Answer:x<= -27

Step-by-step explanation:

Solve the inequality as if you're solving a regular equation. Remember that if you divide or multiply by a negative number you must flip the direction of the inequality.

x<= 3 (-9)

x<= -27

The data below gives the number of books that 15 students checked out of the school library in one month. Make a frequency table
Alex
Answer: See the explanation below.

A frequency table is a way to organize data. We create bins (intervals) to collect the data. Then, we give the frequency (number) of data values in each interval.

Here is an example of how you could sort this data.

Interval:     Frequency:
0 - 1                  7
2 - 3                  7
4 - 5                  1

#2 <br> #3 <br> Need help for my discrete math class
miss Akunina [59]

For (2), start with the base case. When n = 2, we have

(n + 1)! = (2 + 1)! = 3! = 6

2ⁿ = 2² = 4

6 > 4, so the case of n = 2 is true.

Now assume the inequality holds for n = k, so that

(k + 1)! > 2ᵏ

Under this hypothesis, we want to show the inequality holds for n = k + 1. By definition of factorial, we have

((k + 1) + 1)! = (k + 2)! = (k + 2) (k + 1)!

Then by our hypothesis,

(k + 2) (k + 1)! > (k + 2) 2ᵏ = k•2ᵏ + 2ᵏ⁺¹

and k•2ᵏ ≥ 2•2² = 8, so

k•2ᵏ + 2ᵏ⁺¹ ≥ 8 + 2ᵏ⁺¹ > 2ᵏ⁺¹

which proves the claim.

Unfortunately, I can't help you with (3). Sorry!

Write 1,000 as a power of 10.
8_murik_8 [283]

Answer:

10^{3}

Step-by-step explanation:

Any positive integer power of 10 is the number of times 10 multiply by itself. In case power remain zero then the result will be just one.

10^{0} = 1\\ \\10^{1} = 10\\ \\10^{2} = 10\times 10 = 100\\ \\10^{3} = 10 \times 10\times 10 = 1000

As given, we need to write 1000 as a power of 10

∴ 10^{3} = 10\times 10\times 10 = 1000
