Answer:

It forms from sandstone that has come into contact with deeply buried magmas. Quartzite looks similar to its parent rock. The best way to tell quartzite from sandstone is to break the rocks. Sandstone will shatter into many individual grains of sand while quartzite will break across the grains.

What was the average of diameters (cm) for the Willapa Bay urchins sampled before the hunt? (Type just the number rounded to the

Otrada [13]

Answer:

See Explanation

Explanation:

The question is incomplete as the diameters of the Willapa Bay urchins were not given.

However, I'll give a general way to solve this problem.

Average is calculated using:

$Average = \frac{\sum x}{n}$

i.e. Sum of all diameters divided by the number of bay urchins.

The diameter of urchins is usually between 6cm to 12cm; So, I will assume the following diameters for 10 urchins.

10cm, 8cm, 10cm, 7cm, 9cm, 10cm, 6cm, 10cm,8cm, 8cm

Using the above data, the average is:

$Average= \frac{10+8+10+7+9+10+6+10+8+8}{10}$

$Average= \frac{86}{10}$

$Average= 8.6$
