Simplify the expression below. Which of the following is correct? \(\frac{[3 (2 + 6 \ast 4)]}{(26 \div 2)}\)  

A. 6

B. 8

C. 12

D. 9

Answer Explanation:

We follow the order of operations to solve the given expression.

First, we start with the numerator and solve it as follows

[3(2+6*4)]

We start with multiplication in inner brackets, 6*4=24. The expression becomes

[3(2+24)]

Then, we conduct the addition of 2+24=26. Then, the expression becomes

[3(26)]=3*26=78

Now, we solve for denominator, which is 26/2=13.

Thus, the expression is reduced into

\(\frac{[3(2+6\ast4)]}{(26\div2)}=\frac{78}{13}=6\)

The expression reduces into 6.

Therefore, the Correct Answer is A.

    A. 80

    B. 78

    C. 96

    D. 81

    Answer Explanation

    the mean of a data set is the total scores divided by the number of tests.

    Total test scores =80+68+74+87+96=405
