4. In the given data set witch TWO measures are equivalent?
vredina [299]
The mode is the number that appears the most out of a given sequence.
30 appears the most.
Our mode is 30.
The median is the middle number of a list of numbers from least to greatest.
I will organize it for you.
20, 25, 30, 30, 30, 35, 45, 50, 100.
To determine the median the fast way, cross out the smallest number with the largest number until you can no longer do so.
20,25,30,30,30,35,45,50,100
25,30,30,30,35,45,50
30,30,30,35,45
30,30,35
30.
Our median is 30.
We do not need to figure out the mean, since we have found our answer;
Our mode and our median are equivalent.
I hope this helps!

If AB || CD, EF ⊥ CD and ∠GED = 135° as per the figure given below. Find the value of ∠AGE is
Bond [772]

Answer:

<h3>135°</h3>

Step-by-step explanation:

Find the diagram attached

From the given diagram, since AB is parallel to CD, this means both lines have similar properties.

For the triangle GEF, AFB, ∠GEF = ∠GED - ∠FED

Given ∠GED = 135 and ∠FED = 90

∠GEF = 135-90

∠GEF = 45°

Also, sum of angle in the triangle GEF is 180°, hence;

∠GEF + ∠EGF + ∠GFE = 180°

45°+∠EGF+90° = 180°

∠EGF+135° = 180°

∠EGF = 180-135

∠EGF = 45°

since the sum of angle on the straight line AGF = 180°, then;

∠AGE+∠EGF = 180°

∠AGE+45° = 180°

∠AGE = 180°-45°

∠AGE = 135°

<em>Hence the value of ∠AGE is 135°</em>
