What is the volume of a box with a width 2 1/2 inches, length 1 3/4 inches, and height 3 1/4 inches?
enot [183]

Answer:

The volume of the box is 41.21 inches cube.

Step-by-step explanation:

Given,

Width of the box 2\frac{1}{2} inches

                           =\frac{5}{2} inches  

Length of the box 1\frac{3}{4}inches

                           =\frac{7}{4} inches

Height of the box 3\frac{1}{4} inches

                            = \frac{13}{4} inches

The box is in cuboid form.

The volume of cuboid is given by (length × breadth × height ).

So,

volume of the box is  ( \frac{5}{2}  × \frac{7}{4} × \frac{13}{4} )

                                    = ( \frac{455}{32} )

                                    = 14.21 inches cube

 The volume of the box is 41.21 inches cube.

A train travels 250 miles at a constant speed (x), in miles per hour.Enter an equation that can be used to find the speed of the
Nastasia [14]
The first thing we must do for this case is to take into account the following variable:
 x = speed in miles per hour
 Then, by definition we have to:
 d = v * t
 Where,
 d: distance
 v: speed
 t: time
 Substituting values:
 250 = x * 5
 Answer:
 
An equation that can be used to find the speed of the train is:
 
250 = x * 5

Jerry took a sample of 4 employees in his office and observed how many hours they each worked one day.
Illusion [34]

The error in Jerry's calculation is 4.84

The number of employees, N = 4

The mean is calculated as:

\mu = \frac{10+2+4+8}{4} \\\mu = \frac{24}{4} \\\mu = 6

The formula for the standard deviation is:

SD =\sqrt{\frac{\sum{(x-\mu)^2}}{N} }

This can be further calculated as:

SD = \sqrt{\frac{(10-6)^2+(2-6)^2+(4-6)^2+(8-6)^2}{4} }\\\\SD = \sqrt{\frac{4^2+(-4)^2+(-2)^2+(2)^2}{4} } \\\\SD = \sqrt{\frac{16+16+4+4}{4} } \\\\SD = \sqrt{\frac{40}{4} } \\\\SD = \sqrt{10} \\\\SD = 3.16

Jerry thinks the Standard Deviation = 8

The true Standard Deviation = 3.16

Error = |True value - Measured value|

Error = |3.16 - 8|

Error = 4.84
