Josef receives 3$ per hour spent doing chores. So, after x hours of chores, he receives 3x dollars. This money must be added to the 10$ he would receive no matter what, so the total expression is
7.
We can test the options against the given patterns: in pattern 1, we have one black hexagon and 6 white hexagons. Let's see which equations fit: if we substitute b=1 and w=6 we have:
A) 
- ok
B) 
- wrong
C) 
- ok
D) 
- wrong
E) 
- wrong
So, the only feasible answers are A or C, because all the other functions don't fit even the first pattern. Let's test the two survivors for pattern 2: we have two black hexagons and 8 white hexagons. Plugging b=2 and w=8 into A and C we have
A) 
- wrong
C) 
- ok
So, the answer is C, because it models correctly pattern 2 as well. For the sake of completeness, let's test this function against pattern 3 as well: we have 3 black and 10 white hexagons. Plugging b=3 and w=10 into C we have
C) 
- ok
So, C models correctly all patterns, and thus describe the general rule.

<span>When
a data value is converted to a standardized scale representing the
number of standard deviations the data value lies from the mean, we
call the new value a z-score.
A z-score is used to indicate how many standard deviation a value is from the mean.

The multiplicative rate is 9 if the table that shows an exponential function option fourth is correct.
<h3>What is an exponential function?</h3>
It is defined as the function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = a^x
where a is a constant and a>1
We have a table that shows an exponential function.
As we know the exponential function:
y = a(b)ˣ
Plug x = 1, y = 6
6 = ab ...1
Plug x = 2, y = 4
4 = ab² ...2
Divide equations 1 and 2
ab²/ab = 4/6
b = 2/3
Plug the value of b in the 1 equation.
a(2/3) = 6
a = 9
y = 9(2/3)×
The multiplicative rate = 9
Thus, the multiplicative rate is 9 if the table that shows an exponential function option fourth is correct.
