Step-by-step explanation:
The marginal totals are the sum of each row and column.
For example, the total number of sophomores is 120 + 302 = 422.
See picture of table with marginal totals filled in.
Answer:
x = 1/3
Step-by-step explanation:
Move all terms containing x to the left side of the equation.
8+6x=10
Move all terms not containing x to the right side of the equation
6x=2
Divide each term by 6 and simplify.
Exact Form:
x=1/3
Decimal Form:
x=0.3333333333
Hope this helps!

Answer:
Explained
Step-by-step explanation:
This algorithm does not always give the optimal solution. There is an alternate method as well.
Consider we have to make change for 30 cents, using the least number of coins of denominations 1,10 and 25 cents.According to the given strategy, we first take a 25 cents coin and subtract it from 30 cents. Now, we have to make 5 cents which we can make only from 5 one-cent coins. So, the total number of coins required is 6 according to the given greedy strategy.
But we can simply use 3 ten-cent coins to make change of 30 cents. So, this example proves that the given strategy is not an optimal one.
I’m assuming “triple 4” is just 3 times 4.
Using the information from the problem, we can form an equation that reads,
3*4 + 7*7
Solve:
12 + 49 = 61
The answer is 61
