Is one piece good? and how long is it?
Answer:
segment KL
Step-by-step explanation:
There is a theorem in geometry that deals with problem's question.
<em>Theorem:</em>
<em>In a triangle, a segment whose endpoints are midpoints of two sides is parallel to and half the length of the third side.</em>
In this triangle, you are shown that each side is made up of two congruent segments. That makes points J, L, and K midpoints of the three sides of the triangle.
Look at midpoints L and K. They are midpoints of sides YZ and XZ. Join them with segment KL. That segment is parallel to the third side of the triangle, side XY, and half of its length.
Answer: segment KL

Answer:176 psychology textbooks and 98 Biology textbooks were sold.
Step-by-step explanation:
Let x represent the number of psychology textbooks that were sold.
Let y represent the number of biology textbooks that were sold.
textbook store sold a combined total of 274 psychology and biology textbooks in a week. This means that
x + y = 274 - - - - - - - - - - -1
The number of psychology textbooks sold was 78 more than the number of biology textbooks sold. This means that
x = y + 78
Substituting x = y + 78 into equation 1, it becomes
y + 78 + y = 274
2y = 274 - 78
2y = 196
y = 98
x = y + 78 = 98 + 78
x = 176
Answer:
difference in the proportion = 0.0452
Step-by-step explanation:
x1 = 27, n1 = 193,
p1 = 27/193
p1 = 0.1399
x2 = 16, n2 = 169,
p2 = 16/169
p2 = 0.0947
a) The best estimate for the difference in the proportion of smokers, using male proportion minus female proportion is 0.0452. Male smokes more than females in given sample.
p1 - p2 = 0.1399 - 0.0947
p1 - p2 = 0.0452
