A. There is a positive correlation between the temperature and the amount of ice cream sold. This means that as the temperature increases the amount of ice cream also increases.
B. For the best fit you must calculate the slope between two points that are more-or-less representative of the entire graph. In this case it seems to have already done this with certain points so if you take the points (15,35) and (0,5) you can calculate the slope between these two points which is m=(35-5)/(15-0)=30/15=2. So the best fit slope for this particular case would be two and you would just draw a line through the graph at approximately the middle of the dots to best represent all of the data.
and the y-intercept is 5 so the approximate equation for the graph would be y=2x+5
Answer:
The answer depends on what the problem really is.
f(1/2) = 8
or
f(1/2) = 4
See below.
Step-by-step explanation:
This is the problem as it was posted:
y = f(x) = 16x
Let x = 1/2
y = f(1/2) = 16(1/2) = 8
Perhaps the problem is this:
If x is an exponent of 16 and not a factor, then the answer is:
It’s impossible to do this because…….. so that’s why it’s impossible
Answer:
x ≥ 12.5
Step-by-step explanation:
2(x-9) ≥ 17---Use Distributive Property
2x-18 ≥ 17
2x-18+18 ≥ 17+18
2x ≥ 25
2x/2 ≥ 25/2
x ≥ 12.5
I hope this helps!
Answer:
Step-by-step explanation:
From the question we are told that:
Height of child 
Height of child's shadow 
Height of tree's shadow 
Since position of Sun remains constant
Generally the equation for Height of tree h_t mathematically given by
