Rember a variable without a coefficient or number is 1 so 1×2+3 1×2=2 2+3=5
Answer:
<em>The freezing point of water increases by 0.0001 degrees Fahrenheit when the altitude increases by 1 foot.</em>
Step-by-step explanation:
The model for the freezing point of water T at altitude a is:
T(a)= 0.0001a+32
The slope of this equation is the coefficient of the variable a. Since the slope is positive, it means the freezing point of water increases by 0.0001 degrees Fahrenheit when the altitude increases by 1 foot.
For example, when a=1000, the freezing point is:
T(1000)= 0.0001*1000+32 = 32.1°F
When a=1001, the freezing point is:
T(1001)= 0.0001*1001+32 = 32.1001°F
Note the increase of 1 foot in altitued meant an increase of 32.1001-32.1 = 0.0001°F
Answer:-5/7 i think that is wrong
Step-by-step explanation:
Answer:
8 13 14 15 18.
Step-by-step explanation:
The median (the middle number) is 14 so we have
x x 14 x x where x is a single number with each number being different (as there is no mode).
The mean is 13.6 so we have the total numbers
= 13.6 * 5 = 68.
The 4 numbers left must total 68-14 = 54 and the difference between the highest and lowest is 10.
I sense that the lowest and highest will add up to about 1/2 of 54 so:
Try 8 and 18 for these last 2 numbers
The list would be 8 x 14 x 18.
The 2 numbers left will add up to 54 - 26 = 28 . One of these must be < 14 and the other > 14. 13 and 15 would fit.
So a possible data set is:
8 13 14 15 18.
