The brain volumes ​(cm cubedcm3​) of 50 brains vary from a low of 922922 cm cubedcm3 to a high of 14961496 cm cubedcm3. use the
vesna_86 [32]
The range rule of thumb is that the range is four times the standard deviation. The range in this case is 922 cubic cm to 1496 cubic cm, i.e., 574 cubic cm.
Therefore, according to the rule, the standard deviation is 574 cubic cm/4 = 
143.5 cubic cm. The actual standard deviation is 161.7 cubic cm. The difference is 161.7 - 143.5 = 18.2. Since this is greater than 15 cubic cm, the rule in this case is not accurate.

I need help ASAP!!!!!!!!
4vir4ik [10]

Answer:

Step-by-step explanation:

1st rectangle has an area of: h - horizontal sections * l - lateral sections.

A1 = 10 * 10 = 100 units squared

But only a fraction of them are colored.

72 / 100 are colored in the 1st rectangle.

The second has an area of: A2 = 10 * 1 = 10 units squared, but one row in the 2nd rectangle is the same as 10 units in the 1st so the area is still 100 units squared.

But the colored sections are 2/10 or 20/ 100.

Now we subtract 72/100 - 20/100 = 52/100 = 26/50 = 13/25 = 0.52 A
