A certain model car has a keypad with 5 numbers on the door. To open the door, 5 numbers must be entered in the correct
order and no number can be used more than once. What is the probability that someone could guess the correct code?
OA. Ito
OB.
OC.
OD.
Answer: A. [tex]\dfrac{1}{120}[/tex]
Step-by-step explanation:
Total digits on keypad = 5
According to permutation,
If repetition of digits is not allowed then the number of 5-digits passwords can be formed = 5!
= 5 x 4 x 3 x 2 x 1 [n!=n x (n-1) x (n-2)x ... x 1]
=120
The probability that someone guesses the correct code = [tex]\dfrac{\text{Number of correct codes}}{\text{Total possible codes}}[/tex]
[tex]=\dfrac{1}{120}[/tex]
Hence, the correct option is A.

A ceramic vase that cost an antique store $7 was marked $63. What is the percentage markup on the price of the ceramic vase?
A-56%
B-900%
C-800%
D-44%

What is the solution to the equation x÷8−6=3?
A. x=1
B. x=24
C. x=48
D. x=72
30 POINTS TO THE RIGHT ANSWER AND BEST EXPLANTION.
Answer: D. x=72
Step-by-step explanation:
With the equation x/8-6=3 we can start solving by first moving the "-6"
x/8-6(+6)=3(+6)
x/8=9 <-- Rewrite equation after adding "6" to both sides
x/8(*8)=9(*8) <--- Multiply both sides by 8
x=72 <-- After multiplying, solution is found

cm per minc) Point (8, 28) indicates:
Water level of 28 cm after 8 mind) x = 20, y =?
y = 3.5(20) = 70 cmIf JK = 8x + 24 and NO = 20, what is the value of x?
Answer:
x=2
Step-by-step explanation:
So..
NO=1/2 of JK because the two segments are parallel
Therefore because you have NO plug that into..
NO=1/2JK
YOU GET
1/2JK=20 multiply 2 so you can isolate JK
JK=40
Then plug that back into your JK=8x+24
40=8x+24 next subtract 24 on both sides
8x=16
x=2
Hope this helps!
what is the value of x?
Answer:
x=10
Step-by-step explanation:
Well, lets see. 5x+9x+40 is 180 degrees. So 14x+40=180. 14x=140. So x=10
