Let x be the number of students that like both algebra and geometry. Then:
1. 45-x is the number of students that like only algebra;
2. 53-x is the number of students that like only geometry.
You know that 6 students do not like any subject at all and there are 75 students in total. If you add the number of students that like both subjects, the number of students that like only one subject and the number of students that do not like any subject, you get 75. Therefore,
x+45-x+53-x+6=75.
Solve this equation:
104-x=75,
x=104-75,
x=29.
You get that:
- 29 students like both subjects;
- 45-29=16 students like only algebra;
- 53-29=24 students like only geometry;
- 24+6=30 students do not like algebra;
- 16+6=22 students do not like geometry.
The correct choice is D.
A)The outlier if the data is 28 because it is 30+ numbers away from the next number. B) The mean for this data is 67.45. C) it would be 71.4 without the outlier. P.S to find the mean you add all the numbers together and then divide it by however many numbers there are. Hope this helps
Error in the weight is 0.3g (Difference between the actual 36.8g and the experimented 36.5g)
So %Error = Error/Correct value *100%
= 0.3/36.8 *100 =<span>0.815% = 0.82% (2 significant figure)

The angle swept out is equal to 1/12 of a full rotation is π/6 radians.
r^2 * theta = π/6 * 11.25^2 = 66.268"
Answer:
96 cm^2
Step-by-step explanation:
The triangle can be split into 2 6-8-10 triangles, each with area 24. The bottom parallelogram area is base times height, or 8 * 6, so 48. 24 + 24 + 48 is 96.
