To find the mean you add all the numbers and divide it by the amount of numbers there is so add
6+9+15+22+30+36=118
there is 6 number so divide 118 by 6
118/6=<span>19.6666666667 rounded to the nearest tenth it would be 20
So your mean would be 20
let me know if you have any questions</span>
Answer:
Step-by-step explanation:
∠VTY is the tangent chord angle
- Tangent chord angle is the half of the intercepted arc
∠TSV is the inscribed angle.
- Inscribed angle is the half of the intercepted arc
<u>Since both of the mentioned angles refer to same arc, they are of same value.</u>
ΔTVS is isosceles as VS = ST, therefore the opposite angles are same.
<u>The measure of angle S</u>
<u>The required angle</u>
Answer:
BC ~ DE because of similar transformation
Step-by-step explanation:
ABC and DEF are not similar transformations the second one is wrong, the third one is wrong because. The last one ios right because by deduction it is.
Answer:
85-86%
Step-by-step explanation:
Make it an equation
You want to find the percent out of a hundred, so 42 is 100 since it is all of the questions and 36 is the unknown percent X
36/42 = X/100
36 X
42 100
Cross multiply
Do math and solve for X
36 x 100 = 42 x X
3600=42X
X=85.71
1. Take an arbitrary point that lies on the first line y=3x+10. Let x=0, then y=10 and point has coordinates (0,10).
2. Use formula 
to find the distance from point 
to the line Ax+By+C=0.
The second line has equation y=3x-20, that is 3x-y-20=0. By the previous formula the distance from the point (0,10) to the line 3x-y-20=0 is:
.
3. Since lines y=3x+10 and y=3x-20 are parallel, then the distance between these lines are the same as the distance from an arbitrary point from the first line to the second line.
Answer: 
.
