Answer:

Sample mean = 6.25 hours per night.

Population mean = 5.5 hrs of sleep each night.

Step-by-step explanation:

A sample mean is the mean of the sample collected. The 25 students surveyed by the student is the sample. The average sleep time derived from the sample is the sample mean.

A population mean is the mean of all the population. Here the population are college students. The population mean is the mean derived from studying the sleep duration of all the population - college students

Answer:

1036

Step-by-step explanation:

Working each column from right to left

3 9 7 3

− 2 9 3 7

7 is greater than 3 so you must regroup:

Take 1 from 7, so 7 becomes 6.

Add 10 to 3, so 3 becomes 13.

6  13

 3 9 --

− 2 9 3 7

13 minus 7 is 6

6  13

 3 9 --

− 2 9 3 7

6

6 minus 3 is 3

6 13

 3 9 --

− 2 9 3 7

 3 6

9 minus 9 is 0

Answer:

Its 4

Step-by-step explanation:

Because it is

Answer:

4

Step-by-step explanation:

1) First, distribute the negative sign to the -7. Because of this, the -7 will become a positive 7.

Equation: -3+7

2) Next, whenever there are two different signs, we are supposed to subtract the bigger number (7) with the smaller number (3).

Equation: 7-3=4

3) Finally, assign the greatest number sign. in this case, 7 is the greater number, and the 7 is a positive number; therefore, it will be a positive 4.

Step-by-step explanation:

If one of them only ordered soda which costs $1.74 then you do 43.53 - 1.74 =41.79. Then do 41.79 divided by the other 7 people. 41.79 divided by 7 gets you the answer $5.97

Answer:

Step-by-step explanation:

Using the digits 8,4,7,2,9 and 0 to write a whole Number with 7 in the thousands place and 2 in the tens place :

The whole number is 6 digits long

100 thousand

10 thousand

Thousand = 7

Hundred

Tens = 2

Unit

Also the whole number is less than 500,000

Hence, number in the 100 thousand place is less Than 5,

Hence digit in the 100 thousand place = 4

Placing either 8 or 9 in the ten thousand place will mean That Josh's whole number is greater than 480,000

Step-by-step explanation:

Answer:ratio is 14:54 = 42:B. Beavers = 162

Step-by-step explanation:

The ratio demonstrates how often one number is multiplied by another.

The approximate number of beavers exists 162.

The ratio demonstrates how often one number is multiplied by another. When the second number in the ordered pair, b, is not equal to 0, the ratio is expressed as a/b. An equation in which two ratios are made equal is known as a percentage.

The relationship or comparison between two numbers in the same unit to determine how much larger one number is than the other is known as a ratio.

The 42 beavers were tagged and released by the New Jersey Division of Fish and Wildlife, which monitors the beaver population in the Raritan River. After a week, they had captured 54 beavers, 14 of which were marked. There are 54 Beavers in all, and 14 Beavers have tags.

Let the ratio be 14 : 54.

As 42 tagged beavers were released.

simplifying the above equation, we get

14 × 3 : 54 × 3

= 42 : 162

Therefore, the approximate number of beavers exists 162.

Answer:

58............will be the number

Answer:

[tex]d = \frac{w}{48}[/tex]

If  [tex]\frac{1}{48} \\[/tex] is constant, say k

Then,

[tex]d = kw[/tex]

∴ d ∝ w

Hence, weight is proportional to the density

Step-by-step explanation:

From the question,

Let w denote the weight of the rock in pounds

s denote the size of the rock in cubic inches and

d denote the density of the rock in pounds per cubic inch.

First, we will write the equation connecting w, s, and d.

We get

[tex]density (pounds/inch^{3} ) = \frac{weight(pounds)}{size (inch^{3}) }[/tex]

That is,

[tex]d = \frac{w}{s}[/tex]

Now, given a 48-cubic-inch rock with weight w pounds, to show the proportional relation between the weight and the density, we will write

[tex]d = \frac{w}{48}[/tex]

If  [tex]\frac{1}{48} \\[/tex] is constant, say k

Then,

[tex]d = kw[/tex]

∴ d ∝ w

Hence, density is proportional to the weight OR weight is proportional to the density
