D.
30
Find the median of the data. A. 25 B. 27 - 1

Answers

Answer 1
Answer: Both A.25 and D.30 are the median

1.First you need to put the numbers in order

15,15,20,25,25,30,30,35,45

2.You then need to cross one off each side as you go down (As below)

15,20,25,25,30,35
20,25,25,30
25,30

3.After you take all the numbers off you stop when there are no numbers to take off from both ends 

25,30

4.You are then left with these two median numbers so your answer is 25 and 30

I hope this explains it for you if you need any other information then please ask i wouldn't mind helping

Simplify -62 ÷ 12 - 2(-7).

-17
35
11
-35

Answers

I don't know if you know something called PEMDAS

Parentheses
Exponent
Multiply
Divide
Add
Subtract

So you would do the -2(-7) first giving you 14

So now we have -62/12 +14

now you would do -62/12 giving you -5.16666667

and now the equation is -5.16666667 + 14 = 8.83333333

I know for a fact, being in Calculus Honors, that what I did to simplify is correct. Using the Order of Operations, or PEMDAS (Commonly remebered as "Please Excuse My Dear Aunt Sally". It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction".) to simplify this answer is necessary.

If your teacher wrote this problem please inform him or her of Order of Operations before your classmates use it even though its wrong.

Find the distance between (3,4) and (4,-6).

Answers

Answer:

The answer is

√(101)

Step-by-step explanation:

The distance between two points can be found by using the formula

d = \sqrt{ ({x1 - x2})^(2) + ({y1 - y2})^(2) } \n

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(3,4) and (4,-6)

The distance between them is

d = \sqrt{ ({3 - 4})^(2) + ({4 + 6})^(2) } \n = \sqrt{ ({ - 1})^(2) + {10}^(2) } \n = √(1 + 100 ) \: \: \: \: \: \: \: \: \: \n = √(101) \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:

We have the final answer as

√(101)

On a recent trip to the convenience store, you picked up 4 gallons of milk, 6 bottles of water and 5 snack size bags of chips. You total bill before tax was $ 27.2. If a bottle of water costs twice as much as a bag of chips, and a gallon of milk costs $1.80 more than a bottle of water, how much does each item costHow much does a snack size bag of chips cost?


How much does a bottle of water cost?


How much does a gallon of milk cost?

Answers

Answer:

Cost of a snack size bag of chips = $0.8

Cost of a water bottle = $1.6

Cost of a gallon of milk = $3.4

Step-by-step explanation:

Let the cost of water bottle = $a

Cost of 1 gallon milk = $b

and cost of 1 bag of chips = $c

So, cost of 4 gallons of milk, 6 bottles of water and 5 bags of chips = $(4b + 6a + 5c)

4b + 6a + 5c = 27.2 -----(1)

Cost of one water bottle = 2 × cost of one bag of chips

a = 2c -----(2)

A gallon of milk = cost of water bottle + $1.80

b = a + 1.8

From equation (2)

b = 2c + 1.8 -----(3)

Now we substitute these values from equations (2) and (3) in equation (1)

4(2c + 1.8) + 6(2c) + 5c = 27.2

8c + 7.2 + 12c + 5c = 27.2

25c = 27.2 - 7.2

c = (20)/(25)

c = $0.8

From equation (2)

a = 2×0.8

a = $1.6

From equation (3)

b = 2(0.8) + 1.8

b = 1.6 + 1.8

b = $3.4

Therefore, cost of a snack size bag of chips = $0.8

Cost of a water bottle = $1.6

Cost of a gallon of milk = $3.4
