Your answer to the first one is incorrect.

We can cut the plan into two figures, a rectangle with side lengths of 4 cm and 5 cm and a rectangle with side lengths of 1 and 2 cm.

Perimeter of a Rectangle:

P = 2(l + w)

P = 2(4 + 5)

P = 2(9)

P = 18

Perimeter of a Rectangle:

P = 2(l + w)

P = 2(2 + 1)

P = 2(3)

P = 6

Add up the perimeters:

18 + 6 = 24

So the total perimeter is 24.

For the 2nd one, your answer is also incorrect.

We multiply 5 to the perimeter of the plans:

5 * 24 = 120

Not sure what the third one is asking.

For the fourth one we just multiply 'k' to the perimeter:

24 * k = 24k

A TV report conducted a survey of 947 people in New York City and found that 35% of the population believe that the Yankees will
garik1379 [7]

Answer:

35\% represents the sample proportion of the population

Step-by-step explanation:

From the question we are told that

   The sample size is  n  = 947

   The proportion of the population that believes that the Yankees will miss the playoffs this year is    k = 35\% = 0.35

From the question we are told the confidence level is  97%

   The lower limit of the confidence level is a = 28%

    The upper limit of the  b = 42%

Generally the sample proportion of this population is mathematically represented as

         \^ p = \frac{a+ b}{2}

=>      \^ p = \frac{28 + 42 }{2}

=>      \^ p = 35\%

Hence  35\% represents the sample proportion
