Answers

Answer:

The better buy is The denim shoppe!

Step-by-step explanation:

the denim shoppe price for 3 jeans is $56 and Jeans jam price of 3 jeans is $56.25! $56 < $56.25.

If Ava buys three pairs of jeans from Jeans Jam, it would cost her a total of $56.23. If Ava buys three pairs of jeans from The Denim Shoppe, it would cost her exactly $56. This means that The Denim Shoppe is a better buy...by 23 cents.

Relative frequencies are calculated as _____________.Percentages
Medians
Ranges
Totals

Answers

Relative frequencies are calculated as totals.

Here, we have,

In statistics, relative frequency refers to the proportion or percentage of times a particular value or category appears in a dataset relative to the total number of observations or data points.

It is a way to express the frequency of a value or category in relation to the whole dataset.

To calculate the relative frequency, you divide the frequency (number of times a value or category occurs) by the total number of observations or data points.

This gives you the proportion or percentage of occurrences relative to the total.

For example, if you have a dataset of 100 observations and a specific value appears 20 times, the relative frequency of that value would be 20/100 or 0.20, which is 20%.

So, relative frequencies are calculated as totals by comparing the specific frequency of a value or category to the total number of observations in the dataset.

My algebra math book has this math problem ---> 4a - 3b = 21.i am supposed to figure out if it is true or false. but the thing is, i do not know how to do this so that i can find out if it is true or not.
PLEASE HELP!!!!!

Answers


The value of (4a - 3b) depends on what 'a' and 'b' are.

There are many combinations of 'a' and 'b' that make
(4a - 3b) equal to 21, and a whole bunch of others
that don't.

The equation in your question is not true OR false until you know
what 'a' and 'b' are.  I suspect that right next to this problem in your
math book, it gives you some values for 'a' and 'b'.

Here are a few examples of how to do it:

1).  I tell you that  a=2  and  b=1.
You take those numbers, and write them in place
of 'a' and 'b' in the left side of the equation:

                   4a - 3b

                  4(2) - 3(1)

                    8   -   3  =  5

If  a=2  and  b=1, then the left side of the equation is  5, not 21,
and the equation is false. 

================================

2).  I tell you that  a=5  and  b=4.
You take those numbers, and write them in place
of 'a' and 'b' in the left side of the equation:

                       4a - 3b

                       4(5) - 3(4)

                         20 -  12  =  8

If  a=5  and  b=4, then the left side of the equation is  8, not 21,
and the equation is false. 

=================================

3).  I tell you that  a=6  and  b=1.
You take those numbers, and write them in place
of 'a' and 'b' in the left side of the equation:

                   4a - 3b

                 4(6) - 3(1)

                   24  - 3  =  21

If  a=6  and  b=1, then the left side of the equation is  21,
and the equation is TRUE.

This is not the only possible pair of numbers for 'a' and 'b'
that make the equation true.  There are tons of possibilities.
Look around the question in your book and see if it gives you
values for 'a' and 'b' to test in the equation.

A drop set of 20 gtt/mL is used to run a liter of fluid at 50 gtt/min. How long will it take for the liter to run out?

Answers

Answer: 400 Minutes

Step-by-step explanation: 20 gtt/mL ÷ 50 gtt/min

⇒ 20/50 (gtt/gtt)(min/mL)

= 2/5 min/mL.

For a liter to run out it will take

⇒ 2/5 × 1000 = 400 minutes

Why is 0.04 is 1/10 of 0.4

Answers

is in mathematics means the equal sign
of in mathematics means multiplication

So translating that sentence into an algebraic expression, it would be:

0.04 = 1/10 x 0.4

And that statement is true! Because when you divide a number by 10, you move the decimal over to the left one time.
