A^2-8a-48=0
factor
(a+4)(a-12)=0
set each equal to 0
a+4=0 a-12=0
a=-4,12
Answer:
Upper deck = $38
Goal View = $63
Sidelines = $88
Step-by-step explanation:
Represent
- Sidelines with S
- Goal-view with G
- Upper-deck with U
We have that:
Required
Solve for S, G and U
Substitute 25 + G for S in the second equation
Make G the subject
Substitute 25 + U for G in the third equation
Collect Like Terms
Substitute 38 for U in
Substitute 63 for G in
Answer:
Step-by-step explanation:
Given that the Pick 4 games in many state lotteries announce a four‑digit winning number each day. Each of the 10,000 possible numbers 0000 to 9999 has the same chance of winning. You win if your choice matches the winning digits. Suppose your chosen number is 3079 .
a) The probability that the winning number matches your number exactly
= 1 out of 10000 = 0.0001
b) the probability that the winning number has the same digits as your number in any order
This includes 0379, 0397, 0739, 0793, 0937, 0397 i.e. starting from 0 there are 6 = 3! ways
Or 3079 can be arranged in 4! ways = 24
Favorable outcomes = 24
Prob of winning = 24/10000 = 0.00024
=0.0002
