Which function is represented by the graph?
(08.02 MC)
The two dot plots below show the heights of some sixth graders and some seventh graders:
Two dot plots are shown one below the other. The title for the top dot plot is Sixth Graders and the title for the bottom plot is Seventh Graders. Below the line for each dot plot is written Height followed by inches in parentheses. There are markings from 52 to 57 on the top line and the bottom line at intervals of one. For the top line there are 2 dots above the first mark, 1 dot above the second mark, 1 dot above the third mark and 2 dots above the fourth mark. For the bottom line, there are 2 dots for the fifth mark, there are 4 dots above the sixth mark.
The mean absolute deviation (MAD) for the first set of data is 1.2 and the MAD for the second set of data is 0.4. Approximately how many times the variability in the heights of the seventh graders is the variability in the heights of the sixth graders? (Round all values to the tenths place.)

Nicholas bought a new computer for $1,250. The value of the computer decreases by 17 percent every year. Approximately how much is the computer worth after 5 years?
Answer: The computer worth $ 492.38 after 5 years.
Step-by-step explanation:
If the value of an item depreciates by r% then the value of the item after t years is given by :-
[tex]V=V_0(1-\dfrac{r}{100})^{t}[/tex]
, where [tex]V_0[/tex] = initial value.
Given: [tex]V_0[/tex] =$1,250, r=17% , t= 5 years
Then, the value of computer after 5 years = [tex]1250(1-\dfrac{17}{100})^5[/tex]
[tex]=1250(0.83)^5\\\\=1250(0.39390)\\\\\approx492.38[/tex]
Hence, the computer worth $ 492.38 after 5 years.

Christopher went into a restaurant and bought 5 hamburgers and 10 drinks, costing a total of $52.50. Wyatt went into the same restaurant and bought 2 hamburgers and 9 drinks, costing a total of $31. Write a system of equations that could be used to determine the price of each hamburger and the price of each drink. Define the variables that you use to write the system.
Answer:
Step-by-step explanation:
Let the price of each hamburger be a and the price of drink each be b.
5a+10b=52.50
2a+9b=31
5a+10b=52.50
a=10.5-b
2(10.5-b)+9b=31
7b=10.5
b=1.5
a=10.5-1.5
a.9
∴The price of each hamburger is $9 and the price of each drink is $1.5

Answer:
1) 23a + 18
2) 23a - 6
3) 23a - 18
4) -16
5) 7a - 6
Step-by-step explanation:
Use the distributive property (if it is subtraction remember to distribute the negative sign as well)
1) 3(5a + 2) + 4(2a + 3) = (15a + 6) + (8a + 12) = 23a + 18
2) 3(5a + 2) + 4(2a - 3) = (15a + 6) + (8a - 12) = 23a - 6
3) 3(5a - 2) + 4(2a - 3) = (15a - 6) + (8a - 12) = 23a - 18
4) 3(5a - 2) - 5(3a - 2) = (15a - 6) - (15a +10) = 15a - 6 - 15a - 10 = -16
5) 3(5a + 2) - 4(2a + 3) = (15a + 6) - (8a + 12) = 15a + 6 - 8a - 12 = 7a - 6
