Since there is no repetition allowed, there are 10 possibilities for the 1st digit, 9 for the 2nd, 8 for the 3rd, and 7 for the 4th. This gives a total of (10)(9)(8)(7) = 5040 four-digit codes.
For all odd digits to be used, there are 5 possibilities for the 1st digit (1,3,5,7,9), 4 for the 2nd, 3 for the 3rd, 2 for the 4th. This gives a total of (5)(4)(3)(2) = 120 codes that only use odd digits.
Therefore there are 5040 - 120 = 4920 codes that do not consist of all odd digits. The probability is 4920/5040 = 41/42.
Answer:
12 is not a solution.
Step-by-step explanation:
1. Solve for w
8w = 99
w = 99 / 8
w = 12.375
12 is not a solution.
<u>B) </u>
<u>C) </u> volume = 
.
<u>Step-by-step explanation:</u>
Here we have , The base of an open rectangular box is of length (2x+5) cm and width x cm. The area of this base is 58cm^2. The height of the open box is (x-2) cm. We need to find the following :
a) show that 2x^2+5x-58=0
We know that area of rectangle = 
⇒ 
Putting values according to question we get :
⇒ 
⇒ 
⇒ 
b) solve the equation in the question above, giving your answer to 2 decimal places
Solving this equation :
⇒
By quadratic formula
⇒ 
⇒ 
⇒ 
⇒ 
{ Since side can't be negative ! }
⇒
c) calculate the volume of the box, stating units of you answer
Since x = 4.28 , other sides are
We know that volume is given by :
⇒ 
⇒ 
⇒
Therefore , volume = .
Answer: The movie theater sold 434 a day
Step-by-step explanation:
How I got 434 a day
So
If you multiply 434 x 6 = 2,604
so they sold 2,604 in 6 days.
Let me know if I did something wrong.
