Hope this helps!!
Answer
A. 129.3
B. The students ages can be any number within the ranges, so having the middle number wont represent the other possible heights.
Step by step
'h' is the number between the surrounding number, the first would be 122.
You need to multiply the hight by frequency of each one,
122x7 =854
126x8=1008
130x13=1690
134x9=1206
138x3=414
Add them up = 5172
5172/40 =129.3
Answer:
Graph of a one-to-one function if f is a one-to-one function then no two points (x1,y1), (x2,y2) have the Same y-value. Therefore horizontal line cuts the graph of the equation y = f (x) more than omce. Horizontal line test: A graph passes the horizontal line test if each horizontal line cuts the graph at almost once.
Answer:
<em>Hence, it will take</em><em> 9 seconds </em><em>for kirk to run </em><em>63+9=72 yards </em><em>and catch upto Max. </em>
Step-by-step explanation:
Let 'y' represents the time Max and Kirk took to meet.
Let the distance between the destination where they will meet from the place where Max is be: x yards
So the distance of destination from initial position of kirk is x+9 yards ( As Max is given a head start of 9 yards)
- As speed of Max is 7 yards per sec.
And 
Hence,


- also speed of kirk is 8 yards per second.
By the similar definition of speed we have:

Hence (1) and (2) are the required system of equation.
So on solving the system of equations by elimination method we have:
y=9 and x=63.
Hence, it will take 9 seconds for kirk to run 63+9=72 yards and catch upto Max.
