Answer:
Don caught 3.6 kg and Dan caught 0.6 kg.
Step-by-step explanation:
Set up a system of equations:
Don's fish is the variable a and Dan's fish is the variable b.
a + b = 4.2 (1)
a=6b (2)
We can substitute a in the first equation using the second equation, so:
6b + b = 4.2
7b = 4.2
b = 0.6 kg
Dan caught 0.6 kg. Then, we can use equation 2 to find how much Don caught.
a = 6 x 0.6
a = 3.6
Don caught 3.6 kg.
Answer:

Step-by-step explanation:
Perimeter
Answer:
The mean of the measurements is 91.17.
Step-by-step explanation:
The mean is the sum of all measurements divided by the number of measurements.
For this problem, we have that:
The sum of all 100 measurements was 9117.0.
So, the sum of all measurements is 9117.
The number of measurements is 100.
So:
The mean of the measurements is 91.17.

Answer:
8 balls, 7 balls, 6 balls, 5 balls, 4 balls
Step-by-step explanation:
Since there are three blue balls & there maybe five additional balls with different colors, then the three balls can be taken as a single unit during arrangement/combination.
If the number of other balls with different colors aside blue is 5, the value of M will be 8.
If the number of other balls with different colors aside blue is 4, the value of M will be 7.
If the number of other balls with different colors aside blue is 3, the value of M will be 6.
If the number of other balls with different colors aside blue is 2, the value of M will be 5.
If the number of other balls with different colors aside blue is 1, the value of M will be 4.
