(a² - 4a + 6) + (3a² + 13 - 1)
= a² + 3a² - 4a + 13a + 6 - 1
= 4a² + 9a + 5
Hope this helps! :)
Answer: Hello mate!
In a fair die all the number have the same probability; 1/6
The probability of getting a 4 is the sides with the number 4 divided by the total amount of numbers in the dice, this is 1 divided by, the probability is 1/6
The probability o getting a number divisible by 3 is the number of numbers that are divisible by 3 divided by the total amount of numbers in the dice:
The numbers divisible by 3 are 3 and 6, and in the dice, there are 6 numbers in total, so the probability is 2/6 = 1/3
time profit number
truck 10 min 1.00dollar t
car 12min 1.50 dollar c
boat 8min 0.60 dollar b
let the worker produce t trucks, c cars, and b boats.
10t+12c+8b=400
t+1.5c+0.6b is more than or equal to 35
t is more than or equal to 0
c is more than or equal to zero
b is more than or equal to zero
(this question is kinda wierd. i do not know if i am correct, because mine is not exactly a system of inequalities, but if you really need an answer, you can try this one.)
Answer
