Answer:

Median: 33

Third Quartile: 39

Interquartile Range:

Step-by-step explanation:

25  25  25  25  29  29  31  31  33  33  37  37  38  38 42  42  43  43

The median is the middle, so the median is 33 (there's two but both are 33 so that averages to 33)

Third Quartile: I don't know how to explain it I forgot how to do this since I did it last year (I used the internet oops)

Interquartile Range: 11

The municipal swimming pool in Charlotte North Carolina has a three different ways of paying for individual open swimming. Nick
bija089 [108]

Answer:

1. a Early Pay: y = 45

b. Deposit Plus: y = 12.00 + 4.00x

c. Daily Pay: y = 6.00x

2.  Early pay = $25

  Deposit Plus = 12.00 + 4.00(4) =  12.00 + 16.00 = $28.00

Daily Pay = 6.00(4) = $24.00

Daily Pay is the cheapest one.

3. Early Pay = $45

Deposit Plus = 12.00 + 4.00(8) = 12.00 + 32.00 = $44.00

Daily Pay = 6.00(8) = $48.00

Deposit Plus is the cheapest one.

4. Early Pay = $45

Deposit Plus = 12.00 + 4.00(12) = 12.00 + 48.00 = $60.00

Daily Pay = 6.00(12) = $72.00

Early Pay is the cheapest one.

5.  Since Jane likes to swim most days, it would be cheaper for her to do the Early pay option, because the price is a one time fee and she can swim every day.

Since Suzy doesn't really like to go swimming and might only go a couple times, it would be best for her to do the daily pay, that way she didn't spend any money up front if she doesn't swim at all.

Solve for x x - 1 2 = 4
Firlakuza [10]

Hey!

--------------------------------

Solution #1:

x - 12 = 4

x + (-12) = 4

x + (-12) + 12 = 4 + 12

x = 16 ✔

--------------------------------

Solution #2:

x - 1/2 = 4

x + (-1/2) = 4

x + (-1/2) + 1/2 = 4 + 1/2

x = 4 1/2 ✔

--------------------------------

Solution #3:

x - 1.2 = 4

x + (-1.2) = 4

x + (-1.2) + 1.2 = 4 + 1.2

x = 5.2 ✔

--------------------------------

Hope This Helped! Good Luck!

PLEASE HELP WILL GIVE LOTS OF POINTS!!!
malfutka [58]

Answer:

yes

Step-by-step explanation:

Hey There!

We can find the answer by using proportions of the other sides

What i mean by this is if ADs proportion to AE is the same as BDs proportion to EC then DE is proportional to BC

6/4=1.5

9/6=1.5

Therefore DE is proportional (or similar) to BC
