Answer:
5
Step-by-step explanation:
To obtain the total score for all the 20 students, we multiply the average score by the number hence
Total score for all 20 is 81*20=1620
Similarly, for the 19 students, the sum of their total score equals the product of the average and number of students hence
Total score for 19 readable is 19*85=1615
The difference between these two total scores ie for 20 and 19 students equals to the value of unreadable score. Therefore,
Difference=1620-1615=5
Therefore, the value of unreadable score is 5
Answer:
8
Step-by-step explanation:
0 = –x^2 + 4x – 2
This is of the form
ax^2 +bx +c
a = -1 b = 4 x = -2
The discriminant is
b^2 -4ac
4^2 - 4(-1)(-2)
16 - 8

Answer:
<u>Equations for each salesman:</u>
- A. p(s) = 65s
- B. p(s) = 40s + 300
- C. p(s) = 900
<u>When s = 0, s= 1, s = 10 each of the gets paid:</u>
- A. p(0) = 0, p(1) = 65, p(10) = 650
- B. p(0) = 300, p(1) = 340, p(10) = 700
- C. p(0) = p(1) = p(10) = 900
<u>The above numbers as ordered pairs:</u>
- <u> A B C </u>
- s = 0 | (0, 0) | (0, 300) | (0, 900)
- s = 1 | (1, 65) | (1, 340) | (1, 900)
- s = 10 | (10, 650) | (10, 700) | (10, 900)
Answer:
A
Step-by-step explanation:
So from 36 to 60 is add 24 and for 3 to 5 is add 2 so that gave u 24/2 that is = 12 and u do ur Y=MX+B 36=(12)(3)+b = 36=36+b then u subtract 36 = to 0 so B=0 and that how u get Y=12x.
