(15×1+27×2+8×3+5×4)÷15+27+8+5=2.054.....≈2

ReplyDeleteThe mean is 2

The mean is 2 parking spaces, answer is rounded off

ReplyDeleteThe answer is about 2

ReplyDelete(15x1+27x2+8x3+5x4)/15+27+8+5=2.054545455.....

ReplyDeleteThe answer is rounded off to 2.

((15×1)+(27×2)+(8×3)+(4×5)) ÷ (15+27+8+4) =

ReplyDelete(15+54+24+20) ÷ 54

113 ÷ 54 ≈ 2

The mean is 2

15x1+27x2+8x3+5x3/15+27+8+4 = 2

ReplyDelete= is equal to the estimation sign(wavy equal sign)

The mean is 2

(15x1)+(2x27)+(3x8)+(4x5)=113

ReplyDelete113 /(15+27+8+5)=2.0545454

Round off to 2

((1x15)+(2x27)+(3x8)+(4x5))÷(15+27+8+5) = 2.054 ≈ 2

ReplyDeleteWhen rounded off, the answer is 2.

ReplyDelete15x1+27x2+8x3+5x3/15+27+8+4 = 2.054...

ReplyDeleterounded off is 2

mean=total/frequency

ReplyDeletetotal=(1*15)+(2*27)+(3*8)+(4*5)

= 15+54+24+20

= 113

frequency=15+27+8+5

=55

mean=113/55

rounded off=2

the mean is 2.

（15x1)+(27x2)+(8x3)+(4x5)/15+27+8+5 = 113/55 rounded of=2

ReplyDeleteMean= (1x15)+(2x27)+(3x8)+(4x5) / 15+27+8+5 = 2.0545454.... rounded off = 2

ReplyDelete(15x1+27x2+8x3+4x5)/ (15+7+8+5)=2.054545...rounded off to nearest whole number= 2

ReplyDelete(15×1+27×2+8×3+5×4)÷15+27+8+5=2.05454545454...≈2

ReplyDeletethe mean is about 2.

113/55 is about 2.

ReplyDeleteThe mean is approximately 2.
