Answer:
The mean would be 85 :)
Step-by-step explanation:
The first one is D. Y=-3+8x
The second one is G. -3/2x=y+2
Answer:
25 movies
Step-by-step explanation:
First, create the monthly costs for both plans:
Plan A:
A = x + 32
Plan B:
B = 2x + 7
Set these two expressions equal to each other, and solve for x:
x + 32 = 2x + 7
32 = x + 7
25 = x
So, the two plans will have an equal monthly cost after 25 movies.
Given a relative frequency table is made from data in a frequency table.
Frequency Table
G H Total
E 12 11 23
F 14 8 22
Total 26 19 45
Recall that the relative frequency table is obtained from the Frequency table by dividing each entry of the frequency table by the ovarall total of the frequency table.
Thus the relative frequency table of the frequency table above is given by:
Relative Frequency Table
G H Total
E 12/45 = 0.27 = 27% 11/45 = 0.24 = 24% 23/45 = 0.51 = 51%
F 14/45 = 0.31 = 31% 8/45 = 0.18 = 18% 22/45 = 0.49 = 49%
Total 26/45 = 0.58 = 58% 19/45 = 0.42 = 42% 45/45 = 1.00 = 100%
For the given relative frequency table with the missing value y being the value of the relative frequency of E and G.
Therefore, the value of y is 27%
