So I'm hoping you mean 6, or else the probability is 0. So the possible ways of getting a sum of 6 is 1&5, 2&4, 3&3, 4&2, 5&1. There are 36 different ways of rolling the dice, so divide the 5 possible ways by 36. Then, we need to add the possibility of getting at least one 6 in the roll. It doesn't matter what the other die is, so for each die, the probability is 1/6, and for both, the probability is 2/6. Add this to the probability of getting a sum of 6, and you get your answer.
<u>Answer:</u>
The temperature change per hour was -3 degrees per hour.
<u>Step-by-step explanation:</u>
We know that the temperature fell from 
degrees to 
degrees in a time period of 
hours.
So to find the rate of change of the temperature, we will divide the change in temperature by the number of hours.
For that, we will change the mixed number into improper fractions and then solve:
Temperature change per hour = 
Therefore, the temperature change per hour was -3 degrees per hour.
Answer:
y = kx
Step-by-step explanation:
If y varies directly as x
That means y = kx
Where k is the constant of proportionality
If y = 18 and
x = 5
K= ?
Using y = kx
18 = k x 5
Divide both sides by 5
18/5 = k x 5 /5
3 3/5 = k
K = 3 3/5
Now , when x = 11
The expression to find y is
y = kx
Since k = 3 3/5 and
x = 11
y = 3 3/5 x 11
y = 18/5 x 11
Multiply through
y = 198/5
y = 39 3/5
3x is the miles from downstream
4 (x - 1) is the return trip
Solution:
3x = 4 (x - 1)
3x =4x - 4
-x = -4
x = 4
The outward journey 3x = 12 miles
Return journey is same length
Therefore the distance travel is 24 miles
