Answer:

Yes, rational numbers are equal to integers.

Step-by-step explanation:

<u>Step 1: </u>

As we know every integer is rational number.

Integer can be written in the form n/1.

<u>Step 2: </u>

Consider the below example to understand about rational number.

Example:

6 = 6/1 and thus 6 are not irrational number.

Also numbers like ¼, 481599/45565 and -5/7 are also rational numbers, as they are fractions whose nominator and denominator are integers.

<u>Step 3: </u>

Integers are whole numbers, negative whole numbers and zero.

Example:

486699, 32, 5, 0, -35,-3022

Whereas numbers like ½, 5.5558, 8.5, Pi and -25.55 are not integers.

So we can conclude rational numbers are equal to Intergers.

Find the mean, range, and interquartile range of the heights of plants given
Artist 52 [7]

Answer:

Mean = 30.9

Range = 80

Interquartile Range = 36

Step-by-step explanation:

The mean of a set of numbers is the sum divided by the number of terms. In other words that means 2, 22, 4, 36, 82, 44, 65, 30, 8, 16 go over a fraction like this. There are 10 numbers here so this is our denominator.

\frac{2+ 22 + 4 + 36 + 82 + 44 + 65 + 30 + 8 + 16}{10}

\frac{309}{10} > 30.9

For the range, all we do is subtract the minimum value from the maximum which is 82 - 2. That gives us 80.

For the IQ Range....

Arrange the terms in ascending order.

2, 4, 8, 16, 22, 30, 36, 44, 65, 82

Then we need to find the median which is the average of the two middle terms.

\frac{22+30}{2} > \frac{2*11 + 30}{2} >\frac{2*11+2*15}{2} > \frac{2 * (11 + 15)}{2} > 11 + 15 > 26

So for the lower half of data 2, 4, 8, 16, 22 we have the median of 8

And for the upper half 30, 36, 44, 65, 82 we have the median of 44.

To find the IQ Range it is the difference between the first quartile (8) and the third (44)

So 44 - 8 = 36

a contractor bought a rectangular piece of land that has a perimeter of 200 feet. the ration of the land's length to width is 9:
PIT_PIT [208]

Answer:

length/width = 1/1 = 1

Step-by-step explanation:

(3x)(2x) = 12150

6x^2 = 12150

x^2 = 2025

x = 45

Length is 135 ft, width is 90 ft, perimeter is 450 ft

Geometric mean: 135 : x :: x : 90

x^2 = 12150

x = 45√6

The second rectangular piece of land is a square !

length/width = 1/1 = 1

What is the product of 2x+ 3 and 4x2 - 5x+ 6?
elena-s [515]

Answer:

8x³ - 25x² - 3x + 18

Step-by-step explanation:

(2x + 3)(4x²- 5x + 6)

multiply 2x by each of the three terms in the second expression to get:

8x³ - 10x² + 12x

now multiply 3 by each of the three terms in the second expression to get:

12x² - 15x + 18

Combine 'like terms': -10x² + (-15x²) = -25x²

Combine 'like terms':  12x + (-15x) = -3x

Put all terms in decreasing exponent order:

8x³ - 25x² - 3x + 18
