Answer:
B. 40
Step-by-step explanation:
What do you understand by sample size; a sample size is a little portion of a large number we which to investigate. Imagine we wanted to know the electricity consumption of people in a town of 200million people sometimes we could do that be investigating that of 50million especially when you know the conditions would be no different from others. In this sense the sample size is 50 million because that's the one we are investigating.
Similarly our concern of interest for investigation is 40, so that's the sample size.
Answer: 2 286/624
Step-by-step explanation:
96 * 16= 1536
125* 5= 625
2 286/ 625
Answer:
Compass bearings use the four directions on a compass in order to find the direction of one object from another. An example is N20°E. True bearings use the number of degrees measured clockwise from north an object is. An Example is 120°T.

Answer:
1. x=70
2. x=70
3. x=60
4. x=40
5. x=10
6. x=6
7. x=12
8. x=9
9. 88
10. 76
Step-by-step explanation:
1. Isosceles triangles have two sides equal to each other. If the unequal side is 40 degrees and there are 180 degrees in a triangle, 180-40=140/2=70 degrees for the other two sides.
2. Same explanation as 1.
3. Equilateral triangles all have the same degrees. If 60 is the degree for one angle, it is the degree for the other two as well.
4. Same explanation as 1.
5. All side length of an equilateral triangle are the same. If the side length of one side is 10, the other two sides are 10 too.
6. Same explanation as 5, but with 6 as the side length.
7. It is an isosceles triangle and two sides are equal. Since one side is 12 and the other side is the second of the equal sides, the side length would be 12
8. Same explanation as 7, but with 9 as the side length.
9. 180-46=134-46(other side length)=88 (remaining side length)
10. 2x+2+2x+2+3x+1=7x+5. 7x+5=180. 180-5=175. 175/7=25. 3(25)+1=76.
Hope this helps!!
