Answer:
A. 3
B. 2.825
Step-by-step explanation:
Data obtained from the question include:
Number of bedrooms (x) > Frequency(f)
1 >>>>>>>>>>>>>>>>>>>>> 5
2 >>>>>>>>>>>>>>>>>>>> 10
3 >>>>>>>>>>>>>>>>>>>> 15
4 >>>>>>>>>>>>>>>>>>>> 7
5 >>>>>>>>>>>>>>>>>>>> 3
Mode =?
Mean average of bedrooms =.?
A. Determination of the modal average of bedroom.
The mode of a given set of data is the the value with the highest frequency.
Considering the table given in the question above, we can see clearly that 3 has the highest frequency. Hence 3 is the modal average of the bedroom is 3
B. Determination of the mean average of bedroom.
Mean = Σfx / Σf
Σfx = (1×5) + (2×10) + (3×15) + (4×7) + (5×3)
Σfx = 5 + 20 + 45 + 28 + 15
Σfx = 113
Σf = 5 + 10 + 15 + 7 + 3
Σf = 40
Mean = Σfx / Σf
Mean = 113 / 40
Mean = 2.825
Therefore, the mean average of bedroom is 2.825

(1) a = 16 , (2) x =4 , (3) x = 0 ,(4) n =-20 , (5) r = 20 and (6) x = -11
Step-by-step explanation:
(1) 6 = a/4 + 2
4 = a/4 (It is because when you bring +2 over to the left it will become 6 -2)
a = 16 (it is because of the fraction, so when you bring the divisor over it becomes x 4)
The following questions same as qns 1 too
(2) -6 + x/4 = -5
x/4 = 1
x = 4
(3) 9x -7 = -7
9x = 0
x = 0
(4) 0 = 4 + n/5
-4 = n/5
n = -20
(5) -4 = r/20 -5
1 = r/20
20 = r
(6) -1 = 5 + x/6
-6 = 5 + x
-11 = x
0 is the middle number between negative numbers and positive numbers. Since 1/2 is positive, we know that 1/2 is greater than 0.
