I need help with this ASAP!!!!!
ICE Princess25 [194]

Answer:

x=3

Step-by-step explanation:

∠DBC+∠VBC is 180° since it is a straight line, ∠VBC=20x+5

The sum of all angles in a triangle is 180°, 9x-2 + 40° +∠DBC=180°

To find x, you can find ∠DBC first.  *Don't forget BRACKETS

∠DBC=180-(20x+5)

∠DBC=180-(9x-2 + 40°)

Now equal the equations to each other to find x.

180-(20x+5)=180-(40+9x-2)

180-20x-5=180-40-9x+2

175-20x=142-9x

175-142=20x-9x

33=11x

x=33/11

∴x=3

The line graph shows the number of goals scored
Neporo4naja [7]

Answer:

a) 1 game

b) 41 goals

c) median = 2

Step-by-step explanation:

a)

As we can see in the line graph, where we have the 0 for the number of goals scored, the graph indicates only 1 in the number of games, so we have only 1 game where no goals were scored.

b)

To find the total number of goals scored, we multiply the goals scored by the number of games for that score, and then sum them all:

total goals = 1*0 + 4*1 + 5*2 + 6*3 + 1*4 + 1*5 = 41 goals

c)

To find the median, we put all the goals in crescent order, and then find the value in the middle. As we have 18 games, the middle value will be an average of the 9th and 10th terms.

We have 1 number 0, 4 numbers 1 and 5 numbers 2 in the beginning, so for these 10 numbers, the 9th and the 10th are the score 2, so the median is 2.
