Which graph shows the correct representation of {x | x ≤ 5}?
Andrew [12]

Answer:

third choice

Step-by-step explanation:

That would be the third one. It has to be a closed circle because it includes the sign, ≤ meaning that it also has the number 5 included. The numbers that go to the left of 5 are smaller, too.

for the given license plate configuration, determine how many different plates are possinle if letters and digits (a) can ba rep
Inessa05 [86]

Answer:

a) 1,757,600 different plates possible.

b) 1,404,000 different plates possible.

Step-by-step explanation:

The permutations formula is important to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

P_{(n,x)} = \frac{n!}{(n-x)!}

(a) can be repeated:

There are 3 letters, each one with 26 possible outcomes.

2 digits, each with 10 possible outcomes

So

T = 26*26*26*10*10 = 1757600

1,757,600 different plates possible.

(b) cannot be repeated:

Here the permutations formula is used.

Three letters, from a set of 26.

Two digits, from a set of 10. So

T = P_{(26,3)}*P_{(10,2)} = \frac{26!}{(26-3)!}*\frac{10!}{(10-2)!} = 1404000

1,404,000 different plates possible.

8 to 11 do it with equations thx
Alenkasestr [34]

Answer:

Step-by-step explanation:

8. 4\geq x+\frac{3}{4}

4(4\geq x+\frac{3}{4} )

16\geq 4x + 3

-3         -3

13\geq 4x

\frac{13}{4}\geq \frac{4x}{4}

\frac{13}{4} \geq x = x\leq \frac{13}{4}

x\leq \frac{13}{4}=3.25

9. x-3\leq -8

       +3     +3

x\leq -5}

10. 4\leq x-7

  +7         +7

11\leq x=x\geq 11

11. 6.9 < x - 2.3

 + 2.3      + 2.3

 9.2 < x = x > 9.2

Hope this helps!
