Answer:

1) 15

2) 4.5

Step-by-step explanation:

1 ) 10, 12, 16, 17,20

Average = \frac{\text{Sum of all observations}}{\text{Total no. of observations}}

Average = \frac{10+12+16+17+20}{5}

Average = 15

2) 0, 3,6,9

Average = \frac{\text{Sum of all observations}}{\text{Total no. of observations}}

Average = \frac{0+3+6+9}{4}

Average = 4.5

Can someone help me with this question please
Zarrin [17]

Answer:

Step-by-step explanation:

y+ 20= x+ 15( Vertically opposite angles)

y+ 20- 15= x

x= y+ 5 __(1)

3x+ 5=4y- 15

Substituting (1)

3(y+5)+ 5= 4y-15

3y+15+5=4y- 15

y=15+20

y= 35

x= 40
