Answer:

This is a geometric sequence and the common ratio is equal to ⅛.

Step-by-step explanation:

The sequence is a geometric sequence because if we multiply a term with ⅛, we will get the consecutive term in the sequence.

The common ratio = 8/64 = 1/8

Thus, it has a common ratio of ⅛.

If we multiply 64 by ⅛, we would have the next term in the sequence. Thus:

64 × ⅛ = 64/8 = 8

K=mv^2/2 solve for v

matrenka [14]

Answer: $v=\sqrt[]{\frac{2K}{m} }$

Step-by-step explanation:

$K=\frac{mv^2}{2}$

First, multiply by 2 to get rid of the 2 in the denominator. Remember that if you make any changes you have to make sure the equation keeps balanced, so do it on both sides as following;

$2*K=\frac{mv^2}{2}*2$

$2K=mv^2$

Divide by m to isolate $v^2$ .

$\frac{2K}{m}=\frac{mv^2}{m}$

$\frac{2K}{m} =v^2$

To eliminate the square and isolate v, extract the square root.

$\sqrt[]{\frac{2K}{m} }=\sqrt[]{v^2}$

$\sqrt[]{\frac{2K}{m} }=v$

let's rewrite it in a way that v is in the left side.

$v=\sqrt[]{\frac{2K}{m} }$

Assume that we are interested in the average length of 1015 fishes in Square Lake, WI. Also assume that all information for all

zimovet [89]

Answer is given below

Step-by-step explanation:

given data

average length of all 1015 fishes = 98.06 mm

randomly selects 50 fishes average length = 101.04 mm

solution

When we get here, we mean to measure, so here we measure a fish in a square lake.
And the variable means that a fish varies from fish to fish, so the length of the fish in the squares
parameter mean that all individuals in the population so the parameter is average length of all 1015 fish in square lake
statics is selct of individual in sample so statistic is average length of random sected so fish in square lake
