Answer:

Option C

Step-by-step explanation:

Add all grades together:

79 + 80 + 92 + 92 + 81 + 100 + 88 + 98 + 71 + 100 + 91 + 90 = 1062

Divide the total by the number of grades in the set:

1062/12 = 88.5

The average of the grades is 88.5%, therefore Option C should be the correct answer.

Y + 4/9 = 6/9
Subtract 4/9 on both sides.

Y = 2/9 Hope this helps!

hoa [83]

Answer:

The correct answer is option B.  

m<3 = m<6

Step-by-step explanation:

From the figure we an see that, a and b are parallel lines and line t is the traversal on the lines.

<u>To find the correct option</u>

From the given figure we get

Corresponding angles are,

<1 & <5,  <2&<6, <2&<7 and <4 &<8

Alternate interior angles are,

<3 & <6  and <4 &<5

Alternate interior angles are equal.

m<3 = m<6

Therefore the correct answer is optionB
