<span>=> 50 and 5000
Place value are very useful to compare given numbers. Place value gives ideas on how big the number is and helps you compare easily what is greater and lesser.

Let’s use the given number:
50 => 50 has 2 digit whole number, which means it has a place value of tens
=> 5 tens and 0 ones.

5000 => is a 4 digit whole number, which means it as a place value of 5000
=> 5 thousands 0 hundreds, 0 tens and 0 ones.

5000 is 100 times greater than 50.
=> 50 x 100 = 5000</span>

X varies directly with y. If x is 16 when y is 20, find x when y is 80.
Taya2010 [7]

Answer:

32

Step-by-step explanation:

16/20 reduces down to 2/5

set 2/5=x/80

cross multiply 160=5x

divide 32=x

check 2/5=32/80

32/80; 16/40; 8/20; 4/10; 2/5

yay 32 is the answer good luck :)

A random sample of 10 subjects have weights with a standard deviation of 9 8753 kg What is the variance of their weights? Be sur
hammer [34]

Answer: The variance of their weights = 9,752,155,009 kg.

Step-by-step explanation:

  • The variance is the square of the standard deviation . it measures the spread between data values in a data set.

So if standard deviation of 10 subjects = 98753 kg

Then, variance = (9 8753 )^2\ kg=9,752,155,009\ kg

Hence, the variance of their weights = 9,752,155,009 kg.

X&lt;= -2 on a number line
ruslelena [56]

Answer:

x\le \:-2\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:-2\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:-2]\end{bmatrix}

Please check the attached number line graph.

The number line clearly indicates that the graph is heading towards negative infinity from -2.

Step-by-step explanation:

Given the inequality expression

x ≤ -2

The inequality symbol ' ≤ ' means 'less than or equal to'.

Thus,

x ≤ -2 means x is less than or equal to -2.

In other words,

x\le \:-2\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:-2\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:-2]\end{bmatrix}

Please check the attached number line graph.

The number line clearly indicates that the graph is heading towards negative infinity from -2.
