<em>116 b.</em>
1280 × 24 = 30720
<u>30720 ÷ 60 = 512. 512 is the solution; the expression is divisible by 60.</u>
<em>116 c.</em>
3584 × 72 = 258048
<u>258048 ÷ 60 = 4096. 4096 is the solution; the expression is divisible by 63.</u>
<em>116 d.</em>
16250 × 24 = 390000
<u>390,000 ÷ 39 = 10,000. 10,000 is the solution; the expression is divisible by 39.</u>

The variance for this activity is mathematically given as
Var=0.026
<h3>What is the variance for this activity?</h3>A data set's variance may be seen as a measurement of the spread that exists between the individual integers. When evaluating the asset allocation of a portfolio, investors employ an expression known as the variance equation.
After careful consideration of the table given in the question, we have that
Pessimistic time tp=2
optimistic time to=1
most likely time tm=1.5
Generally, the equation for variance is mathematically given as
Therefore
Var=0.026
In conclusion, the variance for this activity
Var=0.026

Answer:
Step-by-step explanation:
In any 30-60-90 triangles, the sides are in ratio , where
is the side opposite to the 30 degree angle and
is the hypotenuse of the triangle.
In the given diagram, the hypotenuse is marked as 12 miles. Therefore, the side opposite to the 30 degree angle must be miles. The final leg,
, must then represent the
part of our ratio, hence
