When each operation described below is performed to both sides of an inequality, is the inequality sign preserved or reversed? Operations: preserved: or reversed: Add 3 Subtract -3 Multiply by 3 Divide by -3

Answers

Answer 1

Answer:

Add 3 -> Preserve

Subtract -3 -> Preserve

Multiply by 3 -> Preserve

Divide by -3 -> Reverse

Step-by-step explanation:

Required

When is an inequality reversed or preserved

There are only two operations that can reverse an inequality, and they are:

Multiplying the inequality by a negative numberDividing the inequality by a negative number

Other operations will preserve the inequality.

So, the solution is as follows:

Add 3 -> Preserve

Subtract -3 -> Preserve

Multiply by 3 -> Preserve

Divide by -3 -> Reverse

Answer:

1/3

If 4 are snickers and 8 are mars bars then 4/12 would be snickers so when you simplify 4/12 you get 1/3.

What is a box plot?

In Mathematics, a box plot is sometimes referred to as a box-and-whisker plot and it can be defined as a type of chart that is used for the graphical or visual representation of the five-number summary of a data set with respect to locality, skewness, and spread.

By using the box-and-whisker plot (box plot) shown in the image attached above, the five-number summary for the given data set include the following:

Minimum = 2.First quartile = 4.Median = 6.Third quartile = 8.Maximum = 11.

By critically observing the box-and-whisker plots (see attachment), we can logically deduce that it represents all of the five-number summary for 2, 3, 5, 5, 6, 7, 8, 8, and 11.

Which best describes the probability of the rolling a 7 on a number cube that is numbered from 1 through 6

Answers

Answer:

[tex]\huge\boxed{\text{Impossible}}[/tex]

Step-by-step explanation:

To find the probability of something happening, we find all the outcomes that can happen, find all the outcomes in which our criteria is met, and set that up as a fraction, where it's criteria met/total possible outcomes.

When we roll a 6-sided die, we will have 6 possible outcomes that we can roll.

1, 2, 3, 4, 5, and 6.

We can not roll anything except these 6! Since a die only has 6 sides, numbered 1-6, we will only roll these numbers.

7 is not in this list! It is impossible to roll a 7 on a die that only has 6 sides. Since 7 isn't even possible, it would be impossible to get a 7 on a 6-sided die.

WHOEVER ANSWERS IS CONSIDERED THE BRAINLIEST QUESTION: Faye has a bag that contains 10 red, 13 blue, 16 white, 10 green, and 11 black marbles. She pulls a marble out of the bag without looking. What is the probability Faye pulls out a white marble.
SHOW WORK!

Answers

Answer:

Faye's probability of pulling out a white marble is 3/80.

Step-by-step explanation:

To find the probability, we must first add everything up.  10 + 13 + 16 + 10 + 11 = 60 marbles.  Now we divide 60 by the amount of white marbles there are.  60 ÷ 16 = 3.75% or 3/80.  Therefore, the probability of Faye pulling out a white marble is 3/80.

A collection of coins contains a total of sixteen dimes and quarters. It is worth $2.20 in all. How many dimes are in the collection?

Answers

Answer:

  12 dimes

Step-by-step explanation:

Let q represent the number of quarters. Then the number of dimes is 16-q and the total value is ...

  0.25q +0.10(16 -q) = 2.20

  0.15q +1.60 = 2.20 . . . . . . . simplify

  0.15q = 0.60 . . . . . . . . subtract 1.60

  q = 4 . . . . . . . . . . . divide by 0.15

  16-q = 12

There are 12 dimes in the collection.

Step-by-step explanation:

5) r=v/r

r= 15,600 gals ÷ 390 mins

r= 40 gals/min

6) r=v/t

r= 1000mm ÷ 8 hrs

r= 125 mm/hr
