Answer:

A = -24

Step-by-step explanation:

A negative over a positive makes a negative and 24 divided by 3 is 8, so -24 divided by 3 is -8 making A/-24 the correct answer.

I’m pretty sure it’s A bc you multiply the three to leave the a alone and you multiply the 3 to -8 and that equals -24

data set A is {30, 45, 32, 50, 33, 40, 44, 32}. Data set B is {28, 43, 30, 48, 35, 42, 46, 34}. which statement best compares th

Answer:

the mean in set B is equal to the mean in set A (option C)

Question:

The question is incomplete as the answer choices were not given.Let's consider the following question:

Data set A is {30, 45, 32, 50, 33, 40, 44, 32}. Data set B is {28, 43, 30, 48, 35, 42, 46, 34}. which statement best compares the two data sets?

a) median for set A is equal to the median for set B

b) Range for set A is greater than range for set B 

c) The mean in set B is equal to the mean in set A

Step by step explanation:

We can describe a data set using four ways:

Center, spread, shape and unusual features.

Let's consider the center and spread.

Center: This is the median of the distribution.

Spread: This is the variation of the data set. If the range is wide, the spread is larger and If the range is small, the spread is smaller.

Rearranging the data set:

A = {30, 32, 32, 33, 40, 44, 45, 50}

B = {28, 30, 34, 35, 42, 43, 46, 48}

From the data:

The median for set A = (33+40)/2 = 73/2= 36.5

The median for set B = (35+42)/2 = 77/2= 38.5

Range = highest value - lowest value

The data ranges from 30 to 50 (range = 20) for A 

The data ranges from  28 to 48 (range = 20) for B

Mean for set A = (30+32+32+33+40+4445+50)/8 = 306/8 = 38.25

Mean for set B = (28+30+34+35+42+43+46+48)/8= 306/8 = 38.25

In both data set the mean is equal to 38.25.

Therefore the statement that best compares the two data sets is the mean in set B is equal to the mean in set A (C)

2 1/2kg cost £2.50. How much for 1kg?
TEA [102]
<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ Figure out what you would need to do to get from 2.5kg to 1kg

You would need to divide by 2.5

Just divide the cost by this value:

2.5/2.5 = 1

1kg would cost £1.00

<h3><u>✽</u></h3>

➶ Hope This Helps You!

➶ Good Luck (:

In the equation below, for what value of c does x = 4?<br> 1 / (2x + 4) = 3x-c
rodikova [14]

Answer:

Option D.

Jenn's answer is not correct. She got it substituting c=4 into the equation and solving for "x".

Step-by-step explanation:

Given the following equation:

\frac{1}{2}(2x + 4) = 3x-c

Since you need that x=4, you hace to substitute that value into the equation:

\frac{1}{2}(2(4) + 4) = 3(4)-c

Now you need to solve for "c":

\frac{1}{2}(8 + 4) = 12-c\\\\\frac{12}{2}= 12-c\\\\6=12-c\\\\c+6=12\\\\c=12-6\\\\c=6

Therefore for a  a value of c=6, you get x=4

Then, the you can identify that the correct answer is the one given in the Option D.

Jenn made a mistake, because she substituted c=4 into the equation and then solve for "x":

\frac{1}{2}(2x + 4) = 3x-(4)\\\\x+2=3x-4\\\\2+4=3x-x\\\\6=2x\\\\\frac{6}{2}=x\\\\x=3
