Answer:
See the figure attached
Step-by-step explanation:
Let's call :
x: positive response
y: negative response
then the score is:
2x - 3y
A career placement test eliminates a profession when a person receives a score of 18 or less, that's represented by the following inequality:
2x - 3y ≤ 18
B: x
T: 3x
R: x + 8
x + 3x + (x+8) = 68
5x + 8 = 68
5x = 60
x = 12
B: 12
T: 36
R: 20
Answer:
Answer is d
Step-by-step explanation:
- A computer programmer has a 35 change of finding a bug in any given program.
- we have to find probability that she finds a bug within the first 3 programs she examines
- success = 0.35, failure = 0.65
- She get a bug in the first program itself
- p = 0.35
- She get a bug in 2nd program
- q = 0.65×0.35 =0.2275
- She get a bug in the 3rd program
- r = 0.65×0.65×0.35
- r = 0.147875
- Add all the three probabilities for answer
- P = p+q+r
- P = 0.35+0.2275+0.147875
- P = 0.725375
- P = 0.73
- The probability of the answer is 0.73
Answer:
29x - 12
Step-by-step explanation:
Step 1: Use the distributive property
8(x-5) + 7(3x+4)
= 8x - 40 + 21x + 28
Step 2: Combine like terms
= 29x - 12
