A park ranger wanted to compare the length of largemouth bass in two different lakes in a park. He
randomly pulled 20 largemouth bass from each lake and measured the length of each fish. The
table shows the mean length and the mean absolute deviation (MAD) of the largemouth bass in
each lake

Calculate the means-to-MAD ratio. Can the park ranger conclude that the largemouth bass in Lake
2 are generally longer than the ones in Lake 1?
Select from the drop-down menus to correctly answer the question.
The park ranger -
conclude that Lake 2 generally has longer largemouth bass
because the distributions of lengths in the two lakes are -

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

570, the answer is 570, hope it
