Since the mean height in a group of students is 1.65 meters, that is the average height in that group.
Best of Luck!
All are correct except C
You need to check: A, B and D
Hope it helps.
The measure of the value of x is 49.5 degrees, the correct option is B.
Given
The measure of arc QS is (4x – 18)°.
<h3>The measure of arc</h3>
Arc QS is a semicircle and hence subtended angle by semicircle at the center is 180 degrees.
The measure of the arc QS is (4x – 18)° is equal to 180 degrees.
Then,
The value of x is;
Hence, the measure of the value of x is 49.5 degrees.

Answer: 44°
Step-by-step explanation:
The sum of the exterior angles of a polygon is 360°
If your polygon has six sides, the final angle will be:
= 360 - (63 + 64 + 82 + 49 + 58)
= 360 - 316
= 44°
199•25%=49.75
49.75+199=248.75
248.75•7.5%=18.65625
18.65625+248.75=267.40625
therefore the answer is $248.41
