Answer:
Step-by-step explanation:
Both $94 and 12% were rounded down, so the estimate will be less than the actual amount.
Canceling units is also called unit analysis.
This is also called dimensional analysis.
What is a unit of analysis in statistics?
- The unit of analysis is the entity that you're analyzing. It's called this because it's your analysis (what you want to examine) that determines what this unit is, rather than the data itself.
- Because it is the analysis you do in your study that determines what the unit is.
- For instance, if you are comparing the children in two classrooms on achievement test scores, the unit is the individual child because you have a score for each child.
For example -
1 ft = 12 in
3 ft = ![3 ft * \frac{12 in }{1 ft}](https://tex.z-dn.net/?f=3%20ft%20%2A%20%5Cfrac%7B12%20in%20%7D%7B1%20ft%7D)
3 ft = ( 3 * 12 ) in ⇒ 36 in

Answer:
D. 13
Step-by-step explanation:
well since it's a quadratic equation, it can be written in the form of ax²+bx+c=0. So we have a=1, b=b and c= -30. Also the roots are given by the equation-
x= -b±
/2a. So all I did was put the number from the choices which would satisfy the sqrt part and that turned out to be 13 since
=
= 17. So b=13.
Answer:
The grapes are more expensive than the green grapes.
Step-by-step explanation:
GRAPES: If you divide $20.72 by 7, to get one bag of grapes instead of seven, you get $2.96/bag.
GREEN GRAPES: If you divide $8.46 by 3, to get one bag of green grapes instead of three, you get $2.82/bag.
$2.82 is less than $2.96, therefore, the grapes are more expensive than the green grapes.
