Here is a list of numbers.
32 29 30 37 34
34 33 31
Tanya thinks that to work out the median, she simply needs to find
the middle number. So she says that “37" is the median for this list of numbers.
Tanya's answer is not correct.
a) Describe what is wrong with her method.
b) Work out the median of the numbers in the list.

Answers

Answer 1

Step-by-step explanation:

32 29 30 37 34 34 33 31

a) Describe what is wrong with her method.

There two likely reasons why her answer is not correct;

- She did not arrange the numbers in order.

- The middle position belongs to two numbers, instead of finding the average she picked only one

b) Work out the median of the numbers in the list.

Arranging the numbers in ascending order;

29, 30, 31, 32, 33, 34, 34, 37

32 and 33 are both in the middle. The average of both numbers is the median

Median = (32 + 33) / 2 = 65 / 2 = 32.5

Two county fairs are nearby, and Marc is trying to determine which one would be best to attend. Both fairs sell tickets for rides, food, games and more. Polk County Fair is charging a $10 entry fee, and each ticket costs $2.50. Pinellas County Fair isn't charging an entry fee, but each ticket costs $3.

Answers

Answer:

Step-by-step explanation:

It depends on how many tickets Marc will need.

For t tickets, Polk costs 10+2.5t and Pinellas costs 3t.

10+2.5t = 3t

t = 20

If Marc needs fewer than 20 tickets, Pinellas is the more economical choice.

Make x the subject of h = 4(x + 3y) + 2
You may use the flowchart to help you if you wish.

Answers

Answer:

x = {(h-2)/4} -3y

Step-by-step explanation:

Here, we want to make x the subject of the formula

h = 4(x + 3y) + 2

h-2 = 4(x + 3y)

divide both sides by 4

(h-2)/4 = x + 3y

x = (h-2)/4 -3y

Answers

Answer:

x = 3

y = 2

Step-by-step explanation:

5x - 3 = 6y

5x + 3 = 9y

y = 5/6 x - 1/2

5x + 3 = 15/2 x - 9/2

-5/2 x + 15/2 = 0

-5/2 (x - 3) = 0

x = 3

Answer:

x = 3

y = 2

Step-by-step explanation:

because it's a rectangle, opposite sides are equal

AD = BC

AB = DC

so we can use their measures to create a system of equations:

5x + 3 = 9y

5x - 3 = 6y

if we multiply the first equation by -1 we can eliminate the x-values:

-(5x + 3 = 9y)

-5x - 3 = -9y

+ 5x - 3 = 6y

-6 = -3y

y = 2

If y = 2 then BC = 12 and we can set up this equation:

12 = 5x - 3

15 = 5x

3 = x
