Hey there!

An integer is a number without any decimals or fractions following it, such as -17, 5, 1000, etc. A rational number is any number that can be made into a fraction of two integers.

First, let's select all of our numbers that are NOT integers, which means that they will have things after the decimal point or a fraction.

0,4,-2,2/3,-1.8,16,3.2,-5/4

Now, we need to make sure that they are all rational numbers. Most numbers ARE rational. You don't need to make it into a fraction, but as long as it is a terminating or repeating decimal you are fine. Let's see what we have.

2/3=0.66666... Repeating decimal Rational

-1.8 Terminating Decimal Rational

3.2 Terminating Decimal Rational

-5/4= =1.25 Terminating Decimal Rational

The only numbers that are irrational are ones like pi or √2 that have digits that go on forever in no particular order.

Your numbers are 2/3, -1.8, 3.2, and -5/4.

I hope this helps!

A nursery has 10 tree seedlings to give out at 2 workshops. It wants to give out a minimum of 2 seedlings at each workshop. How

11111nata11111 [884]

We are given total 10 tree seedlings.

Number of workshops = 2.

Here order doesn't matters.

<em>When order doesn't matters we apply combination.</em>

We know formula of combination:

$C(n,r) = \frac{n!}{r!(n-r)!}$

For the given situation, we have

n=10 and r=2.

Plugging values in formula, we get

$\frac{10!}{2!(10-8)!} = \frac{10\times 9\times8!}{2!8!}$

$\frac{10 \times 9}{2} = \frac{90}{2} =45$

<h3>Therefore, 45 different ways can the nursery give out seedlings.</h3>

Which statement is true

loris [4]

Answer:

Step-by-step explanation

You must find the common denominator for all of them.

A is correct. 13 x 2 is 26 and 14 x 2 is 28. Therefore, 13/14 is greater than 25/28.

B is not correct. 4 x 5 is 20 and 9 x 5 is 45. 4/9 is actually less than 21/45.

C is not correct. 5 x 2 is 10 and 6 x 2 is 12. 5/6 is actually less than 11/12.

D is not correct. 4 x 5 is 20 and 5 x 5 is 25. 4/5 is actually less than 8/25.

A building may fail by excessive settlement of the foundation or by collapse of the superstructure. Over the life of the buildin

patriot [66]

Answer:

0.1536

Step-by-step explanation:

The computation of probability that the building failure will occur over its life is shown below:-

P(building failure) is

$P(ES \cup C)\\\\ = P(ES) + P(C) - P(ES\cap C)\\\\ = P(ES) + P(C) - P(ES) P (C | ES)\\\\ = 0.12 + 0.06 - 0.12 \times 0.22$

now we will solve the above equation

= 0.18 - 0.0264

After solving the above equation we will get

= 0.1536

Therefore for computing the probability that the building failure will occur over its life we simply applied the above formula.

Greg spent 6.4 hours working with his dad one Saturday. If his dad paid him$45.76, how much did Greg make per hour?

nordsb [41]

Answer:

$7.15

Step-by-step explanation:

The best way to solve this is by crossing out the data you don't need so you're left looking at the key pieces to put the equation together. If his dad paid him $45.76 for 6.4 hours, then all you need to do is divide 45.76 by 6.4. (Hint: Use a calculator, it makes it ten times faster than trying to write it out!)

45.76 ÷ 6.4 = 7.15

So Greg made $7.15 an hour working with his dad.
