Answer:

12.15

Step-by-step explanation:

3/20 = 15/100 = 0.15

Explanation:

Decimals are way of writing fractions which have denominators that are powers of 10

0.3 = 3/10

0.38 = 38/100

0.384 = 384/1000

etc

Find an equivalent fraction for 3/20

3/20× 5/5 = 15/ 100

This can now be written as

0.15

and the remaining whole twelve you are to add

so it would be 12.15

Answer:

12.15

Step-by-step explanation:

It is 12.15 because you have 12, right? 3 divided by 20, gives you 15.

Another way you can use to find the answer is taking 3/20 from 12 3/20, and then 3/20 equals 15/100. As a decimal it will be 12.15

Hope this helps!

Answer:

Mean. It includes all data points.

Step-by-step explanation:

-We first need to calculate the mean, median and mode then compare our values:

#Mean:

$\bar x=\frac{1}{n}\sum{x_i}\\\\=\frac{1}{10}\sum{778+783+784+786+790+804+807+810+819+823}\\\\=\frac{1}{10}\times \\\\=798.40$

#The median is the middlemost data point in a lsit data:

778,783,784,786,790,804,807,810,819,823

-Since our data points is an even number, the median number is calculated as:

$median=\frac{1}2}\sum{5^{th}+6^{th}}\\\\=0.5[790+804]\\\\=797.00$

#Mode is the data point with the highest frequency:

-Since there's no number appearing more than once, our set has no mode.

#Since our data set has no outliers and is not a skewed distribution, the mean will be the best measure as it includes all data points

What does -5.4+9.7 equal?

tatiyna

Oh gurly!!!! Just use a calculator but I’ll answer this one for you okay? Now how I’d do it without a calculator is subtract. Subtract if it asks you to add and add if it asks for subtraction.. it may be confusing but I’ll explain. 9.7-5.4=4.3

When you add a negative to a positive it subtracts the positive.
