The midpoint lines are half the opposite side length.

Line DE is given as 7 , So Line F = 7 x 2 = 14

Line EF is given as 12, so Line D = 12 x 2 = 24

Line DF is given as 16, so line E = 16 x 2 = 32


The perimeter is the sum of the 3 sides:

Perimeter = 14 + 24 + 32 = 70

Pachacha [2.7K]
Compare them by making them like terms.
4/6 x2/2=8/12
4/6=8/12 so when compared to 4/12,
4/6 > 4-12

All members of our painting team paint at the same rate. If $20$ members can paint a $4800$ square foot wall in $36$ minutes, th
Softa [21]

Answer:

It takes 70 minutes for 9 team members (painting 60 sq ft per minute) to paint a 4200 sq ft wall.

Step-by-step explanation:

According to the situation the calculation is shown below:-

= \frac{4800}{20}

= 240 sq ft each member of the team in 36 minutes

= \frac{240}{36}

= 6.67 sq ft each member of the team within 1 minute

= 6.67\times 9

= 60 sq ft for every 9 team members in one minute

= \frac{4200}{60}

= 70 minutes (or 1 hour and 10 minutes)

Hence, the 70 minutes is taken for 9 team members

Zigmanuir [339]

Answer:

u = 4.604 , s = 2.903

u' = 23.025 , s' = 6.49

Step-by-step explanation:

Solution:

- We will use the distribution to calculate mean and standard deviation of random variable X.

- Mean = u = E ( X ) = Sum ( X*p(x) )

 u = 1*0.229 + 2*0.113 + 3*0.114 + 4*0.076 + 5*0.052 + 6*0.027 + 7*0.031 + 8*0.358.

 u = 4.604

- Standard deviation s = sqrt ( Var ( X ) = sqrt ( E ( X^2) + [E(X)]^2

 s = sqrt [ 1*0.229 + 4*0.113 + 9*0.114 + 16*0.076 + 25*0.052 + 36*0.027 + 49*0.031 + 64*0.358 - 4.604^2 ]

s = sqrt ( 8.429184 )

s = 2.903          

- We will use properties of E ( X ) and Var ( X ) as follows:

- Mean = u' = E (Rate*X) = Rate*E(X) = $5*u =

               u' = $5*4.605

               u' = 23.025

- standard deviation = s' = sqrt (Var (Rate*X) ) = sqrt(Rate)*sqrt(Var(X)) = sqrt($5)*s =

               s' = sqrt($5)*2.903

               u' = 6.49
