Answer:
the height of the rock 3.2 seconds after it is propelled
Step-by-step explanation:
<u><em>The complete question is</em></u>
The function h(t) = –16t2 + 28t + 500 represents the height of a rock t seconds after it is propelled by a slingshot
Let
t------> the time in seconds
h----> the the height of a rock after it is propelled by a slingshot in meters
we know that

For 
Find the value of h(t)

therefore
h(3.2) represent the height of the rock  seconds after it is propelled
 seconds after it is propelled
see the attached figure to better understand the problem
 
        
             
        
        
        
According to Sturge's rule, number of classes or bins recommended to construct a frequency distribution is k ≈ 7
Sturge's Rule: There are no hard and fast guidelines for the size of a class interval or bin when building a frequency distribution table. However, Sturge's rule offers advice on how many intervals one can make if one is genuinely unable to choose a class width. Sturge's rule advises that the class interval number be for a set of n observations.
Given,
n = 66
We know that,
According to Sturge's rule, the optimal number of class intervals can be determined by using the equation:

Here, n is equal to 66 and by substituting the value to the equation we get: 

k = 7.0444
k ≈ 7

1000 candy bars ... $350
1 candy bar ... $x = ?
If you would like to know what is the unit cost per candy bar, you can calculate this using the following steps:
1000 * x = 350 * 1
1000 * x = 350    /1000
x = 350 / 1000
x = $0.35
Result: She can buy 1 candy bar for $0.35, so the correct result would be B) $.35.
