Answer:

15.8

Step-by-step explanation:

since you're trying to figure out the perimeter of the rectangle you would use the formula 2L + 2W.

3.7 times 2 is 7.4

and 4.2 times 2 is 8.4  

so, add 7.4 and 8.4

<u><em>= 15.8</em></u>

Answer:

15.8m

Step-by-step explanation:

Your perimeter is given by the sum of four sides of the rectangle:

Perimeter = 3.7m*2 + 4.2m*2 = 7.4m + 8.4m = 15.8m

Answer:

The correct option is;

The first twenty-five customers

Step-by-step explanation:

For the given data, by calculation, we have;

The population average = 11.45

The average of the first five customers = 13.2

The average of the first ten customers = 11.6

The average of the first twenty customers = 12.5

The average of the first twenty-five customers = 11.72

Therefore both the first ten customers and the first twenty-five customers have good representation of the population mean with the mean of the first ten customers having a value of 11.6 is more closer to the population mean than the mean of the first twenty-five customers

However, by the central limit theorem, as the size of the sample continues to be increasingly larger, it becomes more and more representative of the population mean, this is more so because when the data is sorted, the population mean will be better represented by the mean of a large sample size

Hence the set of sample data needed to best represent the population mean is the first twenty-five customers.

Solid A is dilated using a scale factor of 2⁄5, resulting in Solid B. Solid B is also dilated using a scale factor of 2⁄5, resul
Lyrx [107]

Answer:

28.8 and 180

Step-by-step explanation:

you just times B by 2/5 to get C and divide it by 2/5 to get A

C = (72)(2/5) = 28.8 km³

A = (72)/(2/5) = 180 km³

We know the answers make sense because A shrinks to get B and B shrinks to get C, and our answers match that.

26 inches is how many yards
AlekseyPX

1 yard = 36 inches

The fraction  (1 yard / 36 inches) has a numerator and denominator
that are equal.  So the fraction is equal to ' 1 ', and we can multiply
(26 inches) by it without changing any value.  That'll change the units
of the '26 inches' to 'yards', which is exactly what we need.

(26 inches) x (1 yard/36 inches) = (26/36) yard

                                                 That's  13/18 yard, or  0.7222... yard.
