2x ! the number would be x and 2x is 2 times x!
If you roll two fair dice, a green one and a red one?
A= are the outcomes on the dice independent?
B= Find P(1 on green die and 2 on red die)
C= Find P(2 on green die and 1 on red die)
D= Find P(1 on green die and 2 on red die) or (2 on green die and 1 on red die)
A= yes
B= p(1)*(p2)=1/6*1/6=1/36
C= p(2)*(p1)=1/36
D= 1/36=1/18 I hope it helps !
Answer:
9 labours
Step-by-step explanation:
In order to solve this, we must know which kind of proportionality is this. There are two types of proportions, direct and indirect/inverse proportions. In direct proportion, if one quantity increases, the other quantity also increases.
In indirect proportion, if one quantity increases, the other decreases and vice versa.
As per this question, we know if the number of labour increases, the number of days to complete a work decreases, thus proving that this is an indirect/inverse proportion.
6 labours => 12 days
x labours => 8 days
Since its an inverse proprotion, multiply 6 with 12, and x with 8.
8x = 6 × 12
x =
∴ x = <u>9 labours</u>
Answer:
The answer is 20 hamburgers and 25 hot dogs.
20(.5)+25(.25)<16.5
10+6.25<16.5
16.25<16.5
The budget is $16.50 and $16.25 is $.50 less therefore making it a possible option for Enrique.
