Find the length of each trapezoid.

Find The Length Of Each Trapezoid.

Answers

Answer 1

Answer:

EF = 27

Step-by-step explanation:

(x + 34)/2 = 2x - 13

x+ 34 = 4x - 26

3x = 60

x = 20

EF = 2(20) -13 = 27

Answer 2

Answer:

11.  EF = 27

Step-by-step explanation:

11.

Median of a trapezoid:

2x - 13 = 20 + x + 14

                    2

2(2x - 13) = 20 + x + 14

4x - 26 = 34 + x

4x - x = 34 + 26

3x = 60

x = 20

EF = 2x - 13

EF = 2(20) - 13

EF = 40 - 13

EF = 27

Answer:

a= $54764.26

Step-by-step explanation:

r=R/100

r=4.5/100

r=0.045 rate per year

A = P(1 + r/n)nt

A = 10,000.00(1 + 0.045/4)(4)(38)

A potato chip company produces a large number of potato chip bags each day and wants to investigate whether a new packaging machine will lower the proportion of bags that are damaged. The company selected a random sample of 150 bags from the old machine and found that 15 percent of the bags were damaged, then selected a random sample of 200 bags from the new machine and found that 8 percent were damaged. Let p^O represent the sample proportion of bags packaged on the old machine that are damaged, pˆN represent the sample proportion of bags packaged on the new machine that are damaged, pˆC represent the combined proportion of damaged bags from both machines, and nO and nN represent the respective sample sizes for the old machine and new machine.

Required:
Have the conditions for statistical inference for testing a difference in population proportions been met?

Answers

Answer:

The conditions for the approximation have been met

Step-by-step explanation:

Random samples on both cases  and

p∧o proportion of bags packaged on the old machine that are damaged

p∧n sample proportion of bags packaged on the new machine that are damaged

p∧c  =  ( p∧o + p∧n ) / (nO + nN )  

p∧o = 15 %      p∧o =  0,15         nO = 150

p∧o *  nO = 0,15 *150          p∧o *  nO = 22,5

p∧n  = 8 %      p∧n  = 0,08     nN = 200

p∧n*nN  = 0,08 * 200     p∧n*nN  = 16

Both  p∧n*nN  and   p∧o *  nO    are bigger than 5

Therefore both samples are big enough for the approximation of the binomial distribution to normal distribution

Mr Baxter deposits 2,000 in an account that earns %5 simple interest how much is mr Baxter investment after 8 years?

Answers

Answer:

$2,800

Step-by-step explanation:

The formula for simple interest is I = PRT, where I is the interest (earned or paid), P is the principal amount invested/borrowed, R is the rate in decimal form, and T is the time in years.

I = (2000)(0.05)(8)

I = $800

Then we add that to the principal to get $2,800

Multiply 35 times 8, which you’ll get 280

20=h
Therefore h=20ft is your answer <3

Answer:

h = 20 ft

Given,

Volume = 5600 sq.ft

Length = 35 ft

Width = 8 ft

Therefore,

By the problem,
