Answer:

45.6 ft

Step-by-step explanation:

The room is a rectangle. The perimeter of a rectangle is

perimeter = 2L + 2W

perimeter = 2(12.62 ft) + 2(10.2 ft)

perimeter = 25.24 ft + 20.4 ft

perimeter = 45.64 ft

Since 10.2 ft has only 3 significant digits, the answer must also have only 3 significant digits.

Answer: perimeter = 45.6 ft

Melissa, Dan, and Henry have $87 in their wallets. Dan has 3 times what Henry has. Melissa has $8 less than Henry. How much does
puteri [66]

Answer:

Henry has $19, Dan has $57, and Melissa has $11

Step-by-step explanation:

Let x represent how much money Henry has

Since Dan has 3 times what Henry has, his amount is 3x

Since Melissa has $8 less than Henry, her amount is x - 8

Create an equation that sets these 3 values equal to 87, then solve for x

(x) + (3x) + (x - 8) = 87

5x - 8 = 87

5x = 95

x = 19

So, Henry has $19

Find how much Dan has by multiplying 19 by 3

19(3)

= 57

Find how much Melissa has by subtracting 8 from 19

19 - 8

= 11

So, Henry has $19, Dan has $57, and Melissa has $11

The value of a car x years from now is given by v(x) = 2000(0.75)x. What is the annual compound interest rate of depreciation?
patriot [66]
Hello! So because the value in the parenthesis is less than one, this represents exponential decay. 0.75 is 75% in decimal form. Percents are parts of 100. let's multiply that number from 100. 100 - 75 is 25. There. The rate of depreciation is 25%.

anygoal [31]

Answer:

Nominal, Ordinal, interval or Ratio scale, Nominal.

Step-by-step explanation:

In Statistics, we can assort qualitative variables as nominal, for non-numerical values (Good, Yes, Man, Woman, Excellent, Tall, etc.). For numerical ones, we can rank them orderly, id est, ordinal (1st, 2nd, 3rd, 4th, etc.). Moreover, we can also categorize some numerical variables as an interval or ratio scale (90º F, 6' 2'' etc.).

Examining each one:

1. Would your overall rating of this tour be excellent, good, fair, or poor? <u>Nominal. </u>

These are not numerical. These are qualitative classification.

2. How many escorted vacations have you taken prior to this one?

<u>Ordinal</u>. The 1st, 2nd, 3rd, etc.

3. What is the current temperature outside? <u>Interval or Ratio Scale</u>

This is a classic Interval classification example. Since the temperature is graded in intervals then this an Interval.

4. Do you feel that the stay in New York was sufficiently long? Nominal.

Another non-numerical classification
