Answer:
About 25 guests (graph is attached).
Step-by-step explanation:
First we estimate the line of best fit. Using that line, we go to 85 on the x-axis (temperature) and then up to the line, to see what the y-value is. At the point where x = 85, the line appears to go through about 25 on the y-axis. Thus our estimate is 25 guests.

Answer:
Only natural numbers (i.e., non-negative integers) can be the exponents of variables in a polynomial.
Step-by-step explanation:
The exponent of variables in a polynomial should be natural numbers (,
,
,
,
.)
is equal to
. In this expression,
is the variable. Its exponent is
, which isn't a natural number.
- On the other hand,
is equivalent to
. The exponent of variable
, which is indeed a natural number.
isn't a polynomial because the exponent of variable
isn't a natural number. On the other hand,
is indeed a polynomial over the set of real numbers.
