Answer:

Step-by-step explanation:

It should only be 5 since there are 4 quartiles in a data set. 20/4=5.

I don't know who told you it was 5.5 but that's not correct.

Answer:

there will be only 5 values in the upper quartile

Step-by-step explanation:

What is -1/3+w=5 3/8 express in simplest form

Elodia [21]

Let's solve your equation step-by-step.
 $\frac{-1}{3}$ +w=5 $\frac{3}{8}$ 
Step 1: Simplify both sides of the equation.
w+ $\frac{-1}{3}$ = $\frac{43}{8}$ 
Step 2: Add $\frac{1}{3}$ to both sides.
w+ $\frac{-1}{3}$ + $\frac{1}{3}$ = $\frac{43}{8}$ + $\frac{1}{3}$ 
w= $\frac{137}{24}$ 

Answer:w=5 $\frac{17}{24}$

Manuel is planting a garden in the shape of a right triangle. The longer leg is 3 ft longer than the shorter leg. The hypotenuse

Gnesinka [82]

Answer:

The length of shorter side of triangle is 9 cm

The length of longer side of triangle is 12 cm

The length of hypotenuse is 15 cm

Step-by-step explanation:

Given as , for the garden in the shape of right triangle :

Let The length of shorter side = B = x ft

So , the length of longer side = P = ( x + 3 ) ft

And The hypotenuse length = H = ( 3 + P ) ft

I.e H = ( 3 + x + 3 ) ft = ( x + 6 ) ft

Now from Right angled Triangle method

Hypotenuse² = Perpendicular² + Base²

Or, ( x + 6 )² = ( x + 3 )² + x²

Or, x² + 12 x + 36 = x² + 6 x + 9 + x²

Or, - x² + 6 x + 27 = 0

Or, - x² + 9 x - 3 x + 27 = 0

Or, - x ( x - 9 ) - 3 ( x - 9 ) = 0

So, ( x - 9 ) ( - x - 3 ) = 0

∴ x = 9 , - 3

So, shorter length = x = 9 cm

The longer length = x + 3 = 9 + 3 = 12 cm

The hypotenuse length = x + 6 = 9 + 6 = 15 cm

Hence The length of shorter side of triangle is 9 cm

The length of longer side of triangle is 12 cm

And The length of hypotenuse is 15 cm . Answer
