Answer:

The answer is 72

Step-by-step explanation:

The formula for perimeter is (L+W)x2

So in your case (11+25)x2

Or add all 4 sides of the rectangle up and you have your answer <3

Answer:

3 treatment conditions were compared in the study.

14 individuals participated in the study.

Step-by-step explanation:

Consider the provided information.

Part (A) How many treatment conditions were compared in the study?

There are two sets of degrees of freedom; one for the numerator and one for the denominator.

F ratio is defined as: $df=(df_{\text{Between treatment}}, df_{error})$

The formula for between treatment is: $df_{\text{Between treatment}}=k-1$

Substitute $df_{\text{Between treatment}}=2$ in above formula.

$2=k-1$

$k=3$

Therefore, 3 treatment conditions were compared in the study.

Part (B) How many individuals participated in the study?

The error degree of freedom is $df_{error}=(k-1)(n-1)$

Substitute $df_{error}=26$ and k=3 in above formula.

$26=(3-1)(n-1)$

$26=2(n-1)$

$14=n$

Hence, 14 individuals participated in the study.

X=y<br> x+2y =3<br> Solve using substitution

Zielflug [23.3K]

Answer:

Therefore the Final Solution is

x = 1 and y = 1

Step-by-step explanation:

Given:

$x=y$ ...............Equation ( 1 )

$x+2y=3$ ................Equation ( 2 )

To Find:

x = ?

y = ?

Solution:

Equating Equation ( 1 ) in Equation ( 2 ) we get

$y+2y=3\\\\3y=3\\\\y=\frac{3}{3} \\\\\therefore y =1$

Now Substituting y = 1 in Equation ( 1 ) we get

$x =1\\\\\therefore x=1$

Therefore the Final Solution is

x = 1 and y = 1

9. The figure shows a rectangle with its length and

lora16 [44]

Answer:

875cm^2

Step-by-step explanation:

since opposite sides are equal

3x-y=2x+y

x=2y

y=x/2 ....(i)

thus new length=2x+y

=2x+(x/2) [using (i)]

=(4x+x)/2

l=5x/2 .....(ii)

now,

perimeter=2(l+b)=120cm

l+b=60cm

from figure and using (ii)

[5x/2]+2x-3=60

[5x+4x-6]/2=60

9x-6=120

9x=126

x=126/9

x=14 ..........(iii)

substitute (iii) in (i)

y=14/2

y=7 ...........(iv)

From figure,

length=2x+y [using (iii) and (iv)]

=2x14+7

length=35cm

breadth=2x-3

=2x14-3 ....[using(iii)]

=28-3

breadth=25cm

now,

Area=lxb

=35x25

=875cm^2
