Answer:
C
Step-by-step explanation:
Let's break down the definitions.
Supplementary = degrees add up to 180
Vertical = share a common vertex
Complementary = degrees add up to 90
Adjacent = share a common side and vertex
Since the degrees add up to 90 and don't share a common side/vertex, the angles are complementary.
The range of Ervin's scores is 55.
Range is the difference between the largest number and the smallest number.
To find the range of a set of values, first sort the values numerically (smallest to largest). With this set, it would look like this: 138, 142, 155, 165, 172, 193. Lastly, subtract 138 from 193 to find the range. By doing so, you will get 55 as an answer.

Answer:
x= -7 x = -4
Step-by-step explanation:
x^2 + 11x + 28 = 0
What two numbers multiply to 28 and add to 11
7*4 = 28
7+4 =11
(x+7) (x+4) =0
Using the zero product property
x+7 =0 x+4 =0
x= -7 x = -4
Her score in computer to get a proportionally weighted average of 46% will be 134.
The total score for both subjects = 200 + 300 = 500
Since the proportionally weighted average is 46%, then her score will be:
= 46% × 500
= 0.46 × 500
= 230
Since she had 32% for her statistics test, which was out of a total of 300. Her score will be:
= 32% × 300
= 0.32 × 300
= 96
Therefore, her score in computer will be:
= 230 - 96
= 134
