Answer:
![Range =24F- (-9F)=24+9F=33F](https://tex.z-dn.net/?f=Range%20%3D24F-%20%28-9F%29%3D24%2B9F%3D33F)
So then for the question :"What is the range between the high and low temperatures of the day?" We can answer 33 F
Step-by-step explanation:
Previous concepts
The range of a set of data is "the difference between the largest and smallest values of this dataset". Using this definition the formula for the range is:
![Range =Maximum -Minimum](https://tex.z-dn.net/?f=Range%20%3DMaximum%20-Minimum)
We assume that the minimum value for the temperature on this case is -9F , so then:
![Minimum =-9 F](https://tex.z-dn.net/?f=Minimum%20%3D-9%20F)
And we assume that the maximum value occurs at the afternoon, and on this case then:
![Max =24 F](https://tex.z-dn.net/?f=Max%20%3D24%20F)
Solution to the problem
And then using the definition of range we got:
![Range =24F- (-9F)=24+9F=33F](https://tex.z-dn.net/?f=Range%20%3D24F-%20%28-9F%29%3D24%2B9F%3D33F)
So then for the question :"What is the range between the high and low temperatures of the day?" We can answer 33 F
Answer:
The first one
Step-by-step explanation:
Answer:
![\frac{3}{2d}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2d%7D)
Step-by-step explanation
our given expression is = ![\frac{12}{7d}-\frac{3}{14d}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B7d%7D-%5Cfrac%7B3%7D%7B14d%7D)
In order to simplify first of lets make the denominator of both the fractions same by multiplying and dividing with some number.
Lets multiply and divide our first fraction by 2 in order to make denominator of both the fractions same.
= ![\frac{2}{2}\frac{12}{7d}-\frac{3}{14d}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B2%7D%5Cfrac%7B12%7D%7B7d%7D-%5Cfrac%7B3%7D%7B14d%7D)
=![\frac{24}{14d}-\frac{3}{14d}](https://tex.z-dn.net/?f=%5Cfrac%7B24%7D%7B14d%7D-%5Cfrac%7B3%7D%7B14d%7D)
Now taking LCM of both fractions
= ![\frac{24-3}{14d}](https://tex.z-dn.net/?f=%5Cfrac%7B24-3%7D%7B14d%7D)
Simplifying further
=![\frac{21}{14d} = \frac{3}{2d}](https://tex.z-dn.net/?f=%5Cfrac%7B21%7D%7B14d%7D%20%3D%20%5Cfrac%7B3%7D%7B2d%7D)
So out correct answer is ![\frac{3}{2d}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2d%7D)
Don’t know I’m just answering thus because it doesn’t let me ask a question unless I answer a random question. Sorry
Answer: 121 mph
Step-by-step explanation: First, I did 6 x 7, and I got 42. Then I did 42 + 79, and I got 121 mph as my answer.
