One pack = 14 ounces.
She has 8 packs.
If one candle takes up 7 ounces, then each pack can create 2 candles.
2 x 8 = 16. In total, she can make 18 candles.
I'm going to do this problem with mathematical equations (I chose x to represent the first, y as the second, and z as the third)
so according to the first sentence, x+y+z=270
the second sentence is saying x+y=z+98
and the third sentence says z-47=x
I would first plug x in to my middle equation
(z-47)+y=z+98
then add 47 to both sides to get z+y=z+145
In this case we are lucky because as we go to subtract z they cancel out and we get y=145
Now plug y and x (in terms of z) into the first equation
(z-47)+145+z=270
subtract 47 from 145 to get 98
subtract that from 270 to give you z+z=172
simplify 2z=172
divide by 2 to get z=86
Now go back and plug in z to the bottom equation,
86-47=x so x is equal to 39
Overall we got x=39, y=145 and z=86
To make sure these answers are correct we want to plug the back into our original equations.
39+145+86=270 True!
39+145=184=86+98 True!
and finally 86-47=39 True!
So we know that these numbers are correct
*Just so you know it doesn't really matter which equation you plug in you substituted values into, or which one you solve for first, it's all just a matter of preference....
Answer:
The given statement describe inferential statistics.
Step-by-step explanation:
Descriptive Statistic:
- It helps us to summarize a given data set.
- It could describe the entire population or a sample from the population.
- There are two types of descriptive measures: measures of central tendency and measures of variability
- Central Tendency: Mean, mode, Median
- Measure of Viability: Standard Deviation, Variance, Range, Interquartile range
Inferential Statistic:
- It s the process of estimating population parameter with the help of a sample from the population.
- A random sample from the population is used to describe the population with the help of sample statistic.
Given Scenario:
"Based on a sample of 170 truck drivers, there is evidence to indicate that, on average, independent truck drivers earn more than company-hired truck drivers."
Thus, this is an example of a inferential statistics as a sample was used to estimate the population.
Here,
Sample:
Sample of 170 truck drivers
Population:
All truck drivers.
With the help of a sample, we approximated the population, thus, this statement describe inferential statistics.
You can reduce the expression by cancelling out common factor
