How many minutes greater is the software company's median than the bank's median?
morpeh [17]
10.

The median is calculated by taking all values in a data set, placing them in order from least to greatest, and finding the value that is in the middle of the data set. In this case, the middle number (median) for Bank is 15. The middle number (median) for Software Company is 25. The difference between 25 and 15 is 10. So Software Company is 10 more minutes greater than Bank,

If the measure of angle 5 is (11 x minus 14) degrees and x = 6, which expression could represent the measure of angle 2? 3 lines
g100num [7]

Answer:

The measure of angle 2 is 52°.

Step-by-step explanation:

Consider the below figure attached with this question.

It is given that

m\angle 5=(11x-14)^{\circ}

and x=6.

From the below figure it is clear that Lines 1,2 and 3 intersect each other at a point and form 6 angles.

It is clear that angle 2 and angle 5 are vertical opposite angles because these angles created by intersection of line 2 and line 3.

If two lines intersect each other then vertical opposite angles are congruent.

m\angle 2=m\angle 5                   (vertical opposite angles)

m\angle 2=(11x-14)^{\circ}

Substitute x=6.

m\angle 2=(11(6)-14)^{\circ}

m\angle 2=(66-14)^{\circ}

m\angle 2=52^{\circ}

Therefore, the measure of angle 2 is 52°.
