 14 * 2)/(1 + 3 + 2)

Evaluate

Mean = 11

The mode is the measure with the highest frequency.

So, we have

Mode = 10

The median is the middle element

So, we have

Median = 10

The mean (11) is greater than the mode and the median

Hence, the true statement is mean > median

abruzzese [7]

Not sure about the weird echo in the question but I think we're being ask to evaluate

4 - 0.25g + 0.5h

when g=10, h=5

That's

4 - 0.25(10) + 0.5(5) = 4 - 2.5 + 2.5 = 4

Answer: 4

What is −1/2 − (−4/5) = x<br><br> Please Help Its due in like 15 minutes
laila [671]

Answer:

x = 3/10

Step-by-step explanation:

−1/2 − (−4/5) = x

First, switch sides.

x = −1/2 − (−4/5)

You are subtracting a negative number. Subtracting a negative number means add a positive number.

x = -1/2 + 4/5

Now you are adding two fractions, so you need a common denominator. The LCD of 2 and 5 is 10.

x = -5/10 + 8/10

x = 3/10
