Question

Garrick and Zan are measuring the heights of seedling plants for science class.

Use the drop-down menus to complete the statements about the measured heights and the actual heights of the plants.
CLEAR CHECK
Because Garrick's plant is... than Zan's plant, each millimeter of error results in a ....percent error.

Garrick's measurement was ... millimeters off and Zan's was... millimeters off, so Garrick's measurement was ... % off and Zan's was

Answer 1

Garrick's measurement was 2 mm off. (10 - 8 = 2)
Zan's measurement was 12 mm off. (100 - 88 = 12)

Garrick's percent error was 20% (2 / 10 x 100)
Zan's percent error was 12% (12 / 100 x 100)

Answer 2

Answer: Garrick's plant is shorter than Zan's plant.

Each millimeter of error results in a 11.11% percent error.

Garrick's measurement was 2 millimeters off and Zan's was 12 millimeters off.

Garrick's measurement was 20% off and Zan's was 12% off.

Step-by-step explanation:

Since we have given that

In case of Garrick's plant:

Actual height of his plant = 10 mm

Measured height of his plant = 8 mm

In case of Zan's plant :

Actual height of his plant = 100 mm

Measured height of his plant = 88 mm

So, clearly Garrick's plant is shorter than Zan's plant.

Difference in actual height of plants of Garrick and Zan is

$100\ mm-10\ mm=90\ mm$

similarly, difference in measured heights of plants of Garrick and Zan is

$88\ mm-8\ mm\\\\=80\ mm$

Percent error will be

$\frac{90-80}{90}\times 100\\\\=\frac{10}{90}\times 100\\\\=11.11\%$

So, Each millimeter of error results in a 11.11% percent error.

Error in Garrick's plant :

$Actual-Measured\\\\=10-8\\\\=2\ mm$

Percent error is given by

$\frac{2}{10}\times 100\\\\=20\%$

Similarly,

Error in Zan's plant ;

$Actual-Measured\\\\=100-88\\\\=12\ mm$

Percent error is given by

$\frac{12}{100}\times 100\\\\=12\%$

Garrick's measurement was 2 millimeters off and Zan's was 12 millimeters off.

So, Garrick's measurement was 20% off and Zan's was 12% off.
