Answer:

72.5

Step-by-step explanation:

When rounding to the tenths place you have to look at the hundreths place, if its greater than or is 5 the the tenths place goes up one if not it stays the same. so here 6 is greater than 5 so the .4 rounds to .5

Are the equations lxl – 3 = 7 and [x] = 10 equivalent?
zvonat [6]

They're not equivalent.

|x| (vertical bars) represents the absolute value of x. How it works is that it turns negative numbers positive but leaves 0 and positive numbers alone (hence it gets a number's distance from 0 on the number line).

[x] (square brackets) usually represents the floor function, which returns the largest integer that is less than or equal to x. (The floor of x can also be written as \lfloor x \rfloor --- it depends on what your textbook/source says).

To solve |x| - 3 = 7, you first transform it into the equivalent equation |x| = 10. Then by definition of absolute value, there are only two solutions for the first equation: x = 10 or x = -10.

[x] = 10 has infinitely many solutions. For example, the floor of 10 is 10, so [10] = 10, thus a solution for the second equation is x = 10

The floor of 10.1 is 10, so [10.1] = 10, thus another solution for the second equation is x = 10.1.

The two equations do not have the same solution set (as x = 10.1 does not solve |x| - 3 = 7 but solves [x] = 10), so they're not equivalent.

A small box measures 3 1/3 in. by 2 3/4 in. by 1 5/6 in. high. What is the volume of the box? Show your work
Mashutka [201]

Answer:

The volume is 16 29/36 or 16.81

Step-by-step explanation:

Volume of a box v = Length l × width w × height h

l = 3 1/3 = 10/3, b = 2 3/4 = 11/4, h = 1 5/6 = 11/6

v = 10/3 × 11/4 × 11/6

v = (10*11*11)/(3*4*6)

= 1210/72

V = 605/36

≈ 16 29/36 or 16.81

In order to measure the dispersion of a random variable, look at its a. standard deviation. b. mean. c. expected value. d. avera
Sphinxa [80]

Answer:

a. standard deviation

Step-by-step explanation:

Dispersion is a measure of variability in a given data i.e the level or extent of spread of a data. This can easily be measured for a random variable by considering its standard deviation.

The standard deviation would show the extent to which each value is different from the mean. Thus showing the extent of the dispersion of variables.

Therefore, to measure the dispersion of a random variable, look at its standard deviation.
