Answer:
Step-by-step explanation:
You need to first put the numbers in suitable catagories
0-120
120-130
130-140
140-150
then figure out the frequency of them
0-120=4
121-130=20
131-140=2
141-150=2
then put in a graph(sry its not very good i was in a rush)
Answer:
b)

Step-by-step explanation:
b) set up equations so they are equal to each other,



this is when f(x)=g(x) so our approximation was close.
c)solving it graphically is nearly impossible because the solution can be any value around the intersection. only way to be sure is to solve it symbolically.
Answer:
m= -16
Step-by-step explanation:
you would add 19 to -35 because you are trying to isolate the variable m.
we can convert any decimal to a fraction, by simply <u>using as many zeros at the bottom as there are decimals, and losing the dot atop</u>, now let's do so, notice we have 3 decimals, so we'll use 3 zeros.

Answer:
-7 degrees
Step-by-step explanation:
9am: 5 degrees(current temperature)
10am: 5-4=1 degrees(first hour)
11am: 1-4=-3 degrees(2nd hour)
12pm: -3-4= -7 degrees(3rd hour)
