A piece of cable 8.5 cm long weighs 52 grams. How much does a cable that is 10 cm long weigh

Arturiano [62]

8.5 cm cable weighs = 52 grams

1 cm of cable weighs = $\frac{52}{8.5}grams$

  = $52/ \frac{85}{10}$ grams

= $\frac{520}{85}$ grams
= $6.11764$ grams
Rounding it up = 6. 10000 grams

Then,

Constant Added score = 10

The mean of scaled test score will be:

Mean score + constant added score

68 + 10 = 78

The standard deviation remains unchanged ; Hence, standard deviation = 14
