A scientist took a sample of spiny lumps (a type of fish) and found this sample to have a mean length of 2.5 cm. It is estimated that 16% of spiny lumps have a length of 4 cm or greater. What is the standard deviation of the lengths of this sample of spiny lumps?

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
