Answer:
The answer to your question is letter B
Step-by-step explanation:
Data
length = 12 in
width = 8 in
height = 16 in
surface area = ?
Formula
Surface area = 2( length x width) + 2(length x height) + 2((width x height)
Substitution
Surface area = 2(12 x 8) + 2(12 x 16) + 2(8 x 16)
Simplification
Surface area = 256 + 384 + 102
Result
Surface area = 832 in²
Answer:
7 weeks
Step-by-step explanation:
500-200=300. 300 divided by 40 is 7.5 so 7 weeks
Answer:
Standard deviation of a normal data distribution is a measure of data dispersion.
Step-by-step explanation:
Standard deviation is used to measure dispersion which is present around the mean data.
The value of standard deviation will never be negative.
The greater the spread, the greater the standard deviation.
Steps-
1. At first, the mean value should be discovered.
2.Then find out the square of it's distance to mean value.
3.Then total the values
4.Then divide the number of data point.
5.the square root have to be taken.
Formula-
SD=
Advantage-
It is used to measure dispersion when mean is used as measure of central tendency.
1. Each term in this polynomial has a common factor of
:

2. Not sure what the "vertical method" is, but I would guess it refers to some way of visualizing the distributive property.



3. You can use the same approach as in (2), or recall that
:


4. Recall that a difference of squares can be factored as
. So


Answer:
$4.57. Hope this helps :)
Step-by-step explanation:
20+5=25
then you do
25-3.67= $21.33
you then divide that by the number of pounds she bought.
21.33/4= 5.3325
round that to the hundreths place and you get $5.33
so she paid $5.33 for a pound
