The new mean is 66.09
<u>Explanation:</u>
Mean weight of 20 students = 65kg
One student with 88kg entered the room.
New mean = ?
The above equation can further be written as:
New mean = 
= 66.09
Therefore, the new mean is 66.09
Answer:
∠ YVZ = 56°
Step-by-step explanation:
∠ WVZ = 90° ( given ), thus
∠ WVY + ∠ YVZ = 90, substitute values
2x + 3x + 5 = 90
5x + 5 = 90 ( subtract 5 from both sides )
5x = 85 ( divide both sides by 5 )
x = 17
Thus
∠ YVZ = 3x + 5 = 3(17) + 5 = 51 + 5 = 56°
180-40=140. 140/5 = 28
x= 28
angle B: 5(28) = 140
140 + 40 = 180
180=180
Answer:
A complete graph is a graph in which each pair of graph vertices is connected by an edge. The complete graph with graph vertices is denoted and has (the triangular numbers) undirected edges, where is a binomial coefficient. In older literature, complete graphs are sometimes called universal graphs.

Answer:
y-3=7/6(x-4)
Step-by-step explanation:
the equation for point-slope form is y-y1=m(x-x1)
first let's find the slope (m)
the formula for slope is (y2-y1)/(x2-x1)
the given points: (4,3) and (-2,-4)
label the points:
x1=4
y1=3
x2=-2
y2=-4
now substitute into the equation
m=(-4-3)/(-2-4)
m=-7/-6
m=7/6
the slope is 7/6
now substitute the numbers into the equation for point-slope form
y-3=7/6(x-4)
Hope this helps :)!
